Description
The ACCESS ROCKSTAR H4020279 mud-flap kit uses a smooth black urethane-coated aluminum support and a broad rubber flap for rear towing protection. It is intended for listed 2020-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 configurations.
This frame-mounted kit attaches beneath a compatible bumper using existing mounting locations; the hitch remains free because the flap does not hang from the receiver. It is designed around factory bumpers and cannot be used with a deployable bed step. Verify model, bumper and exhaust setup before installation.
