SuperPro's rear differential mount replaces the soft and fast-wearing OEM rubber mount. The 90A version found here offers significantly reduced deflection under load and more positively locates the rear differential under power application and hard shifts better and more efficiently transmitting power and making for quicker shifts and less interruption in power delivery. The higher durometer material can result in a small amount of additional NVH. We recommend this version over the standard versions for high-horsepower applications and those that see track use (circuit or drag racing).

Manufacturer's Warranty — SuperPro
SuperPro Suspension Bushings, Sway Bars and Suspension Arms are covered by a Lifetime Warranty against manufacturing defects, and SuperPro places no limitation on the scope of use — on-road, off-road, racetrack and competitive motorsport all remain warranty-eligible. Ball Joints, Tie Rod Ends, Duroballs and Links are covered by a 3-year / 36,000-mile / 60,000-km warranty. Cover is limited to replacement of the originally supplied SuperPro component, and SuperPro may supply a superseded version; it does not reimburse or refund warranty-eligible products, installation, alignment or related expenses. Product finish and normal wear are excluded, including surface degradation and corrosion from road salt, debris or the elements, as is damage or premature wear caused by incorrect installation or by failing to align the wheels as recommended. Removal and replacement labour and consequential damage are not covered where local law permits that limit. A claim requires proof of original purchase from an authorised reseller showing the claimant as the purchaser, and the part must have been originally supplied for the specific application listed in the SuperPro catalogue.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by SuperPro. Contact us if you need help with a warranty claim.
