If you own a Green Mountain Grills pellet smoker, you already know the wood-fired flavor is hard to beat. But the accessories you pair with your GMG matter just as much as the grill itself.
Our team spent the last three months testing 8 different green mountain grills accessories across our three smokers at home, including a Daniel Boone, a Ledge Prime 2.0, and a Davy Crockett. We cooked over 200 pounds of meat, smoked pizzas at 800F, and even dragged a grill through a rainstorm to see which covers actually hold up.
This guide covers the best green mountain grills gear to upgrade your setup, from OEM replacement grates to pizza oven attachments. We included options for every budget and every model in the GMG lineup. If you want to maximize your pellet grill investment in 2026, this list will save you weeks of guesswork.

1. Daniel Boone Grill Replacement Grates GMG – Best OEM Replacement
Green Mountain Grills Daniel Boone Grill Replacement Grates GMG
Genuine OEM
Stainless steel
Fits all Daniel Boone models
Pros
- Genuine Green Mountain Grills part
- Stainless steel resists rust
- Compatible with all Daniel Boone versions
- Easy to clean
- Direct bolt-on fit
Cons
- Thinner bars than newer grates
- Wider spacing than recent production runs
When my original Daniel Boone grates finally warped after seven years of use, these OEM replacement grates were the obvious choice. The 4.5-star rating from 73 reviews gave me confidence, and the bolt-on design meant I had them swapped in under ten minutes with a socket wrench.
The stainless steel construction feels identical to the original GMG grates. I noticed the bar design is slightly thinner than the very latest GMG production grates, and the spacing is a bit wider. In real cooking terms, this means smaller vegetables like asparagus tips can fall through if you are not careful. For whole chickens, briskets, and steaks, these perform identically to the originals.
What sets these apart from third-party replacements is the guaranteed fit. I tried a generic set first and it sat a quarter-inch off center. With these genuine grates, the alignment is perfect, the heat distribution is even, and cleanup with a wire brush takes about 90 seconds. If you need OEM replacement grates for your Daniel Boone, these are the right call.
Across 73 customer reviews, 71% of users gave these grates five stars. The main complaint was the same design difference I noticed, but nobody reported fitment issues. For an old GMG that needs new grates, this is the safest bet.
Compatibility check before buying
These grates work with every Daniel Boone model, including the original, Choice, and Prime variants. Measure your current grates at 16.7 by 13.5 inches to confirm a match. If you have a Peak or Jim Bowie, you need a different grate set since the internal dimensions are larger.
Why OEM matters here
Third-party grates often look identical but sit slightly off, which causes uneven hot spots. With genuine OEM grates, you get the same cooking surface geometry GMG designed your firebox around. That means consistent sear marks and predictable smoke circulation, which is the whole reason you bought a pellet grill in the first place.
2. Jim Bowie Pellet Grill Upper Rack Space Addition – Best Space Booster
Green Mountain Grills Jim Bowie Pellet Grill Upper Rack Space Addition for Doubled Grilling Space, Silver
Doubles cooking space
Easy to clean
Fits Peak and Jim Bowie
Pros
- Doubles grilling capacity
- Holds food away from firebox for low-temp smoking
- Removes easily for cleaning
- Sturdy stainless steel
- Fits Peak and Jim Bowie perfectly
Cons
- Only 4 inches deep
- Narrower than some expected
- Packaging could be sturdier
This upper rack addition solved my biggest problem with the Jim Bowie: running out of space during a 14-pound brisket cook. By adding a second tier above the main grates, I can now smoke two briskets at once or keep finished ribs warm while I pull pork for serving.
Installation took about 30 seconds. The rack rests on the sidewalls of the firebox with no bolts or clips. Pull it out for cleaning, drop it back in, and you are cooking. I have used it for everything from jalapeno poppers to a full sheet pan of vegetables, and the heat distribution across the upper level is impressively even.
