Prothane 14-1113 Rear Sway Bar Bushing Kit 23mm Polyurethane

The Prothane 14-1113 is a rear stabilizer bar bushing kit designed as a direct upgrade over worn or soft OEM rubber bushings. Engineered from premium-grade polyurethane, these bushings deliver a firmer, more consistent grip on the 23mm rear sway bar, helping restore and enhance chassis stability and handling performance.

Why Upgrade to Polyurethane?

Stock rubber sway bar bushings can warp, crack, or lose their grip over time, causing the stabilizer bar to lose effectiveness — resulting in increased body roll and reduced cornering traction. Unlike rubber, polyurethane does not break down from road grime, moisture, or oil exposure, providing long-lasting performance over the life of the vehicle.

Key Features:

• Premium polyurethane construction — more durable than OEM rubber
• Designed for a 23mm (0.90 inch) rear sway bar diameter
• Grooved bore design retains Prothane Super Grease for quiet, squeak-free operation
• Maintains a secure grip on the sway bar — will not warp or deform over time
• Available in red or black (same durometer hardness — cosmetic difference only)
• Backed by Prothane's lifetime warranty
• Made in the USA

Upgrading to Prothane polyurethane sway bar bushings delivers a performance improvement comparable to installing a larger diameter sway bar. Be sure to apply the included Prothane Super Grease during installation to ensure quiet, long-term operation.
