Prothane 7-1140-BL Rear Sway Bar Bushing Kit 22mm Black Polyurethane

The Prothane 7-1140-BL is a rear stabilizer bar bushing kit designed as a direct upgrade over worn or soft OEM rubber bushings. Manufactured from firm polyurethane, these bushings restore and improve sway bar performance, reducing body roll and sharpening handling response.

Worn rubber sway bar bushings allow the bar to shift under load, diminishing its ability to control body roll and maintain tire contact with the road surface. Prothane's polyurethane compound maintains its shape and grip far longer than factory rubber, delivering consistent anti-roll performance over the long term. This kit fits the 22mm rear stabilizer bar and is finished in black.

Key Features:

• Polyurethane construction — significantly firmer and more durable than OEM rubber bushings
• Grooved bore design — engineered to retain Prothane's super grease for quiet, squeak-free operation
• 22mm bore diameter — precise fit for the factory rear sway bar
• Black finish (part suffix -BL) — also available in red (part #7-1140)
• Sold as a pair — complete kit for a full rear sway bar bushing replacement
• Made in the USA — backed by Prothane's Lifetime Warranty

Upgrading to Prothane polyurethane sway bar bushings is one of the most cost-effective suspension improvements available, delivering handling characteristics comparable to installing a larger-diameter sway bar at a fraction of the cost.
