These bushings install into the voids in the factory rear diff mount bushings to add firmness to the rear differential. Better control of the rear diff keeps it from slamming against the chassis during hard shifts, and helps to put power down to the road where it belongs.

Red polyurethane construction.

Set of four bushings, plus a pack of lubricant and a Racecomp Engineering decal.

Fits all 2008+ Subaru WRX, including 2022+, and 2008-2021 WRX STI.
