I have a BDS 2.5" leveling kit on my 07 chev 1500 classic and it works really good. I have just over 100,000km on the kit and 176,000km on the truck. At 160k i had a pitman arm, idler arm and one inner tie rode replaced and i was told that it was regular wear and tear, nothing to do with the leveling kit. I really can't complain with that many km's and thats all the wear and tear.
