Prothane 12-1104-BL Front Sway Bar Bushing Kit 21mm Black Polyurethane

The Prothane 12-1104-BL is a front sway bar bushing kit designed for the 2004–2005 Mazda 3, replacing the factory rubber bushings with high-performance black polyurethane for improved handling and long-lasting durability. This kit fits a 21mm (0.83") front stabilizer bar.

Stock rubber sway bar bushings wear out, warp, and lose their grip on the bar over time, leading to increased body roll, clunking, and reduced cornering performance. Prothane polyurethane bushings maintain a firm, secure grip on the sway bar, keeping it properly located to maximize the bar's effectiveness and improve handling response.

Key Features:

• Direct-fit replacement for the front sway bar on 2004–2005 Mazda 3
• Fits 21mm (0.83") diameter front stabilizer bars
• Made from polyurethane — resists breakdown from road grime, weather, and automotive fluids
• Grooved bores designed to retain Prothane Super Grease for quiet, squeak-free operation
• Black color includes a small amount of graphite blended into the polyurethane for added squeak resistance
• Maintains consistent sway bar position to reduce body roll and improve cornering traction
• Performance comparable to upgrading to a larger sway bar
• Made in the USA
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Kit includes polyurethane bushings and Prothane Super Grease. Proper lubrication at installation is recommended for best performance and noise-free operation.
