RAM Billet Aluminum Flywheel, 21 Pounds (2008-2020 Challenger 5.7L & 6.1L HEMI)

All billet flywheels are not created equally! Make sure you are getting the features you pay for. RAM billet steel and aluminum flywheels are fully machined and assembled in house. 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 performance. That means when you get your RAM billet flywheel, it is already surface ground, already balanced, and ready to install out of the box. A key feature of RAM aluminum flywheels is the steel insert. A flywheel insert must have enough mass to wick heat away from the clutch without distorting. RAM uses a .250-inch thick insert that is riveted in before the flywheel is surface ground. This assures a parallel friction surface with no run out, and enough material to adequately wick the heat while maintaining flatness over time that thinner inserts simply cannot do. All RAM billet flywheels are SFI certified.
