Sorry to revive an old thread but this one has a ton of good info but I'm still curious:
I've got 550lb springs and have 6 threads showing on pass side and 14 showing on driver side. I've more on the driver side to fix the lean.... but it still has a lean. I'm going to add a spacer to the rear on the driver side to see if that helps. Mostly curious if I go up to 600 lb springs, how much preload should I expect to achieve the same ride height?
Added weight: Hidden winch mount with 10k winch, gp 27f battery, rtt, sliders, aluminum front, trans, tcase skids, steel gas skid.
