Porsche Strut Mount Bushing Set - Powerflex PFF57-406H

Product Information

Strut mounts are a frequent wear component on vehicles with MacPherson suspension systems. These mounts secure the top of the strut to the chassis and serve as a pivot point for steering. Over time, especially with higher mileage, the strut bearing can degrade, leading to a rougher feel and reduced steering performance. Additionally, the rubber in the mount may crack, causing looseness and other issues. To ensure optimal performance and longevity, we recommend replacing the strut mounts whenever installing new strut assemblies.

• Clunking or knocking noises: A worn strut mount may cause clunking or knocking sounds, especially when driving over bumps or rough roads
• Excessive vibration: If the rubber in the mount is cracked or deteriorating, it may lead to increased vibrations felt through the steering wheel or chassis
• Poor steering response: A faulty strut mount can affect the vehicle's steering alignment, leading to difficulty in turning or reduced steering responsiveness
• Uneven tire wear: When the strut mount fails, it can alter the suspension geometry, causing uneven or premature tire wear
• Increased body roll or sway: A worn mount can compromise suspension stability, leading to more pronounced body roll during cornering

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.
