NP231 Heavy Duty SYE Kit

Stock Jeeps have a slip yoke style output shaft at the rear driveline. This stock design is not conducive to off road use nor the steeper operating angles caused by suspension lifts. To ensure smooth and durable driveline operation, you should convert to a fixed yoke output and install a rear CV driveshaft.

We highly recommend a SYE on all lifts over 3.5". This Heavy Duty SYE kit includes a new output shaft that is larger than the stock unit for extra durability. No core required.
