Callies Crankshafts
Ultra Billet Crankshafts
Callies Ultra billets are machined from Premium Grade ( Para-Pure) Timken alloy steal. This high quality
specialty steel has been formulated to create a level of toughness that is unmatched in the crankshaft industry.
Callies has developed a wide range of part numbers for a variety of popular engines. Any main journal, rod
journal, post configuration, stroke or other specialized characteristic that you may require can be provided.
Callies Ultra Billet crankshafts are truly custom made to match your project.
We have designs in place for the following:
Conventional Small Block Chevy (Produced from Timken 4330VM)
4.500 Spread bore Small Block Chevy (Produced from Timken 4330VM)
LSx with any post or reluctor wheel (Produced from Timken 4330VM)
Conventional Big Block Chevy 4.840 Spread Bore (Produced from EN30B)
5.000 Spread bore Big Block Chevy (Produced from EN30B)
5.300 Spread bore Big Block Chevy (Produced from EN30B)
MAGNUM XL
Callies has once again established a new standard for lightweight crankshafts. 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 crankshafts feature the Callies Ultra-Case nitride treatment. This heat treatment method produces a deep case that enhances strength while creating an extremely hard load bearing wear surface. The Ultra-Case process generates a layer of hardened steel deep enough to maintain its integrity even after a -.010 regrind.
Each main and rod journal is drilled for weight reduction and throttle response improvement.
Magnum XL Lightening Profiles
Our unique Magnum XL lightening profiles were developed to optimize material distribution for enhanced strength, superior bearing load reduction, and consistent balance.
Sprint Car Specific 4 Bolt Flange
The first crankshaft designed for direct drive sprint cars has won races and acclaim since its release. These unique shafts benefit from extensive weight removal in the post and flange areas. The post is tapped to accommodate a standard Callies stud.
Big Block Post
Big Block or Small Block diameters can be ordered for the damper and gear fit area on your Small Block Chevy crank. Dual key-ways can be specified if needed.
LS1 Tone Wheel
GM LS Series Magnum XL cranks are available with tone wheels for Gen III and Gen IV through 2005, or the billet version for late model LS2 – LS7 engines.
Balancing included
Magnum XL crankshafts are shipped fully balanced to your exact assembly weight without drilling. These shafts are available in many custom configurations. Your order will be processed specifically to meet your needs
MAGNUM
Innovative New Design
Your request for a lightweight yet durable crankshaft for the powerful big block Chevy engine has been answered. Callies’ design team has optimized material distribution throughout this crankshaft to produce a component that is strong yet easy to balance.
Many BBC crankshafts are counterweighted to offset simple balance forces detected at main bearings 1 and 5 by today’s precision balancers. Callies Magnum Mass Correct counterweights have been strategically placed to reduce imbalance forces over the entire length of the shaft. The result is a crankshaft that exhibits superior bearing life and minimal wear.
Material distribution over the rod journal arms and critical strength generating regions of Magnum BBC crankshafts has been enhanced as well. These slight design changes improve the strength to weight ratio ensuring each Magnum crank will have an extended fatigue-resistant life.
Our Dual Arc leading edges create a unique counterweight that is beneficial in the reduction of disruptive crankcase windage. This profile characteristic is of greatest value in high RPM, large displacement engines.
A typical 4.500 stroke BBC shaft will have a finished weight of 69 lbs. All rod journals are drilled with generously radiused lightening holes. Each counterweight features Callies’ (Dual Arc) windage reducing leading edge.
DRAGONSLAYER
DragonSlayer crankshafts are made in the U.S.A. for American Racers. With an expanded line of part numbers, the DragonSlayer is rapidly setting the standard by which other Sportsman crankshafts are measured.
These shafts are machined to the tolerances demanded by today’s high performance engine builder. Roundness and taper are held to less than .0003 on all rod and main journal diameters. Our final polishing procedures produce excellent load carrying surfaces that ensure extended bearing life and trouble free operation.
Each DragonSlayer features the Callies Ultra-Case nitride treatment. This heat treatment method produces a deep case that enhances strength while creating an extremely hard load bearing wear surface. The Ultra-Case process generates a layer of hardened steel deep enough to maintain its integrity even after a -.010 regrind.
Callies heat treat expertise combined with our high purity premium 4340 forging produce strength of unparalleled value. All DragonSlayers are produced with standard Chevy rod journal diameters and widths for SBC, BBC, LS1, and Mopar applications.
COMPSTAR
Compstar Performance Crankshafts are designed by our engineers, and forged on proprietary dies, made to our specifications. They are rough machined from certified AISI 4340 forgings to our tolerances, then finish machined in our facility.
Our in house solid modeling abilities provide a great advantage in product development. We’re able to precisely locate material where it will yield the greatest advantage in terms of both strength to weight, and balance ability
Beginning with properly placed counterweights that not only improve balance but reduce bearing loads, every aspect of these highly stressed components has been analyzed. Our forgings are rough machined in a process that includes double stress relief operations that make these crankshafts very dimensionally stable.
Hardened with a deep nitride, Compstar cranks are ideal for all types of abusive racing environments. All rod journals are drilled and counterweights are profiled for piston clearance. With our consistent grind and polish, along with our precise stroke and index, you will see why we say these crankshafts are Compstar Correct.
Compstar crankshafts are available in a variety of Small Block Chevy, Big Block Chevy, Late Model Hemi, and LS1 configurations.
