Prothane 18-1101-BL Front Sway Bar Bushing Kit 18mm Black Polyurethane

The Prothane 18-1101-BL is a front sway bar bushing kit designed as a direct performance upgrade over factory rubber bushings. Manufactured from Prothane's proprietary polyurethane compound, these bushings deliver firmer, more consistent support to the front stabilizer bar, reducing body roll and improving cornering response.

The bushing bores feature precision-machined grooves engineered to retain Prothane's high-performance super grease, ensuring smooth, quiet operation over the life of the bushing. This kit fits 18mm (0.708 in.) diameter front sway bars and is finished in durable black.

Prothane polyurethane suspension components are precision-engineered to outperform soft factory rubber, delivering tighter handling and more predictable suspension response. Confirm your sway bar diameter prior to ordering, as diameter can vary by vehicle trim and option package.
