Callies Magnum LS Crankshaft

Callies Magnum LS Crankshaft

$1,993.00

We here at Borowski Race Engines, Inc are big fans of Callies cranks and rods for a lot of reasons.  Performance is always part of the equation but durability is right up there. As we see it, price is less important than performance and durability since if it either doesn't work or wrecks your engine, it was a bad deal.  Low cost Chinese materials or parts may be okay in low performance engines coming from the OEMs but they have no business in high performance builds such as whatever you are thinking about right now.

Quality design, materials and machining is what delivers the performance and survivability.  We have gone the extra mile to select only those key suppliers who pass our extreme vetting process.  For Callies, that included a factory tour to inspect their manufacturing and QC procedures.  We confirmed that Callies Magnum cranks use Timken steel alloys cast and forged in the USA with all machining and finishing done at their plant in Fostoria Ohio.  Here is a video showing their final step which includes dimensional checks and polishing:
