Overtake Rear Differential Bushing Insert Kit 2008-2026 WRX / 2008-2021 STI

The rear differential is a critical component of Subaru’s AWD system, yet the factory rubber mounts are engineered primarily for comfort. Under hard acceleration or aggressive cornering, those soft bushings allow excessive differential movement, wasting energy that should be reaching the wheels. OVERTAKE’s urethane rear differential bushing inserts fit directly over the existing OEM rubber while the included spacers clamp everything together, creating a unified, reinforced mount that dramatically reduces deflection under load. The 80a durometer urethane compound is formulated to withstand heat, oil, and environmental exposure for long-term durability. While a slight increase in NVH can be expected, most performance-oriented drivers welcome the added drivetrain feedback as a worthwhile tradeoff.
