Part Number: CAL-AP&31T-DS
Callies Crankshafts are at the top of the industry for quality of finish and reliability. Their precise, no compromise production efforts deliver dimensional accuracy that is second to none. Concentricity and surface finish are the two most desirable features in a high performance crankshaft journal. Each journal must be perfectly concentric to its specified center-line, and journal surface lobing (microscopic peaks and valleys in the journal surface) must be limited to no more than .00006″ to further enhance oil film integrity at high engine speeds.
Every crankshaft is 100 percent inspected for critical dimensions, and the manufacturing equipment is constantly monitored for tolerance drift and tool degradation. At Callies, quality and durability really are a driving force behind their products.
Callies can balance your DragonSlayer up to an 1820 bob weight at a special money saving LS1 price. Callies LS1 crankshafts are machined from premium 4340 forgings. Each Callies LS1 features PERMA-TOUGH heat treating for added strength and serviceability.
DragonSlayer LS1 crankshafts are sold with gun drilled mains and Angalite drilled rod journals.
Callies products, due to their intended use, are sold without warranty.
