I like to do general trail off roading, with a little bit of rock crawling. Current I run a 6" lift with 35 inch tires. I have uprgraded to a 14 bolt FF in the rear, and current upgrading to crossover steering in the front with a Dana 44 modified for 8 lugs. I have 6" blocks in the back but I want to get rid of those. What is a good height to modify my rig? I was thinking of leaving the springs in the front the give the 6 inch lift untouched. Then doing a shackle flip in lift in the back to gain 4 inch then install some 2 inch blocks. Is there a better way to get 6 inches in the back? SHould I go lower or higher? 84 K5 or K10 Blazer not sure how to tell the difference.
