Powerflex Single Black Series Rear Diff rear Right Mount Insert - Appears in Position 31 on Diagram

The Powerflex Single Black Series Rear Diff Right Mount Insert is an upgraded polyurethane engine & gearbox mount designed to provide superior performance and handling during spirited road or track driving. Unlike stock mounts that prioritize noise, vibration, and harshness reduction, the Powerflex upgrade is engineered to minimize flex in the engine mounting, resulting in less engine movement and improved sound damping.

The Powerflex Red compound (product code ends with R) is the softest option available, ideal for diesel engines due to its ability to soak up the most noise and vibration. While it can be used on petrol engines, its primary purpose is to reduce NVH in diesel engines, which produce more vibrations.

Alternatively, the Yellow compound is a middle ground that's not normally recommended for diesel engines as it would transmit too much NVH. The Purple compound (product code ends with P) is the stiffest option short of the Black Series and is typically recommended for track use, where some additional NVH will be experienced. However, it's not suitable for diesel engines.

For those seeking the highest level of rigidity, the Powerflex Black Series bushes are available for select cars, utilizing the hardest compound to provide exceptional performance and minimal flex. However, this option will transmit more NVH than other options.

In conclusion, the Powerflex Single Black Series Rear Diff Right Mount Insert is a high-performance upgrade that provides enhanced handling and reduced engine movement, making it an excellent choice for those who demand the best from their vehicle.
