2001-2018 GMC Sierra Classic / HD Tonneau Conversion Kit | Leitner Designs ACS Forged Tonneau
Choose options
Already running an ACS Forged bed rack on your Sierra? This kit converts it to work with a T-Slot Rail retractable tonneau cover — so you can keep your existing rack and add covered storage underneath at the same time.
What this kit does
The ACS Forged Tonneau Conversion Kit replaces the standard mounting rails on your existing ACS Forged bed rack with T-Slot Rail-compatible rails. Once installed, your rack mounts to and operates with a compatible T-Slot Rail retractable tonneau cover, giving you a covered bed below and your full ACS modular system on top.
This is the rail hardware only — it does not include a rack or a cover.
What you need
- An existing ACS Forged bed rack already installed on your Sierra
- A compatible T-Slot Rail tonneau cover — ReTrax XR Series or Pace Edwards Explorer Series. A powered cover is strongly recommended so you can open and close it with the rack fully loaded.
Compatibility notes
- Fits 2001-2018 GMC Sierra Classic and HD in 6'6" bed configuration
- The rear load bar does not slide after conversion
