Yukon Gear YGK2019 is a complete rear differential re-gear and limited-slip package for compatible GM 8.6-inch applications. The kit combines a 4.56:1 ring-and-pinion gear set, Yukon Master Install components, a 30-spline Yukon Dura Grip clutch-style limited-slip differential, and axle bearings and seals under one part number.
This Pro Kit uses Timken bearings in the installation package and includes the small parts needed for differential setup and rebuilding. The supplied carrier uses 3.062-inch outside-diameter carrier bearings and is intended for compatible applications with a 10-bolt rear cover and 10-bolt ring gear.
The included Dura Grip is a rebuildable clutch-type limited-slip differential. Combined with the 4.56 gears, installation components, axle bearings, and seals, YGK2019 provides a comprehensive package for ratio changes, differential rebuilding, and replacement of worn rear axle components.
