TeraFlex NP231 short shaft kits, or slip yoke eliminators, with new heavy-duty shafts, are engineered to withstand the 50 percent increase in torque generated by the extreme reduction of the Tera Low231 gears. These kits also eliminate the need to lower the transfer case in most cases by increasing the rear driveshaft length by 4 in. They include a larger output bearing and rear housing.


Questions & Answers Ask a Product Question

We are putting an 8" lift on a 96 XJ and considering installing this SYE. Once it is installed will the stock drive shaft still work or will we need a new one?

Asked by JOE on May 20, 2018


Stock will not work. Stock has a slip yoke on it, a sye will eliminate that yoke,and the shaft will be bolted to the yoke of the transfer case. The shaft itself will slide out and into itself,and not into the output shaft
