Today I replaced my rear end lift. I went with OME 891s and Icon v2s. I put 30mm of spacers on the driver side, and 15 on the passenger side. That about leveled it out side to side. The measure from ground to fender is now 37" +- 1/4" on each side. With the 890s I was at 35 3/4 on the driver and 36 1/4 on the passenger. I made the change to try and get my front to back level with my full expedition weight (RTT+Hilift+4 rotopacks), but the rear is still about 1/4-1/2" lower than the front.

The Icons definitely feel softer than the OMEs, we'll see how they off road. I did Fins and Things with my RTT and felt the old setup was bottoming out, yet was fairly stiff on washboards.
