Powerflex Rear Sway Bar Bushing - 18.5 Mm - E83 - M54, N52

Product Details

When every millisecond counts, body roll is the enemy of momentum. The PowerFlex Black Series Rear Sway Bar Bushing (18.5mm) is engineered specifically for the BMW X3 (E83, 2003–2010) chassis to eliminate compliance, sharpen transient response, and maintain maximum tire contact patch under extreme cornering loads.

Developed for track, race, and high-performance applications, the Black Series is PowerFlex’s ultimate motorsport compound, designed for drivers who demand zero-compromise chassis control.

Technical Features & Advantages

• 95 Shore A Polyurethane Compound: Manufactured using a proprietary, ultra-high durometer polyurethane. This compound is 25% stiffer than the standard PowerFlex Purple material and up to 80% more resistant to deflection than factory rubber.

• Knurled Bore for Lifetime Lubrication: Features a precision-engineered internal knurled bore. This retains specialized high-pressure grease, ensuring silent operation, reducing friction, and eliminating the binding common in inferior aftermarket bushings.

• Advanced Material Memory: Unlike standard rubber that perishes, cracks, and softens over time under heavy load, PowerFlex polyurethane maintains its structural integrity and design geometry indefinitely.

• Direct Bolt-On Fitment: Engineered to install directly into the factory BMW housing brackets without requiring structural modification.

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.
