Yukon Gear & Axle YDATV6-456YZL Dropout Assembly Toyota V6 Rear Differential with Zip Locker 30 Spline 4.56 Ratio

The Yukon Gear & Axle YDATV6-456YZL is a complete, fully assembled dropout (third member) assembly built specifically for the Toyota V6 rear differential. Each unit is assembled by expert Yukon technicians and arrives fully shimmed and backlashed to factory specification, ready to drop straight into your differential housing — no setup required.

This assembly is upgraded with the Yukon Zip Locker, an air-operated selectable locker that delivers on-demand maximum traction when you need it and returns to open differential behavior when you don't. When pneumatic pressure is applied, a locking collar engages and locks both axle shafts together, creating equal power distribution to both tires. When disengaged, the differential functions like a standard open unit for comfortable, predictable street driving.

Zip Locker Construction: The Zip Locker is engineered with a forged steel case and 4320 chromoly steel internals for superior strength and durability across all terrain types — from sand and mud to rock and boulders. It is compatible with most vehicle air delivery systems and compressors.

• 4.56 gear ratio for aggressive crawling performance

The Yukon Zip Locker is backed by Yukon's industry-leading warranty — six years against manufacturing defects, including coverage for collaterally damaged parts and associated labor, with up to $2,000 in coverage for the first two years. This dropout assembly delivers a straightforward installation experience: install the third member, bolt on the diff cover, add fluid, and go.
