05-06 Mustang V6 Sway Bar Bushing Kit

The PROTHANE 05-06 Mustang V6 Sway Bar Bushing Kit is a rear suspension upgrade engineered to replace worn OEM rubber bushings on 2005–2006 Ford Mustang V6 models. This polyurethane bushing kit fits the 18mm rear sway bar and delivers measurable improvements in cornering response and suspension geometry stability that stock rubber components cannot maintain under sustained driving loads.

Polyurethane bushings offer superior durability compared to OEM rubber, which hardens and deteriorates over time—particularly in high-heat engine bays and under repeated lateral stress during aggressive cornering. The black polyurethane formulation resists UV degradation, ozone exposure, and brake fluid contact better than factory rubber. At 18mm, this sway bar diameter is the OEM specification for Mustang V6 models, making this kit a direct replacement without modification. The complete bushing set ensures even load distribution across both sides of the rear sway bar, maintaining proper suspension alignment and eliminating the wandering or mushy feedback that develops as bushings wear.

This kit addresses a common suspension maintenance point for Mustang owners seeking improved handling characteristics on street and track applications. Factory bushings typically begin showing visible wear between 40,000 and 80,000 miles, resulting in noticeable body roll increase and reduced feedback through the steering. Installation requires standard hand tools and suspension jack work, making it accessible for home mechanics or a professional shop. PROTHANE's polyurethane formulation does produce a slight creaking sound during initial break-in as the material settles—this is normal and typically subsides after 500–1,000 miles of driving.
