Rust-eaten burner tubes and warped heat plates turn a decent cookout into a grease-fire gamble. Swapping worn parts instead of the whole grill is almost always cheaper and easier. This guide sorts the replacement burners, heat shields, grates, and drip trays that actually fit common Nexgrill, Charbroil, and Kenmore models, so you get even flames and clean sear marks without guesswork.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You can keep your old Nexgrill or Charbroil running like new without buying a whole new grill. These bbq grill parts—burner tubes, heat plates, and cooking grates—cost a fraction of a full replacement, so you fix the problem without emptying your wallet.
Our Picks at a Glance
How To Choose The Best BBQ Grill Parts
Replacing grill parts hinges on exact measurements and model numbers, not brand names. The biggest mistake is ordering by grill brand alone. — a “Nexgrill” part can vary by several inches depending on the burner count and year. Measure your old part and find the model number on the back of the grill before you add anything to the cart.
Match the Model Number, Not the Brand Name
Every part listing here is built around specific model codes like 720-0830H or 463241113. Those numbers on the back of your grill tell you exactly which burner count and layout you have. Cross-check that code against the compatibility list, then measure the old part’s length and width — most listings give dimensions like 14.6″L x 4.2″W, and a mismatch of even half an inch means a loose or cramped fit.
Choose the Right Material for the Job
Burner tubes come in stainless steel or cheaper coated steel; stainless resists rust and heat far longer, which is why most pickups here use it. Heat plates (also called flame tamers) are often porcelain-coated steel — the coating spreads heat and blocks flare-ups while protecting the burner below. Cooking grates are where cast iron shines: it holds heat and leaves proper sear marks, though it needs a light oiling after each cook to stay rust-free.
Decide Between a Single Part and a Full Kit
If only your burners are rotted, a dedicated burner set is the budget move. But if the grill is several years old and multiple parts are rusted, a kit with burners, heat plates, and crossover tubes costs barely more and refreshes everything at once. Check how many pieces come in the pack — a 4-burner grill needs four burners, not two.

In‑Depth Reviews
1. Unicook 14.6 Inch Grill Heat Plates, 6 Pack
Our pick — over 4.5★ from 500+ verified ratings; the strongest balance of quality and price.
The crowd-favorite heat shield that revives an old grill’s look in minutes.
Slide these flame tamers in and flare-ups stop, while heat spreads evenly across your cooking surface. At 14.6″L x 4.2″W with a 20GA thickness (about 0.036 inches of steel), they take regular grilling abuse and shield your burners underneath. Buyers report they fit perfectly on HD Char Grill models, with one noting: “These grill plates fit perfectly on our grill.”
Compatibility is the real strength here: this 6-pack covers a long list of Nexgrill models from the 2-burner 720-0864 up to the 6-burner 720-0898, plus Kenmore and Backyard Grill models. The heavy-duty porcelain steel coating is what buyers praise most — the fit earns the top mention with 41 callouts, and quality follows close behind at 32. The smooth surface wipes clean with a towel and degreaser, so maintenance is a two-minute job.
At 4.16 pounds for the set, these are noticeably heavier than a bare-bones replacement, which tracks with the durable feel owners describe. The one honest caveat: a few owners mention the fit is good but not flawless on every grill model, so double-check your original part dimensions before ordering. Homepro Manufacturing backs these, and the porcelain coating means they should outlast a single season of heavy use.
What wins people over
- Porcelain steel coating resists rust and spreads heat evenly
- Exact dimensions match most Nexgrill and Kenmore models
- Tool-free install in minutes, easy to wipe clean
Check before you buy
- Not a universal fit — verify your grill’s model number first
- Heavier than some alternatives at 4.16 pounds
Reach for these if: your heat plates are rusted or warped and you want a durable, easy swap for a Nexgrill or Kenmore grill.
Look elsewhere if: you own a grill model not on the compatibility list — measure first to avoid a loose fit.
2. Criditpid Grill Burner Tubes, 6 Pack
Six stainless burners that slip on in seconds and revive a tired 6-burner Nexgrill.
If flames on your old grill dance unevenly, rotted burner tubes are usually the cause. These stainless steel tubes, each 14 7/8″ x 1″, replace the entire gas rail on a 6-burner Nexgrill. Customers note “my husband said that they fit perfectly and the value for the money was great.” The slip-on install takes minutes with no special tools, and owners say flames burn evenly across the whole bar.
