Prothane 8-1141-BL Rear Sway Bar Bushing Kit 11mm Black Polyurethane

The Prothane 8-1141-BL is a rear sway bar bushing kit designed for the Honda Civic, fitting an 11mm (0.43 inch) diameter rear sway bar. Molded from high-performance polyurethane, these bushings deliver a significant durability and handling advantage over the factory rubber units they replace.

OEM rubber sway bar bushings are prone to warping and cracking over time, causing the sway bar to lose its grip and reducing the suspension's ability to control body roll. Prothane's polyurethane construction resists breakdown from road grime, weather, and oils, maintaining a secure, consistent grip on the bar throughout the life of the vehicle.

Key Features:

• Polyurethane construction — far more durable and resilient than factory rubber bushings
• 11mm (0.43 in.) bar diameter — precision-fit for the correct sway bar size
• Black finish with a small amount of graphite blended into the polyurethane to help minimize squeaking
• Does not warp or deflect under cornering load, helping maintain proper suspension geometry
• Snug sway bar grip delivers handling performance comparable to installing a larger sway bar
• Sold as a pair — complete kit for one axle
• Includes Prothane Super Grease — apply during installation to prevent squeaking and ensure long service life
• Lifetime warranty — backed by Prothane against defects in materials and workmanship for as long as the original purchaser owns the vehicle

During installation, be sure to apply the included Prothane Super Grease to the bushing bore, as the sway bar rotates inside the bushing during suspension movement. Proper lubrication at install is the most effective way to prevent any squeaking and maximize bushing longevity.
