I just bought this 98 Yukon and I am trying to figure out what lowering suspension parts I have installed on this truck. I have looked for stock ride height measurements and have found a couple references to a measurement of 21.25 " from center of wheel to bottom of fender. Is this measurement pretty close for a factory height? Also the pics below are of the rear leaf springs which have a bend in the longest leaf as they return to the shackle to lower the truck but i haven't seen anything like this online. Any ideas who makes this rear leaf? I like the look of the truck but need a little more ride ride height but I dont want to go stock. Thanks
