PERFORMANCE CHROMOLY FLYWHEEL [LSF18169]

ClutchMax Performance Chromoly Flywheels are developed to provide ideal balance of street and track driving and they are designed to compliment virtually all types of clutches. All flywheels are engineered using the latest CAD technology and advanced Finite Element Analysis (FEA) software to achieve the best results. Optimal weight reduction and dynamic computer balancing provide greatly improved performance and driving experiences. They are lighter, stronger, safer, and more affordable than ever.   Type:  Performance Lightweight Flywheel Material:  One-piece solid 4140 chromium-molybdenum (chromoly) forged steel Ring Gear Count:  139 Flywheel weight:   11.63 lbs (5.275 kg) Key Features: 25% weight reduction for ideal balance of street and track driving 4140 chromium molybdenum forging is stronger and more durable than billet steel, aluminum or cast iron. Integral ring gear is induction-hardened for maximum gear life Optimal mass distribution for strength, exceptional heat dissipation and reduced inertia CAD-designed, CNC-machined and computer balanced for quality and precision Balanced within 0.100 oz for smooth operation at all RPM range Meets or exceeds highest industry standard SFI spec 1.1 Black zinc plated for protection against corrosion Proudly engineered and developed in the U.S.A.   VEHICLE APPLICATION Fits March/2015 - 2018 Mazda MX-5 Miata (2.0L Skyactive-G 4cyl; ND)
