COMNOVA 6-Inch Running Boards for 2020–2026 GMC Sierra 2500HD Crew Cab
Brand: COMNOVA AUTOPART | Best for: Crew cab 2500HD/3500HD owners who want a bolt-on, no-drill solution with serious load capacity
With a 500 lb per bar weight capacity and a US-patented slider design that lets you adjust the board’s position forward or backward, COMNOVA’s crew cab boards stand out as the most customizable fixed step on this list. They’re built from heavy-duty carbon steel with an anti-rust powder coat finish that includes a subtle glitter texture — functional and sharp-looking.
Fitment is specific: these work with the 2020–2026 Silverado/Sierra 2500HD 3500HD Crew Cab (4 full-size doors) new body style only. They will not fit 2019 2500HD/3500HD models or the Double/Extended cab configuration. Owners consistently report a clean, flush fit that looks nearly OEM when installed correctly.
Skip if: you have a Double Cab (2 full + 2 half doors) — check Product 3 instead.
✅ Pros
- 500 lb load capacity per bar
- US-patented adjustable slider design
- No drilling required — bolt-on only
- OE-style look with anti-glitter powder coat
- Four brackets per side for solid support
❌ Cons
- Crew Cab only — no Double Cab fit
- Won’t fit 2019 2500HD/3500HD models
- Carbon steel is heavier than aluminum options
AUTOSAVER88 6-Inch Running Boards for 2020–2026 Sierra 2500HD/3500HD Crew Cab
Brand: AUTOSAVER88 | Best for: Budget-conscious buyers who want stainless durability without overpaying
AUTOSAVER88 delivers a stainless steel construction with rust-resistant powder coating — a material advantage over many carbon steel competitors at the same or higher price point. The one-piece design means there are fewer weak points, and reviewers note it installs cleanly using factory mount holes with no drilling in under an hour.
The 6-inch non-slip injection step pad is rated at 450 lbs capacity, which is solid for most real-world use. Owners consistently report that the factory hole alignment is accurate and installation is genuinely straightforward, even for first-timers. It fits 2019–2026 Silverado/Sierra 1500 and 2020–2026 2500HD/3500HD Crew Cab configurations.
Skip if: you need the absolute maximum load capacity or prefer a slider adjustment feature — this is a fixed-position board.
✅ Pros
- Stainless steel — lighter and more rust-resistant than carbon steel
- One-piece construction reduces weak points
- Factory hole alignment — no drilling needed
- Fits both 1500 and 2500HD/3500HD platforms
- Budget-friendly price point
❌ Cons
- 450 lb capacity vs 500 lb on COMNOVA
- No adjustable slider position
- Professional install still recommended per brand
💡 Pro Tip
Always confirm your exact cab style before ordering. The GMC Sierra 2500HD comes in Crew Cab (4 full-size doors) and Double Cab (2 full + 2 smaller rear doors). Running boards are NOT interchangeable between these configurations — using the wrong fitment will leave you with boards that don’t align with the door openings. Check your window sticker or VIN decoder if unsure. You can also check our guide to identifying your GMC Sierra cab style.
COMNOVA 6-Inch Double Cab Running Boards for 2020–2026 GMC Sierra 2500HD
Brand: COMNOVA AUTOPART | Best for: Double Cab 2500HD/3500HD owners who want UV-resistant, OE-style boards with salt-spray protection
This is COMNOVA’s Double Cab-specific board — it fits the 2020–2026 Silverado/Sierra 2500HD 3500HD with 2 full-size doors and 2 half-size doors (Extended/Double Cab configuration). It features the same innovative slider design as Product 1, letting you dial in the forward/backward position for perfect door-opening alignment.
The standout here is materials: the carbon steel frame is rated to resist salt spray corrosion and UV radiation without discoloring — a genuine plus if you live in the rust belt or sunbelt. The glitter-infused powder coat also adds a styling touch that reviewers note looks surprisingly premium in person. Owners report a straightforward install that mirrors the Crew Cab version.
Skip if: your Sierra 2500HD is a Crew Cab (4 full-size doors) — get Product 1 instead. Also note: does NOT fit 2019 2500HD or older body styles.
