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 solve this problem and ensure smooth and durable driveline operation, use product from Rubicon Express. A must on all lifts over 3,5". Drill and tap included for easy installation. Drive flange is machined from solid stainless steel for extreme strength and corrosion resistance.
