The UPR lowers just have heims at the front (body side) point. The rear (axle side) is a solid aluminum bushing. The uppers are double adjustable with left & right threads so there's no need to take the control arms down to adjust them. The anti-roll bar links also have left/right threads for on-the-car adjustment.

I'm running a four-cylinder spring in the rear with about 1-1/2 coils chopped off. I've got 10-way AVO shocks on the rear too.
