9 Best Grill Parts Replacement (November 2026)
The best grill parts replacement include the Uniflasy Grill Replacement Parts for Charbroil Performance for older Char-Broil Performance grills, the Uniflasy Grill Grates for Nexgrill Replacement Parts for cast-iron Nexgrill grates, and the Uniflasy Spirit E310 Grill Parts Replacement Kit for Weber Spirit 300 Series repairs.
On this page (6 sections)
The best grill parts replacement choice is the Uniflasy Char-Broil Performance kit for older 4-burner grills, while the Uniflasy Nexgrill grates are the strongest choice when only the cooking surface needs replacing.
For heat plates, match the exact size before choosing a material or pack size.
Grill parts replacement is a compatibility problem first.
A burner, grate, heat shield or grease tray can look close and still fail to fit if the model number, mounting position or dimensions differ.
That is why this guide starts with the worn part and the grill label, not with a brand name or a general claim of universal fit.
Use this guide for outdoor gas-grill components.
If your countertop appliance is electric, start with What Does Smokeless Mean on an Indoor Grill? and choose parts made for that appliance family.
Outdoor gas parts and indoor electric accessories need different shapes, supports and heat paths.
A part that works on a gas grill will not automatically work on a countertop model.
The picks below are ordered by the repair job they address.
A full kit makes sense when burners, heat plates and ignition parts are worn together.
A grate only set makes sense when the frame and burners still work but the cooking surface is cracked or failing.
Heat plates need a size check before material matters.
Grease trays need depth, width and height checks before assembly matters.
Keep the old part beside the new one during set-up.
Compare length, width, shape and resting points before you light the grill.
That simple habit prevents most wrong-size orders and makes replacing one part at a time much easier.

The best grill parts replacement picks by repair job
The best replacement part depends on whether you need a full rebuild, a new cooking surface, heat protection or grease control. These picks are ordered by score, with model fit carrying more weight than broad compatibility language.
Uniflasy Grill Replacement Parts for Charbroil Performance: Best for older Char-Broil Performance grills
- 4 burners
- 4 heat plates
- 3 adjustable crossover tubes
- 2 ignitors
This complete kit suits older Char-Broil Performance gas grills when the burners, heat plates and crossover tubes all need replacement.
Pros
- Complete repair kit
- Adjustable crossover tubes
- Wide model list
Cons
- Does not fit newer models
- Requires exact model and size checks
The Uniflasy Char-Broil kit is the most complete option here for older Char-Broil Performance gas grills.
It includes 4 stainless steel burners, 4 stainless steel heat plates, 3 adjustable crossover tubes and 2 ignitors.
The burners measure 17 3/4 x 3/5 in, while the heat plates measure 16 15/16 x 2 1/12 in.
The crossover tubes adjust from 5 to 9.5 in, which helps match the spacing on compatible older models.
That adjustment is useful when the burner spacing on your grill sits within that range.
It still does not make the kit universal for every Char-Broil grill.
The kit covers named 2-, 4-, 5- and 6-burner Char-Broil Performance models.
It does not fit newer models 463365021, 463365522 or 463352521, so check the grill label and compare the old parts before ordering.
This distinction matters because older and newer Performance models can use different part sizes.
Stainless steel is chosen here for heat resistance and corrosion resistance in the stated construction.
That helps with a grill that sees frequent outdoor use and regular cleaning.
Choose it when several internal components are worn at once.
If only the grate is damaged, a smaller grate replacement may avoid replacing usable burners and heat plates.
Uniflasy Grill Grates for Nexgrill Replacement Parts: Best for cast-iron Nexgrill grates
- 2 grates
- 17 x 13 1/4 in each
- 17 x 26 1/2 in total
- Matte cast iron
These 2 cast-iron grates fit a wide group of Nexgrill models and suit cooks who want strong heat retention and visible sear marks.
Pros
- Cast iron retains heat
- Broad model compatibility
- 2-piece replacement
Cons
- Heavy 13 lb item weight
- Fit still depends on model
These Uniflasy grates suit Nexgrill owners who want a cast-iron cooking surface.
