Whiteline Rear Diff Positive Power Kit Inserts - STI 2004 / WRX 2002-2004 / Impreza 1993-2003 / More
The Whiteline Rear Diff Positive kit bushings are designed to reduce the initial torque loss and movement through the rear differential mounts during acceleration and deceleration. These inserts fill in the voids that are in the OEM bushings and help to stiffen the rear differential. They are a great upgrade for anyone looking to improve the performance of their car.
