I installed some TJ coils in the rear of my '84, which had tired stock springs. I got 2" of lift as well. I jacked my truck up by the frame and let he rear axle droop and was able to "install" the springs without any tools. I haven't done any serious off-roading since the install, eight months ago, but I have hit some large speed bumps and driven over some curbs without any problem. One problem with a 2" lift and stock shocks is that it puts your shocks at their upper limit, so they don't have any room left to extend, which may be part of the cause of your harsh ride on bigger bumps (which I have as well). I'd like to hear the experts recommendations on a good shock for this set-up. -- Matt
