Prothane 18-1129-BL Rear Sway Bar Bushing Kit 23mm Black

The Prothane 18-1129-BL is a polyurethane rear sway bar bushing kit designed as a direct, performance-upgrade replacement for worn or soft OEM rubber bushings. Engineered for a precise 23mm bar diameter, this kit delivers firmer, more consistent bushing performance to help reduce body roll and sharpen handling response.

Over time, stock rubber sway bar bushings can warp or crack, causing the stabilizer bar to lose its grip and effectiveness. Prothane's polyurethane material resists deterioration from road grime, weather, and oils — maintaining a secure fit on the bar throughout the life of the vehicle. The result is improved suspension response comparable to upgrading to a larger sway bar, without the added expense.

Key Features:

• Material: High-performance polyurethane — significantly more durable than OEM rubber
• Bar Diameter: Fits 23mm (0.90 inch) rear stabilizer bars
• Color: Black — formulated with a small amount of graphite to help minimize squeaking
• Grooved Bore Design: Channels hold Prothane Super Grease for quiet, smooth operation
• Includes: Prothane Super Grease pre-lube for proper installation lubrication
• Warranty: Lifetime warranty — covers defects in materials and workmanship for the life of original vehicle ownership
• Available in black (18-1129-BL) or red (18-1129)

For best results and squeak-free performance, apply the included Prothane Super Grease to each bushing thoroughly during installation. Prothane polyurethane bushings are a proven, cost-effective suspension upgrade for drivers looking to restore or enhance the performance of their vehicle's anti-roll system.
