Prothane 8-1139-BL Black 27mm Front Sway Bar Bushing Kit

The Prothane 8-1139-BL is a black polyurethane front stabilizer bar bushing kit designed for the 27mm front sway bar. Prothane's premium-grade polyurethane construction delivers a significant upgrade over soft, worn OEM rubber bushings, restoring and enhancing chassis control and steering response.

Key Features:

• 27mm bore diameter — precision-engineered to fit the front stabilizer bar exactly
• Premium-grade polyurethane construction — far more durable than factory rubber, resisting breakdown from road grime, oils, UV exposure, and weathering
• Grooved bore design — engineered to retain Prothane Super Grease for smooth, quiet operation without squeaking
• Firmer bushing compound — reduces body roll and improves cornering stability compared to stock rubber
• Black finish — maintains a clean, OEM-style appearance under the vehicle
• Precision fabrication — ensures correct fit and a secure grip on the sway bar without warping over time

Replacing worn stabilizer bar bushings with Prothane polyurethane units is one of the most cost-effective suspension upgrades available. The firmer material minimizes unwanted bar movement, giving the sway bar a more positive connection to the chassis and delivering handling improvements comparable to installing a larger sway bar.
