Replacement nuts for Stud Kit, #80-82450, but can be used for general purpose (see diagram for detail)
KPMI® nuts are single point machined from high tensile strength Aircraft Alloy Steel. During the machining process close tolerances and smooth surface 昀椀nishes are
maintained. Two critical factors for achieving correct 昀椀t and torque. After machining, the nuts are heat treated to a speci昀椀c depth. This creates hard, wear resistant working
surfaces, while retaining a ductile core to prevent cracking under load. The premium black oxide treatment provides excellent corrosion resistance and appearance.

H. T. Steel Tappets
KPMI® shim in tappet systems locate the adjustment shim in the hardened steel of the tappet body, where it is impervious to wearing (ovalling) and kicking the
shim out. By designing the tappet and retainer together as a system, the shim counterbore depth in the tappet has been maximized. This allows for increased
insurance against losing the shim even in the event of valvetrain separation during severe operating conditions, over-revs, or extreme boost pressures. It may be
necessary to use KPMI® Shortened Valve Guides # 80-81320, to achieve higher than stock lift.
