Prothane 6-1128 Polyurethane Stabilizer Bar Bushing 1" ID 3.5" Height

Upgrade your suspension performance with the Prothane 6-1128 polyurethane stabilizer bar bushing, engineered as a direct replacement for soft, worn OEM rubber bushings. Designed for sway bars (also known as anti-roll bars or stabilizer bars), this bushing restores and enhances handling precision by eliminating the flex and slop that degrades over time in stock rubber components.

Key Features:

• 1" Inner Diameter — precision fit for compatible stabilizer bar applications
• 3.5" Height — end-to-end (E/E) measurement for proper installation clearance
• Polyurethane construction — significantly firmer than OEM rubber for improved suspension response and reduced body roll
• Grooved bore design — engineered to retain Prothane Super Grease, ensuring quiet, squeak-free operation
• Compatible with larger diameter high-performance sway bars — versatile fitment for upgraded aftermarket bar applications
• Direct OEM replacement — bolt-in installation with no modifications required

Prothane polyurethane bushings are a proven upgrade for drivers seeking sharper steering feedback, reduced chassis flex, and longer-lasting suspension components. Unlike OEM rubber, polyurethane resists oil, ozone, and general weathering to maintain consistent performance over time. The Prothane 6-1128 is part of Prothane's comprehensive suspension bushing lineup and is designed to deliver a noticeable improvement in handling with minimal installation effort.
