The best Weber Smokey Mountain 18 grates depend on which position needs replacing. The Weber 17.5-inch cooking grate is the direct pick for a worn upper grate, while a three-piece set replaces the upper, lower and charcoal grates together.
Measure the grate you're replacing and note its position: upper food grate, lower food grate or charcoal support. The words “18-inch grate” alone don't identify which part will fit.

How we chose Weber Smokey Mountain 18 grates
The useful differences are fit, position, dimensions and whether a package replaces one grate or several. We compared those details and gave priority to parts whose stated use matches the 18-inch Smokey Mountain.
A part that fits another Weber grill may still be the wrong choice for a Smokey Mountain. The kettle and Smokey Joe options below are included to make those limits clear, so you can avoid choosing by diameter alone.

Best Weber Smokey Mountain 18 grates for each replacement need
Choose a single replacement when one grate is worn and the others remain sound. Choose a three-piece kit when you need to refresh both cooking levels and the charcoal support.
Weber® Charcoal Cooking Grate for 18" Grills: Best for upper grate repairs
- Fits 18-inch charcoal grills
- 17.5-inch grate
- Fits 18-inch Smokey Mountain upper cooking position
- Nickel-plated steel
A single 17.5-inch Weber grate fits the upper cooking position on an 18-inch Smokey Mountain. It is not for the lower charcoal grate.
Pros
- Weber part for the upper cooking position
- Single grate replacement
- Easy to use and replace
Cons
- Does not replace lower cooking or charcoal grates
The Weber® Charcoal Cooking Grate for 18" Grills is the clearest match for an upper cooking grate replacement. It measures 17.5 inches and is specified for the upper cooking position on an 18-inch Smokey Mountain Cooker.
Buy this single grate if your lower cooking grate and charcoal grate remain usable. Its nickel-plated steel construction and stated upper-position fit make the choice straightforward for a one-part repair.
The position limit matters: this grate is not for lower charcoal grate use. If several parts are bent or worn through, a complete set may make more sense than replacing them one at a time.
A grate supports food directly, while extra racks create another way to arrange it. Our guide to best replacement smoker racks can help if your real need is more cooking organization.
Uniflasy Upper: Best for full grate refreshes
- Includes upper, lower and charcoal grates
- 17.5-inch upper grate
- 17-inch lower grate
- 15.25-inch charcoal grate
This set covers the upper and lower cooking positions plus the charcoal grate. Compare its stated sizes and part numbers with your original parts.
Pros
- Three replacement parts in one set
- Raised handles on cooking grates
- Matches Weber 7432, 85042 and 63013 part numbers
Cons
- More parts than needed if only one grate is worn
Uniflasy is a practical choice when all three grate positions need attention. The set includes a 17.5-inch upper cooking grate, a 17-inch lower cooking grate and a 15.25-inch charcoal grate.
The upper and lower cooking grates have raised side handles for lifting them out. The plated-steel set is described as compatible with Weber 7432, 85042 and 63013 components, so those part numbers give you a second way to compare it with your current pieces.
Choose this kit if you want the three positions covered together. Skip it if only one grate is damaged and the others are still serviceable, since the extra pieces would go unused.
QuliMetal 3-Pack Grill Grate for Weber Smokey: Best for three-part replacements
- Includes upper, lower and charcoal grates
- 17.5-inch upper grate
- 17-inch lower grate
- 15.25-inch charcoal grate
The three-piece set is designed for an 18-inch Smokey Mountain, with the same upper, lower and charcoal grate sizes as the listed Weber replacement part numbers.
Pros
- Replaces three grate positions
- Raised side handles on cooking grates
- Dimensions and part numbers are stated
Cons
- A full set may be unnecessary for a single worn grate
QuliMetal is another full-set option for an 18-inch Smokey Mountain. Its stated dimensions are 17.5 inches for the upper cooking grate, 17 inches for the lower grate and 15.25 inches for the charcoal grate.
Raised side handles are included on the upper and lower cooking grates. The set names Weber 7432, 85042 and 63013 as the matching part numbers, which helps when you are checking replacements for a smoker that has not been modified.