✅ Pros
- Built specifically for Double Cab fitment
- Salt-spray and UV corrosion resistance
- Adjustable slider for custom positioning
- Glitter powder coat for upscale look
- No drilling required
❌ Cons
- Won’t fit Crew Cab — easy to order wrong version
- Not compatible with 2019 2500HD/3500HD
- Carbon steel adds weight vs aluminum builds
WOLFBOX Power Running Boards for 2024–2025 GMC Sierra 2500HD/3500HD Crew Cab
Brand: WOLFBOX | Best for: Truck owners who want an electric retractable step with built-in LED lighting and OEM-quality appearance
If you want the cleanest look possible — steps that disappear when you’re not using them — the WOLFBOX Power Running Boards are the top pick. These electric retractable boards extend automatically when you open the door and retract flush to the truck body when you close it. The 660 lb load capacity is the highest on this list and industry-leading for powered steps.
Built from rustproof aluminum with a slip-resistant surface, the WOLFBOX steps include automatic LED lighting that illuminates the step zone at night — a feature owners consistently describe as genuinely useful for dark parking lots and job sites. No drilling required, and WOLFBOX backs these with a 5-year warranty, which is exceptional in this category.
Skip if: your budget is tight (power steps cost significantly more than fixed boards), or if you have a 2022–2023 2500HD (fitment only covers 2024–2026 for the HD models). For 1500 models, compatibility runs 2022–2026 Crew Cab.
✅ Pros
- Industry-leading 660 lb capacity
- Auto-retract for cleaner appearance between uses
- Built-in LED step lighting — auto-activates at night
- Rustproof aluminum construction
- 5-year warranty — best on this list
- No drilling — OEM-like fitment
❌ Cons
- Premium price point — considerably more expensive
- 2500HD fitment limited to 2024–2026 only
- Requires wiring connection to door trigger circuit
- Moving parts = more long-term maintenance potential
⚠️ Warning
If your GMC Sierra 2500HD has a diesel engine with a DEF (Diesel Exhaust Fluid) tank, double-check fitment notes carefully. Some running boards interfere with DEF tank access on the driver’s side. The WOLFBOX power boards specifically note compatibility WITH diesel/DEF models — but always verify with your dealer or manufacturer before ordering.
AUTOSAVER88 6.5-Inch Stainless Running Boards for 2020–2026 Sierra 2500HD Crew Cab
Brand: AUTOSAVER88 | Best for: Crew Cab owners who want a slightly wider step pad and premium stainless steel aesthetics
AUTOSAVER88’s 6.5-inch version bumps the step pad width by half an inch over their standard model — a small but meaningful difference when you’re stepping down from a lifted 2500HD in work boots. The stainless steel one-piece construction with rust-resistant powder coating gives this board excellent longevity, and owners consistently report it holds up well through harsh winters and salt-heavy roads.
At 450 lbs per side capacity and bolt-on installation aligned to factory mounting holes, this board is nearly identical in process to Product 2 — but the wider, textured black pad earns extra points from reviewers who prioritize grip over aesthetics. It also fits the 2019–2026 1500 platform alongside the 2020–2026 2500HD/3500HD Crew Cab.
Skip if: you need Double Cab fitment, or if you want the adjustable slider that COMNOVA offers.
✅ Pros
- 6.5-inch pad — widest fixed step on this list
- Premium stainless steel one-piece build
- Textured black step pad for superior grip
- No-drill, factory-hole bolt-on install
- Fits both 1500 and 2500HD/3500HD platforms
❌ Cons
- Crew Cab only — no Double Cab variant
- 450 lb capacity, not 500 lb like COMNOVA
- No slider position adjustment

🛒 Buyer’s Guide: How to Choose Running Boards for Your GMC 2500HD 2026
1. Confirm Your Cab Style First
This is the single most common ordering mistake. The GMC Sierra 2500HD comes in Crew Cab (4 identical full-size doors) and Double/Extended Cab (2 full-size front + 2 smaller rear doors). Running boards are designed for one or the other — the board lengths and bracket positions are different. Check your window sticker or the manufacturer’s fit guide before you checkout.
2. Fixed vs. Power/Electric Steps
Fixed boards (Products 1–3, 5) are always extended, less expensive, and have no moving parts to maintain. Electric/power steps (Product 4) retract automatically, look cleaner when driving, and offer higher load capacities — but cost significantly more and require wiring. If you’re primarily a work truck driver, fixed boards are the practical default. If aesthetics and tech features matter, power steps are worth the investment.
