2023 GMC Sierra 2500 HD fitment tips

  • Beds are 6 ft 9 in (standard) or 8 ft 2 in (long) - match covers, toolboxes and transfer tanks to yours.
  • The 2024 refresh changed the front fascia, so many bumpers and grille guards are split into 2020-2023 and 2024+.
  • 3500 dually trucks need DRW-specific fender flares and running boards.
  • Factory-lifted trims like ZR2 and AT4X do not need leveling kits and may not accept standard lift kits.
  • 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 will confirm fitment before you order.
