• H.T. Tool Steel Retainers
• Your Titanium Retainer Alternative

KPMI® performance valve spring kits are modeled using cam profile and simulation software. By utilizing Finite Element Analysis (FEA) software, it was possible to take advantage of the increased strength and wear resistance of a heat treated steel retainer, while reducing its mass to within grams of a comparable titanium retainer.
