Callies Engine Crankshaft

Callies Engine Crankshafts: Where Precision Meets Performance

When serious engine builders and racers need a crankshaft they can stake their program on, Callies Performance Products is the name that consistently shows up in winners' circles. Founded in 1989 and headquartered in Fostoria, Ohio, Callies has spent over three decades engineering and manufacturing some of the most dimensionally precise, metallurgically superior engine crankshafts available in the performance aftermarket. Their philosophy is simple: no compromises on concentricity, surface finish, or material quality — the two most critical factors in a high-performance crankshaft journal.

A Tiered Lineup Built for Every Build

Callies structures its crankshaft catalog around clearly defined product tiers, so builders can match the right crank to their power goals and budget without sacrificing quality at any level.

• Compstar Crankshafts — Introduced as an accessible entry point into Callies-grade quality, Compstar cranks are forged using Callies-owned dies from 4340 steel, semi-finished offshore, then shipped to Fostoria where American craftsmen complete the final sizing, polishing, and quality control. Every Compstar crank undergoes 100% Mag Particle inspection and in-house metallurgical lab verification before leaving the facility.
• Magnum Crankshafts — Manufactured from ultra-pure AISI 4340 steel and subjected to multiple heat treatments including Callies' proven Ultra-Case nitride process, the Magnum line delivers superior bearing life and enhanced material distribution across rod journal arms. The Magnum is also available for the Ford 7.3L "Godzilla" platform — a fully counterweighted, US-made forged crank capable of handling everything from street rods to ultra-high-output drag racing.
• Ultra Billet (UB) Crankshafts — Machined from Callies-sourced 4330 bar stock from TimkenSteel in Ohio, the Ultra Billet line incorporates design lessons drawn directly from Callies' Top Fuel crankshaft program. Reinforced pin arms, increased material in critical strength regions, and super-finished journals make the Ultra UB ideal for the most demanding high-output applications.

Broad Platform Coverage, Exacting Standards

Callies crankshafts span an impressive range of platforms, including GM LS/LT, Big Block and Small Block Chevy, Big Block Mopar, Gen III Hemi, Ford 460, Ford Coyote, Ford Godzilla 7.3L, Mitsubishi 4G63, and Subaru applications. The Compstar line for the Ford Coyote, for instance, features large strength-enhancing journal radii and comes nitrited as standard — and is available in stock stroke or stroker configurations up to 3.900 inches. For Mopar builders, Callies' decades of platform experience translate into cranks engineered specifically for both Wedge and Hemi architectures.

What sets Callies apart is the integration of CNC machining technology with rigorous in-house quality controls. Every crank is checked for runout, oil hole placement, and bolt hole accuracy before it is approved for release — a level of thoroughness that gives professional engine builders the confidence to spec Callies into builds where failure simply isn't an option.
