Looking for information on Skyjacker lift kits. Contenplating using the Skyjacker 4. 5" classII double flex system with softride rear leaf springs. Just wanted to hear from others that installed simular lifts on their trucks. How do they like it? Did you install it yourself? if so was it complete and were the instructions acurate? How do you like the lift now that it is installed? Any problems? Would you do it again? Thanks
