## Description

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. Expect More.

Review: I love this cover! Worth the pricing! - To set the stage for why this cover is so great... I previously had a different tonnaeu cover that was a folding one that had 4 panels / 3 folds. To fold it back required me to undo two clamps at the back, secure the clamps, fold it two times, unclamp two clamps at the middle on each side of the truck (requiring me to go around the truck or have a second set of hands), and then fold again... it was a pain in the butt, and the rear clamps would often disengage at the slightest brush or bump so it wasn't uncommon to see a corner flapping in the wind. My girlfriend absolutely hated the old cover, particularly whenever we'd require folding it to get at stuff that was shifted to the front side of the bed. So I bit the bullet for the Revolver X4s, a bit pricier than I wanted to spend but I'd seen another truck owner with the similar X2 and I decided it was the cover I wanted as it hit all the checkmarks. It's exactly as advertised. It's solid, and I feel it's more secure and secures my stuff in my truck bed better than the old vinyl cover. It's easy, I can open and close it entirely myself with one hand, and it makes it so much easier to access the full contents of the truck bed. It's beautiful and goes very well with the truck. I definitely would recommend to anyone else looking for a cover.
Review: Great - Have had Discover for a while now very durable and it works great with no sign of where couldn’t ask for better
