I would be willing to bet that this might be his problem. The installer that installed his kit probably did a poor job and didn't re route lines and cables. There is alot more involved than just throwing these kits in than people think, proper clearances, etc. Bds is top of the line and i've used lots of there kits with zero issues and on some of my trucks i've pounded on them pretty bad, but i've since out grown those days.
