Valve Springs

Peterson Spring has been an innovator within the racing industry for almost a century. As a major supplier to premier OEM, tier 1, and aftermarket camshaft manufacturers, we design and build state of the art valve springs for all forms of applications.

By applying advanced manufacturing techniques such as gas nitriding, surface enhancement and precisely controlled heat-treatment stages, Peterson 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.  Only the highest quality, super-clean, high strength alloy is used in PACALOY® Valve Springs, which have become the standard across the professional racing industry.

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.
