Good Morning, Jeff! I don't have dual shocks on my Rover yet, but do plan to as time & $$$ permit. I do have OME springs on a couple of my trucks & have great results w/them. 3" of lift will require more that that, though. Do you still have your rubber Rotoflex on your rear driveshaft? If you do, save yourself some $$$ now and replace w/a u-jointed driveshaft as the Rotoflex/Lift don't mix! Yeah, I thought I could get away w/it too, so I did my rear driveshaft after the springs. I should've done it first! Extended brake lines will also be needed, and well worth it, overall brake function seems better. there are other issues as well that slip my mind for now, but I'm sure someone will give more info. How long have you had your D1? I really like mine, it serves me well! Thank You, LRW.
