Prothane 1-1124 Rear Sway Bar Bushing Kit 9/16in Polyurethane Red

The Prothane 1-1124 is a rear stabilizer bar bushing kit designed as a firm, long-lasting upgrade over soft factory rubber bushings. Engineered from premium-grade polyurethane, these bushings maintain a secure, consistent grip on the sway bar and resist the warping, cracking, and deterioration that cause OEM rubber bushings to fail over time.

Polyurethane outperforms rubber in demanding environments — it does not break down from road grime, moisture, oils, or road salts. The result is improved handling response and reduced body roll, delivering performance comparable to installing a larger-diameter sway bar at a fraction of the cost.

Key Features:

• Material: Premium polyurethane construction — firmer and more durable than OEM rubber
• Grooved bore design retains Prothane Super Grease for smooth, quiet operation
• Bar diameter: 9/16 inch (14.28mm)
• Resists road salts, oils, weather, and road grime that degrade rubber
• Maintains shape and grip over the life of the vehicle — will not hollow out or warp
• Includes Prothane Super Grease lubricant and installation instructions
• Lifetime warranty against defects in materials and workmanship
• Made in the USA

Available in red or black. Note: black variants include a small amount of graphite blended into the polyurethane, which can further assist in reducing squeaking. Regardless of color, proper greasing at installation is the most effective way to ensure quiet, long-lasting performance.
