Description

The Callies Duramag billet crankshaft is designed to be the last crank you ever need for your LB7 thru LML Duramax engine. These cranks are fully machined from domestically-sourced 4330 steel in our Ohio plant. Intended for the most extreme applications, some features of these shafts include large fillet radii across all journals, a nitrided surface, narrowed rod journals (2.154”), and straight shot oil holes. Additionally, these billet cranks are intended for an internal balance, resulting in reduced harmonics under high loads.
