Considered the world’s premier valve spring manufacturer Peterson Spring has been an innovator within the industry for almost a century. As a major supplier to OEM, Tier 1, and aftermarket camshaft manufacturers, we design and build state-of-the art valve springs for all forms of applications as well as springs in fuel injectors, latch mechanisms for valvetrain components, springs in torque converters, and clutch assemblies.
By applying advanced manufacturing techniques such as gas nitriding, surface enhancement and precisely controlled heat-treatment stages, Peterson’s springs minimize load loss while in service. An optimum combination of mechanical properties, stress profiles and surface conditions are used to generate the maximum possible life and speed capability. PACALOY® Valve Springs have become the standard in professional racing with their high strength, super clean alloy, and highest quality.
Technological and Engineering Capabilities
Two advanced laboratories are dedicated to ensuring the quality performance of our engine-powertrain springs. In the metallurgical laboratory, our scientific and technical staff can process samples for raw material qualification and validation. We use a full range of analytical resources to examine fundamental material properties:
In the dynamics laboratory our engineers employ a full range of testing resources to examine production or prototype springs in conditions that closely approximate actual use:
Our engineers are fully experienced in product design, spring design analysis, dynamic simulation, and the application of advanced technology to produce innovation. We use a variety of software for spring design, modeling and assembly, and FEA to optimize performance. We use 2D dynamic motion software, 3D dynamic simulation modeling software (ADAMS), solid modeling (NX), 2D drawing software (NX, ProE, ACAD), and spring design tools (IST, SMI, PAC). The latest improvements are on: advanced high tensile materials, nitriding and piece hardening, ovate and multi-arc wire sections, Beehive spring configuration, and advanced surface-finishing processes.
Whether you need valve springs for a motorcycle with an 18,000 RPM engine or a low-horsepower engine, Peterson Spring has the technology and the know-how to match you with the proper valve spring to meet your needs.
PAC Racing Springs’ value- engineered products provide unsurpassed performance for NASCAR, F1, Drag, Rally, Sprint Racing, and everyday street performance in all forms of motorsports. Peterson Spring manufactures a range of high stress, low ppm, zero defect, asymmetrical, ultra clean circle track, RPM series, drag race, beehive, LS engine, street performance, and motorcycle or ATV valve springs.
