Yukon Gear & Axle YDAT8-529YZL Dropout Assembly Toyota Differential w/Zip Locker Ratio Spline - 8 5.29 30

The Yukon Gear & Axle YDAT8-529YZL is a fully assembled dropout (third member) for the Toyota 8" rear differential, built to deliver a hassle-free, performance-ready installation. Each unit is assembled by expert Yukon technicians and arrives completely shimmed and backlashed to factory specifications — simply drop it into your differential housing, bolt on the cover, add fluid, and drive.

This assembly is upgraded with the Yukon Zip Locker, an air-operated locking differential that gives drivers on-demand locking capability at the push of a button. The Zip Locker engages and disengages via the vehicle's onboard air system or an auxiliary air compressor, making it ideal for off-road use where maximum traction is needed without sacrificing everyday street drivability.

Key Features:

• Gear Ratio: 5.29
• Spline Count: 30 spline
• Application: Toyota 8" differential
• Locker Type: Yukon Zip Locker (air-operated, on-demand locking differential)
• Includes yoke for direct bolt-on installation
• Fully assembled, shimmed, and backlashed to spec — ready to install

Whether you're building a dedicated trail rig or upgrading your daily driver's axle for more aggressive terrain, the YDAT8-529YZL delivers a premium, plug-and-play solution with performance locking capability built right in.
