Airplex Bed Rail Mounting Kit
Replacement J-clamps and mounting hardware to restore a tight, no-drill fit on your bed rail. A loose or corroded clamp is the most common reason a cover starts to shift slightly — this kit fixes that without replacing the whole cover.
Shop This KitOverview
Every Airplex tonneau cover mounts to the bed rail using a set of clamps rather than drilling into the truck. Over years of use — especially in areas with road salt or heavy rain — those clamps can loosen slightly or start to corrode at the contact points. This kit gives you fresh, corrosion-resistant clamps and hardware sized to match the mounting system used across the Airplex lineup.
Re-torquing or replacing worn clamps restores the same tight, no-drill mount your cover had on day one, without needing to remove the cover from the truck entirely or buy a new one.
What’s Included
J-Clamps
A full set of replacement J-clamps sized to grip the standard factory bed rail profile.
Mounting Bolts
Zinc-coated bolts and washers that resist corrosion at the clamp contact points.
Torque Guide
A printed guide with the correct torque spec so clamps seat evenly without over-tightening.
Rail Padding
Protective rubber padding for the clamp contact point, preventing scratches on the factory rail finish.
Checking Compatibility
This kit is sized for the standard J-clamp mounting system used across the Airplex hard folding, soft roll-up, retractable, low profile, and hinged cover lineup. If you’re not sure which mounting hardware your cover uses, check the model name on your original packaging or email us your truck and cover style and we’ll confirm before you order.
How Installation Works
- Loosen the old clamps. Remove the worn or corroded clamps from the bed rail.
- Clean the rail. Wipe down the contact point so the new clamps seat cleanly.
- Position the new clamps. Set the new J-clamps at each original mounting point.
- Torque to spec. Tighten each clamp evenly to the spec listed in the included guide.
- Recheck the fit. Confirm the cover sits square and doesn’t shift when pressed down.

Frequently Asked Questions
How do I know if my mounting hardware needs replacing?
If the cover feels slightly loose, shifts when pressed, or the clamps show visible rust or corrosion, it’s a good time to replace them. Clamps typically last years but corrode faster in salt-heavy climates.
Will this fit my specific cover style?
This kit is sized for the standard J-clamp mounting system used across the Airplex hard folding, soft roll-up, retractable, low profile, and hinged covers. Email us your cover model if you want to confirm before ordering.
Do I need to remove the whole cover to replace the clamps?
No. Clamps can typically be replaced one at a time while the cover stays mounted, as long as you support the cover while each clamp is loose.
What tools do I need?
A basic wrench or socket set is all that’s needed — the included torque guide tells you exactly how tight to go.
