BAK Revolver X4TS T-Slot Tonneau Cover
The BAK Revolver X4TS combines our proven rolling slat design with integrated T-slot rails, giving you a secure bed cover that doubles as a mounting platform. Hard aluminum slats lock your cargo away from weather and prying hands, while dual T-slot channels along each rail accept aftermarket crossbars, bike mounts, cargo carriers, and work accessories without drilling through the cover.
We engineered the X4TS for truck owners who need flexibility — from weekend adventures to job-site duty. The matte black finish resists UV fade and won't glare in your mirrors. Roll the cover open from either side, or position it anywhere along the bed to haul tall loads. Built in our USA facility with the same aluminum and stainless steel we've trusted for two decades.
Core specs & build details
Aluminum slat construction & finish durability
Every slat in the BAK Revolver X4TS is extruded from 6000-series aluminum alloy, the same grade we use across our entire hard-cover lineup. The interlocking profile creates a continuous seal when closed, keeping rain, snow, and road spray out of your bed. We apply a matte black powder coat that resists chips and stands up to UV exposure without fading to gray.
The aluminum construction saves weight compared to fiberglass or steel lids — the entire assembly weighs around 70 pounds installed, so one person can handle installation without help. Stainless steel hinge pins connect each slat to the next, and self-lubricating UHMW polymer sliders eliminate metal-on-metal friction as the cover rolls open and closed.
T-slot rail system for mounting accessories
The defining feature of the X4TS is the pair of T-slot channels machined into the top surface of each side rail. These slots accept standard T-bolt hardware, letting you mount crossbars, kayak carriers, bike racks, ladder racks, and work accessories directly to the cover rails without drilling holes or removing the tonneau.
We designed the T-slot profile to match common aftermarket rack systems, so you’re not locked into proprietary hardware. The slots run the full length of each rail, giving you flexibility to position mounts exactly where you need them. When you’re not carrying external loads, the slots sit flush with the rail surface and don’t interfere with the cover’s operation.
Installation & bed compatibility
The bak revolver x4ts installs with our clamp-on rail system — no drilling, no permanent changes to your truck bed. Aluminum side rails secure to the top of your bed rails with stainless steel clamps spaced every 12 inches. The canister housing mounts at the cab end and holds the rolled slats when the cover is open.
We manufacture fitment-specific rails for most full-size domestic and import trucks with 5.5-foot, 6.5-foot, and 8-foot beds. Each kit includes rail shims to match your exact bed width and compensate for rail cap profiles. Installation typically takes one person 20 to 30 minutes with basic hand tools. The cover works with most drop-in bedliners, spray-in liners, and bare beds.

Common questions about the BAK Revolver X4TS
Yes, the X4TS rail system clamps onto the top edge of your bed rails and does not interfere with spray-in liners like Line-X or Rhino Linings. We include rail shims in every kit to adjust for slight variations in bed width caused by liner thickness. The canister housing and side rails sit above the liner surface, so there is no contact that would damage the coating.
The T-slot channels accept any aftermarket rack system that uses standard T-bolt or T-nut hardware. Common compatible products include Thule and Yakima crossbars, ladder racks, bike mounts, ski carriers, and cargo baskets. The slot profile matches industry-standard dimensions, so you are not limited to BAK-branded accessories. Verify that your chosen rack's T-bolt size matches the slot width before purchasing.
The BAK Revolver X4TS is rated for 300 pounds of evenly distributed weight when the cover is fully closed and latched. This rating assumes the load is spread across multiple slats using crossbars or a rack platform. Do not concentrate weight on a single slat, stand on the cover, or exceed the 300-pound total. For heavier cargo, use your truck bed with the cover rolled open into the canister.
The X4TS uses self-lubricating UHMW polymer sliders that do not need grease or oil. We recommend hosing off the slats and rails every few months to remove road salt, dirt, and debris that can accumulate in the T-slot channels. Wipe down the powder-coat finish with a damp cloth if it gets dusty. Inspect the stainless steel clamps annually to ensure they remain tight, especially if you drive on rough roads or carry heavy rack loads.
No, the rotary latch handle is located at the tailgate, so you need tailgate access to unlock and roll the cover open. This design provides added security — someone cannot access your bed without first unlocking your tailgate. If you use an aftermarket tailgate lock, you can typically key the tonneau latch cylinder to match your truck's ignition for convenience.
Yes, the X4TS side rails mount to the top edge of your bed rails and do not block access to factory tie-down hooks located inside the bed. You can still use D-rings, cleats, and factory anchor points to secure cargo. The cover's slat design also allows you to tie down cargo under the closed cover using the factory hooks at the bed corners.
The canister housing measures approximately 11 inches from the front edge of the bed when installed. This dimension is consistent across all bed lengths, so a short-bed truck loses a slightly larger percentage of bed space than a long-bed model. When the cover is fully rolled open, all slats store inside the canister and the rest of your bed remains clear for loading tall cargo.