The compatibility list is enormous: 26 Nexgrill model codes from 720-0783E through 720-0969, plus Kenmore, Kitchen Aid, BBQ Pro, Members Mark, and Backyard Grill models. Stainless steel gives you strong corrosion and rust resistance, which is what you want in a part that lives right above the flames. Buyers praise the fit most — 47 callouts — with quality close behind at 38 mentions.
There are two honest trade-offs to weigh. Durability gets mixed feedback, with some owners reporting tubes burning out after about two dozen barbecues — so this is a solid value refresh, not a lifetime part. And the pack doesn’t include screws or pins, which a few buyers flagged as an annoyance. At 2.07 pounds, the whole set is light enough to handle easily during install.
Why it’s a steal
- Stainless steel resists rust and heat wear
- Massive Nexgrill and Kenmore compatibility list
- Easy slip-on install, even flame distribution
Know the limits
- No mounting screws or pins included
- Some units show wear after heavy use
Grab these if: you want the cheapest path to revive an old 6-burner grill without buying a new one.
Skip them if: you grill constantly and need maximum longevity — buy screws separately and manage expectations.
3. Parts Kit DG101 for Charbroil
Everything a tired Charbroil needs in one box — burners, heat plates, and crossover tubes.
This 11-piece kit is the closest thing to a full grill resurrection you can buy as parts. Inside you get 4 stainless steel burners at 15 7/8″ x 1″, 4 porcelain steel heat plates at 16″ x 3 13/16″, and 3 stainless crossover tubes at 6 3/8″ long—the complete fire system for a 4-burner Charbroil. Owners say install takes about 10-15 minutes, and the burners light smoothly in one attempt, with channels letting all burners ignite together.
The model coverage spans the Charbroil Performance, Commercial, and Designer lines — from 461261508 up through 463269806 — plus part numbers like G413-5000-01 and 80005703 for burner replacements. One reviewer noted “it’s been working well for past 3 summers by, it was easy to install,” which speaks to real staying power. The included crossover tubes are a big deal: they’re what carry the flame from burner to burner so you don’t have to light each one separately.
The known wrinkle is the included screws — several owners found them unusable and recommend keeping screws from your old grill or grabbing a few from a hardware store. It’s a minor hassle given the kit costs about the same as a single flame shield at a home improvement store. At 4 pounds, the whole set has a substantial, heavy-duty feel that matches the “much heavy, more durable” promise.
The all-in-one play: for the cost of one store-bought heat plate, you get the full fire system rebuilt — the crossover tubes alone make this worth it.
One real catch: the included sheet metal screws are widely reported as unusable, so budget for separate hardware.
Best for: Charbroil owners with multiple rusted parts who want one order that refreshes the whole grill.
Not for: anyone expecting plug-and-play hardware — set aside your old screws before you start.
4. Hongso 15 3/8″ Tube Burner Kit
The stainless savior for Kenmore grills, igniting evenly and outlasting the original.
If your Kenmore or Sears grill has a burner that won’t light or burns unevenly, this 4-pack of 15 3/8″ x 1″ stainless steel tubes is the targeted fix. The compatibility list covers 17 Kenmore model numbers plus Outdoor Gourmet, Members Mark, BBQ Pro, and even Coleman 9998. Reviewers point out the old tubes slide right out and the new ones slide right in — a tool-free swap that takes minutes.
What wins people over here is the value — it’s the top-mentioned aspect with 36 callouts. Shoppers say it beats buying a whole new BBQ and outperforms the “universal” burners at big-box stores, which one owner said work 100% worse. The stainless steel is the other big draw: owners confirm these are truly stainless, which is why one expects them to outlast the original that lasted 16 years. Installation is the second-most-praised aspect at 28 mentions.
Durability is the honest mixed bag — some buyers report several months of solid service, while others say the burners lasted around 7 months before needing attention. A few also noted a small port gap creates a “wooshing” sound on ignition, though it doesn’t affect cooking. At just 9.6 ounces for the set, these are the lightest burners here, so handle them with care during install.
Value leader: the price-per-burner math beats the universal options at hardware stores, and owners say the ignition is smoother.
The trade-off: longevity is a roll of the dice for heavy users — some see 7 months, some see years.
Perfect for: Kenmore owners who want a cheap, easy burner swap that ignites cleanly every time.
Think twice if: you grill nearly every day and need parts that go multiple seasons without question.
5. Universal Grease Tray with Catch Pan
The adjustable drip tray that keeps grease from turning your patio into a hazard.
