1933 Ford Model 46 T5 Flywheels
A lightweight aluminum flywheel robs less horsepower from your flathead and will allow it to rev and respond more quickly. This high quality flywheel is machined from aluminum and has a steel insert friction surface. It's best suited for high performance, supercharged or race oriented flatheads.
Will accept 10.5" and 11" Ford pressure plates, 10" and 10.5" Long, and 10.5" Borg & Beck Diaphram pressure plates.
