Sooooo I bought a 2/4 Rough Country lowering kit for my 2017 GMC Sierra. Rough Country said this kit would work. When I got it I had it installed, after being called several times about fitment issues I went to the garage to see what was up. The cancer plates wouldn't work with the Camber bolt, I called Rough Country they said to use the 2014-15 Camber bolts, they worked. So the truck is lowered in the front 2".
Moved to the back of the truck, I watched the tech remove the factory rear components and start assembling the new rear. He hung the new rear hangers, and installed the shocks that came with the kit ( removing the factory hangers were a chore..popping rivets) he bolted everything up and even installed the 2 shims that came to mount under the transmission. When the truck came off the lift it was still high in the rear. it was supposed to be an even drop but the front is low and the back is too high!!! I called rough country and they were saying that kit would not fit and they won't make one for the 16,17,18 and 19 trucks!!! But I told them you sold me kit that u said it would fit I even have the sticker off the box that said it was for a 2014-18 truck!! I drove the truck home and at 75mph it has this violent vibration.... so no discussion needed if you see below thats the outcome of a 2/4 drop by rough country. I measured the front from middle if wheel to the fender and was 18inches both sides, I did the rear it was 21.5 inches. thats 3.5 inches difference. so my front is actually 3.5 instead of 2 inches. now I need to get the back down lower. can someone recommend a complete REAR ONLY! 3/6 inch adjustable lowering kit that would give me an even look and a non violent vibration ride?????
