I have a rugged ridge sye, and a cut down Cherokee front driveshaft. It works well and saved some cash.
The driveshaft was 35 from a pick n pull, and the driveshaft shop charged me 90 or so to cut it down.
the the sye install was much easier than I expected. I left the transfer case in the jeep.
if you go with a super short sye you'll end up with an electronic speedo sensor, so simply changing the gear to offset larger tires will no longer be an option
