KAD flywheel keyway washer is manufactured from high quality EN24 steel and is a must for any performance engine. For pre-verto race type flywheels only.

Can you really trust a standard soft, worn keyway washer to cope with high rpm and power?

Failure of standard washer can be catastophic to engines. The flywheel will weld itself to the the crank, ruining the crank, flywheel and causing harsh vibrations throughout the engine. Correct quality components and fitment will prevent this.
