When your grill’s burner starts sputtering or the grates are more rust than metal, the fix is usually a part swap, not a new grill. The real question is which replacement actually fits your exact model and which material handles years of heat without flaking. This guide cuts through the part-number chaos to the nine most reliable upgrades for common Charbroil, Nexgrill, Dyna-Glo, and Weber grills.
I’m Min — the founder and writer behind Gadgets Feed. 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.
We matched every part to its precise model list and weighed the durability evidence, so you can confidently buy the right bbq grill parts the first time without a return trip.
Our Picks at a Glance
How To Choose The Best BBQ Grill Parts
The single most common mistake is ordering by grill brand alone. Two grills from the same brand can use completely different burner lengths or grate widths, so the model number printed on your grill’s lid or frame is the key that open up the right part.
Measure Before You Order
Grill parts are precision-fit, but listings often cover dozens of models with one size. Pull out your old burner or grate and measure it with a tape measure, then compare against the exact dimensions in the listing — like 13 3/4″ x 2 1/4″ for a burner or 17″ x 13 1/4″ for a grate. The manufacturers themselves urge you to check, because a part that’s close but not exact can still leave hot spots.
Cast Iron vs. Stainless Steel
Cast iron grates hold heat superbly for professional sear marks, but demand oiling after each cook to prevent rust. Stainless steel burners resist corrosion well and handle high heat, making them a lower-maintenance pick for the flame tubes themselves.

In‑Depth Reviews
1. Parts DB106 Cast Iron Burners
Our pick — over 4.5★ from 800+ verified ratings; the strongest balance of quality and price.
The burner set that brings a 19-year-old grill back to even-flame life.
This 3-pack of cast iron burners is the crowd favorite for a reason — the fit is what wins people over, with owners reporting a perfect drop-in match on Charbroil, Centro, Thermos, and Costco Kirkland grills with no modification. The 8.31-pound package of three burners, each measuring 13 3/4″ x 2 1/4″, replaces original part numbers like 80000349 and 80018594 across a staggering list of Charbroil models including 463240804 and 463261406.
The defining story here is resurrection: “Fits perfectly, easy install, durable, even flames, great value; revived 19-year-old grill.” That sums up what buyers report consistently — the burners light smoothly, spread heat evenly, and kill the annoying hot spots and rusted-out sections that plague aging grills. Installation is genuinely tool-light, and the cast iron gives you that solid, heavy feel under the flame.
The honest caveat is durability, which gets mixed feedback — some say these outlast the originals, while a few report failures within a couple of months. The flame consistency also runs slightly less hot than factory parts for some users, and one owner found the air/fuel adjustment bolt ineffective at fine-tuning.
Why owners love it
- Perfect fit across many Charbroil, Centro, Therm
- Even flames that eliminate hot spots on old grills
- Easy install with no special tools required
os, and Kirkland models — no mods needed
The trade-offs
- Durability reports vary — a few units failed within months
- Flames can run less hot than original burners
- Adjustment screw may not fine-tune the flame
Reach for these if: you want to breathe years of new life into a Charbroil or compatible grill without buying new.
Think twice if: you need a guaranteed decade of heavy daily service — the longevity track record here is mixed.
2. Unicook Grill Burner Covers
Six porcelain steel heat tents that tame flare-ups for a song.
When your heat plates have burned through and grease drips are causing constant flare-ups, this 6-pack of flame tamers is the low-cost refresh. Each heat shield measures 14.6″L x 4.2″W in 20GA porcelain-coated steel, and the fit is what owners praise most — they drop in cleanly on Nexgrill models from the 2-burner 720-0864 up to the 6-burner 720-0898.
Owners mention “a good replacement for our barbecue,” noting these are actually more durable than the original factory vents and help extend the grill’s life. The heavy-duty porcelain coating is built to distribute heat evenly and shield your burners from drips, and the smooth surface wipes clean with a towel and degreaser. At 4.16 pounds for the full set, it’s also the lightest option here — a sign of the thin but effective steel.
One owner sums up the value case: “So much cheaper than purchasing a new grill and these grill plates make ours look almost new.” The slight knock against them is fit precision — one buyer found them “not a perfect fit but works well enough,” so measure your originals against the 14.6″ length before ordering.
Smart budget buy: This is the cheapest way to fix flare-ups and protect your burners, installing in minutes with zero tools. The trade-off is a slightly forgiving fit on some grills — measure first, then enjoy the savings.
3. Stainless Steel Burner & Heat Plate Kit
The complete burner-plus-tent refresh for a 4-burner Nexgrill.
This is the one-stop kit when both your burner tubes and heat tents are shot — it bundles 4 stainless steel burner tubes at 14 7/8″ x 1″ with 4 matching heat tents at 14 9/16″ x 4 3/16″. The stainless construction is rust-proof, anti-corrosion, and heat-resistant, which is the key advantage over the cast iron burners above if you live in a wet climate.
