Prothane 7-1163-BL Front Sway Bar Bushing Kit 23mm Black Polyurethane

The Prothane 7-1163-BL is a front stabilizer bar bushing kit designed as a direct-fit upgrade over worn or soft OEM rubber bushings. Manufactured from Prothane's proprietary polyurethane compound, these bushings deliver a firmer, more precise grip on the 23mm front sway bar — reducing body roll, improving cornering traction, and restoring crisp handling response.

Unlike factory rubber bushings that degrade over time from road grime, oils, and weather exposure, Prothane polyurethane bushings hold their shape and do not warp, providing long-lasting performance. Each bushing features a grooved inner bore engineered to retain Prothane's included super grease, ensuring smooth, quiet operation throughout the bushing's service life.

Key Features:

• Firm polyurethane construction — significantly more durable than OEM rubber
• Designed for 23mm (0.906 in) front stabilizer / sway bar diameter
• Grooved bore retains super grease for quiet, squeak-free performance
• Reduces body roll and improves cornering traction
• Resistant to oils, road grime, and weathering
• Black color finish
• Made in the USA
• Backed by Prothane's Lifetime Warranty

This kit is also compatible with larger-diameter high-performance aftermarket sway bars. A cost-effective suspension upgrade that delivers handling improvements comparable to installing a larger sway bar.
