Show original supplier description

The Yukon Muscle Car Limited Slip & Re-Gear Kit, identified by Zumbrota Drivetrain as YGK2312, is engineered to significantly enhance traction and durability for Ford 9-inch differentials equipped with Daytona pinion support. This comprehensive kit provides a 4.56 gear ratio and a 28-spline pinion gear, offering a more aggressive ratio for improved acceleration. It includes a Yukon Trac Loc limited-slip positraction unit, a precision-matched ring and pinion gear set, and all the required bearings and installation hardware for a complete upgrade. The YGK2312 kit is designed to fit a 3.062-inch bore housing. Its coverage extends to classic muscle cars and trucks, specifically mentioning fitment for '65-'73 Mustangs, '60-'70 Falcons, and '67-'79 Cougars. It is also suitable for any vehicle utilizing a Ford 9-inch rear end that has been modified or hot-rodded. By incorporating a limited-slip differential and an upgraded gear set, this kit addresses the need for better grip and performance, particularly in applications where enhanced acceleration is desired. All components are designed for direct integration, assuming the Ford 9-inch differential with the specified Daytona pinion support is already in place.
