Rubber factory sway bar bushings deflect under load, introducing slop into the front suspension before cornering forces even peak. Prothane's polyurethane replacements eliminate that compliance, giving your 1979-2004 Mustang a direct, predictable front end that responds the moment you ask it to turn.
Polyurethane construction that holds its shape. Unlike rubber, polyurethane resists compression set, oil contamination, and UV degradation over time. These bushings maintain consistent stiffness across the full range of driving conditions, from daily commutes to track days, without the gradual softening that plagues OEM rubber pieces.
Sized specifically for 1-3/8 inch front sway bars. The 1-3/8 inch inner diameter fits many sway bar offerings for the Fox Body, SN95, and New Edge generations. No shimming, no adaptation, and no binding at the clamp bracket.
Prothane Super Grease included. Every set ships with Prothane's Super Grease, formulated to work with polyurethane so the bushings stay lubricated and squeak-free.
Your choice of finish. Available in red or black to suit the suspension aesthetic you already have in place.