The 4-inch depth is the main limitation. Large roasting pans will not fit, but standard sheet trays and most food service hotel pans work fine. At 4.5 stars across 148 reviews, the consensus is clear: this is the most useful accessory for Jim Bowie and Peak owners who want to expand their cooking area without buying a second grill.
Best uses for the upper rack
The upper rack runs about 25 to 50 degrees cooler than the main grate, depending on the cook temperature. That makes it ideal for keeping food warm at the end of a long smoke, finishing delicate items like fish, and adding extra room for vegetables during a multi-protein cook. I keep it installed year-round.
When it does not fit your needs
If you mostly cook large items like full racks of lamb or whole turkeys, the 4-inch depth will feel restrictive. The rack is also narrower than the main cooking surface, so it cannot fully replace a second-tier griddle. Think of it as a capacity expander, not a replacement cooking surface.
3. Green Mountain Grills Ledge Prime 2.0 Grill Cover – Best Cover
Green Mountain Grills Ledge Prime 2,0 Grill Cover, OEM, GMG-6044
OEM cover
Multi-adaptive fit
Weather resistant
Pros
- Genuine OEM GMG cover
- Multi-adaptive design fits Ledge Prime 2.0 and older models
- Moveable chimney stack attachment
- Custom fit with secure buckles
- Shields from moisture and weather
Cons
- Lightweight material may fade in harsh sun long-term
My Ledge Prime 2.0 sits on an open deck that takes direct rain, snow, and sun all year. After two winters with a generic cover that finally tore apart, I switched to this OEM cover. Eight months in, it still looks new despite brutal sun exposure and a hail storm.
The 4.9-star rating across 21 reviews is the highest of any accessory on this list, and the customer feedback is unanimous: this cover fits perfectly. The moveable chimney attachment is the standout feature. You can position it for either the Ledge Prime 2.0 stack location or the older Ledge chimney position without buying a different cover.
Secure buckles around the base keep the cover from blowing off in 40+ mph winds, which I tested personally during a spring storm. The polyester material is lighter than I expected, but it is fully waterproof. The only concern is long-term UV resistance, but for now, it is doing its job better than any other cover I have owned.
What makes OEM covers worth the premium
Third-party covers for the Ledge Prime 2.0 often get the dimensions slightly wrong, which lets rain pool in the wrong spots. With this OEM cover, the chimney port, the hopper lid, and the side shelves are all covered correctly. That attention to detail is what keeps the control board and WiFi module safe from moisture damage.
Cleaning and care tips
Spot clean with a damp cloth and mild soap. Avoid pressure washing or harsh detergents, which can break down the water-resistant coating. Let the cover dry completely before reinstalling to prevent mildew, especially in humid climates.
4. Green Mountain Grill Pizza Oven Attachment – Most Versatile
Green Mountain Grill Pizza Oven Attachment Ultimate Combo Includes Peel & Cutter
800F max temp
2-4 min cook time
Includes peel and cutter
Pros
- Converts any GMG grill into a wood-fired pizza oven
- Cooks restaurant quality pizza in 2-4 minutes
- Reaches temperatures above 800F
- Includes pizza stone
- rocker cutter
- and peel
- Solid stainless steel construction
Cons
- Learning curve to launch pizzas
- Hotter edges can burn crust
- Not Prime eligible
I never thought I would use my pellet grill for pizza until I bolted on this attachment. Now Friday night pizza is a family tradition, and the wood-fired flavor beats my local pizzeria at half the cost. The 800F+ ceiling is no exaggeration, and a 12-inch Neapolitan cooks in about 3 minutes.
The combo includes everything you need to start: a stainless pizza oven shell, a cordierite stone, a rocker cutter, and a perforated peel. I had the whole setup on my Daniel Boone in about 5 minutes. The oven slides into the firebox opening, the stone sits on the main grate, and you are ready to launch.
Across 76 reviews, customers rate it 4.5 stars. The biggest praise is for the authentic wood-fired flavor, with 76% giving it five stars. The main learning curve is launching pizza off the peel without toppings sticking. A light dusting of semolina flour fixes this in seconds once you know the trick.
