I have a YJ that we shifted the axle back on and was wondering if there were any shorter leaf springs I can use. That way it would stretch give the driveshaft a better angle. I believe the YJ springs are 42.5
A lot of guys run the XJ springs in the rear. I think it gives you 6 inch stretch. I have a set to throw on my CJ, but just haven't got around to it yet.
