OVERTAKE Rear Differential Lower Bushing Inserts – Subaru 2008-2026 WRX, 2008-2021 STI

Description:

What if every shift, every corner, and every launch felt tighter and more connected?

Your rear diff is mounted with soft factory rubber that flexes and twists under load, robbing you of power transfer and dulling the feedback you crave. The OVERTAKE Rear Differential Upper Bushing Insert Kit fix that with performance-rated 80A durometer urethane bushings that reinforce your factory mounts and eliminate unwanted movement. Small part, big improvement in feel.

The Details

The rear differential is the heart of your Subaru's AWD system, and the factory rubber mounts were designed for comfort, not performance. Every time you hammer the throttle or dive into a corner, those soft bushings allow the differential to shift and move, wasting energy that should be going to the wheels. Our OVERTAKE urethane rear differential bushing inserts slip directly over your existing OEM Subaru rear diff rubber while the spacers sandwich everything together, creating a unified mount that virtually eliminates deflection under load. The urethane is formulated for long-term durability and resists heat, oil, and environmental degradation. Expect a slight increase in NVH, but most enthusiasts find this trade-off worthwhile and actually prefer the added drivetrain feedback.