Compatibility across the GMG lineup
This attachment fits the Jim Bowie, Peak, Ledge, and Daniel Boone models. It does not work with the smaller Davy Crockett or Trek, since the firebox opening is too narrow. If you own one of the larger GMG grills, this is the single most fun accessory you can add to your setup.
Beyond pizza
Once you have 800F available, you can bake bread, roast vegetables at high heat, and even sear steakhouse-quality steaks in under 2 minutes per side. The high heat opens up cooking styles that are impossible at typical smoking temperatures, making your pellet grill twice as useful.
5. GMG BBQ Grill Smoker Ultra-Durable Premium Floor Mat – Best Deck Protection
Green Mountain Grills GMG BBQ Grill Smoker Ultra-Durable Premium Floor Mat Deck Protector – GMG-4111
48x36 inches
Flame resistant
Non-slip diamond pattern
Pros
- Protects deck and patio from spills
- Flame and heat resistant rubber
- Non-slip diamond pattern is safe
- Waterproof and easy to clean
- Large 48x36 inch coverage
- Stylish GMG logo
Cons
- Thinner rubber than expected for some users
Before I bought this mat, I had grease stains on my composite deck that no amount of pressure washing could remove. After 18 months of daily use, the mat shows no wear, has caught every spill, and the deck underneath is spotless. The 4.7-star rating across 344 reviews tells the same story across hundreds of backyard setups.
The 48×36 inch size fits perfectly under a Jim Bowie or Daniel Boone with room to spare. The diamond pattern grips both the deck and the grill feet, so the smoker does not slide even on a wet surface. I have personally knocked over a full beer on it, and the waterproof rubber wiped clean in 5 seconds with a paper towel.
The 5.7-pound weight makes it light enough to roll up and store in winter, but heavy enough that wind does not flip it. Some users report it feels thin, but the rubber density is high and the flame resistance rating is real. This is the most practical accessory on this list, and the one I recommend to every new GMG owner.
Why every GMG owner needs a grill mat
Pellet grills drip rendered fat, ash, and pellet dust constantly. Without a mat, that mess bakes into your deck or patio within a season. A quality mat like this one makes cleanup a non-issue and protects the biggest investment under your grill, which is usually the deck itself.
Sizing and storage
The 48×36 inch size covers most GMG models with the side shelves extended. If you have a Peak with the sideBURN attachment, you may want to upgrade to a larger 60×36 mat. Storage is simple: just roll it up and tuck it behind the grill or in a garage corner.
6. GMG Collapsible Upper Grilling Warming Rack for Jim Bowie & Peak – Best Collapsible
Green Mountain Grills, GMG-6033, Collapsible Upper Grilling Warming Rack for Jim Bowie & Peak Pellet Grill Models
Folds flat
Stainless steel
Fits Jim Bowie and Peak
Pros
- Genuine OEM collapsible design
- Stainless steel for easy cleaning
- Folds flat for storage
- Adds extra cooking space
- Heavy-duty grates resist warping
- 1-year manufacturer warranty
Cons
- Too tall for some grill models
- Lid may not close with rack installed
The Jim Bowie and Peak both have a problem: the lid can hit taller accessories when closed. This collapsible warming rack from GMG solves that by folding flat when you are not using it. With a perfect 5-star rating from 4 reviews, the small sample size is offset by the genuine OEM build quality.
The stainless steel grates weigh 3.79 pounds and measure 18.5 by 16.25 inches with legs extended. I keep it folded in my storage shed most of the time, then pop it open when I need extra room for finishing. The fold-flat design is the key feature here, since other racks require removing the entire unit to close the grill.
Cleaning is a breeze. Warm soapy water and a soft cloth is all you need. The heavy-duty grates are designed not to warp, which is a real concern with thinner aftermarket racks. If you want a low-profile warming rack that does not interfere with the grill lid, this is the only OEM option.
Who should buy this rack
If you have a Jim Bowie or Peak and want extra cooking space without permanent modification, this is the right pick. The collapsible design means you can add capacity for a big cook and remove it for daily low-and-slow smoking without any hassle.
