The U bolts were about 1/2" too short.
I had to purchase longer U Bolts locally for 40.00 because yours were too short by about 1/2". The nylon lock nuts liked about 3 threads getting into the nylon locking ring at head of mounting bolts. So, considering I had to pay 40.00 more locally, after tearing down truck, so I could get back on road, they were not a deal. Very disappointed with Belltech. I have purcased half dozen or so products from their name brand and never had problems before.
Spent 16 hours under my MKV GTI on a lift installing these with the Eibach Pro Kit springs and Eibach Sway Bars and Whiteline Endlinks. All great quality and stiffened up my ride while the FSDs kept me comfortable as well as tI'd to the road aND tight around be ds aND corners. Hitting an on ramp, you feel them tighten up as those lateral Gs start to rip your face off but they hold.The FSDs really are amazing and they are a steal on this site. If AutoEverything doesn't have it, you don't need it!
