Expertly built by Yukon technicians, it comes shimmed and backlashed to spec, ready for installation directly into your diff housing. Simply bolt on the cover, add fluid, and it’s ready to go.

It features a 5.29 gear ratio with a 30 spline count, and is upgraded with an air-operated Yukon Zip Locker, providing maximum traction and performance capabilities. The assembly also includes a yoke. Key specifications include a 5.29 gear ratio, 30 spline count, and compatibility with Toyota 8” differentials.
