Prothane 4-1120 Front Sway Bar Bushing Kit 24mm Polyurethane Red

The Prothane 4-1120 is a front sway bar bushing kit designed as a direct upgrade over worn or soft factory rubber bushings. Manufactured from high-performance polyurethane, this kit delivers a firmer, more precise connection between the front stabilizer bar and the chassis — reducing body roll and improving handling responsiveness.

Over time, OEM rubber sway bar bushings can warp, crack, and lose their grip on the bar, causing the stabilizer to lose effectiveness. Prothane's polyurethane compound resists road grime, weather, oils, and general wear far better than rubber, ensuring the bushing maintains a secure grip on the bar throughout its service life. The result is a suspension that performs closer to a larger aftermarket sway bar without the added cost.

Key Features:

• 24mm bore diameter — sized for the factory front stabilizer bar (Tour Edition only)
• Grooved bore design — channels hold Prothane's Super Grease for quiet, squeak-free operation
• High-performance polyurethane construction — superior resistance to wear, oils, and weather versus OEM rubber
• Available in red or black — same durometer and performance in both colors; black version includes a small amount of graphite to further aid in squeak prevention
• Includes Prothane Super Grease — proper lubrication at installation is essential for noise-free performance
• Made in the USA
• Lifetime warranty against defects in materials and workmanship for the original purchaser

Installation is straightforward and can typically be completed with standard hand tools. For best results, apply the included Super Grease generously to all bushing surfaces during installation to prevent noise and ensure long-term performance.
