Hey guys.. thought it would be a good idea to join a forum so I can find answers to my many questions! I have a 2007 Silverado 1500 crew cab 2wd new body style and I would like to lift it 4.5 inches. The question is how high can I go before I would need new shocks? Many lift kits come with the choice to have shocks included or not at all. Any input would be helpful, thank you!