Consider it when you need all three pieces and have verified the measurements. If you're replacing just an upper cooking grate, the single Weber part is the simpler fit for that job.
Weber® Hinged Charcoal Cooking Grate for 18": Best for kettle coal access
- 17.5-inch grate
- Flip-up sides
- Heavy plated steel
- Designed for 18.5-inch Weber kettles
Its hinged sides help add briquettes to a compatible kettle. The stated fit is for 18.5-inch Weber kettle grills, so confirm fit before using it as a Smokey Mountain replacement.
Pros
- Flip-up sides for adding briquettes
- Curved hand grips
- 17.5-inch grate
Cons
- Designed for kettle grills, not specifically the Smokey Mountain
This hinged Weber grate is designed for 18.5-inch Weber kettle grills. Its flip-up sides let you add briquettes to a kettle without lifting the whole grate, and its 17.5-inch diameter may look similar to the Smokey Mountain upper grate.
The stated fit is for kettle grills, though, so don't assume that a similar diameter makes it a Smokey Mountain replacement. Choose it for a compatible kettle when coal access through hinged sides is useful; skip it for an 18-inch Smokey Mountain unless you confirm the fit and position first.
For kettle cooking, you can also compare it with a Weber grill pan if you need a surface for smaller foods. The pan is a cooking accessory, while this grate supports food and opens to reach briquettes.
Weber® Charcoal Cooking Grate for 14" Grills: Best for Smokey Joe owners
- 13.5-inch grate
- Fits 14-inch Smokey Joe grills
- Plated steel
- No assembly required
This Weber grate is for 14-inch Smokey Joe models, not the 18-inch Smokey Mountain cooking grate. Its smaller size makes it a poor fit for the target smoker.
Pros
- Weber replacement for specified Smokey Joe models
- Stated 13.5-inch diameter
Cons
- Too small for an 18-inch Smokey Mountain
The Weber 14-inch cooking grate is for Smokey Joe Silver and Gold, Smokey Joe and Tuck-N-Carry grills. At 13.5 inches across, it is too small for the upper grate position in an 18-inch Smokey Mountain.
It suits a reader who needs a replacement for one of those portable grills. Skip it for the Smokey Mountain, even if the shared Weber name makes it seem like a close match.
Hisencn Grates for Weber 18-inch Smokey Mountain: Best for alternate full sets
- Includes three grates
- 17.5-inch upper cooking grate
- 17-inch lower grate
- 15.25-inch charcoal grate
This set includes upper, lower and charcoal grates sized for the corresponding Weber part numbers. Check your original grate dimensions before ordering.
Pros
- Three grate positions covered
- Stated dimensions for each grate
- Raised side handles
Cons
- A full set is unnecessary if only one grate needs replacing
Hisencn offers a three-piece alternative for an 18-inch Smokey Mountain. The set includes a 17.5-inch upper cooking grate, a 17-inch lower grate and a 15.25-inch charcoal grate.
The listed matching numbers are Weber 7432, 85042 and 63013. The cooking grates have raised side handles, and the material is plated steel.
This set is suited to a full refresh when each position needs replacement. If only one part is damaged, compare a single position-specific grate instead, and don't buy the set until the three measurements match the parts in your cooker.
DcYourHome 17.5" Round Grate Kit for Weber: Best for two-grate swaps
- Includes a 17.5-inch cooking grate
- Includes a 13.5-inch charcoal grate
- Fits several 18.5-inch Weber grill models
The kit pairs a cooking grate with a charcoal grate for several 18.5-inch Weber grills. Confirm the smoker model and the charcoal grate size before choosing it.
Pros
- Includes cooking and charcoal grates
- 17.5-inch cooking grate
- Names Smokey Mountain among compatible series
Cons
- Charcoal grate size differs from the 15.25-inch size in three-piece sets
DcYourHome pairs a 17.5-inch cooking grate with a 13.5-inch charcoal grate. Its stated compatibility includes the Smokey Mountain Cooker series, but that charcoal-grate measurement differs from the 15.25-inch part included in the three-piece sets.
