Prothane 6-1903-BL Ford C-Bush Polyurethane Complete Bushing Set 1966-1979 Black

The Prothane 6-1903-BL is a complete polyurethane C-bushing set designed for classic Ford vehicles from 1966 to 1979. These bushings replace the factory rubber subframe C-channel bushings that isolate the front subframe from the unibody, restoring proper alignment geometry and dramatically improving chassis response.

Prothane's proprietary polyurethane compound is significantly firmer than OEM rubber, resisting compression, deflection, and deterioration from oil, grease, and road chemicals. The result is tighter, more predictable handling with reduced steering vagueness and improved front-end stability — without sacrificing drivability.

Key Features:

• Complete C-bushing set for full front subframe restoration
• Manufactured from Prothane's high-durometer polyurethane compound
• Black finish (part suffix -BL)
• Resists oil, grease, ozone, and road chemicals
• Firmer than OEM rubber for improved chassis feedback and handling precision
• Direct OEM replacement fitment — no modifications required
• Includes all necessary bushings for a complete subframe bushing service
• Lifetime warranty against defects in materials and workmanship

Designed as a direct factory replacement, the Prothane 6-1903-BL installs using standard hand tools and is an ideal upgrade during any front-end restoration on classic Ford Mustangs, Falcons, Fairlanes, Torinos, and other Fox/unibody platform Ford models of the era. Grease fittings or supplied grease should be used during installation for maximum longevity.
