Clutch Masters 05-08 Audi S4 (B7) 4.2L Steel Flywheel

Every Clutch Masters flywheel is proudly designed and manufactured in the USA. Flywheels are first designed in CAD and are then precision CNC machined in house in one of or Haas CNC lathes out of 1045 steel billet cores. After machining the flywheel is zero balanced to ensure it is evenly weighted on all sides. Each steel flywheel is treated with a black oxide coating that adds a long lasting rust protection to the part. The flywheel is then assembled by a Clutch Master Craftsman, double checked for imperfections and tolerances, and is then ready to be paired with your OEM clutch kit or one of our FX100-FX500 single disc clutch kits or twin disc options. Will work with OEM clutch kit or aftermarket clutch built to OEM specifications. 8-bolt crank