That difference is central to the buying decision. Consider this kit only if both the cooker fit and the 13.5-inch charcoal grate size match your needs; skip it if you expect the common 15.25-inch charcoal support.
Weber # 80624 Lower Cooking Grate: Best for lower cooking repairs
- Weber lower cooking grate
- For 18-1/2-inch Smokey Mountain Cooker
This Weber part is identified as a lower cooking grate for the 18-1/2-inch Smokey Mountain Cooker. Check that your smoker uses this part number before ordering.
Pros
- Weber part for the lower cooking position
- Identified for the Smokey Mountain Cooker
Cons
- Does not replace the upper cooking grate or charcoal grate
Weber identifies part 80624 as a lower cooking grate for the 18-1/2-inch Smokey Mountain Cooker. This makes it the position-specific option when the lower food grate needs replacement and the upper grate is still fine.
The stated details don't give a diameter, so check the 80624 part number against your smoker before ordering. This part replaces the lower cooking surface, not the upper grate or the grate that supports charcoal.
Dinlon 13.5" Charcoal Cooking Grate Fit: Best for small charcoal supports
- 13.5-inch grate
- Stainless steel
- Fits specified 18.5-inch Weber charcoal grills and 14-inch Smokey Joe models
This 13.5-inch grate is described for charcoal support on several Weber grills and as a cooking grate for 14-inch Smokey Joe models. It is not an 18-inch Smokey Mountain upper grate.
Pros
- Stated 13.5-inch size
- Stainless steel construction
- Can suit a specified charcoal-grate use
Cons
- Not sized for the Smokey Mountain upper cooking grate
Dinlon's 13.5-inch stainless steel grate is described for charcoal support on several Weber grills and as a cooking grate for 14-inch Smokey Joe models. It is not sized for the 18-inch Smokey Mountain upper cooking grate.
This option makes sense only when your required position and existing part measure 13.5 inches. Skip it if you need a standard upper grate or a three-piece Smokey Mountain set.
A grill basket for BBQ can keep smaller foods together while they cook. It sits on a cooking grate and helps with food handling, but it cannot replace a damaged grate or charcoal support.
Which grate position do you need for your Smokey Mountain?
Identify the position before comparing brands: the upper cooking grate, lower cooking grate and charcoal grate each do a different job. In the replacement options here, the upper grate is 17.5 inches, the lower cooking grate is 17 inches and several full sets use a 15.25-inch charcoal grate.
The charcoal grate supports fuel below the food grates. The cooking grates hold food at one or two levels, so buying a charcoal grate when you need a food surface can leave you with a part that doesn't solve the problem.
If your cooker uses both food levels, think about what you'll cook and how much access you'll need to the lower surface. A rib rack can make better use of available grate space for ribs, but it doesn't change which grate size your smoker requires.
How do you check fit before buying a replacement grate?
Check three things: smoker model, grate position and the old part's diameter or part number. Compare those details with the replacement's stated measurements and compatible part numbers before you order.
Measure across the widest point of the old grate, from outside edge to outside edge. If it has a part number, use that as another identifier, especially when the replacement is described for multiple Weber grill models.
Don't choose based on “18-inch” in a product name alone. The Weber kettle grate has a similar diameter to the upper Smokey Mountain grate, but its specified use is for kettle grills.
The 14-inch Weber grate is for Smokey Joe models. A charcoal grate is also not interchangeable with a food grate just because both are round.
If the smoker has had parts replaced before, measure the actual grate you have rather than relying only on the original configuration. When a specific position or size isn't clear, confirm the part number and fit with the seller before you buy.
Should you buy one grate or a complete set?
Buy one grate when one part needs replacement and the rest remain usable. Weber's 17.5-inch part addresses the upper cooking position, while part 80624 is identified for the lower cooking position on an 18.5-inch Smokey Mountain Cooker.
Choose Uniflasy, QuliMetal or Hisencn when you need all three positions refreshed. Each set states dimensions for the upper, lower and charcoal grates, so compare each one with the pieces in your cooker rather than treating the kit as a generic three-part fit.
