Powerflex PowerFlex 7 Series Rear Sway Bar Bushing 10mm - E38 PFR5-504-10H

PowerFlex 7 Series Rear Sway Bar Bushing 10mm - E38

The E38 is a legendary chassis, but its weight demands a lot from the suspension. Upgrading to the 10mm Powerflex rear sway bar bushing is one of the most cost-effective ways to restore that taught, 'planted' European driving dynamic without sacrificing the ride quality the 7 Series is famous for.

PowerFlex 7 Series Rear Sway Bar Bushing 10mm - E38
$57.99

In professional motorsport, chassis stability and predictable handling are everything. The BMW E38 7 Series is a legendary touring platform, but its factory rubber bushings are prone to degradation, causing unwanted deflection, vague steering feedback, and compromised rear-end geometry under load.

The Powerflex Rear Sway Bar Bushing is engineered to eliminate that compliance. By upgrading the factory 10mm rear anti-roll bar mounts to Powerflex’s advanced polyurethane compound, you restore the precise, razor-sharp handling characteristics your chassis demands—without sacrificing the refined ride quality of a premium luxury sedan.

Technical Specifications & Features

  • Engineered Material: Proprietary polyurethane compound designed for high tear strength, memory retention, and resistance to oil, fuel, and road grime.

  • Precision Fitment: Molded specifically for the 10mm rear sway bar found on select E38 7 Series models.

  • Performance Longevity: Outlasts standard rubber bushings by up to 4x, maintaining consistent suspension geometry over the lifespan of the vehicle.

  • Advanced Internal Knurling: Features internal grooving designed to retain the included high-performance grease, ensuring silent, squeak-free operation and reduced friction.

  • Lifetime Warranty: Backed by Powerflex's comprehensive manufacturer lifetime warranty.

  • Optimized for the Street: The Road Series (80 Shore A) compound increases stiffness by roughly 25–30% over brand-new rubber, offering a massive upgrade in handling precision without introducing harsh Noise, Vibration, or Harshness (NVH) into the executive cabin of your 7 Series.

  • Lifetime Durability: Unlike rubber, which degrades from exposure to ozone, oil, road salt, and time, Powerflex polyurethane is impervious to the elements. This is the last rear sway bar bushing your E38 will ever need.

Fitment Note: We recommend measuring your rear factory or aftermarket sway bar to determine which size of bushings are required for your vehicle. Sway bar sizes can differ depending on factory suspension packages and aftermarket sway bar brands.
