RAM billet steel flywheels are recommended as a replacement for factory cast flywheels in high performance and racing vehicles.

Cast flywheels are not explosion proof and can be dangerous when used in high performance applications at higher RPMs. RAM billet steel flywheels are CNC machined from certified materials and exceed SFI specifications.

After machining, the flywheels are balanced ground parallel to the crankshaft mounting surface, ensuring minimum run-out and the optimum mating surface for the clutch disc.

Use steel flywheels in heavier drag race cars or for the best drive-ability in street driven vehicles.

The flywheel accepts one half of the load of the clutch system. To realize the potential of the clutch system, the flywheel must be flat, parallel to the crankshaft flange, properly surface ground for maximum friction compatibility with the clutch disc, and balanced.

Dyno testing proves that flywheel balance is critical to achieving maximum engine service. Every RAM flywheel is dynamically balanced to within ½ ounce/inch of the factory specification.

RAM aluminum flywheels have a .250 inch thick steel friction insert to handle the heat generated under extreme conditions, while allowing resurfacing without the need to replace the insert.

All RAM flywheels are manufactured from SFI certified materials in their South Carolina facility.

For over 40 years, RAM has produced the world's top performing competition and street performance clutch systems. They have developed, improved, and produced in house, tried and true clutch components and systems that provide the highest performance value.

Today, every RAM product incorporates critical features that are absent from many of the products of those who choose to compete with RAM.

Warranty information: RAM flywheels are STRICTLY FACTORY WARRANTY ONLY. Customer must return the unit to RAM for evaluation and inspection.