The pack includes 2 matte cast-iron grates, each measuring 17 x 13 1/4 in, for a combined 17 x 26 1/2 in surface.
Cast iron holds heat well and can produce strong sear marks.
It is also heavier than stainless steel, so check that the replacement pieces match the grill's support points before installation.
That weight is part of the trade-off to consider for daily lifting and cleaning.
The stated material is meant to resist chipping and to clean more easily than some enamelled alternatives.
Even heat distribution across the surface helps with more consistent cooking.
The grates fit named Nexgrill, Char-Broil, Expert Grill, Cuisinart, Kenmore, Members Mark, Uberhaus, Uniflame and K-Mart models.
Model numbers include Nexgrill 720-0888, 720-0888N, 720-0830H and related versions.
Check your model number against that list before ordering.
Also compare the 17 x 13 1/4 in size for each piece with your old grates.
For a broader look at this brand family, compare these with the best Ninja indoor grill replacement parts.
The appliances differ, but the same model-check habit applies.
Uniflasy Spirit E310 Grill Parts Replacement Kit: Best for Weber Spirit 300 Series repairs
- 5 flavorizer bars
- 3 main burners
- 1 crossover tube
- Porcelain-enameled steel and 304 stainless steel
This combined kit replaces both flavorizer bars and burner tubes on compatible front-control Weber Spirit and Spirit II 300 Series grills.
Pros
- Combines 2 repair groups
- 304 stainless burner tubes
- 5 flavorizer bars
Cons
- Not for side-control models
- Model years and controls matter
This Uniflasy kit is built for front-control Weber Spirit and Spirit II 300 Series grills.
It combines 5 porcelain-enameled steel flavorizer bars with 3 main stainless steel burners and 1 crossover tube.
The flavorizer bars measure 15.3 x 2.6 x 2.5 in.
The burners measure 18 in on the left and right, 17.75 in in the center, and 15.25 in for the crossover tube.
Those different lengths matter for set-up.
Each burner needs to sit in its intended position for even flame distribution.
The porcelain-enameled bars help protect burners from grease drippings and help distribute heat.
They also help create the smoke that gives grilled food flavour.
Compatibility includes E-310, S-310, E-320, S-320, E-330, S-330 and SP-330 models from the stated series, plus Spirit II and GS4 II 300 Series models such as SP-310 and SP-330.
It is not for side-control models.
That control position is a key fit check, so confirm it on your grill before ordering.
Choose this when both heat-protection bars and burner tubes need attention.
For a different brand, see the best Hamilton Beach grill replacement parts guide.
CaptainGrill Grease Tray with Catch Pan: Best for adjustable drip-tray width
- 24 to 30 in adjustable width
- 15 1/2 in depth
- Catch pan
- Galvanized steel
This tray suits grills needing a replacement grease system with adjustable width, but you should measure the existing tray before ordering.
Pros
- Adjustable width
- Includes catch pan
- Sloped grease channel
Cons
- Needs assembly
- Width range limits fit
The CaptainGrill tray is the best fit-focused option when your grill needs a replacement grease tray with adjustable width.
It adjusts from 24 to 30 in wide, measures 15 1/2 in deep and stands 2 3/4 in high with the catch pan.
The galvanized steel assembly weighs 3.5 lb including the catch pan.
It has a sloped center channel and angled sides that direct grease toward the drain opening.
That sloped design helps with cleaning because runoff has a clear path to the catch pan.
The material is stated to resist corrosion, rust and heat in normal grill use.
The tray arrives as 3 pieces with brackets, bolts, nuts and a grease cup.
Assembly takes place after choosing the width, so measure your current tray and confirm the available space before installing it.
Set the width to your measured space rather than using the widest setting by default.
This option suits several Dyna-Glo, Nexgrill, Kenmore, Backyard Grill, BHG and Uniflame models.
It is a poor choice if your grill needs a fixed tray outside the 24 to 30 in range.
Depth and height also need to fit the space below your grill.
Replace parts Porcelain Steel Heat Plate: Best for 4-piece porcelain heat plates
- 4 heat plates
- 14 9/16 x 3 3/8 in
- Porcelain steel
- Original part number 1363786
These 4 porcelain steel heat plates suit several Nexgrill, Grill Master, Sunbeam and related gas grills with matching dimensions.
