Is that the original Airbar version?... The piece that attaches to the frame rail looks like it has a pretty small "contact patch" to the rail... That's a lot of force on a small area... I think the newer version has a much bigger contact surface that spreads the load force out over a larger section of the rail
The Airbar in my Cuda has the UCA bar in the middle of the frame rail attachment section... Not at the edge like your picture...
