Jeep JK Differential Locker - Rear - Yukon Gear & Axle - Zip Locker - `07-`17

Jeep JK Differential Locker - Rear - Yukon Gear & Axle - Zip Locker - `07-`17 is an air-operated, on-demand locker that lets you switch from an open differential to full lockup when you need maximum traction. Designed for Jeep JK non‑Rubicon rear Dana 44 housings, it gives selectable traction for both trail and street use.

The Yukon Zip Locker engages 100% axle lockup with an air signal, so you control when to lock and when to run an open differential for normal driving. It is assembled in the USA, includes new carrier bearings, and is drilled for 1/2" ring gear bolts. This unit fits NON‑Rubicon JK rear housings only and accepts 30‑spline axles. The locker works with a variety of air delivery systems (compressor sold separately) and ships with Yukon’s Zip Locker warranty coverage: a six (6) year warranty and additional coverage for collateral damage and associated labor up to $2,000 for the first two (2) years.
