1200 Series Valve Spring Kit

The PAC 1200 Series valve spring kit is engineered for demanding Ford Modular engine applications, offering a high-performance solution for both OEM engine replacements and upgraded builds. Each set includes 16 ovate beehive-style springs that utilize advanced metallurgy to withstand the extreme stresses of racing and high-RPM operation. These beehive springs are designed with a spring rate of 324 lb/in, a coil bind height of 1.040 inches, and an outer diameter of 1.105 inches. The specialized ovate wire geometry helps reduce mass and improve harmonic stability, which is essential for maintaining consistent valve train operation at high speeds. As a manufacturer with extensive testing capabilities, the company utilizes a fully accredited metallurgy lab for rigorous quality control, including fatigue and functionality testing in their dynamics laboratory. Buyers should note that this product may contain chemicals known to the state of California to cause cancer and reproductive harm. Ensure the spring specifications match your current camshaft profile and engine build requirements prior to installation.
