Prothane 6-1128-BL Sway Bar Bushing 1" ID 3.5" Height Black Polyurethane

The Prothane 6-1128-BL is a black polyurethane stabilizer bar bushing designed as a direct replacement for worn or soft OEM rubber bushings. With a 1-inch inner diameter and 3.5-inch height, this bushing delivers a firmer, more responsive feel that restores and enhances the performance of your vehicle's sway bar (also known as an anti-roll bar or stabilizer bar).

Stock rubber bushings tend to deteriorate over time, becoming soft and allowing excessive sway bar movement. Prothane's polyurethane compound resists compression and deformation far better than rubber, translating to improved handling, reduced body roll, and more predictable cornering behavior.

Key Features:

• 1" Inner Diameter — fits standard and performance sway bar applications
• 3.5" Height — end-to-end design for secure, stable mounting
• Grooved Bore — designed to retain Prothane Super Grease for smooth, quiet operation
• Black Polyurethane Construction — superior durability and resistance to oils, chemicals, and UV exposure versus OEM rubber
• Also compatible with larger-diameter high-performance sway bars — check Prothane's full lineup for oversized fitments
• Manufactured in the USA by Prothane, a trusted name in performance polyurethane suspension components

Installation is straightforward with basic hand tools. For best results and quietest operation, apply Prothane Super Grease (included or available separately) to the grooved bore before installation. Part number 6-1128-BL ships in black.
