What is the main benefit of a lighter flywheel like this one?

A lighter flywheel reduces the engine's rotational mass. This allows the engine to rev up more quickly and respond faster to throttle inputs, improving acceleration.

Is the friction surface replaceable on this flywheel?

Yes, this flywheel has a replaceable hardened steel ring gear. The friction plate itself is also designed to be replaceable, allowing for easier servicing.

Does this flywheel come with all the necessary hardware for installation?

This flywheel uses military-spec fasteners for reliability. It is recommended to check the product's included parts list or consult the manufacturer's installation guide for specific hardware details.

MG MGB 1968-1980

Product Details

Fidanza is known for making well-built aluminum flywheels that help engines rev up faster. This particular flywheel is made for your 1968-1980 MG MGB with the 1.8L engine. It's designed to reduce rotational mass, which means your engine can spin up more quickly, giving you a noticeable improvement in acceleration and throttle response. This is a direct replacement for your stock flywheel, making the swap straightforward.

This flywheel uses a billet 6061 T6 or 2024 T4 aluminum body, which is 40-60 percent lighter than the original cast iron unit. That significant weight reduction lowers the moment of inertia, allowing the engine to respond more eagerly to throttle inputs. It also features a heat-treated friction plate for a solid grip and long life, and the ring gear is made of hardened 1050 steel and can be replaced if needed. Fidanza also uses military-spec fasteners to ensure reliability.

Because this is a lighter flywheel, you might notice your engine idles a bit differently than before, and it may take a little practice to get used to the quicker revving. It's a popular choice for MGB owners looking to free up some extra performance from their engine.
