PAC Racing’s 1300 Series Dual Valve Springs were designed to have the highest endurance and the latest advancements in valve spring processing.
They are constructed of our signature PACaloy super clean wire and are heat-treated in-house for precise spring rates and improved strength. A multi-peen process is also employed to extend service life. The damper uses the friction between it and the valve spring to minimize spring surge.
Unique to the 1300 Series is ID/OD chamfer finishing, a run through the polisher, and a Nano-Peen™ proprietary surface treatment for improved operating cycles.