At 3.63 pounds, this kit is dramatically lighter than the 8.31-pound cast iron set — but that’s a feature, not a flaw, since stainless resists corrosion without the heft. Customers note it fits older 4-burner Nexgrills and “got it working again,” with the main praise landing on easy installation and a price that beats buying factory parts.
The recurring gripes are real: this kit ships without attachment clips or screws, so you may need to improvise — one owner used paperclips — and there are reports of rusted distributors over time. The ceramic spark module on some grills won’t attach to these tubes either, so check your igniter compatibility before ordering.
Best for full restorations: If your burners and heat tents both need replacing, this bundle is the practical move. The catch is missing hardware — set aside a few spare clips or screws before you start.
4. Parts DC104 Porcelain Cast Iron Grates
The porcelain-coated grates that make post-cook cleanup a wipe-down.
These 17″ x 13 1/4″ cast iron grates come with a polished porcelain coating — the feature owners rave about most after fit. The glass-smooth surface means food releases easily and cleaning is genuinely easy, which is the biggest daily-win for anyone tired of scrubbing bare cast iron. The 2-pack covers a 4-burner Nexgrill 720-0830H or a 5-burner 720-0888 with room to spare.
As a replacement set, reviewers point out these are better than the original factory grates — one owner called them “best of 3 replacement sets,” noting prior sets were rough, flaked, and rusted while these stay smooth. The porcelain coating handles the 500°C max temperature rating without issue, and the grates fit cleanly across Nexgrill, Charbroil, and Kenmore models.
The durability feedback is mixed, though — some shoppers say the porcelain flakes off over time, and the cast iron itself is fragile enough that the listing warns about breakage during shipping. At 5.29 kg for the pair, these are hefty, solid-feeling grates that sit flat and sear well.
What stands out
- Porcelain coating makes cleaning noticeably eas
- Heavier and sturdier than many original grates
- Fits Nexgrill, Charbroil, and Kenmore models
ier
Handle with care
- Porcelain can flake off with heavy use over time
- Cast iron is fragile in transit — a few arrive chipped
Choose these for: the low-maintenance cook who values easy cleanup over raw metal feel.
Look elsewhere if: you grill hard daily and need maximum coating longevity — flaking is the known risk.
5. JCLMER Matte Cast Iron Grates
Heavy matte cast iron built to lay down restaurant-grade sear marks.
If your priority is a serious sear on steaks, these 17″ x 13 1/4″ matte cast iron grates are built for exactly that. The heavy-duty construction distributes heat evenly and retains it superbly for prominent, professional sear marks. Owners describe it as “a serious heavy duty upgrade from the standard stainless set,” with the cast iron weight doing the work.
The fit is the headline though — buyers report these drop in perfectly on Nexgrill 720-0830H and 720-0888N models with no wobble, and they work across Charbroil and Expert grills too. The 2-pack covers the full cooking surface, and the maintenance routine is straightforward: wipe on a coat of cooking oil after each use to protect the iron from moisture.
The one recurring knock is sizing — a few owners find them “a bit small for their grills,” so measure your original against the 17″ width first. Cleanup is also harder than porcelain-coated grates, which is the honest trade-off for the sear performance. Overall durability gets strong praise, with owners calling them heavy-duty enough to last years.
The sear-first choice: This is the upgrade for anyone who wants steakhouse results at home. The price for that performance is a stricter oil-and-care routine — skip it if you want zero-maintenance cleanup.
6. Hisencn 21″ Cast Iron Grates
Direct-fit cast iron that brings a tired Dyna-Glo 2-burner back to life.
For Dyna-Glo DGF350CSP and DGH353CRP owners, these are the direct replacements that work like the originals. Each grate measures 15.5″ x 10.5″, with the pair forming a 15.5″ x 21″ total cooking surface — and the fit is the top praise, with buyers reporting a perfect match for their 2-burner gas grills. They also drop into several Blue Rhino and Backyard models.
The cast iron construction retains and spreads heat evenly for beautiful sear marks and better flavor. Owners call the quality “just as good as name brand at 60% of the cost” — a strong value read for anyone who wants factory-level performance without the factory price tag. Installation is a straightforward drop-in with no tools.
The honest split in the reviews is durability and size: some owners mention rust forming within two months, while others say they’re holding up great, and a few find them a couple of inches too small for their specific grill. The brand’s own care guide is thorough — coat with oil before and after use, and heavily grease if storing long-term.
A solid economy pick: For the Dyna-Glo owner wanting factory-fit grates at a discount, this delivers. The caveat is variable longevity — rust-resistance depends heavily on your oiling routine.
