Introducing our high-quality Engine Flywheels. Light flywheels provide significantly improved engine response and acceleration by compromising drivability. XACT flywheels are designed for improving engine response, strength and affordability. As engine performance levels increase, stronger flexplates become necessary. Until this point, stronger flexplates meant thicker flexplates. This works, but it adds unwanted weight and prohibited the flexplates from working as it was designed. Flexplates are designed to provide a protection against converter/transmission run-out or OEM misalignment, which will cause transmission and/or converter failure. A rigid flexplate gives no protection. The ultimate design for a flexplate is extreme strength, flexibility and minimal weight. Crafted with precision and engineering excellence, our engine flywheels are made from durable materials, such as cast iron or forged steel, to withstand the rigors of engine operation. They are specifically designed to connect the engine crankshaft to the transmission input shaft, allowing for the transfer of power and torque.
