Specifications
Part Details:
The factory rear differential mount bushings on these Subaru platforms are soft rubber, which flexes under hard acceleration and shifting, causing a noticeable clunk during aggressive shifts and letting power flex the mount instead of putting it to the tires. This Torque Solution insert kit replaces that soft rubber with 75A durometer polyurethane, eliminating the clunk and tightening up throttle response and shift feel.
Torque tested to over 1000 horsepower and 8-second quarter mile passes. A cheap, effective upgrade for anyone chasing sharper feedback or dealing with an annoying hard-shift clunk.

Some added driveline feedback is expected with a stiffer bushing, most owners describe it as more direct and predictable rather than harsh.
