America's #1 Selling Hard Rolling Cover

The BAK Revolver X4, is a premium hard rolling cover that includes all the same great features of the Revolver X2, now with a stylish matte black finish. When closed, heavy-duty aluminum slats secure the cover the full length of the bed on both sides, providing unrivaled strength and security. When opened, the cover rolls up tight providing full bed access without blocking rear view mirror and third brake light visibility.

The RX4 is constructed of heavy-duty aluminum panels. When latched, the ¾” Patented Rotational Locking Rails secure the cover the entire length of the truck bed. Heavy-duty locking levers are now 3X thicker with reinforced gussets for added strength and are engineered to lock with no adjustment necessary.

  • Premium matte finish hard rolling cover
  • Patented rotational locking rails lock 100% of the cover for unrivaled security
  • Automatic latching system
  • 5-year warranty