7. Dyna-Glo DGF510SBP Grates
Three enamel-coated slabs of iron that make a 5-burner Dyna-Glo look new again.
These are the heaviest grates in this lineup at 13.37 pounds — and that weight is the point. The upgraded matte enamel cast iron resists rust, chipping, and cracking, and the 3-pack of grates (each 16 1/4″ x 9 7/8″, 29 5/8″ total) covers a 5-burner Dyna-Glo DGF510SBP or DGF510SSP completely. Customers note these are “way heavy duty and better than my original grate,” with a fit that slots right in.
The appearance is a big part of the appeal — reviewers point out the grates make their grills look new again, and the smooth enamel surface makes cleanup genuinely easy. The heat retention and even cooking get consistent praise, and the construction shows no loose spot welds even after heavy use. As direct replacements, they’re described as identical to the original equipment.
There’s very little negative feedback in the data — the main note is that these are fairly heavy, which is expected for cast iron, and owners recommend oiling before first use for a non-stick surface. If you own a Dyna-Glo 5-burner or a compatible Backyard or BHG model, this is about as close to a sure thing as grill parts get.
The upgrade that shows: Heavy, handsome, and easy to clean — this is the premium refresh for a 5-burner Dyna-Glo. The only consideration is the weight when lifting them for cleaning.
8. GasSaf Weber Spirit Grates
The cast iron grates that dragged a 2003 Weber gas grill back from the brink.
If you own a Weber Spirit 300 series or a Genesis 1000-3500, these 17.5″ x 11.9″ cast iron grates are engineered for your exact model — and the stories in the reviews are remarkable. One owner describes a Weber Spirit 700 that “has held up great for almost 30 years” getting a new lease on life with grates that fit perfectly and feel “so much more durable” than the originals. Another brought a 2003 Weber back to full function.
The fit is the single biggest praise point, with the 2-pack slotted into Weber models 7638 and 7639, plus a huge list of Genesis Gold, Silver, and Platinum configurations from 2000-2010. The cast iron retains heat superbly, distributes it evenly, and resists the deterioration that wears out factory steel grates. Shoppers say these perform as well as — and often better than — the original equipment.
The rare negative is a brittle edge: one unit arrived with a small piece broken off the edge, which didn’t affect the main grilling area. Overall, the durability verdict is strong — with proper care, these hold up far better than the OEM steel grates they replace.
Why Weber owners switch
- Direct fit for Spirit 300 and Genesis 1000-3500
- Cast iron outlasts the factory steel grates
- Even heat distribution for consistent results
Watch out for
- Cast iron edges can chip in transit
- Needs regular oiling to prevent rust
Best for: the Weber owner with a solid frame and worn-out grates who wants factory-level performance back.
Not for: anyone who won’t commit to oiling cast iron after each cook — that routine is the price of durability.
9. BBQration Tru Infrared Grates
Three hefty grates built to match Charbroil Tru Infrared burner spacing exactly.
This 3-pack of matte cast iron grates (17″ x 9 1/2″ each, 17″ x 28 1/2″ total) is the specialized fix for Charbroil Tru Infrared 4-burner grills, with the fit earning the loudest praise in the reviews. Buyers report these drop in perfectly on the 463255020 and 463242715 models, and one even used them to restore a Sabre grill “to brand new performance.” The 17.96-pound package signals the serious heft you’re getting.
The construction quality gets consistent positive marks — “the quality is evident in its well-crafted construction” — and the grates feel as heavy and solid as the originals. They work well with a grill scraper too: the V-shapes clean burner debris while the circles clean rails and the warming rack. As a replacement for the G541-0016-W2 and G533-0009-W1 part numbers, these are purpose-built for the Tru Infrared emitter system.
The durability verdict is honestly mixed — some owners find them sturdy for the long haul, while others report the matte cast iron “becomes brittle after only a few uses.” There’s also a fit note for mixing brands: the emitter holes may not align if you pair these with non-Charbroil emitters, so keep the same brand across the system.
Purpose-built for Tru Infrared: If your Charbroil Tru Infrared grates are worn out, this 3-pack is the correct match. The caveat is brittleness in some units and the need to pair with matching emitters.
Understanding the Specs
Material Matters
Cast iron holds heat superbly and sears well, but requires oiling to prevent rust. Porcelain-coated cast iron adds an easy-clean surface that resists food sticking, though the coating can flake with heavy use. Stainless steel resists corrosion best of all, making it ideal for burners in humid climates.
Dimensions Drive Fit
Burner length and grate width are the two numbers that decide whether a part fits. A 13 3/4″ burner won’t work in a 15″ slot, and a 17″ grate can overhang a smaller grill. Always measure your original part against the listing dimensions — the manufacturers themselves say to check before ordering.
