Revolver X4TS Replacement Rail Set | Bak Industries Parts
Our X4TS rail set is engineered to restore factory-grade fitment and weather sealing on Revolver X4TS tonneau covers. Each rail is precision-extruded from aluminum with integrated weather seals that lock out water, dust, and road debris.
Designed for owners who need to replace damaged rails or upgrade an older Revolver X4 installation, this set delivers the same tight tolerances and corrosion-resistant finish that came with your original cover. The powder-coated surface resists UV fade and maintains a low-profile aesthetic across all bed lengths.

Why replace your X4TS rails
Rails take the most punishment of any tonneau component. Cargo shifts during hard braking, tie-down straps apply lateral pressure, and winter ice buildup can crack seals or bend aluminum over time.
Replacing worn rails restores panel alignment, eliminates water leaks at the bed edge, and brings back that tight snap when you close each section. If your cover no longer sits flush or you see daylight along the bed rail seam, new rails solve the problem without replacing the entire cover.
Installation and compatibility
This rail set fits all Revolver X4TS tonneau covers manufactured from 2015 forward, across Ford F-Series, Chevrolet Silverado, GMC Sierra, Ram 1500-3500, Toyota Tundra, and Nissan Titan bed platforms.
Installation requires no drilling. Remove the four clamps securing each original rail, lift the old rail out of the bed channel, drop the new rail into place, and re-tighten the clamps to factory torque specs (18 ft-lbs). Total installation time averages 30 minutes with basic hand tools.
Material construction and finish
We extrude every rail from 6061-T6 aluminum, the same alloy used in aerospace structural components. This grade offers a 35,000 psi tensile strength, meaning the rail resists bending under cargo loads up to 500 pounds distributed across the cover surface.
The powder-coat finish is applied after extrusion and cured at 400°F for chemical bonding to the aluminum substrate. This process creates a finish layer twice as thick as conventional paint, preventing chip and peel even when cargo scrapes across the rail edge.

Common questions about X4TS rail replacement
Yes. Our rail set is compatible with all Revolver X4TS installations on 2022-2024 Toyota Tundra beds, both 6.5-foot and 8.1-foot configurations. Rails are shipped at full bed length and trim to fit during installation if you have an aftermarket bed cap or liner that shortens the usable rail channel.
If you have a 2014-2021 Tundra, verify that your cover is the X4TS model (four-panel hard folding with integrated seals) rather than the older X4 or X4S. The X4TS uses a different clamp design and rail profile.
We sell rails individually if only one side is damaged, but we recommend replacing both rails together to maintain even clamping pressure and seal compression across the bed.
Mismatched rail wear can cause one side of the cover to sit slightly higher than the other, creating a cosmetic gap and potentially allowing wind noise at highway speeds. Replacing both rails guarantees symmetrical fitment and eliminates any chance of visual mismatch between old and new powder-coat finishes.
Yes. The rail set is compatible with both drop-in plastic liners and spray-in bedliner coatings. If you have a drop-in liner, you may need to trim the liner's top edge slightly where the rail clamps contact the bed wall—this is standard for any tonneau installation over a drop-in liner.
Spray-in liners require no modification. The clamps compress the liner material and create a secure mount without additional hardware.
Common signs include visible bends or dents in the aluminum rail body, cracks or hardening in the weather-seal rubber, water leaks along the bed edge after rain, or cover panels that no longer align flush when closed.
If you see daylight between the rail and the bed wall, or if the cover bounces or shifts during highway driving, your rails have likely lost clamping tension or sustained structural damage. Replacing rails before seal failure becomes severe prevents water damage to cargo and keeps the cover operating smoothly.
Yes. We sell replacement EPDM seal strips separately for customers who want to refresh seals without replacing the entire rail. Seals press into the rail channel by hand and require no adhesive or special tools.
However, if your rail itself is bent, cracked, or shows finish wear, replacing the full rail ensures you get a fresh seal and structural integrity in one step.
You need a 10mm socket wrench or adjustable wrench to remove and reinstall the clamp bolts, and a torque wrench if you want to hit the recommended 18 ft-lb spec (though hand-tightening to snug resistance works for most installations).
No drilling, cutting, or special truck-bed tools are required. The rails drop into the existing bed rail channel and secure with the same clamp locations your original rails used.
This rail set is designed specifically for the Revolver X4TS model, which features a thicker panel design and integrated weather-seal channels introduced in 2015.
If you have a Revolver X4 or X4S (older models with external seal strips or different clamp spacing), you need the corresponding <a href='/parts-accessories/revolver-x4s-rails/'>X4S rail set</a> or <a href='/parts-accessories/mx4-rail-set/'>MX4 rail kit</a> depending on your cover's generation. Check your cover's label on the underside of the front panel to confirm the model number before ordering.
