BMW Rear Sway Bar Bushing (18 mm) - Powerflex Race PFR5-504-18BLK

Upgrade your BMW's rear suspension for track and fast road use with the Powerflex Race Black Series Rear Sway Bar Bushings. These high-performance 18mm polyurethane bushings (PFR5-504-18BLK) are engineered to significantly reduce sway bar deflection, delivering razor-sharp handling, minimized body roll, and a more direct, responsive feel compared to softer OEM rubber.

The durable Black Series compound provides maximum stiffness and longevity, making them ideal for demanding driving conditions. This bushing is specifically designed for various BMW E36 (1992-1999) 3-Series models with an 18mm sport suspension rear sway bar, and select E46 (2000-2006) 3-Series and E85/E86 Z4 (2003-2008) models typically equipped with an 18mm standard rear sway bar. Always measure your existing rear sway bar to confirm the 18mm diameter for proper fitment.
