I had a shop install one on my truck a few months ago, toytec coils , 5100's and 1.5"aal with a dif drop and they didn't have to do anything to brakes, 2013 reg cab
Good stuff. You use less preload to lift the truck so you get a better ride than using 5100s with the stock coils. Search anywhere and people are always more than happy with 5100s.
