Prothane 7-1109 Front Sway Bar Bushing Set GM 1-1/8" OD Polyurethane 1973-1991

The Prothane 7-1109 front stabilizer bar bushing set is a direct-replacement polyurethane upgrade for GM vehicles from 1973 through 1991. Designed to replace the factory rubber bushings that soften and deteriorate over time, these bushings restore and enhance the effectiveness of your OEM stabilizer (anti-roll/sway) bar, reducing body roll and improving overall handling precision.

Manufactured from Prothane's signature firm polyurethane compound, these bushings outperform stock rubber in durability, resistance to oil and road chemicals, and long-term shape retention. Each bushing features a 1-1/8" outer diameter and a precision-machined grooved bore designed to retain Prothane's proprietary super grease, ensuring smooth, quiet operation even under aggressive driving conditions.

Key Features:

• Direct-fit replacement for GM front stabilizer bar bushings (1973–1991)
• 1-1/8" OD — fits standard and compatible high-performance sway bars
• Grooved bore design holds Prothane super grease for quiet, squeak-free performance
• Firm polyurethane construction resists compression set, oil, and harsh weather

• Also compatible with larger-diameter high-performance aftermarket sway bars of matching OD
• Made in the USA

The Prothane 7-1109 is an ideal suspension upgrade for daily drivers and performance builds alike, delivering tighter, more responsive steering feel and extended service life over factory components. Prothane super grease is included for hassle-free installation.
