Frequently Asked Questions

Does the Revolver X4s 80133 fit both 2500 and 3500 HD trucks?
Yes. The 80133 fits 2020-2021 Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD all with the 6-foot-10-inch bed configuration.

How does the Revolver X4s 80133 lock?
The 80133 uses patented rotational locking rails and automatic slam latches that engage when the cover is closed and the tailgate is shut. This Level-3 security prevents prying and forced entry.

Is the Revolver X4s 80133 waterproof?
Yes. The one-piece TriShield vinyl surface has no seams, eliminating leak points. Flush side seals and an integrated bulkhead seal at the cab end prevent water from entering the bed.

How much weight can the Revolver X4s 80133 support?
The 80133 supports up to 400 lbs of evenly distributed weight when the cover is closed and rolled flat over the bed.

Does the Revolver X4s 80133 provide full bed access?
Yes. Roll the cover fully toward the cab and secure it with the integrated safety straps. This provides 100 percent access to the entire 6-foot-10-inch bed.

Does the Revolver X4s 80133 require drilling?
No. The 80133 uses a no-drill, clamp-on mounting system with factory-style hardware. Installation takes less than one hour with basic hand tools.

Will the Revolver X4s 80133 work with a factory spray-in bed liner?
Yes. The clamp-on rails sit on top of the bed rails, making the 80133 compatible with spray-in and drop-in bed liners.

Does the Revolver X4s 80133 work with the factory bed cargo management system?
The 80133 will NOT work with factory bed storage boxes. Check compatibility with any factory cargo management rail or cleat system before purchasing.

Installation Steps

  1. Remove any factory accessories that may interfere with rail placement along the bed rail.
  2. Place the Revolver X4s 80133 assembly in the truck bed and position the side rails on the inner top lip of the bed rails.
  3. Insert the clamp brackets into the rail channels at the front, center, and rear positions on both sides.
  4. Finger-tighten the clamps to hold the rails in position, then check for level alignment front to back.
  5. Torque all clamp bolts to the specification in the included instructions.
  6. Connect the rear bulkhead seal at the cab end of the cover.
  7. Roll the cover fully closed and verify the slam latches engage securely on both sides.
  8. Roll the cover open and secure with the integrated safety straps. Confirm the cover is stable in the open position before driving.

BAK

BAK Industries has built its reputation on hard-folding and rolling truck bed covers that combine security, all-weather protection, and low-profile styling that does not compromise truck aesthetics. Made in the USA by a RealTruck brand, every BAK tonneau cover is engineered with application-specific fitment for a leak-resistant seal and tool-free installation on most trucks.

Tonneau Covers - Roll Up

Tonneau Covers - Roll Up

Roll up tonneau covers give truck owners fast access to the bed without removing the cover entirely. Soft vinyl and aluminum roll-up designs clamp to the bed rails without drilling, weigh less than folding or retractable alternatives, and roll compactly behind the cab when fully open. Popular Roll Up Tonneau Cover Types Soft roll-up covers use reinforced vinyl stretched over a bow system and are among the most affordable tonneau options available. Aluminum roll-up covers use rigid interlocking slats that roll into a profile above the rear of the cab, providing better weather resistance and a more secure closure than soft vinyl designs. Both styles are available for all major full-size and mid-size truck platforms. How do I secure a roll up tonneau cover? Most soft roll-up tonneau covers use side-mounted tension clamps and hook-and-loop or snap fasteners at the tailgate to create a weatherproof seal. Aluminum slatted roll-up covers typically lock at the fully closed position via a la...
