I usually keep the overdrive shut off..I don't think it would be so bad if the throttle responce wasn't so lowsy...hope that answers your question..

You are correct its not the drive shafts. That info was given to me by David at Northridge4x4... that guy knows his shit. Any questions call him at 360-340-0282. By the way did you Skyjacker lift come with a drop pitman arm. Mine did not. The wholesaler I bought it from told me it was recommended not required. Which is bull because I called Skyjacker and they told me not to drive the jeep without it. Its been on a lift for 2 weeks waiting for the drop pitman arm to come in.

One of the reasons I liked the SuperLift kit is the adjustable track bar comes std. I prefer that to a drop bracket.
