BMW F10/F11 Rear Sway Bar Bushing - 18mm

Product Details

Eliminate chassis deflection and unlock the true handling potential of your BMW with the Powerflex Black Series Rear Anti-Roll Bar Mounting Bushing. Designed specifically for the rigorous demands of competitive motorsport, this 18mm upgrade replaces compliant OEM rubber bushings with a high-durometer, track-ready polyurethane compound, delivering uncompromised suspension geometry retention and lightning-fast chassis response.

The Motorsport Advantage

In high-speed cornering and rapid transitions, factory rubber bushings flex, causing delayed anti-roll bar activation and unpredictable handling. The Black Series compound is manufactured from a specialized 95 Shore A durometer polyurethane. This ultra-stiff material is engineered to withstand extreme cornering forces, ensuring that your anti-roll bar deflects exactly when and how it was designed to, providing immediate feedback and maximum tire contact patch utilization.

Key Performance Features

• 95 Shore A Black Series Compound: Powerflex’s stiffest material formulation, offering an approximate 25% increase in load resistance over standard performance polyurethane and up to 80% less deflection than OEM rubber.

• Optimized Chassis Dynamics: Drastically reduces body roll latency, enabling sharper turn-in, improved mid-corner stability, and sharper throttle-steering capability.

• Advanced Lubrication Channels: Features internally knurled bores designed to retain specialized high-pressure grease, ensuring silent, bind-free operation under maximum load.

• Corrosion & Chemical Resistant: Impervious to oil, fuel, road salt, and ozone—ensuring long-term durability in grueling endurance racing environments.

• Lifetime Warranty: Backed by Powerflex's legendary motorsport heritage and lifetime guarantee.

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.
