Due for a new set of tires and I'm pretty much set on the TSR 315/75-16. Based on my research it looks like I'm headed for 4" lift due to clearance reasons, and I've looked at adding blocks in the back and a bracket in the front. Any opinions about whether I should buy a kit or piece it together with individual parts and maybe salvage springs added up front. Any concensus about who has the best quality kits/parts based on experience.
