BMW Rear Diff Rear Mount Bushing - Powerflex Street PFR5-326

Product Information

A differential mount is a component that secures the differential to the vehicle’s chassis or subframe. It absorbs and dampens the vibrations and torque generated by the differential, helping to maintain stability and alignment within the drivetrain. Differential mounts are typically made of rubber or polyurethane and play a crucial role in transferring power smoothly to the wheels.

• Clunking or Banging Noises: A common symptom of a failing differential mount is clunking or banging noises, especially when accelerating, decelerating, or shifting gears, as the differential shifts due to loose or damaged mounts
• Vibrations: Worn or damaged mounts can cause excessive vibrations in the drivetrain, leading to noticeable shaking or vibrating felt in the rear of the vehicle or even in the cabin.

About Powerflex

Installation instructions are included in all Powerflex kits

Powerflex has extensive knowledge and design experience in automotive suspension and chassis systems. These design skills have been combined with advanced polyurethane manufacturing techniques leading to the development of a wide range of high-performance automotive polyurethane components that are second to none in quality and performance.

Street Purple - Powerflex Street bushings are purple in color and are meant for street sport applications. Order this compound for daily driven cars and when ultimate performance is not a priority. In some positions, the street compound bushing may also be yellow.

Racing Black - Powerflex Racing bushings are significantly stiffer than their street counterparts, and are designed for vehicles that are driven on race tracks for minimum bushing deflection. Occasionally racing black bushings are denoted for use on street applications in positions where excess load puts significant demand on a bushing and NVH is not effected by the stiffer material.

All component manufacturing is carried out by our in-house engineers utilizing the latest automatic processing equipment to ensure premium quality. Testing of new components is carried out both on test rigs and on the actual vehicle the parts are designed for. Stainless steel and aluminum components are also machined in-house on the latest computer-controlled equipment to ensure perfect repeatability and exceptional quality.

The special type of polyurethane used by Powerflex is an advanced proprietary material which has unique properties. This ensures that each product not only offers the high-performance capabilities our customers expect, but also the exceptionally long life and quality they demand - without increased vibration or noise.
