Description
This MX4 has neither a low-profile design nor a front hinge. A matching composite CarbonPro bed is required for its three textured matte-black aluminum hard-folding sections. Inside-bed clamps need no drilling, and locking uses the tailgate handle.
Compatibility
Intended for matching 2019–2021 GMC Sierra 1500 composite/CarbonPro short-bed applications, nominally 5 ft 8 in. Confirm the 69.9-inch bed and trim configuration.
