Suitable for M-8 platforms from 2017 and up, this new multi-use dowel manufactured in California by KPMI has been designed to replace the OEM dowel in the heads, cylinders, crank case, and cam-support cover of M-8 engines.
Described as “incorporating OEM elements while increasing ease of installation through the overall shape of the part”, a radiused end is said to allow easy insertion into the cylinder or case, with a tapered end designed for “hassle-free location of the mating holes in the head or cam-support cover.”
Conveniently packaged in quantities of four, eight and 20 they are black oxide coated, corrosion resistant and offer improved tolerances over the OEM component.
Last year saw KPMI introduce a slew of product design updates for M-8s, including high performance replacement and high lift beehive spring kits. Wound from a blend of chrome silicon wire that is designed specifically for performance valvetrain, they allow the use of aggressive cam profiles, with lifts of up to .550” for performance builds.
KPMI’s heat-treated steel retainers provide excellent durability and life expectancy and weigh only 2 g more than their titanium equivalent, with titanium retainers also offered for performance applications that require the lightest possible high strength parts.
KPMI ‘Black Diamond’ intake and exhaust valves are said to offer combined weight savings of approximately 6.8 g over the OEM components, reducing wear and tear on the rest of the valvetrain and allowing the engine to rev higher. KPMI also offers ‘White Diamond’ Inconel exhaust valves for extreme duty applications with high exhaust gas temperatures.
Kibblewhite’s C630 nickel aluminum OEM replacement bronze guides extend the life of an engine build by providing greater wear resistance and heat dissipation with their manganese bronze and cast-iron guides offering greater ease of installation and sizing; a specially sized reamer is also available.
All KPMI intake guides have port geometries with reduced cross sections for increased air flow; their OEM replacement keepers and valve stem seals are kept in stock dimensions.
