Callies Crankshafts
Magnum XL Series
(Chevy, LS1)
Callies establishes a new standard in Lightweight Cranks.
Magnum XL lightening profiles result in crankshafts having
extremely high strength to weight ratios. Material is carefully
removed from non-stressed areas of each shaft to eliminate parasitic
weight. The Callies Magnum XL profile is effective at minimizing
windage within the crankcase atmosphere. Oil control is improved by
not relying on counterweight undercutting to eliminate weight.
All Magnum XL Cranks feature the Callies Perma-Tough heat treatment.
This process is a true heat treatment and results in a hardened heat
pattern that offers years of service and re-grindability. Each main
and rod journal is drilled for weight reduction and throttle response
improvement. |
