Diff Positive Power Kit

The Whiteline Performance Diff Positive Power Kit (model KDT927) is a premium differential bushing upgrade designed specifically for Subaru Legacy and Outback models from 1999 through 2019. This kit includes a pair of polyurethane and steel bushings that effectively reduce unwanted differential movement during acceleration, cornering, and load transfer, enhancing handling response and minimizing wheel hop.

The bushings are constructed from durable polyurethane with zinc oxide plating, providing superior longevity and compliance compared to factory rubber bushings, which can degrade over time. The steel reinforcement cores ensure structural integrity under high cornering loads, while the polyurethane elastomer absorbs vibrations without the harshness associated with solid metal-to-metal contact. This dual-material design allows for a factory-friendly installation that typically requires no modifications.

Subaru enthusiasts, performance drivers, and shop technicians will find this kit's direct bolt-in compatibility with Legacy and Outback platforms beneficial for improving chassis control without sacrificing ride quality. While installation is straightforward for those with basic suspension service experience, it is advisable to seek professional alignment to ensure optimal performance.
