Running boards, nerf bars and side steps make it easier to climb into your Sierra 1500 and help protect the rocker panels from rocks and road spray.
- Cab style sets the length: Regular, Double and Crew Cab trucks each take their own size.
- Year matters because mounting points change between body styles.
- Style: flat running boards give a wide step, round nerf bars a cleaner look, and drop steps the most help for lifted trucks.
Select your truck in the vehicle bar above to see only steps that fit.

GMC Sierra 1500 fitment tips
- Sierra and Silverado beds are the same sizes (5 ft 10 in, 6 ft 7 in and 8 ft), but front bumpers, grille guards and lighting are GMC-specific.
- The 2022 refresh split many front-end fitments into 2019–2021 and 2022+.
- AT4 and AT4X models have factory lift and unique bumpers, so check fitment notes for leveling and lift kits.
- The MultiPro tailgate can affect tailgate seals and some bed covers.
- Not sure about your trim, cab or bed length? Use the vehicle selector at the top of the page, or contact us with your VIN and we'll confirm fitment before you order.
