Whiteline Rear Differential Mount Inserts Positive Power Kit Subaru 2008-2026 WRX / STI

Whiteline differential insert bushings work within the voids of the original factory bushing to ensure pinion angles are maintained while delivering an improved gear shift resulting in reduced initial torque loss and greater power transfer to the wheels. These bushings are designed to provide a balance between, but might slightly increase, NVH (Noise, Vibration, and Harshness) over the stock rubber setup.

Features:
- Material = Polyurethane
- Durometer Rating = 85
- Mounting Hardware NOT included - reuses OEM
- Color = Black
- Positive Traction: Reduces initial torque loss and improves power transfer to the wheels by restricting rear differential movement.
- Durable Material: Engineered from high-quality "Synthetic Elastomer" (polyurethane) that is resistant to oil, grease, ozone, and weather.
- Performance Upgrade: Improves handling and gives a firmer, more direct feel to gear shifts.
- Easy Installation: Designed to work within the existing original factory bushing, minimizing the need for specialized tools.
- Improved Longevity: Includes internal grease reservoirs and molybdenum desulphated (LM) based grease to extend the life of the bushings
