The new BAK Revolver X4s is the third generation of America's #1 selling premium hard rolling cover, now with exciting new features. Matte-black from top to bottom, the X4s is made from premium aluminum, and has newly designed side seals, and finished rear corner caps, to achieve a new level of refinement for your truck. This hard-rolling truck bed cover is engineered for real-world durability. Its heavy-duty slats are wrapped in industrial-grade vinyl to deliver precise protection. With the cover closed, the patented rotational locking system secures the X4s for the entire length of the bed, on both sides, contributing to unrivaled strength and security. When open, the Revolver X4s truck bed cover rolls forward smoothly, storing tight against the cab, and secures with a durable strap and buckle system. This design gives you full access to the truck's bed without obstructing your sightlines through your rearview mirror or third brake light visibility. Best of all, it's backed by BAK for 5 years.
