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.

Features

  • 80A durometer performance urethane bushings
  • Designed to slip over OEM bushings—no removal required
  • Quick 20-minute installation with basic hand tools
  • No cutting, drilling, or permanent modifications

What You’ll Feel

  • Crisper throttle response with more direct power delivery
  • Improved rear-end stability through corners
  • Sharper, more precise gear changes

Includes:

  • (2) Front Rear Differential Inserts
  • (2) Rear Rear Differential Inserts
  • (2) Bushing Washers
