Prothane 4-1141-BL Front Sway Bar Bushing Kit 30mm Black Polyurethane

The Prothane 4-1141-BL is a front stabilizer bar bushing kit designed to replace worn or soft OEM rubber bushings on 30mm sway bars. Upgrading to Prothane's polyurethane bushings delivers a noticeable improvement in handling precision and body roll control compared to stock rubber components.

Key Features:

• 30mm bore diameter — engineered for a precise fit on 30mm front stabilizer bars
• Grooved bore design — channels are machined into the bore to retain Prothane Super Grease, ensuring quiet, squeak-free operation
• High-durometer polyurethane construction — firmer than OEM rubber for improved steering response and reduced body roll
• Black finish — color-coded black (BL) for easy identification
• Direct OEM replacement — bolt-in fitment with no modifications required
• Includes Prothane Super Grease — specially formulated lubricant compatible with polyurethane for long service life

Prothane polyurethane bushings are manufactured to tighter tolerances than stock rubber, reducing unwanted suspension deflection and improving overall chassis response. The grooved inner bore works with the included super grease to eliminate the noise concerns often associated with polyurethane upgrades, making this kit equally suitable for daily drivers and performance applications.
