Prothane 12-1101-BL Black Polyurethane Front Sway Bar Bushing Kit 19.04mm

The Prothane 12-1101-BL is a black polyurethane front sway bar bushing kit designed to replace worn OEM rubber stabilizer bar bushings. Engineered with a precise 19.04mm (0.75") bore diameter, these bushings deliver a firm, secure grip on the front sway bar — restoring and enhancing handling performance that stock rubber simply cannot match.

Why Upgrade from Rubber?

OEM rubber sway bar bushings deteriorate over time, warping and cracking under the stress of road grime, oil exposure, and weather. As they lose their grip on the bar, your stabilizer becomes less effective — resulting in increased body roll, reduced traction, and clunking noises. Prothane's polyurethane compound resists breakdown from these elements and maintains its shape and grip throughout the life of the vehicle.

Key Features:

• 19.04mm (0.75") bore diameter — precision fit for OEM sway bar diameter
• Black polyurethane construction with graphite additive for reduced squeaking
• Grooved bore design retains Prothane Super Grease for quiet, long-term operation
• Maintains a tight grip on the sway bar — delivers handling improvement comparable to installing a larger sway bar
• Resistant to road grime, petroleum oils, and weather degradation
• Includes Prothane Super Grease packet for proper lubrication at install
• Lifetime warranty — backed by Prothane against defects in materials and workmanship
• Available in black (12-1101-BL) or red (12-1101)

Proper installation requires applying the included Super Grease to the bushing bore before mounting to ensure quiet, long-lasting operation. This kit is a direct, performance-oriented replacement for the factory front sway bar bushings.
