| (9lbs) Ultra Light flywheels are CNC-machined from lightweight 6061-T6 billet aluminum. These flywheels can be used with any stock or aftermarket clutch setup. The Ultra Light aluminum flywheels have some key advantages over stock and other aftermarket units. Machining tolerances are extremely important when making a flywheel. Eccentricity, parallelism, and the step height (which is critical to proper clutch break-in and engagement) are kept to within .0015", the most accurate in the industry! Dowel pins are hardened steel units and all hardware is grade 8 (grade 10.9 metric equivalent), the highest grade of fastener available today. Torque plates are also included in applications where required and flywheels are checked for zero-balance before shipping. Our friction insert (heat shield) is a specially-treated replaceable steel insert utilizing a unique ferritic nitrocarburizing process that makes them resistant to aggressive ceramic clutches, as well as keeping the co-efficient of friction high. In many flywheels on the market, the co-efficient of friction is compromised for hardness. Not so in these units. All inserts are CNC-machined instead of being quickly ground like most aftermarket units, and are replaceable on all the models we make if ever damaged. Another benefit to these aluminum flywheels is the fact that they can be serviced, which is not the case with chromoly flywheels. All ring gears are heated before they are placed on the flywheel and then cooled to shrink them in place. In addition they are bolted to ensure the ring gear will never slip or come off the flywheel under any circumstances. The flywheel weights are chosen very carefully. They are the perfect balance of strength and light weight. Because of their light weight, energy normally used to turn the heavy stock steel flywheel is now used to turn your drive wheels. In addition, the reduced mass allows the engine to rev faster and get you into your power band more quickly. For turbo cars this is an even greater advantage, allowing the turbos to kick in faster since the engine is revving more quickly. These flywheels are the perfect choice for street use, drag racing, autocross, and road race events. Horsepower gains for aluminum flywheels can average from 10 to 30 horsepower over stock levels at the drive wheels
