Prothane 8-1146 Polyurethane Sway Bar Bushing - Kit Front Rear

The Prothane 8-1146 is a front and rear sway bar bushing kit crafted from premium-grade polyurethane, engineered to outperform the soft factory rubber bushings on your stabilizer bar. By replacing worn or mushy OEM rubber, these bushings restore and enhance the effectiveness of your anti-roll bar, delivering tighter handling response and reduced body roll.

Key Features:

• Premium polyurethane construction — significantly more durable than stock rubber; resists breakdown from road grime, oils, and weathering
• Grooved bore design — holds Prothane's included Super Grease for smooth, quiet operation and long-lasting lubrication
• Precision-machined fit — engineered to exact OEM specifications for a direct-fit installation
• Reduces body roll — keeps the stabilizer bar firmly located, improving cornering grip and vehicle stability
• Available in red or black — choose the color that suits your build
• Also fits larger-diameter high-performance sway bars — ideal for upgraded aftermarket anti-roll bars
• Includes front and rear bushings — complete kit for a full stabilizer bar bushing refresh
• Lifetime warranty — backed by Prothane's guarantee against defects in materials and workmanship for the life of the vehicle under original ownership
• Made in the USA

Prothane polyurethane bushings provide a secure, consistent grip on the sway bar that rubber simply cannot match over time. Whether you're building a performance-focused street machine or simply want a more responsive, confident ride, the 8-1146 kit is a straightforward upgrade with lasting results.