Pros
- 4-piece pack
- Wide model list
- Protects burners from drippings
Cons
- Exact dimensions still matter
- Only replaces heat plates
These Replace parts heat plates are a good choice for grills that use four fixed shields measuring 14 9/16 x 3 3/8 in.
The pack uses porcelain steel and replaces original part number 1363786.
The plates fit named Nexgrill models from 720-0697 through several 720-09-series models.
Compatibility also covers selected Sunbeam, Grill Master, Char-Broil, Dyna-Glo, Kenmore, Kitchen Aid, Members Mark, Uberhaus, Duro, Tera Gear and Coleman grills.
That broad list still depends on the exact size.
Porcelain steel sits between the burner and cooking surface to shield the burner from grease and food debris.
It also helps distribute heat more evenly across the cooking surface.
That can reduce flare-ups caused by direct drippings on the burner.
Match the original plate's length, width and shape before ordering.
A plate that is too short or too narrow will not cover the burner as intended.
If you want stainless steel in the same main dimensions, compare the best Cuisinart Griddler accessories only for appliance-specific ideas, then return to your outdoor grill's model and part measurements.
Adviace Universal Adjustable Grill Heat Plates/Heat Tents/Burner: Best for adjustable heat shields
- 3 heat plates
- 11.75 to 21 in adjustable length
- 3.75 in width
- 1.2 mm porcelain steel
The adjustable design helps when a fixed replacement plate does not match your grill's length, provided the 3.75 in width works.
Pros
- Wide length adjustment
- 3-piece pack
- Includes installation hardware
Cons
- Universal fit is not guaranteed
- Width is fixed
Adviace heat plates suit grills where a fixed replacement does not match the available length.
Each of the 3 porcelain steel plates uses a 2-piece telescoping design and adjusts from 11.75 to 21 in long.
The plates are 3.75 in wide and use 1.2 mm porcelain-coated steel.
The box includes M5 bolts and wing nuts for assembly.
That hardware helps you set the length to the burner space in your grill.
Telescoping length is the main benefit here.
It gives more flexibility than a fixed plate when the old shield length is hard to match.
Named compatibility includes Brinkmann, Char-Broil, Grill Master, Kenmore and Master Forge models.
The fixed width still matters, so measure the original heat shield before treating this as a universal solution.
A width that is too wide or too narrow can leave gaps or sit poorly.
Choose this option when length is the main fit problem.
For a grill using a fixed 14 9/16 x 3 3/8 in shield, the Direct Parts DP130 below may be easier to compare.
Direct Parts DP130: Best for stainless heat-shield swaps
- 4 heat plates
- 14 9/16 x 3 3/8 in
- Stainless steel
- Smooth surface
This 4-pack is a practical alternative to porcelain plates when your grill uses the same 14 9/16 x 3 3/8 in size.
Pros
- Stainless steel construction
- 4-piece pack
- Smooth surface for cleaning
Cons
- Exact size is critical
- Only replaces heat shields
Direct Parts DP130 provides 4 stainless steel heat plates measuring 14 9/16 x 3 3/8 in.
It targets the same broad model families as several fixed-size porcelain heat plates, including Sunbeam, Nexgrill, Grill Master, Char-Broil, Kitchen Aid, Members Mark and Uberhaus.
The smooth stainless surface is intended to be easier to clean with soap, water and a grill brush.
Dry the plates fully after cleaning so moisture does not remain on the metal during storage.
That drying step helps with care between uses.
Stainless steel is a practical choice when you want a corrosion resistant shield with a smooth surface.
It will not solve fit if your size differs.
Named Nexgrill fits include 720-0697, 720-0737, 720-0783E, 720-0825, 720-0830A, 720-0830D and several later models.
The model list does not replace a dimension check.
Pick this set when you want stainless steel and the 4-piece size matches your old shields.
Pick the porcelain steel option when its listed material and model match are more useful to you.
FlameDuty Stainless Cooking Grate: Best for a broad Nexgrill repair kit
- 2 cooking grates
- 4 burner tubes
- 4 heat tents
- 4 ignitors
This kit covers cooking grates, burners, heat tents and ignitors for several Nexgrill 4- and 5-burner models.
