Callies Performance Products: American-Made Precision for High-Performance Engines

Callies Performance Products has been a cornerstone of the high-performance engine world since 1989. Founded in Fostoria, Ohio, the company grew from roots in tool-and-die and OEM crankshaft manufacturing into one of the most respected names in motorsports-grade engine components. Today, Callies serves professional engine builders, drag racers, circle track competitors, and serious street enthusiasts who refuse to compromise on rotating assembly quality.

What sets Callies apart is a relentless commitment to precision. The company leverages advanced computer-aided solid modeling and state-of-the-art CNC machining centers to hold tolerances that most manufacturers can only aspire to. Every component that leaves the Fostoria facility is subject to rigorous dimensional inspection — a "no compromise" philosophy that has earned Callies products a regular presence in winners' circles across the country.

The Rotating Assembly: Where Callies Excels

At the core of the Callies lineup are their legendary engine crankshafts. Offered in multiple series — including the Compstar, Magnum, Magnum XL, and Ultra Billet lines — Callies cranks are forged from premium SAE 4340 steel and machined to exacting standards for concentricity and surface finish. Innovative design features such as center counterweighting help reduce harmonic vibrations, directly translating to more power and longer engine life.

Equally critical to a healthy rotating assembly are Callies' engine connecting rods, available in both H-beam and I-beam configurations under the Ultra and Compstar product families. These rods are forged from 4340 or 4330 steel and engineered to handle the enormous tensile loads generated in high-boost, nitrous, and naturally aspirated race applications. For builders who prefer to purchase a complete set in one go, Callies also offers engine connecting rod sets that ensure matched tolerances across all cylinders — a critical advantage when building for consistency and balance.

The hardware that holds a connecting rod together is just as important as the rod itself. Callies' engine connecting rod bolts are engineered to complement their rod lineup, with options compatible with ARP 2000 fasteners and Callies' own WSB (Wedge-Shank Bolt) designs, providing the clamping force and stretch characteristics required in high-RPM race environments.

Complete Bottom-End Solutions

Through its sister company, Energy Manufacturing, Callies extends its reach into engine blocks — machining billet aluminum, cast aluminum, and cast-iron blocks that serve as the foundation for complete, ground-up engine builds. This integration means builders can source the entire bottom end — block, crank, and rods — with components designed to work together from the outset.

Trusted by competitors in the NHRA, PDRA, tractor pulls, drift events, and sprint car racing, Callies Performance Products brings decades of American manufacturing expertise to every part they produce. Whether you're building a weekend bracket racer or a four-digit-horsepower Pro Modified engine, Callies delivers the precision and durability that serious performance demands.
