Who should use this kit?
Anyone who can afford it!
There are no drawbacks to less reciprocating mass in your engine, only gains. Such as being faster revving with better valve control, less parasitic drag, and higher RPM capabilities for engines running high duration 'big' cams. This is an ideal kit for roadracing or drag racing.

The set-up on this kit is critical and it must be installed by a qualified shop with a higher level of experience than average and the proper tools.



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 software, and draw on their 70+ years of design experience to create these systems. Their design, simulation, and manufacturing processes insure compatibility of the valve spring’s force and natural frequency with the cam profile, valvetrain 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 they use 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, allow them to supply you with the best valve springs in the world.
