Finding the right GMC accessories can turn your truck or SUV into a more capable, comfortable, and personalized vehicle. In 2026, GMC drivers have a wide array of add-ons to choose from – OEM parts like bed covers, floor liners, running boards, and performance parts, as well as high-quality aftermarket gear. These accessories enhance utility (for example, protecting your cargo and cabin from the elements) and add style. GMC dealers emphasize using genuine parts to ensure perfect fit and durability.
In fact, with the GMC Sierra 1500 being one of the best-selling trucks (348,222 sold in 2025), many owners invest in accessories to protect their investment and customize their ride. Below we cover the must-have GMC truck and SUV accessories for 2026, organized by category and use case, with tips on fit and where to shop.

By selecting popular items from each category, you can create a well-rounded accessory package. For example, GMC’s official accessories store highlights bed covers compatible with Sierra, Sierra HD, Canyon, or the new HUMMER EV pickup, and dealers often promote rugged floor liners for year-round protection. These genuine GMC accessories are built to the manufacturer’s specifications, ensuring a precise fit and durable finish.
All-Weather Floor Liners & Cargo Mats
Keeping the interior clean and protected is a top priority. GMC offers precision-fit, premium all-weather floor liners (in jet black, dark ash gray, etc.) that cover the footwells from dirt, snow, and spills. These liners have deep channels to trap water and debris, and are made of TPE rubber that resists cracking in cold climates. Because they’re tailored to each model (e.g. Sierra crew cab, Yukon, etc.), they stay securely in place. Many owners also add cargo mats or liners for the trunk area on SUVs. The result is an interior that stays like-new through messy winters and road trips. According to an industry guide, custom heavy-duty floor mats are “among the top-recommended GMC accessories for drivers in regions with heavy snow or rain,” preventing interior damage.

Tonneau Covers & Bed Protection
For pickup trucks like the Sierra or Canyon, securing the cargo area is critical. GMC truck owners often install tonneau covers – rigid or soft – and bed liners for maximum protection. Retractable and folding hard covers protect tools and luggage from weather and theft, while also smoothing airflow. A retractable aluminum-slatted cover can be fully opened or locked in place. GMC notes that tonneau covers “secure cargo, improve aerodynamics, and can even slightly increase fuel efficiency”.
Types and Costs: Retractable covers (powered or manual) offer the most versatility; RealTruck prices these starting around $999. Hard roll-up covers (aluminum slats with seals) start near $1,049, while soft tri-fold or roll-up vinyl covers are more budget-friendly (soft covers from $289 and folding soft covers ~$299). One-piece fiberglass clamshell covers (OEM-style) start around $1,199. (Note: toolbox-compatible covers, which clear a crossover toolbox, start around $499.) These price ranges reflect current retailer data. GMC’s site emphasizes a “wide variety of options” so you can pick the design and price that fits your Sierra or Canyon.
Once installed, a tonneau cover keeps lumber, luggage or tools locked inside and dry. In addition, adding a spray-in or drop-in bed liner (or bed mat) prevents scratches and rust from hauling rough materials. For example, Bushwacker OE-style bed rail caps are popular add-ons to protect the bed walls. In sum, bed covers + liners are top GMC accessories for maintaining the truck’s utility and resale value.
Running Boards & Side Steps
Climbing into a lifted truck or tall SUV (like Yukon XL) is easier with steps. Running boards (aluminum or steel bars) and powered deployable steps provide safe footing and shield the rocker panels. According to GMC guidance, there are two main types: fixed “nerf bar” steps and auto-deploy power steps. Both add a rugged look while being functional. High-end GMC Denali and AT4 trims offer motorized steps that extend when a door opens, while simpler side bars are a DIY-friendly upgrade.
Owners should look for corrosion-resistant finishes; a quality step will be powder-coated steel or sturdy aluminum to handle salt and mud. Besides utility, steps prevent rocks and debris from hitting the lower body. In our dealer blog, Haggerty Buick GMC highlights “practical exterior accessories” like assist steps and bodyside molding, noting these choices are nearly endless for Sierra and Canyon trucks. In short, running boards are a classic GMC truck accessory for both safety and style.
