The Speedmaster Ford FE 390 427 428 1.76 Ratio Aluminum Shaft Mount Roller Rocker Arm Set is a performance valvetrain component designed for classic Ford FE big-block engines. This roller rocker arm set features an aluminum construction for reduced weight and improved durability, utilizing a shaft mount design for secure, stable installation on your engine block.
This 1.76 ratio rocker arm set is engineered to enhance valve actuation efficiency across Ford FE displacement variants—the 390, 427, and 428 cubic-inch platforms. The roller design minimizes friction at the valve stem interface, supporting higher RPM capability and more consistent valve timing. Installation is straightforward for engine builders and restoration enthusiasts working on classic muscle cars, hot rods, and street performance builds.
