I have 2'' of body lift in my 2000 Chevy Silverado. I want to buy more 2'' lift blocks and longer bolts and make it 4''. Can anyone tell me if I can get by with just a steering extension and a gas filler neck. Iv done tons of 3'' body lifts and haven't extended anything except raise the bumpers up. I also know they don't make a 4'' body lift because of safety reasons so no need to tell me that lol. Just wondering if anyone has done this and what problems they came across while doing it.
