Description:

This is the crank we use when going after BIG POWER. 

Callies Ultra billets are machined from Premium Grade (Para-Pure) Timken alloy steel.  From the raw materials, through the foundry to Callies' plant in Fostoria Ohio, these crankshafts are 100% MADE in USA. This high quality Timken steel alloy has been formulated to create a level of toughness that is unmatched in the crankshaft industry.  The fully counter-weighted design and Callies' heat treatment protocol further increase the torque these cranks can handle.

Each Ultra billet crankshaft is uniquely machined with 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 gives a crankshaft that is totally stress-riser free and incredibly aero efficient. When the Ultra-Shed and Aero-Shed processes are combined, the result is a crankshaft with the lowest coefficient of drag in the industry. 

The cranks we have in stock are a mix of stroke length (4.000" & 4.250") and main journal diameters (2.559 and 2.750").  Please call for details and specific availability,
