Prothane 1-1126-BL Black Polyurethane Rear Sway Bar Bushing Kit 19mm

The Prothane 1-1126-BL is a black polyurethane rear sway bar bushing kit designed as a direct replacement for the worn, soft OEM rubber bushings on the 19mm rear stabilizer bar. Upgrading to polyurethane sway bar bushings restores and improves suspension performance, helping maintain maximum tire contact with the road surface and reducing unwanted body sway.

Stock rubber sway bar bushings tend to deteriorate over time, especially under demanding off-road use. Once they crack, split, or rot, the sway bar loses its secure mount, leading to an annoying rattle, uneven tire wear, and compromised handling. These firm polyurethane bushings grip the sway bar securely, eliminating excessive bar movement and restoring confident suspension response.

Key Features:

• Black polyurethane construction with a small graphite content for additional resistance to squeaking
• Split design allows for easy installation — no need to remove the entire sway bar
• Grooved bore designed to retain Prothane Super Grease for smooth, quiet long-term operation
• Fits 19mm (0.74") rear stabilizer bars — measure your bar before installation to confirm fit
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship for the life of original ownership

The black color variant shares the same durometer (hardness rating) as Prothane's red bushings, delivering identical performance. The included Super Grease should be applied at installation to ensure quiet, long-lasting operation. Kit includes a pair of rear sway bar bushings.
