Prothane 18-401-BL Rear Sway Bar End Link Bushing Kit Black

The Prothane 18-401-BL is a rear sway bar end link bushing kit engineered as a high-performance polyurethane replacement for the factory rubber end link grommets on the Toyota Corolla AE86 platform. This black-finish kit connects the rear stabilizer bar to the control arm, restoring and improving lateral chassis stability and sway bar effectiveness.

Over time, OE rubber end link grommets crack, rot, and lose their shape, reducing handling performance and allowing unwanted suspension flex. Prothane's polyurethane construction resists deterioration and maintains its shape far longer than rubber, delivering consistent suspension geometry and improved chassis feedback throughout the life of the part.

Key Features:

• Black polyurethane construction — same durometer and performance as Prothane's red urethane; color is a matter of preference
• Direct replacement design — engineered to fit the factory rear sway bar end link mounting points without modification
• Improved handling and stability — eliminates the flex and compliance of worn factory rubber bushings for more precise sway bar engagement
• Superior durability — polyurethane resists cracking, swelling, and degradation from road chemicals and the elements
• Made in the USA — manufactured by Prothane to exact specifications for resilience and performance
• Lifetime warranty — backed by Prothane's lifetime guarantee

Ideal for street driving, autocross, and track use, this kit is a cost-effective upgrade over OEM rubber components. Part number 18-401-BL is the black version; the equivalent red kit is 18-401.
