Just installed new front leaf springs and lowering kit from patricks, the original front springs were eight leafs, patricks are four,he also supplies new shackles bushings and front shocks. the rear is just two inch lowering blocks and u bolts .the results are two inchs lower all around, nice smooth ride,no bounce, better cornering,and overall handling. plus my old bushings and eyes on the leafs were worn egg shape,with new bushings no more sweaks in the front end . no problems with installing front springs and bushings took little over two hours ,this was on my 51 chevy 3100.