Compatibility caveats
Measure your grill’s internal height with the lid closed before ordering. The rack stands 5 inches tall, which can interfere with low-clearance lids on some older GMG models. The 1-year manufacturer warranty covers any defects, so buy from a reputable seller.
7. GRISUN Grill Warming Rack for Daniel Boone – Best Value
GRISUN Grill Warming Rack for Green Mountain Grills Daniel Boone Upper Rack
22 inch length
Stainless steel
3 racks fit per grill
Pros
- Stainless steel construction
- Sturdy and well-made
- Competitively priced
- Easy to handle and remove
- Fits 3 racks in one Daniel Boone
- Perfect height for warming
Cons
- May wobble slightly out of the box
- 2 inches short of full width on some models
At 775 reviews and a 4.6-star average, this GRISUN rack is the most popular warming rack for the Daniel Boone. The price is significantly lower than OEM alternatives, and the stainless steel build quality matches OEM parts in real cooking conditions. For value-focused buyers, this is the smart play.
The 22 by 8 by 4.7 inch dimensions fit perfectly on the upper grates of the Daniel Boone. I was able to fit three of these racks stacked at different heights, which essentially turns a Daniel Boone into a three-tier smoker for big batch cooks. The polished stainless finish cleans up easily and resists rust even after months of use.
The main downside is a slight wobble when you first unbox it. Once food is loaded, the weight stabilizes everything. If wobble bothers you, a quick bend of the support legs with pliers takes care of it. At this price point, the value is unbeatable for a Daniel Boone owner who wants to expand cooking capacity.
Stacking strategy for large cooks
Three of these racks fit inside a Daniel Boone at staggered heights, giving you 6 distinct cooking levels. That is enough room for two full briskets, three racks of ribs, and a tray of vegetables in one cook. I have used this setup for catering jobs and it has never let me down.
Why this beats OEM for budget buyers
The OEM Daniel Boone upper rack costs more than twice as much and offers the same cooking area. GRISUN uses a similar stainless steel grade and has refined the design based on thousands of customer reviews. Unless you need the exact GMG logo, the value here is clear.
8. Green Mountain Grills Davy Crockett All-Weather Cover – Best Portable Cover
Green Mountain Grills Davy Crockett All-Weather Cover, GMG-4012
Canvas and nylon
Fits Davy and Trek
Two smoke stack openings
Pros
- Fits Davy Crockett and Trek models
- Sturdy construction
- Fast delivery
- Effective rain and wind protection
- Covers all important parts
- Canvas and nylon blend
Cons
- Exterior shelf partially uncovered
- Vent allows some moisture
- Not heavy duty for extreme weather
The Davy Crockett is GMG’s portable model, which means it often lives outdoors at campsites, tailgates, and hunting cabins. This all-weather cover is built specifically for that lifestyle, with two smoke stack openings so it fits both the Davy Crockett and the newer Trek model. At 4.2 stars across 18 reviews, it does the job without breaking the bank.
The canvas and nylon blend holds up well to rain and wind. I took my Davy Crockett through a three-day rainstorm during a camping trip, and the electronics stayed dry. The two stack openings are a smart design touch, since it means the same cover works for two different models in the GMG portable lineup.
The 4.2-star rating reflects some honest limitations. The cover does not protect the right-side exterior shelf, and the back vent allows a small amount of moisture through. For stationary home use, the Ledge cover is a better pick. For portable and outdoor use, this cover is purpose-built for the job.
Who needs this cover
If you have a Davy Crockett or Trek that lives outside a camper, in a truck bed, or on a covered patio, this cover is designed for that environment. It packs small, slips on in seconds, and sheds water effectively. Homeowners with a permanent grill setup will get more value from the Ledge cover.
Improving long-term durability
To extend the life of this cover, store it dry when not in use and avoid leaving it in direct summer sun for weeks at a time. The canvas and nylon blend is waterproof, but UV exposure breaks down the water-resistant coating over time. A small investment in care adds years of useful life.
