Prothane 4-1142-BL Front Sway Bar Bushing Kit 32mm Black Polyurethane

The Prothane 4-1142-BL is a front stabilizer bar (sway bar) bushing kit designed to replace worn or soft factory rubber bushings with firm, long-lasting black polyurethane bushings sized for a 32mm bar diameter. Upgrading to polyurethane delivers noticeably improved body roll control, sharper cornering response, and more consistent sway bar performance compared to stock rubber components.

Prothane's polyurethane material maintains a secure, consistent grip on the sway bar and resists warping, compression set, and deterioration from road grime, oils, and weather exposure — common failure modes for OEM rubber bushings. The bushings feature grooved bores engineered to retain Prothane's proprietary super grease, ensuring quiet, squeak-free operation after installation.

Key Features:

• 32mm bore diameter — fits OEM and compatible aftermarket front stabilizer bars
• Black polyurethane construction — firmer and more durable than factory rubber
• Grooved inner bore designed to hold Prothane super grease for noise-free operation
• Resists degradation from oil, grease, road chemicals, and UV exposure
• Maintains consistent sway bar position to reduce body roll and improve cornering traction
• Performance upgrade comparable to installing a larger diameter sway bar
• Made in the USA
• Backed by Prothane's Lifetime Warranty

This kit is an ideal solution for restoring or enhancing front suspension performance on vehicles equipped with a 32mm front stabilizer bar. Prothane polyurethane bushings are a direct, bolt-on upgrade that outperforms OEM rubber right out of the box.