Bed Slide, Utility Racks & Tool Boxes
GMC trucks shine when they’re well-organized. A bed slide (sliding tray) can extend your storage to the tailgate. GMC offers the BEDSLIDE® 1000 (a composite tray with a textured frame) which pulls out for easy access to tools and gear. It even mounts a spare tire underneath. Similarly, aluminum tool boxes bolt behind the cab or alongside the bed to lock away wrenches and fasteners. These stainless-steel toolboxes resist rust and include multiple compartments and trays for organization.
For overlanders or sportsmen, a truck bed utility rack (ladder-style) can carry kayaks, lumber, or roof-top gear above the bed. A roof-mounted rack or rack rails also expand cargo space for luggage boxes or bikes. GMC’s accessories catalog includes GearON™ cargo management systems (like sliding baskets and nets) for the interior and roof rack systems for the outside. These help keep pet crates, camping gear or work tools secure. For example, a strong roof rack atop a Yukon or Acadia can carry kayaks or a rooftop tent. In summary, look for lockable boxes, straps, and racks that add storage without clutter.
Cargo Nets & Interior Organizers
Inside the cabin, small accessories make life easier. Cargo nets (hooked in the bed or cargo area) stop smaller items from rolling around. In-vehicle consoles or organizers fit between front seats or under floorboards for phones and snacks. GMC’s parts dept. mentions “console organizers” and “rear cargo organizers” for trucks and SUVs. Even a first-aid kit or highway emergency kit (with jumper cables, flashlight, etc.) is a smart accessory for peace of mind. These practical add-ons help adapt the vehicle to daily use, whether you have kids, dogs, or gear to stow.
Exterior Styling & Protection
Many truck and SUV owners use accessories to personalize appearance. Popular items include grille guards, bull bars, and hood/bug deflectors, which protect the front end. Mud flaps and splash guards are often overlooked but help keep paint clean by blocking spray. In heavy off-road or winter use, extended mud flaps can reduce grime on the rear quarter panels by up to 40% according to testing.
Other cosmetic touches are also common: chrome or gloss-black grille inserts, door handle covers, mirror caps, and illuminated door sill plates add a premium look. For example, many AT4 and Denali owners install black or body-color Emblem kits to highlight the “SIERRA” badging. Even a tow hitch attachment like a hitch step adds utility and becomes part of the styling. All told, styling accessories serve dual purposes: they give your GMC a unique look while often adding a bit of protection (like guards preventing stone chips).
Wheels, Tires & Suspension
Upgrading wheels and tires is a common way to change your GMC’s stance and capability. Larger alloy wheels (20–22″ on full-size trucks) from GMC’s accessories collection offer new finishes (silver, matte black, etc.). Off-road tires or all-terrain tires improve traction for off-road adventures. Additionally, performance add-ons like chrome lug nuts or center caps are part of exterior packages. Some owners go further by adding a lift kit or leveling kit to fit bigger wheels – though this goes beyond simple accessories.
On the performance side, GMC’s parts catalog lists air intake kits and exhaust upgrades. For example, a cold-air intake can marginally boost horsepower, and a cat-back exhaust provides a more aggressive sound and slight power gain. These can be paired with tuning modules. For towing-focused owners, adding a higher-capacity radiator or transmission cooler might be advised, though these are more technical installs. In any case, GMC accessories for performance should match your engine and chassis (e.g. Sierra 1500 vs 2500HD may need different parts).
Interior Comfort & Technology
Finally, consider creature comforts. Rear-seat entertainment systems (headrest monitors, etc.), upgraded audio (speakers or subwoofers), and lighting kits (ambient LED strips) turn the cabin into a luxury space. Genuine GMC floor mats (carpeted all-weather) and seat covers can preserve the factory upholstery. Some drivers add heated steering wheels or upgraded shift knobs. Ambient lighting kits can illuminate the footwells or cup holders. All of these are available through GMC’s accessories store or aftermarket retailers. Keep in mind: anything with electronics (like video screens or navigation hooks) may require professional installation to avoid wiring issues.
