i am saving for an sye/cv shaft. trying to make this work till then. thanks in advance.

I don't think so, I talked to RE about this a while back, and they told me that a longer slip yoke will not correct the binding. The part you have pictured is actuaily the same slip-yoke used on a stock YJ, you would only use this if you had a problem with the rear driveshaft popping out from excessive articulation. Try longer shackles, they tend to help pivot the pinion angle up a degree or two. Im currently running Ram 1500 shackles which are about an inch longer than a XJ shackles, they are slightly wider at the bushing end, but you can grind them down. I also use a 1" t-case drop.

thanks. i'll try a little longer shackle. i'm open to any other ideas you guys have. thanks again.
