imo, dont get the coil spacers(at least not the big ones) i recently installed them on top of my 3 inch rustys coil springs and the ride is really stiff. and has no give especially on the rutted up roads here in SE mich. get full coil springs they ride much better. i just ordered a pair of 4.5 -5 inch front springs so i can take them pucks out. as for the rear like everyone said..blocks are not cool. get springs. my buddy used, s-10 springs and got some nice lift out of em w/ extended shackles.just my .02 cents...
