Bed liners, bed mats and tailgate mats protect your Sierra 1500 bed from dents and scratches and keep cargo from sliding.
- Bed length: short, standard and long beds each take their own size.
- Year matters because bed shapes change between body styles.
- Existing liner: a mat can sit on a spray-in liner; a full drop-in liner replaces one.
Select your truck in the vehicle bar above to see liners 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.
