SFI-Approved Billet Steel Flywheels
All billet flywheels are NOT created equal! Every RAM True Balance flywheel is turned, drilled, and tapped on CNC equipment from SFI-certified billet steel. Each flywheel is precision ground parallel to the crank flange and to the proper RMS finish for optimum mating of the friction disc. If operating in high-performance, high-RPM applications, a billet steel flywheel is recommended over factory cast flywheels, cutting down on rotating weight and further increasing driveability.
