I am going to put a 2/4 lowering kit on my 2001 Silverado 1500 Reg. Cab Long Box when money allows. I am wondering what the best parts to do this for my specific application would be. I know for the front I could use drop springs, or invest a bit more to get spindles. The rear seems to be a problem. McGaughy's says their shackle/hanger kit is not compatible with the 8 foot box, and to use leaf springs. I looked into a 3/5 kit, but could not find one for a 2wd half ton. Would a shackle/hanger kit from any other company work? What would be the best parts for the front and rear of my truck with the best cross between value and ride quality? Thanks.
