Swivel Spline Drive Shaft & Coupler

IT’S A PROVEN fact that the Swivel Spline Coupler Drive Shaft Combo is a better design than the old 10- Spline Internal or External Coupler setups. The reason is it allows the Drive Shaft and Coupler to take misalignment without causing drag or friction like Front Wheel Drive CV Joints, which means more power gets to the Rear Wheels as well as the car is free through the complete suspension travel. Very Simply, Very Clean. This Complete Unit Installs In All Winters Or DMI Rear Ends.
