Lightweight Steel Flywheel

4140 STEEL:

Clutch Masters’ steel flywheels are precision machined on our CNC machines to exact tolerances for a perfect fitment on your application. Our steel flywheels are machined from 1045 or 4140 billets that are sourced from US manufacturers and are guaranteed free of impurities or defects. Some of our very popular ultra-light steel twin disc flywheels used for racing are forged chromoly pieces that are then finished to exact tolerances. As our steel flywheels are being machined, a Clutch Masters craftsman continuously checks each flywheel throughout it’s build to make sure it has been machined to exact specifications and every critical measurement is within tolerance. All of our steel flywheels receive a black oxide coating to ensure they stay rust free for the life of the flywheel. After they are coated they are laser engraved with our logo and part number, boxed up and ready for your project! All steel flywheels are SFI certified for use in all sanctioned racing bodies.
