KPMI® engineers design our tappets using advanced finite element analysis (FEA) software. This software allows our engineers to lighten the tappets without sacrificing strength, which creates the strongest and lightest tappets possible. The tappets are then machined from billet aircraft quality steel. After machining the tappets undergo a proprietary heat treatment process that creates a hard surface and a non-brittle core. These materials and processes maximize toughness and wear resistance. To finish the tappets they are OD ground and then the contact area is lapped and polished to create a very flat and smooth surface , the cam to run against. 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.
