BAK Revolver X4s Hard Roll-Up Tonneau Cover

The BAK Revolver X4s is what you buy when you want a roll-up that a thief cannot get through. Under the matte vinyl skin are patented interlocking aluminum slats, and around the bed are patented rotational locking rails that engage the full length of the cover with automatic slam latches. That combination is why the X4s carries BAK's highest Level-3 security rating and why hook-and-loop soft covers are not really in the same conversation. This page is the model hub for the whole X4s line. Pick your year, make, model, and bed below and we will route you to the exact part number for your truck.

The slats are the other half of the story. They are slash-resistant, they hold 400 lb evenly distributed across the closed cover, and because the X4s rolls onto a spool at the bulkhead instead of retracting into a canister, you keep all of that bed space for cargo. Roll it forward with PrecisionRoll, strap it down with the integrated tethers, and drive with the bed fully open and your rear window and factory cameras unobstructed.

Weather is handled by TriShield engineering: a one-piece, aluminum-reinforced 70-grade vinyl surface with no seams to leak through, flush-fitting side seals, and an integrated bulkhead seal. The whole assembly wears a 360-degree matte finish across the slats, clamps, and hardware, so it sits nearly flush with your bed rails and reads as part of the truck rather than an accessory bolted to it.

Installation is clamp-on to your factory bed rails with no drilling, typically an hour or less. Every X4s carries a 5-year limited warranty backed by US-based support. If you want the same cover with integrated T-slot rack rails for crossbars, carriers, and tents, look at the Revolver X4 TS. If you want the Revolver operation at a lower price and can live with a 3-year warranty, look at the Revolver X2.

Features

The Most Secure Hard Roll-Up
Patented rotational locking rails run the full length of the bed and engage automatic slam latches as the cover closes, resisting prying, slicing, and forced entry. This is BAK's highest Level-3 security rating, and it is the reason the X4s outsells the soft roll-ups it looks like from a distance.

Patented Slash-Resistant Slats, More Cargo Space
The interlocking aluminum slats under the vinyl skin are built to defeat a blade and carry 400 lb evenly distributed on the closed cover. Because the X4s rolls onto a spool at the bulkhead rather than into a canister, you get retractable-grade security without giving up bed length to hardware.

TriShield Engineering Means No Seams and No Leaks
The one-piece, aluminum-reinforced TriShield 70-grade vinyl surface has nothing to seam and therefore nothing to leak through. Flush-fitting side seals and an integrated bulkhead seal close the perimeter, and water runs off the cover and out through the bed.

Full Access Plus Full Visibility
Roll the cover forward with PrecisionRoll technology, secure it with the integrated safety straps, and drive with 100 percent of the bed open. The rolled cover sits low at the bulkhead, so your rear window and factory backup cameras stay clear.

Lowest-Profile Hard Roll-Up
The X4s sits nearly flush with your bed rails, low enough that from the side it reads as part of the truck's original lines rather than something added. That matters for looks and it matters for the small aerodynamic penalty a tall cover carries.

Ultimate 360 Degree Protective Finish
Matte black runs across the slats, the clamps, and the hardware, not just the visible top surface. The 70-grade TriShield vinyl resists dust and staining, so the cover keeps looking new instead of graying out after a couple of summers.

Every X4s installs the same way regardless of truck. Set the driver and passenger side rails on your factory bed rails, square them up and tighten the included clamps, then drop in the cover and connect the tension adjusters. No drilling into the truck. The BAK Revolver install sheet gives clamp placement and torque for your specific part number.
