Callies Ultra Billet Crankshafts
Callies Ultra billet crankshafts are intended for use in cutting edge applications where durability and innovation are a must. They are machined from premium grade (Para-Pure) Timken alloy steel formulated to create a level of toughness that is unmatched in the crankshaft industry.
Each Ultra billet crankshaft is uniquely machined with Callies' Ultra-Shed counterweight profiles. The Ultra-Shed leading edge profile gently moves oil away from the oncoming counterweight while the directional trailing edge directs oil away from the oncoming rod journal. Callies' Aero-Shed super finish will give you a crankshaft that is totally stress-riser free and incredibly aero efficient. When these processes are combined, the result is a crankshaft with the lowest coefficient of drag in the industry.
Callies has developed a wide range of part numbers for a variety of popular engines. Choose the Ultra billet crankshaft created for your engine.
