The Retrax RetraxPRO MX fits the 2020-2026 GMC Sierra 3500HD 8ft bed and delivers a retractable aluminum hard cover rated to hold 500 lbs of evenly distributed cargo.

Product Overview

The RetraxPRO MX is a retractable hard tonneau built from double-wall aluminum slats with a matte black powder coat finish. CoreTrax sealed rollers and the key-lockable TraxLatch handle let the cover lock at infinite positions along the rail.

An integrated water management system channels moisture through drain tubes to keep gear dry. The cover opens and closes independently of the tailgate and is rated for -40 to 180°F operation.

Clamp-on rails install in about 60 minutes with no drilling, and the cover is assembled in the USA with a lifetime warranty.
