Whiteline Rear Differential Mount Inserts Positive Power Kit Subaru 2008-2021 WRX / STI

Whiteline's 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.

Features:
- Low compliance synthetic elastomer inserts that fill the voids of the OE bushing which reduces initial torque loss movement through rear differential mounts during acceleration-deceleration.
