BMW Rear Upper Arm Inner Bushing - Powerflex PFR5-712

Product Information

Control arms are links that help connect and stabilize the vehicle's suspension to the subframe of the vehicle. Many vehicle’s, while varying in suspension layout, will have control arms with serviceable bushings and/or joints on either end where they meet the undercarriage or spindle of the vehicle.

As the rubber on these bushings degrades or cracks they will no longer provide a rigid connection and cause problems in handle and ride quality. Often times to save time and cost it is possible to press out the original worn bushing and press in a replacement instead of replacing the complete control arm. Common failure symptoms of faulty control arms bushings include:

• Uneven tire wear and inability to align vehicle
• Poor handling characteristics
• Loud clunking, metal on metal sounds, suspension buckling
• Vibration or wobble in the steering wheel
• Banging sound over bumps

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.
