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.

Heavy-duty locking levers are now 3X thicker with reinforced gussets for added strength and are engineered to lock with no adjustment necessary.
