Yukon Gear & Axle YDATLCF-529YZL Dropout Assembly Toyota 8" Reverse Rotation Front Diff w/Zip Locker 30 Spline 5.29 Ratio

The Yukon Gear & Axle YDATLCF-529YZL is a fully assembled dropout assembly (third member) for the Toyota 8" reverse rotation front differential, upgraded with an integrated Yukon Zip Locker for on-demand, air-operated traction control. Built by expert Yukon technicians, this unit arrives completely shimmed and backlashed to specification — drop it into your differential housing, bolt on the cover, add fluid, and you're ready to go.

The Yukon Zip Locker delivers selectable locking performance on demand. Air pressure engages a clutch against a splined gear, locking the spider gears for 100% axle lockup when traction is needed most. With the flip of a switch, air pressure releases and a return spring disengages the clutch, returning the differential to open operation for normal street driving.

• Fully assembled dropout — shimmed and backlashed to spec, ready to install
• Yukon Zip Locker integrated — air-operated, on-demand 100% differential lockup

This dropout assembly is the ideal solution for off-road builds requiring a reliable, pre-built third member with integrated locking capability. The Yukon Zip Locker's proven design provides the performance of a premium air locker at a competitive price point, making it one of the most capable and cost-effective upgrades available for the Toyota 8" reverse rotation front axle.
