Fidanza 59-67 Jaguar Mark II 3.8L / 61-64 XKE 3.8L Aluminum Flywheel

This Fidanza aluminum flywheel is built with a billet 6061 T6 or 2024 T4 aluminum body, making it 40-60% lighter than the original stock unit. This significant weight reduction lowers the moment of inertia (MOI), which translates directly into quicker acceleration and a more responsive throttle. It’s a smart choice if you’re looking to free up some extra horsepower and improve the overall feel of your Jaguar’s drivetrain.

The friction plate is heat-treated for optimal grip and long wear, and it’s designed to be replaceable, meaning you don’t have to replace the entire flywheel when the friction surface eventually wears down. Fidanza also includes a hardened 1050 steel ring gear that bolts on, ensuring reliability. For added security and precision, military-spec fasteners are used throughout the assembly, giving you confidence in the part's durability and performance under demanding conditions.

This flywheel is a direct replacement for several Jaguar models, including the 1961-1966 3.8, 1959-1961 Mark IX, 1962-1964 Mark X, 1958-1961 XK150, and 1961-1964 XKE. When installing, ensure you follow the manufacturer's recommended procedures for proper seating and torque specifications to get the most out of its lightweight design.
