Description
Built for the distinctive GMC CarbonPro bed, the ACCESS LOMAX B3020109 is a low-profile hard tri-fold tonneau cover for selected Silverado and Sierra 1500 short-bed configurations. Its aluminum panels close neatly across the truck box without the bulk of an exposed roll-up cover.
The fitment is specific: a 5-foot-8-inch bed with a CarbonPro box, and no bedside storage box. It does not replace the separate non-CarbonPro version, even where the bed length sounds identical. Check the original bed construction and tailgate arrangement.
