The aluminum bushing kit offers a dramatic reduction in wheel-hop under hard acceleration by eliminating the deflection that rubber bushings normally present. The zero-deflection aluminum bushing offers dramatically improved grip on corner exit or under hard launches at the drag strip. Also the aluminum acts as a heat-soak to absorb heat generated by the rear differential. The kit also has a series of shims which are built-in to the design, but can be removed one at a time allowing you to adjust the pinion angle to compensate for lowering the vehicle or to fine tune the drivetrain and eliminate unwanted vibrations.

The Cobra IRS has a problem with excessive rear steer induced by body roll during cornering that can impair handling.