Without a working grease tray, dripping oil lands on your deck and turns cleanup into a scrubbing session. This one adjusts from 24″ to 30″ wide, which is what makes it compatible across Dyna Glo, Nexgrill, Kenmore, Backyard Grill, BHG, and Uniflame models — you set the width to match your grill’s firebox. The 400ML collection capacity means fewer trips to empty it mid-cook.
Built from gauge 430 stainless steel, this tray is corrosion-resistant and heat-resistant, which owners say beats the original pan that didn’t last even 1-1/2 years. Fit is the top-praised aspect at 45 callouts, with quality close behind at 41. The added handles prevent slips and spills when you pull the tray out hot, and the rounded corners won’t scratch your hands — a thoughtful touch for a part you handle after every cook.
Assembly is where opinions split. Some owners say it bolts together easily with the included tool, while others found the instructions poor and had to be careful not to cut themselves on edges during setup. It takes about 5 minutes to install, and the 3-piece design lets you customize the length. Gloves are included, which suggests the edges deserve respect on some units.
Why it earns its spot
- Adjustable width fits multiple grill brands
- Thick stainless resists rust far longer than stock pans
- Handles make hot removal safe and easy
Assembly notes
- Instructions could be clearer for first-time builders
- Some units have sharp edges — use the included gloves
Reach for this if: your original drip pan rusted through and you want a sturdier, adjustable replacement.
Be prepared to: spend a few careful minutes on assembly and keep gloves nearby for the edges.
6. Utheer Grill Parts Kit for Nexgrill 4 Burner
The complete Nexgrill 4-burner refresh that includes the screws everyone forgets.
What makes this kit stand out is the hardware pack — it includes the screws to hold the burners and mount the igniter electrodes, so you don’t make a separate trip to the hardware store. You get 4 stainless steel heat plates at 14.6″ x 4.3″ x 1.4″ and 4 stainless burner tubes at 14-7/8″, the exact fire system for a Nexgrill 4-burner 720-0830H or 720-0888. Owners say putting it together was a breeze and the grill works like new again.
Quality is the aspect buyers mention most by far at 64 callouts, with functionality second at 45. The stainless is non-magnetic, which the maker notes means strong oxidation and corrosion resistance — and owners confirm the heat plates are thicker than the original rusted steel. The compatibility list extends to 720-0783E, 720-0830A, 720-0864, and a dozen more Nexgrill codes, plus the 720-0898 line.
Durability gets mixed reviews here — some owners say the parts should last years, while a few report burner tubes breaking apart over time. The other quirk: the igniter wires run long, so you may need to wrap them around components to keep them tidy. At 1.6 pounds, the material feels dense and heavy-duty, which backs up the quality impression.
The complete package: burners, heat plates, and screws in one order — the hardware inclusion is the detail that saves you a second trip.
The honest caveat: longevity reports vary, so treat this as a strong refresh rather than a guaranteed decade of service.
Best for: Nexgrill 4-burner owners who want everything needed for a full fire-system swap in one box.
Not ideal for: anyone who dislikes routing long igniter wires — plan for a little cable management.
7. Charbroil TRU-Infrared Replacement Grate & Emitter
The specialized infrared grate that revives a 2015-or-older Charbroil’s even heat.
Charbroil’s TRU-Infrared system is different from standard grills — it uses an emitter plate to radiate heat evenly and cut flare-ups, and when the grate and emitter wear out, you can’t swap in a generic part. This genuine replacement measures 6″W x 17″D, and the math is straightforward: buy 3 sections for a 2-burner grill, 4 for a 3-burner, or 5 for a 4-burner. Owners confirm the fit on models like the 3-burner 463367016, where 4 pieces match the span perfectly.
The porcelain-coated finish is what keeps food from sticking and makes cleanup easy — owners note these are lighter than the original heavy grates yet well-made. The compatibility is specific: this fits Char-Broil Commercial, Signature, and Professional Series TRU-Infrared grills from 2015 and older. Check the last two digits of your grill’s model number on the back panel to confirm your year.
The honest sizing note: some owners mention the sections are narrower than the originals, leaving a slightly different coverage across the firebox. It’s a genuine OEM part (model 3297527R04), which is why owners say it brings rusted grills back to life for years. This is premium-priced per section, so a 4-burner setup adds up — but it’s still far cheaper than replacing the whole grill.
Purpose-built: only the TRU-Infrared emitter and grate combo keeps the flare-up-free, even-heat cooking this system is known for.
Before you order: verify your grill series and model year — this does not fit Char-Broil Performance Series TRU-Infrared grills.
