All you do is install the third member into your diff housing, bolt on the diff cover, add fluid, and roll. This unit features a nodular iron case which improves rigidity and power handling, reducing deflection for consistent gear contact and a long service life. This assembly is upgraded with a Yukon steel spool for maximum traction and performance.
