Description

Yukon dropout assemblies are built by expert Yukon technicians and come complete, properly shimmed and backlashed to spec. 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 Sure-Grip/Powr-Lok limited slip differential, a four-spider-gear design that improves torque bias and traction for maximum performance.
