These are the T-slot rack rails that make a BAK Revolver X4 TS rack-ready, sold on their own as a matched pair. If a rail on your cover was damaged in a parking garage, went missing when the truck changed hands, or you bought an X4 TS cover without its rails, this is the kit that puts the rack capability back. Rails only; the roll-up cover is not included. This page is the hub for the whole rail kit range. Pick your truck below and we will route you to the pair matched to your cover.
A rail kit is a system-fit part rather than a vehicle-fit part. The rails are cut to the length of a specific X4 TS cover, so what you are really matching is the cover you already own, and the truck selector is how we get you to that cover's rail set. Each kit ships as a pair, driver and passenger, with the clamp hardware needed to mount them.
What the rails do is the same on every truck. Full-length T-slot channels run down both sides of the cover and accept standard T-slot rack hardware: crossbars, cargo baskets, bike and kayak carriers, ladder racks, and roof-top tents, all sold separately. Because the channels are machined into the cover's own rails rather than bolted over the bed sides, anything you mount to them starts lower and reads cleaner on the truck.
Installation matches the cover itself. The rails clamp to your factory bed rails with the included hardware, so there is no cutting and no drilling, and most people are done in twenty to forty minutes with basic hand tools. Follow the BAK Revolver install sheet for clamp placement and torque, and mount rack hardware only after the rails are fully tightened.

Features
Integrated T-Slot Rack Rails The full-length T-slot channels are what make the X4 TS rack-ready. They accept crossbars, bike and kayak carriers, cargo baskets, ladder racks, and roof-top tents, so you can carry gear over the closed cover while the bed stays covered and locked underneath.
Direct Replacement Fit Each kit is cut and drilled to match a specific X4 TS cover, and it clamps to the same factory bed rails as the original set. That makes it a direct swap rather than a universal rail you have to adapt.
Sold as a Matched Pair Rails ship driver and passenger together with the clamp hardware. Rack systems load both sides, so a single rail is not a useful part, and matching a replacement to an existing rail is not something we ask customers to do.
No-Drill Clamp-On Install The rails clamp to your factory bed rails with the included hardware, so there is no cutting, trimming, or drilling. Basic hand tools and the BAK Revolver install sheet are all you need, and most kits go on in twenty to forty minutes.
Matte Black to Match the Cover The rails carry the same matte black finish as the Revolver X4 TS cover and its clamps, so a replacement pair blends with the rest of the system instead of standing out as a repair.
Rails Only, Clearly This is a component kit and we would rather be blunt about it than have you open a smaller box than you expected. You get two rails and hardware. If you need the cover as well, buy the complete Revolver X4 TS instead, which ships with its rails included.

Every rail kit installs the same way. Clamp each T-slot rail to the factory bed rail and tighten evenly, then refit the cover. Follow the BAK Revolver install sheet for clamp placement and torque. If you are replacing a damaged rail, remove the cover first so you can lift the old rail out cleanly.

X4TS At SEMA
A show-floor look at the Revolver X4TS with its integrated T-slot rails, the rack-ready roll-up that carries gear on top while sealing the bed underneath.
Because it is filmed at SEMA with accessories already mounted, it is the clearest look at what the T-slot channel is actually for: hardware slides in anywhere along the rail and clamps down, rather than bolting to fixed points.

Frequently Asked Questions
Straight answers on specs, fit and support
How do I know which rail kit fits my cover?
Use the vehicle selector on this page. The rails are cut to the length of a specific Revolver X4 TS cover, so picking your truck and bed routes you to the matched pair for that cover. If you still have the cover's part number, match that instead; it is the most reliable identifier.
What exactly comes in the kit?
Two rails, driver and passenger, plus the clamp hardware and install instructions. The roll-up cover is not included. If you need the complete cover, buy the BAK Revolver X4 TS, which ships with its rails already fitted.
Why would I buy rails on their own?
Two reasons come up most. A rail got damaged, usually by a low garage roof, a ladder, or a shifted load, and the cover is otherwise fine. Or an X4 TS changed hands without its rails. Either way the rails are the part that carries the T-slot channels, so replacing them restores the rack capability rather than the cover.
What can I mount on the T-slot rails, and how much weight?
The channels take standard T-slot rack hardware: crossbars, bike and kayak carriers, cargo baskets, ladder racks, and roof-top tents, all sold separately. The load limit is set by your rack or accessory maker rather than by the rails, so follow their rating and distribute weight evenly along both sides.
Do the rails require drilling?
No. Like the cover, the rails clamp to your factory bed rails with the included hardware, so nothing is cut or drilled. Follow the BAK Revolver install sheet for clamp placement, and torque everything fully before you load rack hardware into the channels.
Will these rails work on a Revolver X4s or X2?
No. The X4s and X2 use plain side rails with no T-slot channel, and their rail geometry is not interchangeable with the X4 TS. These kits are for the X4 TS only. If you want to add rack capability to a truck that does not have it, the complete Revolver X4 TS cover is the route rather than a rail swap.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
