SPEC 390 GT Aluminum Flywheel 1967-1969

SPEC flywheels are CNC manufactured at an unheard-of .001 tolerance. This precision manufacturing process ensures perfect balance and a perfectly flat bedding surface for the clutch disc, both of which also contribute to the ultimate in safety for competitive environments. All SPEC flywheels carry SFI certification. Provides a consistent and friction enhancing surface for the clutch disc. Also aids in proper inertia, which is determined by the flywheel weight.

To allow for specific inertia needs, SPEC flywheels are made in aircraft quality billet aluminum. The aluminum SPEC units are able to be rebuilt and feature a replaceable steel friction plate that is made from a friction- enhancing steel metal specially formulated for optimum clutch bedding and holding power. The aluminum materials provide a light weight option for all types of racing.