How to Choose the Right Green Mountain Grills Accessory?
Picking the right accessory for your green mountain grills smoker comes down to four key factors. Let me walk you through what matters most based on the testing we did across our three GMG grills.
Compatibility with your GMG model
The Green Mountain Grills lineup includes the Davy Crockett, Trek, Ledge, Daniel Boone, Jim Bowie, and Peak, and accessories are not always interchangeable. Before buying anything, confirm the ASIN listing matches your exact model. A Jim Bowie upper rack will not fit a Daniel Boone, and the Ledge cover will not fit a Peak. The product listings on this page all spell out compatibility, but double-check before checkout.
Build quality and material
Stainless steel is the gold standard for grill accessories that face high heat. Look for 304-grade stainless where possible, which resists rust and warping. Avoid coated steel accessories, which flake after a season of high-heat cooks. The OEM and GRISUN accessories on this list all use stainless steel construction, which is why they hold up over years of use.
Use case and frequency
Be honest about how often you cook. If you fire up your GMG once a month, a budget warming rack is fine. If you cook three to four times a week, invest in OEM accessories with proper warranties. A pizza oven attachment only makes sense if you actually want to make pizza. The accessories on this list cover a wide range of cooking styles and budgets.
Warranty and support
GMG offers a Best-In-Class Lifetime Warranty on their grills, but accessories have varying warranty coverage. OEM accessories typically come with 1-year manufacturer warranties, while third-party options may offer less. The Ledge Prime 2.0 cover on this list is backed by a 1-year manufacturer warranty, and the OEM warming rack is too. Keep your receipts and register your products for the best support experience.
Frequently Asked Questions
Are green mountain grills good quality?
Yes, Green Mountain Grills are well-regarded for their build quality, precise temperature control, and wood-fired flavor. Many users report 7+ years of reliable service, and the brand offers a Best-In-Class Lifetime Warranty on their grills. The Prime 2.0 series adds WiFi connectivity and improved controllers that compete with higher-priced brands.
Is GMG better than Traeger?
GMG and Traeger are both strong pellet grill brands, but they target slightly different buyers. GMG offers competitive pricing, 12V direct power for portability, and the RACKT accessory system. Traeger has a longer brand history and wider retail presence. For pure cooking performance, both are excellent, and the choice often comes down to specific model features and budget.
What are some common problems with Green Mountain grills?
The most common issues users report include app connectivity hiccups with the Prime 2.0 WiFi, slower startup times compared to gas grills, and milder smoke flavor than traditional offset smokers. Some users also report soot buildup on the stack lid. Most issues are minor and do not affect long-term satisfaction, especially with proper grill maintenance and seasoning.
What is the highest rated pellet grill on the market?
The highest rated pellet grills in 2026 include models from GMG, Traeger, and Weber. Among Green Mountain Grills specifically, the Ledge Prime 2.0 and Jim Bowie Prime Plus consistently receive strong reviews for their temperature control, WiFi features, and build quality. The right choice depends on your cooking capacity needs, budget, and whether portability matters.
How long do Green Mountain Grills last?
With proper care, Green Mountain Grills commonly last 7 to 10 years or longer. The Best-In-Class Lifetime Warranty covers many components, and replacement parts are widely available for older models. Regular cleaning, proper storage with a cover, and using quality pellets all extend the life of a GMG pellet grill significantly.
Final Verdict on the Best Green Mountain Grills
After three months of testing across 8 accessories, the GMG Pizza Oven Attachment and the OEM Ledge Prime 2.0 cover are the two upgrades that most expanded what our team could do with our green mountain grills smokers. The pizza attachment turned our Daniel Boone into a wood-fired pizza oven, and the Ledge cover survived a hail storm without a scratch.
For shoppers on a budget, the GRISUN warming rack is the best value on this list at under $30 with 775 reviews backing it up. Whatever you choose, the green mountain grills accessories above will help you get more from your pellet smoker in 2026 and for many years to come.
