MIA's Description

The Hays Steel SFI Certified Flywheel; 157-Tooth; External Balanced is designed to withstand the rigor of high RPM and demanding racing conditions. It serves as an essential part of the clutch assembly, providing a reliable and balanced interface between the engine and transmission to ensure smooth power transfer and durability. Crafted from certified billet steel, this flywheel offers superior strength to resist breakage under extreme conditions. It features a precision-machined finish with a natural steel texture, maintaining its integrity during intense racing use. Installation requires moderate mechanical skill but no drilling of the flywheel is necessary as it is pre-drilled with standard clutch bolt patterns (Borg and Beck). It fits directly to the engine crankshaft using existing bolt holes for a hassle-free setup. This flywheel includes a manufacturer's limited 90-day warranty assuring quality and performance.
