KPMI® engineers design our tappets using advanced finite element stress analysis software. This software allows our engineers to lighten the tappets without sacrificing strength so we can create the strongest lightest tappets possible. These tappets are machined from aircraft quality solid steel bar stock. They undergo a proprietary heat treatment process that creates a hard surface and a non-brittle core maximizing toughness and wear resistance. KPMI® tappets are run in high performance automotive and motorcycle racing applications including Motocross Flat Track Racing Road Racing Drag Racing and Land Speed Racing.
