What is the z-Start Pro made from?
The z-Start Pro Clutch is made from the highest quality billet 6061-T6 aluminum and billet 4140 steel, precision CNC machined to tolerances of .001″ (that’s one one-thousandth of an inch). The center clutch and pressure plate are hard anodized for additional durability. The top plate sent through a final nitrating process to increase the surface that the 7/16″ steel balls will run against.
