Prothane 6-401-BL Rear Sway Bar End Link Bushing Kit Black

The Prothane 6-401-BL is a rear sway bar end link bushing kit engineered as a high-performance polyurethane replacement for worn factory rubber end link grommets. Designed for the Ford Escort and related platforms (1990–1996), this kit restores critical sway bar-to-control-arm connection integrity, improving chassis stability, cornering response, and overall suspension feel.

OEM rubber end link grommets crack, rot, and compress over time, introducing unwanted slop into the suspension and degrading handling precision. Prothane's polyurethane bushings are significantly firmer and more resistant to heat, oil, and road grime than stock rubber components, ensuring long-lasting performance without premature deterioration.

Key Features:

• High-durometer polyurethane construction for superior durability over OEM rubber
• Black color finish (BL suffix)
• Direct-fit replacement — no modification required
• Includes all necessary bushings, washers, and grommets for complete end link restoration
• Designed to accept super grease for quiet, rattle-free operation
• Made in the USA and backed by Prothane's Lifetime Warranty

Upgrading to Prothane polyurethane end link bushings reduces suspension flex, improves road feedback, and helps maintain consistent alignment geometry during spirited driving. It is recommended to replace both sides simultaneously using the same bushing material for balanced suspension performance.
