Frequently Asked Questions

Do I need to drill holes or modify the truck frame to install this?

No. This mounts at factory points — no drilling needed. You'll bolt directly into existing frame attachment locations.

Will this interfere with the extended cab doors when they open?

It's engineered for extended cab door and window clearance. Test-fit before final tightening to confirm clearance on your specific vehicle configuration.

What hardware do I need to bolt this on?

The assembly includes mounting points, but fastener spec isn't confirmed in the product data — check your vehicle's service manual for the correct bolt size and torque spec for frame attachment points.