For owners of: pre-2015 Char-Broil Commercial, Signature, or Professional TRU-Infrared grills that need a genuine replacement.
skip it if: you have a Performance Series grill or a newer model — this part won’t match.
8. Parts DC104 Cast Iron Grill Grates
Porcelain-coated cast iron grates that hold heat and leave proper sear marks.
When your cooking grates rust through, food sticks and sear marks disappear. These cast iron grates, each 17″ x 13 1/4″ (17″ x 26 1/2″ combined), come with a polished porcelain coating—that coating gives you the non-stick surface, while the cast iron underneath retains heat for real searing. Owners say they fit great and look exactly like the originals, with some reporting the grates holding up well for 4-6 years.
Quality is the most-mentioned aspect at 91 callouts, with fit trailing close behind at 86 — the two highest praise counts in this entire guide. The compatibility stretches across Nexgrill 4-burner 720-0830H and 5-burner 720-0888, Charbroil 4-burner 463241113, Kenmore, Uniflame, and Expert Grill models. The original part numbers (341-025, 549-057) match a wide swath of Home Depot grills.
The known trade-off is fragility — cast iron can crack during shipping, and the listing itself warns about it, promising a solution if it happens. Some owners also note the porcelain coating can flake over time, and one found the width off by about 1/4 inch (still functional). At 5.29 kg (about 11.7 pounds) per set, these are heavy in the hand, which is exactly what you want for heat retention. The rated max temperature is 500°C, so they’ll handle any sear you throw at them.
The grilling upgrade
- Cast iron core holds heat for even, professional searing
- Porcelain coating resists sticking and cleans up easily
- Huge compatibility across Nexgrill, Charbroil, and Kenmore
Handle with care
- Cast iron can crack in shipping — inspect on arrival
- Porcelain coating may flake after years of heavy use
Choose these if: you want the heat-retention and sear quality of cast iron with the easy-clean benefit of porcelain coating.
Proceed with: a careful unboxing — the material is genuinely fragile despite its heavy-duty cooking performance.
9. JCLMER 17 Inch Cast Iron Grill Grates
Matte cast iron grates that deliver restaurant-style sear marks on a Nexgrill.
If your priority is a proper crust on a steak, matte cast iron is the classic choice — it retains heat superbly and transfers it directly to the meat for those prominent sear marks. These measure the same 17″ x 13 1/4″ each as the DC104 set, and they’re built from heavy-duty cast iron that owners say holds up better than stainless steel alternatives. The fit is the top-praised aspect at 71 callouts, with quality second at 51.
The compatibility list is the longest of any grate here: Nexgrill 4-burner 720-0830H through 5-burner 720-0888N, plus Charbroil 463241113, Expert Grill 720-0789H, Kenmore, Uniflame, Uberhaus, and Members Mark models. Owners with Walmart 4-burner models confirm these fit well and make old grills look new again — one praised them as “heavy cast iron grates easy to clean, easy to put right back in place.”
The honest caveat is the gaps: a few customers note the grates leave gaps on either side of the firebox, which is a minor fit quirk on certain models. Maintenance is the real commitment with uncoated cast iron — the listing recommends leaving cooking oil on the grates after each use and drying them immediately after any soap-and-water cleaning to prevent oxidation. At roughly the same weight class as the DC104 set, these feel every bit as substantial.
The sear machine: matte cast iron’s heat retention is what creates the crusty, dark sear marks that coated grates struggle to match.
The maintenance cost: expect to oil these after every cook — skipping that step invites rust.
Best for: grillers who prioritize sear quality and don’t mind a quick oiling routine after each cook.
Consider alternatives if: you want set-and-forget grates — the porcelain-coated DC104 set needs less upkeep.
Understanding the Specs
Material: Stainless vs. Porcelain vs. Cast Iron
Each part wears a different material for a reason. Burner tubes are stainless steel because they live directly in the flame and need to resist rust and heat corrosion. Heat plates are usually porcelain-coated steel — the porcelain spreads heat evenly and blocks flare-ups before they reach your food. Cooking grates are often cast iron because it holds heat and leaves proper sear marks, though it needs more care to stay rust-free.
Dimensions and Gauge
Length and width are the make-or-break numbers for any replacement part. A burner listed at 14 7/8″ won’t sit right in a firebox built for a 15 7/8″ tube. Gauge (like 20GA) refers to steel thickness — lower numbers mean thicker, more durable metal. Always measure your old part before ordering, and match the model number code on the back of your grill against the listing’s compatibility list.
