Constructed from hardened steel and finished with a polished surface, this gear set features dual ratio configurations: 4.12 gearing (5.91 and 2.87 options) and 4.86 gearing (6.97 and 3.39 options), allowing drivers to select the optimal ratio for acceleration, top-end speed, or fuel economy demands. The 10-spline hub design ensures secure engagement and reliable torque transfer under extreme load conditions typical of racing and performance applications. Winters' precision manufacturing and heat-treatment processes guarantee consistent performance and extended service life, even during repeated quick-change cycles and high-stress acceleration events.

This gear set is ideal for owners of Winters 8500-series differentials who operate multiple vehicles or compete across varied track layouts requiring frequent ratio adjustments. Installation is straightforward for experienced technicians familiar with quick-change differential systems; proper carrier setup and bearing preload verification ensure optimal meshing and quiet operation. The compact 5.05 x 1.95 x 8.95-inch profile integrates seamlessly into OEM and aftermarket 8500-series housings, making it a practical upgrade for serious racers seeking performance flexibility without expensive component swaps.
