Description

KPMI takes a scientific "System" approach when designing their Valve spring kits. Each component is designed to work with the others as part of the complete system. KPMI's engineers use their proprietary design and simulation softwares, and draw on their 70+ years of design experience to create these systems. Kibblewhite's design, simulation, and manufacturing processes insure compatibility of the valve spring's force and natural frequency with the cam profile, valve train mass, system harmonics, and the engine RPM. Their spring manufacturing partners are U.S based companies that are ISO certified. The Super-Clean Chrome Silicon valve spring wire used is traceable back to Kobe Japan where some of the best spring wire in the world is manufactured. Combining their design and simulation protocols with this premium quality valve spring wire, and manufacturing processes including, heat treatment, stress relief, and shot peening, allows Kibblewhite to supply you with the best valve springs in the world.
