Description

The Yukon Muscle Car Limited Slip & Re-Gear Kit is a comprehensive differential upgrade package designed to significantly enhance traction, durability, and acceleration for vehicles equipped with a Ford 8.8” differential. This kit integrates a Yukon Dura Grip positraction limited-slip differential (LSD) and a high-performance ring and pinion gear set, allowing for a more aggressive 3.73 gear ratio. Key components of this kit include the Yukon Dura Grip LSD, specified with 31 spline compatibility, a 30 spline pinion gear, and a 10 bolt ring gear. It also includes all necessary bearings and installation hardware for a complete setup, along with 2.25” OD axle bearings. The kit is compatible with a broad range of vehicles, including the '79 to '14 Mustang, '79 to '97 Cougar, and 28 other models, as well as any custom builds utilizing a Ford 8.8” differential. This re-gear kit offers an opportunity to not only upgrade the differential's traction capabilities but also to optimize for acceleration with the included 3.73 ratio. This change in gear ratio can provide a noticeable improvement in responsiveness and overall performance for muscle car applications.
