Civic Rear Sway Bar Bushings 12mm

The Prothane Civic Rear Sway Bar Bushings 12mm (part number 8-1134) are high-performance polyurethane replacement bushings engineered to restore and enhance suspension response on Honda Civic models from 2001 to 2005. As OEM rubber bushings deteriorate over time, they allow excessive sway bar movement, compromising handling precision and increasing body roll during cornering. These Prothane sway bar bushings replace that worn compliance with a firmer, more controlled suspension geometry.

Constructed from proprietary polyurethane material, Prothane's rear sway bar bushings are engineered to be non-greasable, eliminating the maintenance interval associated with traditional rubber components. The 12mm bar diameter specification matches the factory rear sway bar on applicable Civic generations. The supplied pair covers both sides of the suspension, and the distinctive red color identifies them as performance-grade components. Polyurethane bushings maintain their stiffness across temperature ranges better than stock rubber, translating to more consistent handling feel whether driving in cold starts or sustained hard cornering.

These bushings are ideal for Civic owners seeking measurable suspension improvements without a complete system overhaul. Typical applications include street performance driving, autocross preparation, and general suspension restoration on vehicles showing worn-out OEM bushings. The upgrade addresses a common point of degradation in aging Civics, where sway bar compliance becomes noticeable through softer responses to steering inputs and increased lean angles in turns. Installation requires basic suspension work and is compatible with both stock and modified setups targeting improved handling balance.
