Product Description

The Clutch Masters FW-H2B-AL is a lightweight billet aluminum flywheel designed specifically for Honda H2B swap builds -- mating an H-series engine (H22 2.2L VTEC or H23 2.3L) to a B-series transmission. At just 8 pounds, this flywheel provides a dramatic reduction in rotating mass compared to the factory unit, delivering faster engine revving, sharper throttle response, reduced turbo lag on forced induction builds, and improved mid-range torque on naturally aspirated setups. The reduced rotational inertia also decreases drag on the crankshaft, allowing the engine to accelerate more freely through the rev range.

CNC machined from high-grade billet aluminum and precision balanced, this flywheel is SFI certified to meet the safety standards required for motorsport and competition applications. Clutch Masters notes that aluminum flywheels are primarily recommended for race applications where minimum rotating mass is the priority -- the lighter weight will produce more gear noise than a steel flywheel, which may not be suitable for daily street driving. For street-driven H2B builds where noise and drivability are a concern, Clutch Masters recommends their steel flywheel alternative. Years of R&D have given Clutch Masters the firsthand experience to select the optimal materials and manufacturing processes for flywheels that meet the demands of both professional racers and serious enthusiasts. Founded in the 1980s, Clutch Masters is a leading manufacturer of high-performance clutch systems and drivetrain components.
