Super Pro Differential Mount

Super Pro Differential Mount Bushings: Precision-Engineered Polyurethane

When the rear differential shifts under load, drivers feel it — slower throttle response, vague steering, unwanted vibration, and noise that worsens over time. Differential mount bushings are the critical link between the differential housing and the subframe, and the factory rubber units that fill that role are notoriously short-lived, especially under hard use. Super Pro has spent decades developing a purpose-built polyurethane answer to this problem.

Why Factory Rubber Mounts Fail

OEM rubber differential mount bushings break down fairly quickly, with wear accelerating the harder they are used — and as they degrade, worn bushings allow more movement of the rear differential under changing loads. This can initially be felt as slower and sloppier responsiveness behind the wheel, and as the bushings near the end of their life, it can be accompanied by noise, vibration, and secondary movements under load — especially when getting on or coming off the throttle.

What Makes Super Pro's Differential Mounts Different

An Australian-based company, Super Pro began manufacturing replacement bushings from polyurethane after it was realized that OE rubber could not withstand the tough and extreme conditions found in Australia's notorious outback. That same durability philosophy defines every differential mount bushing in their lineup.

Super Pro differential mount bushings minimize power-robbing differential movement by replacing soft OE rubber bushings with high-durometer, two-piece polyurethane bushings — and critically, these polyurethane bushings effectively minimize wheel hop without contributing to road noise or driveline vibrations. This is a distinction that matters: polyurethane bushings have a reputation for increasing NVH, but Super Pro has spent years researching this flaw and now offers bushings that deliver polyurethane levels of performance without the NVH increase.

Super Pro's rear differential mount replaces the soft and fast-wearing OEM rubber mount; the 80A-durometer version is significantly more robust than the factory rubber units it replaces and improves performance while retaining OEM levels of NVH isolation. Their range also covers pinion mount positions: Super Pro rear differential pinion mount bushings are specifically designed to strengthen the rear differential mounting points and help transfer power more directly to the wheels.

Proprietary Materials & Lifetime Warranty

Super Pro bushings offer greater quality and reliability through their unique materials, made from a proprietary polyurethane mix that has been thoroughly tested and refined over 40+ years to suit Australia's harsh conditions. Super Pro is unique as the only polyurethane product range fully backed by a professional research and development program based on many years of hands-on experience in the suspension industry.

Every bushing kit in Super Pro's differential mount lineup is covered by their no-exclusions warranty. All Super Pro suspension bushings are covered by a Lifetime Warranty, meaning that if a Super Pro product fails, it will be replaced free of charge without exception.

Who These Mounts Are For

With polyurethane differential mount bushings, performance is significantly improved with the differential more accurately located under a wider range of conditions, and service life is dramatically improved — maintaining peak performance throughout the bushing's life rather than slowly softening and degrading like natural rubber. Whether you're building a track-day car, a weekend autocross machine, or simply want to restore crisp factory feel to a high-mileage daily driver, Super Pro's differential mount kits are engineered to fit and perform right the first time.
