When installing a long travel suspension system and/or crossover steering the front drive shaft spline is just not long enough to get the job done. The kit allows a full 8″ of slip travel. This is not some cheap rip off like other companies offer. This is a very high quality drive line kit that is Made in Japan!
Includes a new high quality Japanese-made U-Joint, which is the same u-joint as stock 1984-1995 Pickup & 4Runner applications. Extra u-joints for trail-spares available here.

To install, cut the tube from your drive shaft and replace with a length of .095 or .120 wall tubing. Set up the drive shaft so that you have 3″ of compression and 5″ of extension at ride height.
