Product Details
In the world of professional motorsport, chassis precision and predictable handling are everything. The luxury-focused, rubber-isolated factory rear sway bar bushings on the BMW E38 7 Series are a notorious weak point, prone to rotting, flexing, and stretching over time. This leads to a vague rear-end feel and delayed body roll response.
The Powerflex Road Series Rear Sway Bar Bushing is engineered to bridge the gap between track-ready precision and street-driven refinement. Designed specifically for E38 models equipped with a 10mm factory rear sway bar, this polyurethane upgrade stabilizes the rear anti-roll bar, allowing it to do its job instantly without deflecting under cornering loads.
The Powerflex Advantage: Road Series (Purple)
Eliminate Dynamic Deflection: Standard rubber deflections cause unpredictable geometry changes mid-corner. Powerflex’s proprietary polyurethane formulation maintains structural integrity under load, sharpening turn-in and settling the rear chassis.
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.
