Each component is rigorously tested in Yukon's in-house quality labs to ensure dimensional accuracy and proper fitment.

The included Trac Loc limited-slip differential enhances traction by transferring power to the wheel with the most grip, making this kit ideal for street performance, off-road applications, and track use. The 3.00 gear ratio provides excellent highway cruising characteristics while maintaining strong acceleration capability.

Note: Professional installation recommended. Proper setup and break-in procedures must be followed to ensure optimal performance and longevity. Limited slip additive or appropriate friction modifier must be used with differential oil.
