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.

Keyed Shear Proof timing gear fit
Drilled rod journals for reduced inertia and ease of balance
Stock 3.898” stroke with OEM journal diameters and width
Machined from 4340, through hardened steel
Dual keyed damper fit
Conservatively rated for 800hp @ 800 ft / lb torque
Will accept OEM post and flange bolts
Machined to accept OEM flywheels / flexplates
All journals are polished to a 6Ra or finer finish
Main bearing oil holes are machined with lead-ins for enhanced cold start oil flow to rod journals
GM timing gears are available
