Choose from 95A durometer polyurethane (performance-spec), 75D durometer polyurethane (race-spec), or 6061 T6 Aluminum (insanity-spec) depending on your application. Powerflex Bushings are designed to address common factory failure parts, Powerflex bushings allow the articulation required to far outlast the stock part it is. Your factory bushings are almost certainly worn out anyways so it is in your best interest to upgrade them instead of just replacing them with new rubber bushings (the alternative of not replacing them at all is just too horrible to even consider, please don't do that to yourself). Polyurethane bushings help to keep the differential from flexing which provides improved power transfer and more immediate response to throttle inputs.

-CNCd 6061- T6 aluminum: Very High NVHįactory rubber differential mount bushings are soft, wear out quickly and adversely affect power transfer through the drivetrain.Military Spec 75D durometer compound (Red): High NVH Military Spec 95A durometer compound (Black): Moderate NVH Good feedback from the road is essential for precise car control and can give you the edge in your lap time.Polyurethan bushings improve road feel and alignment consistency so you aren't dealing with sudden jolts or jitters under braking and cornering.The bushing in the rear subframe is often cause for failure causing the rear end to clunk from moving around.
