Differentials serve the key purpose of transmitting power from the driveshaft to the axles. Factory rubber bushings absorb some of this power to allow for cushy, comfortable acceleration, at the expense of performance. Many OEM differential bushings are fast-wearing and failure-prone, resulting in driveline slop and thunks when shifting or going over bumps. Your BMW G80/G82/G87 will improve in: Improved Handling and Stability - Upgrading to an aftermarket rear differential front mount bushing can do wonders for your car's handling and stability. These bushings are designed with performance in mind, reducing unwanted movement of the differential. Reduced Wheel Hop - Wheel hop can be a drag, both figuratively and literally. An upgraded front mount bushing helps minimize wheel hop, especially during hard acceleration or aggressive driving. Say goodbye to that unsettling bounce and hello to smoother power delivery. Powerflex polyurethane differential bushings are firmer than OEM rubber bushings, eliminating associated driveline slop and allowing for the crisp application of power to the ground, resulting in better throttle response and control. Powerflex is the number one selling suspension bushing manufacturer in Europe. Their experience with polyurethane bushing material and state-of-the-art manufacturing techniques allows them to produce premium performance bushings, made to exact-fit standards. Powerflex performance polyurethane bushings are built to last longer than OEM rubber bushings while improving performance and allowing for a more engaging driving experience. The use of Powerflex Copper Grease PCG1 is recommended for ease of installation. Periodic reapplication is recommended to extend the squeak-free service life of bushings. Powerflex Black Series bushings are the ultimate in track and race bushings. Need bushings for a car that's street-driven? Powerflex street bushings are an ideal alternative for street-driven vehicles and those that see occasional autocross or track time.

The Powerflex Rear Diff Mount Bushing for the BMW E21 offers a robust solution to support and stabilize the differential, replacing the standard rubber bushings with durable polyurethane. This upgrade minimizes unwanted differential movement, enhancing driving dynamics and responsiveness.

Key Benefits:

Enhanced Stability: By minimizing differential movement, Powerflex bushings ensure consistent alignment, giving better rear-end stability.
Improved Longevity: Unlike rubber, polyurethane is resistant to aging and degradation from elements like oil and road debris.
Responsive Handling: With reduced play in the differential mount, power transfer becomes more direct, allowing for sharper throttle response.
Vibration Dampening Options: Powerflex offers options like the Black Series for motorsport applications and the standard Purple for everyday performance with minimal increase in vibration.

These bushings are popular among E21 owners who want a durable, performance-oriented solution that balances comfort and handling precision. Ideal for both spirited driving and daily use.
