Prothane 16-1101-BL Front Sway Bar Bushing Kit 20mm Black Polyurethane

The Prothane 16-1101-BL is a front stabilizer bar bushing kit designed as a direct performance upgrade over stock rubber bushings. Engineered from firm polyurethane, these bushings deliver a more secure grip on the sway bar to reduce body roll, improve traction, and sharpen handling response.

Why Upgrade to Polyurethane?

OEM rubber bushings wear over time, warping and cracking under exposure to road grime, oils, and weather. When rubber bushings lose their grip on the bar, sway bar effectiveness is compromised — leading to increased body roll and reduced cornering stability. Prothane polyurethane bushings resist degradation and maintain their shape and grip for the life of the vehicle.

Key Features:

• 20mm bore diameter — fits the OEM front stabilizer bar
• Black polyurethane construction — formulated with a small amount of graphite to help reduce noise
• Grooved bore design — retains Prothane Super Grease for smooth, quiet operation
• Firmer than OEM rubber for improved sway bar performance — similar effect to installing a larger diameter bar
• Resistant to oils, road grime, and weathering
• Includes Prothane Super Grease for proper installation lubrication
• Lifetime Warranty — backed by Prothane for the life of the original purchaser's vehicle
• Made in the USA

These bushings are also compatible with larger diameter aftermarket high-performance sway bars. For best results and to prevent squeaking, apply the included Super Grease thoroughly during installation.