Pros
- Several components together
- Stainless steel parts
- Includes ignitors
Cons
- 13.59 lb item weight
- Compatibility is model-specific
The FlameDuty kit is a broad Nexgrill repair package with 2 stainless cooking grates, 4 burner tubes, 4 heat tents, 4 ignitors and 8 screws.
The grates measure 17 x 13.3 in each, the burner tubes measure 14 7/8 x 1 in, and the heat tents measure 14 9/16 x 4 3/16 in.
It fits named Nexgrill 4- and 5-burner models, including 720-0830H, 720-0783E, 720-0864, 720-0888, 720-0896CA and 730-0898.
The stainless steel parts resist rust and corrosion according to the stated construction details.
That material choice suits a set that includes both cooking and internal parts.
Including ignitors helps when ignition is part of the repair problem.
Choose it when several Nexgrill components need replacement at the same time.
If you only need heat plates, this kit includes more parts than necessary.
The total item weight is 13.59 lb, so storage and handling are worth considering.
For accessory ideas tied to another appliance line, see the best Ninja Foodi grill accessories guide.
Do not use appliance accessories as proof of outdoor gas-grill compatibility.
Welbocom Charbroil grill replacement part: Best for newer Char-Broil Performance II grills
- 4 burners
- 4 heat plates
- 3 adjustable crossover tubes
- 2 igniters
This kit targets newer Char-Broil Performance II 2-, 3-, 4-, 5- and 6-burner model families, with different quantities needed for some larger grills.
Pros
- Targets 2021 and newer models
- Complete 4-burner kit
- Adjustable crossover tubes
Cons
- Does not fit older Performance models
- Larger grills may need 2 sets
Welbocom targets newer Char-Broil Performance II grills from 2021 and newer.
The 4-burner kit includes 4 stainless burners, 4 heat plates, 3 adjustable crossover tubes and 2 igniters.
The burners measure 15 3/8 x 5/8 in, and the heat plates measure 15 1/2 x 1 1/2 in.
The crossover tubes fit burner distances from 5.0 to 8.9 in.
That range helps match spacing on the listed Performance II models.
The kit is compatible with propane and natural gas according to the stated details.
Named compatibility includes Performance II 420 models, along with selected 375, 300, 540 and 480 families.
It does not fit older Char-Broil Performance models such as 463377319, 463342119 and 463376519.
That older and newer split is the main buying decision here.
For 5- and 6-burner Performance II grills, the listing notes that 2 sets may be required.
Choose it when your grill label confirms a Performance II model.
For model-specific accessories, compare the best Ninja AG301 accessories only as a reminder that exact appliance names matter.
How do you match replacement parts for grills?
Match the model number, component type and measurements before choosing replacement parts for grills.
Start with the label on the grill, then remove the old part only after the grill is cool and compare its length, width, shape and mounting points.
A model number is more useful than a brand name alone.
The same brand can use different burner lengths or heat plate shapes across product families, as shown by the separate older and newer Char-Broil kits here.
That is why a part that fits one Performance model may not fit another Performance model.
Check the exact suffix numbers on the label, not just the family name.
For fixed heat plates, measure the longest dimension and width.
Write both numbers down and compare them with the replacement size.
For adjustable plates, check both the available length range and the fixed width.
Length flexibility does not fix a width mismatch.
For burners, compare length and diameter as well as the position of each tube.
Left, right and centre burners can be different lengths in the same grill.
For grates, compare the number of pieces and the total cooking area.
A 2-piece set may fit a wide grill, but each grate still needs to rest correctly on the original supports.
Check the support points at the front and back before you order.
For crossover tubes, measure the distance between burners.
Adjustable tubes help only when your spacing falls inside the stated range.
For grease trays, measure depth, width range and height.
Leave room for the catch pan and access for cleaning.
Also check that the tray can slide in without bending or forcing it into place.
Keep the old part until the new one is fitted and the grill has been checked.
That makes it easier to spot a size problem before the repair is finished.
What are the main types of replacement parts for grills?
