Prothane 6-401 Rear Sway Bar End Link Bushing Kit

The Prothane 6-401 is a rear sway bar end link bushing kit designed as a direct-fit replacement for worn OEM rubber components. Manufactured from high-durometer polyurethane, this kit restores and improves the connection between the sway bar and the control arm, delivering tighter handling response and improved chassis stability.

Factory rubber end link bushings degrade over time due to exposure to heat, oil, and road grime, resulting in vague steering, unwanted body roll, and suspension noise. Prothane's polyurethane construction resists these elements far better than rubber, providing a longer-lasting solution that maintains consistent suspension geometry.

Key Features:

• High-durometer polyurethane construction for superior durability over OEM rubber
• Grooved bores retain supplied super grease for quiet, rattle-free operation
• Enhances effectiveness of the factory stabilizer bar
• Direct-fit replacement — no modification required
• Resistant to oil, heat, and road contaminants
• Available in red or black
• Backed by Prothane's lifetime warranty
• Made in the USA

This kit is specifically designed for the rear end links of the sway bar. For best results, replace end link bushings on both sides simultaneously using components of the same material.