3. Material: Carbon Steel vs. Stainless Steel vs. Aluminum
Carbon steel (COMNOVA) is strong and heavy, but requires quality powder coating to prevent rust — which both COMNOVA boards include. Stainless steel (AUTOSAVER88) is naturally rust-resistant, lighter, and easier to maintain. Aluminum (WOLFBOX) is the lightest and most rust-proof, but typically reserved for premium power step builds. For the rust belt, stainless or aluminum are the smarter long-term material choices.
4. Step Width and Load Capacity
Most boards here are 6 inches wide — enough for a solid platform step. The AUTOSAVER88 6.5-inch version gives a bit more real estate, which matters in winter gear or work boots. Load capacity ranges from 450 lb to 660 lb across this list. For most drivers, 450 lbs is more than adequate. If you frequently carry heavy equipment or assist elderly passengers, prioritize the higher-rated boards.
5. Installation Complexity
All five products on this list are designed for no-drill bolt-on installation using existing factory mounting holes. That said, complexity varies slightly — power steps require wiring, and COMNOVA’s slider design needs a few extra positioning adjustments. Budget around 45–90 minutes for a fixed board install and 2–3 hours for a power step. For more truck upgrade tips, check out our guide to the best truck accessories for GMC Sierra owners.
❓ Frequently Asked Questions
Q: Do running boards fit the 2026 GMC Sierra 2500HD the same as the 2024–2025 models?
Yes — for the products listed here, the 2026 model year shares the same body mounting points as the 2020–2026 generation. All five boards listed are confirmed compatible with the 2026 2500HD (in their respective cab styles). Always double-check the fitment guide on the product page for your specific trim and cab configuration.
Q: Will these running boards fit a 2019 GMC Sierra 2500HD?
No — the 2019 2500HD/3500HD uses an older body style and different mounting points. Every product on this list explicitly excludes the 2019 2500HD/3500HD. If you have a 2019 model, you’ll need to search for a running board listed as fitting the “2015–2019 body style” instead of the current generation.
Q: Can I install these running boards myself, or do I need a shop?
All fixed running boards on this list are designed for DIY bolt-on installation using existing factory holes — no drilling needed. Most owners complete the install in under an hour with basic hand tools. Power steps (WOLFBOX) require connecting to your truck’s door trigger wiring harness, which is more involved but still achievable with automotive wiring knowledge. AUTOSAVER88 recommends professional installation as a precaution, but the majority of reviewers complete it themselves without issue.
Q: What’s the difference between a running board and a nerf bar for the 2500HD?
Running boards are flat platform steps — typically 6+ inches wide — that run the full length of the cab. Nerf bars are tubular round or oval steps that provide a single foothold point. Running boards offer a larger step surface (better for families and work use), while nerf bars are lighter and have a sportier appearance. All five products in this article are running boards, not nerf bars.
Q: Are power running boards worth the extra cost for a work truck?
It depends on your priorities. If you use your 2500HD as a daily driver where aesthetics matter, power steps like the WOLFBOX keep the truck looking clean. On a work truck that takes a beating, fixed boards (no electronics to fail, easier to repair) are almost always the more practical choice. The WOLFBOX’s 5-year warranty does help reduce the risk concern significantly if you do decide to go electric.
Q: Will running boards affect my ground clearance on the 2500HD?
Fixed running boards do extend downward beyond the rocker panel, which can slightly reduce effective ground clearance on extreme angles. On the 2500HD, which has considerable factory ride height, this is rarely a practical issue for road and light off-road use. If you’re rock crawling or running serious off-road terrain, retractable power steps (which fold up out of the way) are the better choice to protect the boards from trail damage.
Ready to Upgrade Your GMC 2500HD?
Don’t let another day of awkward cab entry go by. Whether you pick COMNOVA’s 500 lb bolt-on boards, AUTOSAVER88’s stainless-steel value option, or WOLFBOX’s premium power step, you’re getting a durable, properly-fitted upgrade that makes your truck safer and sharper-looking.
All five options above are direct fits for the 2026 GMC Sierra 2500HD (in their respective cab styles) — just confirm your crew vs. double cab configuration and you’re good to go.
