PowerFlex Rear Sway Bar Bushing - 19 Mm - E28, E24

Product Details

In historic motorsport, vintage rallying, and high-performance classic tuning, success is defined by mechanical predictability and continuous contact patch optimization. The factory rubber rear sway bar bushings on classic BMW chassis are known points of compliance. Under high lateral G loads, standard rubber deflects, causing a dynamic delay in sway bar rate conversion, unexpected rear-end geometry shifts, and a less communicative rear axle.

The Powerflex Heritage Collection is engineered specifically for competitive applications requiring modern polyurethane performance advantages without violating strict historic aesthetic guidelines or introducing overly harsh NVH (Noise, Vibration, and Harshness) that can stress vintage chassis points. Formulated in a classic dark grey finish, it seamlessly integrates into period-correct builds while providing modern, elite-level track handling.

Technical Performance Metrics

• Eliminated Elastomer Deflection: Designed to maintain absolute dimensional stability under severe racing loads, ensuring instantaneous rear anti-roll bar activation and a flatter, more stable cornering attitude.

• Aesthetic Compliance: Specially blended in a dark grey finish to mimic the appearance of a standard rubber bushing. Ideal for vintage racing series, concours preparation, or high-end classic restorations where a bright polyurethane color is undesirable.

• Proprietary Advanced Material: Features a highly resilient polyurethane compound with unique memory properties. It offers superior resistance to environmental degradation, track oil, heat cycling, and high-load friction compared to OEM rubber.

• Optimized Internal Lubrication Grooves: Molded with internal friction-reducing recesses designed to retain high-pressure copper grease, guaranteeing non-binding articulation and eliminating the risk of stick-slip squeaks during high-frequency suspension movement.

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.
