Prothane 7-1142-BL Sway Bar End Link Bushing Kit Black Polyurethane - Rear 19mm

The Prothane 7-1142-BL is a rear sway bar and end link bushing kit designed for 19mm stabilizer bars. Engineered from premium-grade polyurethane, these bushings are a direct upgrade over the soft, deteriorating rubber bushings found on factory suspensions. Polyurethane delivers a firmer, more consistent interface between the sway bar and chassis, helping to restore and improve anti-roll performance.

Key Features:

• Precision-grooved bores engineered to retain Prothane Super Grease for quiet, squeak-free operation
• Premium polyurethane construction — significantly more durable than OEM rubber and resistant to road grime, oils, and weather
• Maintains its shape and grip over time — will not warp, crack, or hollow out like rubber under prolonged use
• Black color — includes a small graphite content in the polyurethane compound which aids in noise reduction
• Performance equivalent to a larger sway bar — tighter bushing fit restores sway bar effectiveness and reduces body roll
• Includes Prothane Super Grease — apply thoroughly during installation to ensure proper lubrication and prevent squeaking
• Lifetime warranty — Prothane guarantees this product to be free of defects in materials and workmanship for the life of the original purchaser's vehicle

Stock rubber sway bar bushings are prone to warping and cracking over time, allowing the bar to shift and lose its ability to keep tires planted during cornering. Replacing them with Prothane polyurethane bushings restores the sway bar's effectiveness and delivers a noticeable improvement in handling feel. Sold as a kit and available in black finish.