A complete kit can save you from sourcing multiple pieces separately, but it includes parts you may not need. If the charcoal grate is still flat and supports fuel properly, replacing it only because the upper grate is worn adds an unnecessary part to your repair.
The DcYourHome kit covers two positions, but its charcoal grate is 13.5 inches. That makes it a different choice from the three-piece kits with a 15.25-inch charcoal grate, so confirm the size carefully.
How should you set up and care for replacement grates?
Let the smoker cool before removing or installing grates. Set each replacement into the position it is meant to occupy, and check that it sits evenly without rocking before adding fuel or food.
For a multi-piece set, sort the parts by diameter and position before assembly. The largest is the upper cooking grate, the next is the lower cooking grate and the smallest is the charcoal grate in the common three-piece sets described here.
After cooking, let the smoker cool enough to handle safely, then remove loose food and grease. Use a cleaning method suited to the grate material and follow the smoker's care instructions; avoid forcing a part that does not lift freely.
Check the bars and contact points during routine cleaning. A grate that rocks, has badly damaged bars or no longer supports food or charcoal securely deserves a closer fit check or replacement.
For a detailed cleaning routine, follow our guide to deep cleaning smoker grates.
Don't confuse cleaning with repair. A brush can remove residue, but it won't correct a bent grate or turn a cooking grate into the right charcoal support.
What mistakes should you avoid when buying Smokey Mountain grates?
The most common mistake is choosing a round grate by diameter without checking its position and intended grill. A 17.5-inch kettle grate, a 13.5-inch Smokey Joe grate and a Smokey Mountain upper grate may look related, but their specified uses differ.
Another mistake is ordering a full kit to solve a single-part problem. First inspect each level, then replace only the damaged piece unless the other grates are also worn or you specifically want a full set.
Don't treat the lower food grate and charcoal grate as the same component. The lower food grate holds food, while the charcoal grate supports fuel below the cooking surfaces.
Finally, don't assume all three-piece sets have identical dimensions. Compare each stated measurement, especially the charcoal grate, before relying on a set's broad compatibility description.
Which Weber Smokey Mountain 18 grates should you choose?
Choose the Weber 17.5-inch grate for a straightforward upper-grate repair. Pick Uniflasy, QuliMetal or Hisencn when all three grate positions need replacement and their measurements match your smoker.
For a lower food grate, check whether Weber part 80624 matches your cooker. Treat the hinged kettle grate, the 14-inch Smokey Joe grate, and the smaller charcoal-grate options as specialized choices that need a careful position and size match.
Start with the old part's position and measurement, then select the best Weber Smokey Mountain 18 grates for that exact job. If your next question is how to arrange ribs on the new surface, see our [rib rack setup guide] for setup ideas.

Frequently asked questions
What size grate fits an 18-inch Weber Smokey Mountain?
The upper cooking grate is 17.5 inches across, while common replacement sets identify the lower cooking grate as 17 inches and the charcoal grate as 15.25 inches.
Check your smoker's model and the position of the part you are replacing. Grate sizes differ by position.
Can I use a Weber kettle grate in a Smokey Mountain?
Some 17.5-inch Weber cooking grates are specified for both 18-inch Smokey Mountain cookers and 18.5-inch kettle grills. Check the exact part and intended position, since a kettle charcoal grate is not the same as a Smokey Mountain lower cooking grate.
Should I replace all the grates at once?
Replace only the grate that needs it unless the others are also worn or damaged. A three-piece set can make sense when the upper, lower and charcoal grates all need replacement, but it adds parts if one grate is still usable.
How do I clean Smokey Mountain grates before replacing them?
Let the smoker cool, remove loose food and grease, then clean the grates using a method suited to their material. Our guide to deep cleaning smoker grates covers the steps and care points.
Can I use a rib rack with replacement grates?
A rib rack can help arrange ribs vertically when the cooking grate has enough room and the rack sits steadily. Check your grate space and food placement before cooking, then follow our guide to using a rib rack for setup ideas.
