Flywheel Step Specs - All Makes
The flywheel "step" specification is a very important factor for smooth and proper operation of any clutch.

When having your existing flywheel machined please keep in mind there are normally 2 types of machines used. A flywheel "cutting tip" or "lathe" type, and a flywheel "grinder" type. A flywheel "grinder" type usually removes far less material resulting in many more years of use out of your existing flywheel. Many machine shops, however, do not have a flywheel "grinder" type due to the extra cost. ("note" Always make sure a recess, or a sharp corner, is cut where your pressure plate mounts so that it is not held out slightly)

We have a complete selection of New Flywheels and New or Remanufactured Clutches at a fraction of OEM cost that are ready to install.

The following specifications should be double-checked carefully against manufacturer flywheel specs and pressure plate specs. Many manufacturers have several clutch configurations for each model. When in doubt feel free to contact us or call.
