Prothane 7-1166 Rear Sway Bar Bushing Kit 22mm Polyurethane

The Prothane 7-1166 is a rear stabilizer bar bushing kit designed for the C5 Corvette, replacing worn OEM rubber bushings with precision-molded polyurethane for improved handling response and long-term durability. This direct-fit kit is engineered for 22mm rear sway bars and is available in red or black.

Key Features:

• Polyurethane construction resists road salts, grime, oils, and weathering that degrade stock rubber bushings over time
• Grooved bore design retains Prothane Super Grease for quiet, squeak-free operation
• Firmer bushing material maintains a secure grip on the sway bar, reducing body roll and maximizing sway bar effectiveness
• Performance improvement comparable to installing a larger diameter sway bar — at a fraction of the cost
• Compatible with OEM 22mm rear sway bars as well as larger-diameter aftermarket high-performance bars
• Available in red or black to suit your preference
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

Over time, stock rubber sway bar bushings can warp, crack, or lose their grip on the bar, allowing unwanted movement that reduces anti-roll performance. Prothane polyurethane bushings hold their shape and grip far longer than rubber, ensuring consistent handling whether on the street or the track. Prothane Super Grease is included — proper lubrication during installation is essential for optimal, noise-free performance.
