The SPEC steel flywheel is specified for SR20DET applications in Nissan S13 and S14 chassis, providing a direct replacement for the factory flywheel in those configurations. Its steel construction is explicit in the product name and the overview focuses on fitment: it matches SR20DET bolt patterns for S13/S14 use. Confirm engine and chassis compatibility before installation.
