Prothane 4-1113 Red 1" Front Sway Bar Bushing Kit

The Prothane 4-1113 is a red polyurethane front sway bar bushing kit designed as a direct upgrade over worn or soft OEM rubber stabilizer bar bushings. Engineered for a precise 1-inch (25.4mm) bar diameter, this kit restores and improves the performance of your front anti-roll bar — also commonly referred to as a stabilizer bar or sway bar — for noticeably sharper handling and reduced body roll.

Prothane's premium polyurethane compound is significantly more durable and dimensionally stable than factory rubber. Unlike rubber bushings that compress and deform over time, these polyurethane bushings maintain their shape and grip, keeping the sway bar firmly located for consistent, predictable cornering response. The grooved bore design is engineered to retain Prothane's supplied super grease, ensuring quiet, squeak-free operation throughout the bushing's life.

Key Features:

• Premium polyurethane construction — more durable and resilient than OEM rubber
• 1-inch (25.4mm) bore diameter — precisely sized for correct fitment
• Grooved bore design holds supplied super grease for quiet, long-lasting operation
• Reduces body roll and improves cornering traction over stock rubber bushings
• Red color for easy identification during installation and inspection
• Made in the USA with a Lifetime Warranty
• Sold as a complete kit

Upgrading to Prothane polyurethane sway bar bushings is a cost-effective way to extract more performance from your existing suspension. The improvement in lateral stiffness is comparable to installing a larger diameter sway bar, but at a fraction of the cost. Confirm your sway bar diameter prior to ordering, as bar sizes can vary by vehicle package.
