Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

The Powerflex Rear Diff Front Mount Bushing (Race) for BMW E34 5 Series and E32 7 Series is a premium upgrade designed for enhanced drivetrain stability and performance. Here’s another description:

  • Race-Grade Polyurethane: Part of Powerflex’s Race Series, this bushing is crafted from a super-stiff polyurethane compound, designed to eliminate the excessive movement found in factory rubber bushings. The Race Series is optimized for track and high-performance driving, where minimizing flex is crucial for precision handling.

  • Purpose: This bushing replaces the front mount of the rear differential, a critical point where unwanted flex can reduce performance. By stiffening this mount, the bushing ensures improved power transfer to the wheels and reduces drivetrain slop, making the car feel more connected and responsive.

  • Key Features:

    • High Durability: Polyurethane in the Race Series is resistant to wear, oil, and contaminants, offering longevity far superior to rubber bushings, especially in harsh driving conditions.
    • Maximized Control: The stiffer material prevents the differential from moving excessively under load, providing more consistent traction and improved rear-end stability.
    • Straightforward Installation: This bushing is a direct replacement for the stock component, making it easy to fit and offering immediate performance benefits without extensive modifications.
  • Benefits:

    1. Enhanced Power Delivery: By limiting differential movement, the car experiences less drivetrain lash and more precise power delivery, which is especially noticeable during hard acceleration and cornering.
    2. Reduced Differential Flex: The reduction in flex at the diff mount allows for improved handling and cornering response, making the car more predictable and stable at higher speeds.
    3. Track and Performance Ready: The Race Series bushing is designed for drivers who demand the best from their vehicles, especially in motorsport settings where precision and durability are key.
  • Fitment: Tailored specifically for the BMW E34 (5 Series) and E32 (7 Series) models, this bushing replaces the front differential mount and offers a perfect fit, ensuring no compromises on installation or function.

In summary, the Powerflex Rear Diff Front Mount Bushing (Race Series) is an essential upgrade for BMW E34 and E32 owners looking for improved drivetrain rigidity, better handling, and longer-lasting components. Perfect for performance enthusiasts and track-goers, it enhances rear suspension control and reduces drivetrain movement for sharper, more precise driving experiences.
