2003 GMC Sierra 2500HD - Conductor's Special 244K Spare Tire Delete Kit and Tire Inflation Kit

Justin R. just transformed his 2003 GMC Sierra 2500HD into an absolute powerhouse of sound with our Conductor’s Special 244K Spare Tire Delete Kit! Not only does this setup deliver serious horn power, but it also adds practical functionality with the Tire Inflation Kit.

:camera_flash: Key Features of Justin’s Setup:

  • Shocker XL 4 Horns: Producing an thunderous 147.7 decibels, these horns deliver the unmistakable, commanding sound of a train. :steam_locomotive::boom:
  • Spare Tire Delete Bracket: A sleek, space-saving installation that mounts perfectly in place of the spare tire for a clean look and easy access.
  • Tire Inflation Kit: Adds convenience and utility, allowing Justin to inflate tires and other accessories on the go.
  • GMC Sierra 2500HD Power: This heavy-duty truck is the perfect match for a heavy-duty horn setup!



Justin’s Sierra 2500HD is the perfect blend of style, functionality, and LOUD performance. Whether he’s on the road or off the beaten path, everyone will hear him coming (from a mile away!).
