Prothane 7-1185BL Rear Sway Bar Bushing Kit 24mm Black Polyurethane

The Prothane 7-1185-BL is a black polyurethane rear sway bar bushing kit designed for the 24mm rear stabilizer bar. This kit is a direct performance upgrade over worn or soft factory rubber bushings, delivering improved handling response and reduced body roll.

Prothane's polyurethane compound resists breakdown from road grime, oils, weather, and road salts that cause OEM rubber bushings to crack, warp, and lose their grip over time. By maintaining a consistent, secure grip on the sway bar, these bushings restore and enhance the effectiveness of your rear stabilizer system — delivering handling gains comparable to installing a larger diameter sway bar.

Key Features:

• Premium-grade black polyurethane construction — more durable than factory rubber, resists deterioration from oils, grime, and weather exposure
• 24mm inner diameter — precision-fit for the rear sway bar
• Reduces body roll — maintains a secure grip on the sway bar to maximize its effectiveness during cornering
• Includes Prothane Super Grease — apply at installation to ensure quiet, squeak-free operation
• Precision fabrication — engineered for a correct, rattle-free fit
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of ownership

Installation requires proper lubrication of the bushing interior with the included Super Grease. The black formulation contains a small amount of graphite which can further aid in noise reduction. Prothane part number 7-1185-BL; the red color variant is sold as part number 7-1185 with no difference in performance or durometer.
