Does the skyjacker lift include Skyjacker shocks. I need to replace rear shocks and there is a good deal on 4 skyjackers (front and rear). I dont do any off-roading - truck is 96 2WD with 4" fabtech lift in front. Most radiacal I might get is jumping curb to avoid traffic. ThanksI have a 2001 Chevy Silverado 1500 with a 6inch Skyjacker suspension lift Is there anything else I can put on it to bring the rear up 2 inchs or more?
