There is a difference in aftermarket flywheels! RAM billet flywheels are produced completely in house using computer controlled equipment to provide you with a flywheel that is properly machined within .001 tolerances, surface ground to allow the best mating friction surface for the disc to seat against and guard against runout, and precision balanced on a computer controlled balancer to within oz/in of the factory balance specification. In other words, a RAM billet flywheel is ready to run right out of the box.
Note: Billet steel flywheels are best used on street / strip applications & billet aluminum flywheels on race applications. All billet flywheels from Ram are SFI certified.
