i have the the BDS 4" short arm lift. i love it. no complaints at all, i'm in a JK, not a JKU but still. thought i bent the pitman arm wheeling... called BDS, had another pitman arm in 3 days..
turns out i just bent the drag link... lol
but seriously. those guys have fantastic customer service. believe in their product. i try to wheel my rig when ever i have coin and time...
i have nothing but good things to say about BDS
