Description

So what is the New Callies Apex Series?! Well take a look at the picture
Callies knows that everyone doesn’t need or has the budget for the Magnum or Billet cranks. So Callies went to work to find a solution!
Apex is a crankshaft made on the same forgings Callies uses to make their Magnum Series crankshafts
Callies has the same supplier that makes Compstar Machine them.
Callies does all the finish sizing in house and fully inspect.

What does this get you?
First and foremost a known material with a good core or thru hardness.
The core hardness up to our known standards for strength and with that along comes a better nitriding process too.
This crankshaft will take 2500 hp at minimum
