Prothane 4-1106-BL Black 13/16" Front Sway Bar Bushing Kit B-Body

The Prothane 4-1106-BL is a black polyurethane front sway bar bushing kit designed for Chrysler/Dodge B-Body vehicles (1973–1979) equipped with a 13/16" diameter stabilizer bar. This kit is a direct upgrade over the factory rubber bushings, delivering improved handling response and long-term durability.

Stock rubber sway bar bushings soften and deflect under load, allowing excess body roll and vague steering feel. Prothane's firm polyurethane compound resists compression and deformation, restoring the full effectiveness of your OEM or performance anti-roll bar. The bores are precision-grooved to retain Prothane's super grease, ensuring quiet, squeak-free operation throughout the bushing's service life.

Key Features:

• Made from firm, durable polyurethane — a significant upgrade over soft OEM rubber
• Grooved bore design holds Prothane super grease for quiet, long-lasting operation
• Designed for 13/16" diameter front stabilizer (sway) bars
• Black finish to blend with factory chassis components
• Compatible with B-Body front subframe/chassis mounting points (1973–1979)
• Also compatible with larger-diameter high-performance aftermarket sway bars (where applicable)
• Direct-fit replacement — no modifications required

Prothane polyurethane suspension components are engineered to exact resiliency and performance specifications, making them a trusted choice for enthusiasts restoring or upgrading classic Mopar muscle cars and B-Body platforms.
