I Bought the Bilstein 5100 Series Adjustible front shocks my 09 Silverado. I also bought the rear 5100 Series shocks that will provide for an extra inch of rear lift. My question is, which lift block should I buy that will only raise the rear of my truck 1 inch? Is there one? Most I find are going to lift my truck 1.75 inch from where it is now. If I lift the rear more than an inch will it harm my rear shocks? -Thanks!
