Features
- Sold as a Set of Two: Both side rails in one box. BAK sells this component only as a set of two, fully assembled.
- Fully Assembled Rails: Each set comes with the inner and outer rails, mounting plate, spring actuators and locking levers already put together.
- Shims Where Needed: Two spacer shims and eight angle shims are included when your truck needs them to sit the rails square.
- Clamps Sold Separately: The set does not include clamps. BAK's rail sheet mounts the new rails with clamps at the front, middle and rear of each rail.
- Made for One Truck: Each rail set is vehicle specific, matched to one truck and bed length, like the cover it goes under.
- X4ts T-Slot Rails: These are the rails for the Revolver X4ts, the version with T-slot rails for racks and cargo accessories, not the plain X4s or X2 rails.
Description & Fitment
This BAK replacement T-slot rail kit replaces both rails under a Revolver X4ts cover on Chevrolet and GMC trucks with the 6'6" bed. It fits the 1988-1998 C/K 1500, 1988-2000 C/K 2500 and 3500, 1999-2013 Silverado and Sierra 1500, the 2007 Silverado and Sierra 1500 Classic, 2500 HD Classic and 3500 Classic, the 1999-2014 Silverado and Sierra 2500 HD and the 2001-2014 Silverado and Sierra 3500 HD. Both sides come factory assembled with the inner and outer rails, mounting plate, spring actuators and locking levers in place, with shims where needed and clamps sold separately. These are the T-slot rails that make the X4ts rack-ready, and the 2014-2018 Silverado 1500 takes rail set RAILS-80121RK instead.

Frequently Asked Questions
Will this fit my 1988-1998 Chevy / GMC C/K Pickup 1500?
Yes, if it has the 6'6" bed. It fits the 1988-1998 Chevy / GMC C/K Pickup 1500 and 1988-2000 Chevy / GMC C/K Pickup 2500 and 3500 and 1999-2013 Chevy Silverado / GMC Sierra 1500, 2007 Chevy Silverado / GMC Sierra 1500 Classic, 2500 HD Classic and 3500 Classic, 1999-2014 Chevy Silverado / GMC Sierra 2500 HD and 2001-2014 Chevy Silverado / GMC Sierra 3500 HD. Measure along the bed rail from the bulkhead to the closed tailgate, check the fit notes above, and if you are unsure, send us your VIN and we will confirm.
Will these rails fit my Revolver X4s?
These are the X4ts T-slot rails. BAK lists separate rail sets for the X4s and the X2, and for BAKFlip covers, so match the rail set to your cover model as well as your truck.
Does the set include clamps?
No. BAK lists clamps as not included (sold separately). BAK's rail sheet installs the new rails with clamps at the front, middle and rear of each rail.
How do I make sure I order the right rails?
Each rail set is made for one truck and bed, so check the part number and your bed before you order, or send us your VIN and the part number on your current cover and we will confirm.
Do I have to take the cover off to replace the rails?
Yes. BAK's rail sheet starts with the cover off the truck and the old rails removed, then the new rails clamp on and the cover goes back on and is squared up.
Are X4ts rails the same as X4s rails?
No. BAK lists separate rail sets for the X4ts (with the T-slot) and the X4s, at the same truck and bed. Order the set that matches your cover.
