BAK Revolver X4S Hard Rolling Tonneau Cover to suit RAM 1500 DS | 2500 | w/out Rambox

The X4S is the current production model and includes a number of upgrades over the previous X4: a matte black aluminium underbody and clamps, side rail seals with a flat smooth design, a strap and buckle system to secure the rolled-up cover while driving, rear corner caps for a more modern appearance, an integrated bulkhead seal for improved weather resistance, and integrated safety slat caps that protect the slats during rolling. If you've seen older Revolver X4 stock on the market, the X4S is the updated version with these refinements included as standard.

No. This specific fitment is designed for RAM 1500 DS and 2500 models without RAMBOX. The RAMBOX system modifies the bed rail profile in a way that is not compatible with this cover. A different fitment would be required if your RAM has RAMBOX.

Yes. The automatic latch is designed to secure easily and release from either side of the bed, so you don't need to walk around the truck to open or close it. When the cover is fully rolled open, the new strap and buckle system keeps it secured against the cab while driving.

Yes. The Revolver X4S is designed to retain full access to the RAM's stake pocket holes. Accessories that mount via the stake pockets, bed extenders, cargo systems, and certain crossbar setups. These remain usable with the cover installed.

The cover clamps to the top of the bed rails, so a spray-in liner sitting below the rail surface generally won't interfere with installation or sealing. A drop-in liner with a thick or raised top rail cap may affect how the side rails sit or reduce sealing performance. It's worth checking your liner's top rail profile against the installation specs before purchasing. Contact us if you're unsure and we can help confirm compatibility.

BAK rates the Revolver X4S to support up to 200 lbs (approximately 90 kg) of evenly distributed weight when closed. This is suitable for light gear placed on top for transport, but the cover is not designed for heavy static loads or dynamic loading during off-road use. Always refer to BAK's current product specification for the most up-to-date load rating.

The Revolver X4S uses patented rotational locking rails that engage along the full length of the bed, rather than locking only at the tailgate end. This provides more consistent resistance across the whole cover compared to a single-point latch. Like any bed cover, it's designed as a strong deterrent rather than a vault. For high-value gear, a lockbox inside the covered tub adds a useful secondary layer of protection.

Rolling covers like the Revolver X4S are generally well suited to working applications where you regularly need full bed access. The cover rolls all the way to the cab, clearing the entire 6'4" bed, and the automatic latch lets you open it quickly from either side without walking around the truck. Compared to a hard folding cover, the roll-up design is faster to operate for repeated daily loading and unloading. The industrial-grade vinyl and rotational locking rails also hold up well to the kind of regular use a working truck sees.
