hey man im gonna get the ball joint spacers to to get a smoother ride, anyways for the back what i did was got a coil spring out of a late 90s jeep cherikee and cut it down to 10 inches. i compressed it and put it between the bumpstops on the back leafs, it sounds bad but thats how i got rid of my "saggy rear end" they act as over load springs. ill get somepics on here for you to see my madnes. but it was a 3in lift for 20 bucks i was happy, plus its kinda bouncy for when ya need it ;-D
