Stock Jeeps have a slip yoke style output shaft at the rear driveline. This design is not conducive to off road use nor the steeper operating angles caused by suspension lifts. To ensure smooth and durable driveline operation, convert to a fixed yoke output and install a CV driveshaft (style RE1898). A must on all lifts over 3.5". This kit requires the modification of your stock output shaft. Drill and tap included for easy installation. Drive flange is machined from solid Stainless Steel for extreme strength and corrosion resistance.

5 out of 5 stars

Easier than you think

The fact I had to shorten my output shaft scared me but it went very well. I used a cut off wheel and ground it flat. Check frequently with a small square to get the end flat. Drilling and tapping the center hole was far easier than I thought. It really doesn't have to be exactly centered because it is just a keeper. The rest is very easy. I did it on a NP 207 and it worked great.
