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 β check your vehicle's service manual for the correct bolt size and torque spec for frame attachment points.
