Scat Crank Anatomy

SHAPED AND STYLED JUST FOR YOU!!

      



In the world of crankshafts, the quality and depth of our cast and forged crankshafts is second to none.

But SCAT also can make to your specs a custom Billet or Forged crankshaft, shaped and style the way YOU want it. Our billet cranks continue to be a favorite.

A billet crank is the strongest, because unlike the forging which has uneven grain structure and stress (a result of the forging process), the billet has a uniform and non - stress grain structure.

A custom forged crank has all of the features of a billet but the material is made by taking a piece of steel and forcing it into roughly the correct shape for a crankshaft. These are durable high quality cranks, not to the extent of a billet, but easier on the check book.

Standard Features in every Forged & Billet PRO STOCK crank:
  • Straight Shot and Chamfered Oil Holes
    • Radius on all Journals (typically .125”)
    • Lightening Holes in #1 & #4 Rod Throws
    • Stress Relieved & Shot Peened
