Product Details
The body of this Fidanza flywheel is made from Billet 6061 T6 or 2024 T4 aluminum, which is 40-60 percent lighter than the original stock unit. This significant weight reduction lowers the moment of inertia (MOI), allowing your engine to rev up faster and respond more quickly to throttle inputs. This can free up additional horsepower that was previously being used to spin a heavier flywheel. The friction surface is a heat-treated, replaceable 1050 steel ring gear, ensuring a solid grip for your clutch and long-term durability.
Fidanza uses military-spec fasteners for reliability and strength, and most applications include stepped dowels for precise alignment. The friction plate is also replaceable, meaning you don't have to replace the entire flywheel when it's time for a new clutch. This makes it a well-built and practical choice for your Triumph TR4 or TR4A.
