BAK Revolver X4s
Hard Rolling Tonneau Cover

The BAK Revolver X4s is rated the #1 hard roll-up tonneau cover for 2026 by Automoblog, offering a modern take on the classic rolling tonneau with a premium aluminum slat construction that supports up to 400 lbs and provides serious cargo security.

Key Features

• Premium aluminum slats — significantly stronger than vinyl roll-ups
• 400 lb load-bearing capacity on the cover surface
• Drain tubes included — channels water out of the bed
• Lockable at any position for flexible cargo access
• Low-profile rail system for a sleek factory look
• No-drill installation on most truck models
• Rubber bumpers protect the cab when rolled up

Who Is This For?

The Revolver X4s is the ideal choice for truck owners who want the security and durability of a hard cover with the convenience of a roll-up design. Unlike tri-fold covers that stack panels at the front, the X4s rolls into a compact canister at the cab end — keeping your full sightline clear and providing continuous access to the bed at any point.
