Description

CALLIES Compstar – Duramax Crankshaft (2001-2016)

Callies Durastar crankshafts are designed to be substantially stronger than OEM shafts currently found in GM’s popular Duramax diesel. This improvement is the result of substantially stronger steel, considerably deeper nitride layer and unique machining features.

Durastar crankshafts are intended to be externally balanced with stock damper and flywheel configurations.
