Product Details
SPEC is known for making well-built drivetrain components, and this aluminum flywheel is a solid option for your 1962-1967 MG MGB or 1956-1959 MG MGA. A lighter flywheel changes how your engine revs. Because this flywheel is made from aluminum, it weighs significantly less than the stock cast iron unit. This means your engine will spin up faster when you accelerate, giving you a more responsive feel. It also helps the engine slow down more quickly when you lift off the throttle.
This flywheel is designed as a direct replacement for your original, so it fits right in place. The reduced mass not only improves engine response but can also help with heat dissipation compared to heavier steel or iron flywheels. If you're looking to get a bit more pep out of your classic MG's engine, especially if you're doing a clutch job, this aluminum flywheel is a great way to go. It's a noticeable change that makes the car feel more eager.
