Hey guys new to group and I am finding much confusion with how to go about lifting my 1972 GMC Jimmy it is stock and running 33" tires now I want to do a 6" Suspinsion Lift by tuff country. but I dont know what the best way is. should I go 6" lift springs in the front and a 4" shackle flip in the back with a 2" spring lift or a 6" spring lift in the back also. what else will I need to avoid developing alot of vibration in the front end. and will my pinion angle need to be adjusted. I thought I had this figured out but now I am not so sure. and can I do this myself I am an average to above average do it yourselfer mechanic. I am also wanting to put on a 1" body lift and want to know if that is real hard to do. and if shackles are the way to go who makes the best shackle flip kit. thanks in advance for any kind of help you can give I have realized I dont know as much as I thought. I will be posting pic's soon.
