  • Ultra Billet - Dirt / Oval

  • Ultra Dirt Billet cranks are application specific designed billet cranks made from Callies proprietary TimkenSteel 4330. Specifically designed for circle track applications where the absolute minimum reciprocating weight is demanded without sacrificing strength. Torsional fatigue is mitigated through strength enhancing pin arms. Counterweights are reduced in radial width to reduce weight but at the same time not sacrificing balance characteristics.
