Fidanza 59-61 MG MGA/B Lightweight with Replaceable Friction Plate

When you're looking to get more out of your 1959-1961 MG MGA, especially if you're rebuilding the drivetrain or upgrading the clutch system, a lighter flywheel can make a notable difference. This aluminum flywheel from Fidanza is designed to reduce rotational mass, which means your engine can rev up faster and respond more quickly to throttle inputs. It's a popular choice for MGA owners looking for that improved acceleration feel.

Fidanza builds these flywheels with a billet 6061 T6 or 2024 T4 aluminum body, making them significantly lighter—often 40-60 percent less than the stock unit. This lower moment of inertia (MOI) directly translates to quicker acceleration. For added durability and performance, the friction plate is heat-treated for optimal grip and long life, and it's a bolt-on, replaceable part. This means you can service the friction surface without needing to replace the entire flywheel, which is a smart feature for long-term ownership. They also use military-spec fasteners, ensuring reliability for the critical job of holding the flywheel securely to the crankshaft.

This flywheel is designed as a direct replacement, so it should fit right into your MGA's drivetrain. The stepped dowels, common on most applications, help ensure proper alignment during installation.