Throughout all these categories, compatibility is key. Not every accessory fits every model or year. For instance, GMC Silverado/Sierra trucks had a refreshed design in 2025, and some older trim parts (bumper brackets, etc.) may not fit new models. Always confirm fitment by model year, cab style, and bed length. Most dealers and online parts stores let you search by VIN. Using OEM GMC accessories or well-reviewed aftermarket brands ensures the pieces align properly and carry some warranty. As one guide advises, verify fitment with your VIN or trim before buying to avoid costly mismatches.
Where to Buy GMC Accessories
You can purchase GMC accessories through multiple channels: the official GMC Accessories website, authorized dealerships’ parts departments, and specialty retailers. GMC’s online store often runs promotions (e.g. 20% off floor & interior items as of early 2026), and GM Rewards points can apply on purchases. Local GMC or Buick/GMC dealers typically stock popular items and can offer installation.
For example, Haggerty Buick GMC notes that “GMC’s accessories store can provide cargo management solutions” like roof racks and interior organizers. Reputable aftermarket suppliers (e.g. RealTruck, WeatherTech, Husky Liners) also sell many of these parts.
Tip: OEM (genuine) accessories guarantee a precise fit and often include warranties. Aftermarket parts can be high quality too, but check reviews and return policies. Always keep a record of part numbers and receipts in case you want to transfer the warranty to a new owner later.
FAQs
What are the best GMC accessories for trucks and SUVs?
Must-have GMC accessories include all-weather floor liners and cargo mats (to protect the interior), tonneau covers (for securing the truck bed), running boards or side steps (for easy entry), and cargo management items (like roof racks and bed organizers). Other popular choices are floor cargo nets, highway emergency kits, and illuminated door sill plates. These upgrades are practical for daily driving and adventures.
How do I choose the right tonneau cover for my GMC truck?
Decide based on use: Soft roll-up covers are lightweight and affordable (~$289 start). Hard tri-fold/folding covers provide stronger security ($299+) but still allow partial access. Retractable covers (manual or powered) offer full flexibility and have a low profile (~$999 start). Match the cover to your cab size (Crew Cab vs Double Cab) and bed length. Also check if you have a toolbox (use a toolbox-compatible cover). For best fit, use GMC’s online part finder or consult a dealer.
Can I install GMC accessories myself?
Many accessories are straightforward (floor liners, mats, mud flaps, decals). Basic toolbox installs or snap-on mudguards are DIY-friendly. However, items like running boards, bed slides, and most electronic add-ons can be complex. GMC recommends professional installation for powered steps, electrical components, or anything involving drilling. Always follow installation instructions carefully. When in doubt, a dealership service center can handle fitting accessories to ensure factory-quality installation.
Do OEM GMC accessories affect my warranty?
No, installing genuine GMC accessories does not void your new-vehicle warranty, as long as they are properly installed. OEM parts are engineered by the manufacturer and are covered. Even for aftermarket accessories, warranties on the parts themselves should be separate from your vehicle warranty. Just be sure the part doesn’t damage the vehicle; for instance, a poorly installed electrical accessory could void coverage for related issues. In general, buying from GMC or GM-authorized sources is the safest way to maintain warranty coverage.
How do GMC accessories compare to aftermarket options?
GMC accessories (OEM) guarantee compatibility and often offer a branded look (like logoed floor mats). Aftermarket parts can be less expensive or have more style choices (e.g. flashy lift kits or niche off-road parts). The trade-off is fit and finish: some aftermarket covers or liners may not fit as snugly. To minimize risk, buy well-known brands that support your vehicle model. And remember, even if an accessory is aftermarket, you can still use it with your GMC just verify it’s marketed for your specific make and year.
