Prothane 12-1105-BL Rear Sway Bar Bushing Kit 19mm Black Polyurethane

The Prothane 12-1105-BL is a black polyurethane rear sway bar bushing kit designed as a direct upgrade over worn or soft OEM rubber bushings. Engineered for a precise 19mm rear stabilizer bar, this kit restores and enhances the sway bar's anti-roll performance for improved cornering stability and handling response.

OEM rubber stabilizer bar bushings are prone to warping, cracking, and losing their grip on the bar over time — causing the sway bar to lose effectiveness. Prothane's polyurethane compound resists degradation from road grime, weather, and oils, maintaining a secure, consistent grip on the sway bar throughout its service life.

Key Features:

• Fits 19mm rear sway bar (stabilizer bar / anti-roll bar)
• Durable polyurethane construction — resists oil, weather, and road grime
• Grooved bore design retains Prothane Super Grease for quiet, squeak-free operation
• Black color with graphite-infused compound for additional noise reduction
• Firmer than OEM rubber for improved handling and reduced body roll
• Backed by a lifetime warranty
• Includes Prothane Super Grease lubricant
• Available in black (12-1105-BL) or red (12-1105)

Installing Prothane polyurethane sway bar bushings provides a performance boost comparable to fitting a larger sway bar — maximizing the effectiveness of your existing OEM or aftermarket stabilizer bar. Be sure to apply the included Super Grease during installation for optimal performance and noise-free operation.
