Construction & Design

The SuperPro sway bar bushings are crafted from a proprietary polyurethane elastomer that combines flexibility with exceptional durability. This material resists compression set, cracking, and deterioration over time, ensuring a long service life. The bushings feature a one-piece design with precise molding to match OEM dimensions, facilitating straightforward installation without modifications. The internal bore is engineered for a snug fit around the sway bar, minimizing movement and maximizing stability. The outer surface is smooth and resistant to environmental factors, maintaining performance even after prolonged exposure to the elements.

Installation & Fitment

The SuperPro sway bar mount bushings are designed as direct replacements for OEM parts, making installation straightforward for those familiar with suspension work. No special tools or modifications are required, and the process typically involves removing the wheels, unbolting the sway bar brackets, and replacing the old bushings with the new polyurethane units. Proper lubrication of the bushing inner bore is recommended to ensure smooth operation and longevity. The bushings are compatible with the factory sway bar mounting points on all 2010–2022 BMW 1-Series E8X models with a 21.5mm sway bar.
