Show original supplier description

The Yukon Gear SL C8.25-29 USA Standard Spartan Locker is engineered for Chrysler 8.25-inch, 29 spline corporate axles. This mechanical locker replaces the factory spider gears and thrust washer with its own locking gears and a revolutionary spring-loaded pin design, simplifying installation. It is constructed from 9310 steel for enhanced strength over stock components. This locker provides 100% lockup traction, delivering superior performance and grip in soft or off-road conditions by applying equal torque to both sides. This Spartan Locker is specifically designed for fitment on 1997-2001 Jeep Cherokee (XJ), 2005-2010 Jeep Grand Cherokee (WK), and 2002-2012 Jeep Liberty (KJ & KK) models equipped with the Chrysler 8.25" axle and 29 spline axles.
