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.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Engineered to perform, Powerflex performance polyurethane differential bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

This package of OEM E82 E90 E92 diff mounts replaces the stock rubber diff bushings. On a tuned 335i you may have noticed more driveline shudder or problems hooking up during hard launches. What happens is the stock rubber bushings are under constant flex as engine torque is transmitted through the differential. Under normal driving with a stock car the bushings are rarely stressed. But factor in significant additional torque from a tuned N54/N55 and the stock rubber will quickly show its weaknesses. You may have even broken a diff bolt or two as the heavy differential shifts around. Even non-turbo E82 and E9X models may benefit from fresh bushings.

This is a set of stock rubber bushings, made by OEM supplier Lemforder. They are the same as the Genuine BMW E9X diff mount bushings, but without the more expensive branding. If you're turned off by potential side effects of urethane or Delrin then the OEM diff mounts are your best option. The OEM mounts fit and perform just like the originals so there is no second guessing their quality. If you're looking for an upgrade we offer E9X solid Delrin and aluminum diff mounts that work well, even in street applications.

E9X Diff Mount Set includes:

  • 33176760287 x 2, front differential mount
  • 33176770866 x 1, rear differential mount
  • (new hardware is optional and can be ordered separately below)

BMW does not sell the differential mounts separate from the cover. And as with all rubber mounts, they will have to be replaced at some point, forcing you to also buy a new diff cover. This is an Original BMW part.
**Note** - a paper gasket is not sold with this cover. BMW no longer uses paper gaskets - they advise the use of a silicone sealant such as RTV black.

Applications:
2001-2006 E46 M3, M3 CSL, coupe and convertible