The main types are grates, burners, heat plates, crossover tubes, igniters and grease trays.
Each solves a different failure point, so replacing one part does not restore every worn component.
Grates form the cooking surface.
Cast iron can retain heat strongly, while stainless steel is often chosen when a lighter, corrosion-resistant material suits the existing grill design.
Cast iron is good for searing because it holds heat well during cooking.
Stainless steel can be easier to lift and clean for some cooks.
Burners create the gas flame, and crossover tubes help carry ignition between burner sections in compatible systems.
Heat plates sit above the burners to protect them from drippings and spread heat.
A damaged burner can cause uneven flames, while a damaged heat plate can cause flare-ups from drippings.
Igniters help start the burners, and a worn igniter can make a working burner hard to light.
Grease trays collect runoff below the cooking area.
A tray with an adjustable width can help with fit, but the grill's depth and support structure still need to match.
A grease tray does not improve cooking heat, but it helps with clean-up and runoff control.
A complete kit makes sense when several related pieces are damaged.
A single grate or heat plate is more efficient when the rest of the grill remains in usable condition.
That approach also helps you avoid replacing parts that still fit and still work.
Choose the part by its job first, then by model and size.
That order keeps the repair focused and makes the choice easier to explain.
How should you install and care for grill replacement parts?
Install grill replacement parts only after the grill is cool, the fuel is shut off and the old components are removed safely.
Use the model instructions where available, and compare each new part with the old one before fastening anything.
Clean grease and debris from the support areas before placing new grates or heat plates.
Keep burners and igniters aligned with their original positions, and do not force a part that does not sit naturally.
Some kits include adjustable crossover tubes, bolts, wing nuts or other hardware.
Set adjustable pieces to the measured spacing rather than assuming the longest or shortest position will fit.
Tighten hardware evenly and check that grates rest level on their supports.
After cleaning, dry metal parts fully.
Direct Parts specifically recommends drying stainless heat plates with a towel after using soap and water.
That step helps prevent moisture from sitting on the metal during storage.
For cast iron grates, follow the care approach that suits cast iron and the grill maker guidance.
Replace parts that are cracked, badly rusted, warped or no longer support the cooking surface.
If a replacement does not match the old dimensions, stop and recheck the model number before lighting the grill.
More guides on this topic
Which grill parts replacement option should you choose?
Choose the Uniflasy Char-Broil Performance kit for an older compatible Char-Broil grill needing several internal parts. Choose the Uniflasy Nexgrill grates when cast iron and a 2-piece cooking surface are the main needs.
Pick the Weber Spirit kit for compatible front-control 300 Series grills. Choose CaptainGrill when an adjustable grease-tray width from 24 to 30 in matches your current tray.
For heat plates, choose Replace parts or Direct Parts when 14 9/16 x 3 3/8 in is the correct size. Choose Adviace when the 11.75 to 21 in adjustable range solves your length problem.
Finally, choose FlameDuty or Welbocom only after confirming the exact model family and component dimensions. The best grill parts replacement is the one that fits your grill safely and replaces the part that is actually worn.

Frequently asked questions
How do I choose grill parts replacement pieces?
Match the grill brand, model number, part type and dimensions before ordering. A burner kit may include heat plates and crossover tubes, while a grate or grease tray solves only one worn-part problem.
Measure the old component and compare its shape, length and width with the replacement.
Are grill replacement parts universal?
Some parts have adjustable dimensions, but grill replacement parts are rarely universal in practice. Adviace heat plates adjust from 11.75 to 21 inches, while other options here fit named model groups and fixed sizes.
Treat the word universal as a starting point, not proof of fit.
What grill part should I replace first?
Replace a damaged burner, heat shield, grate or grease tray based on its condition and role. A cracked grate affects the cooking surface, while a damaged burner or heat plate can affect flame distribution and grease protection.
Replace only the worn component when the rest of the grill remains usable.
Can I use indoor grill accessories on an outdoor gas grill?
No. Indoor electric grill accessories and outdoor gas-grill parts are different categories.
Outdoor replacement parts must match the grill's burners, heat plates, grates or grease system.
For background, read How Do Indoor Electric Grills Work? before mixing parts between grill types.
