I can't stand my current rear suspension set up. I guess they are standard springs with a 4" block, maybe 2 and 2? I've honestly not payed too much attention to it since I bought the rig. At any rate it rides brutally harsh. I've got the DIY4X inboarding kit and I'll be purchasing new shocks of course, but I'm trying to decide on 56 or 63 inch springs. The truck sees a lot of pavement, and mostly trails as opposed to rock. Do any of you guys have experience with both setups? Any thoughts or comparisions?
