Kibblewhite Black Diamond Valves

Kibblewhite Black Diamond valves are CNC-machined from one-piece forgings of EV8 stainless steel, impregnated by a special German process to a depth of .002 in. with a surface buildup of .0002 in. This proprietary, multi-stage process reduces friction and provides superior resistance to wear and corrosion over traditional chrome and nickel electrolysis plating processes. These valves go through an oxiding and polishing process that creates an extremely smooth surface finish that's easy on valve guides, and there's nothing to flake off and get trapped between the valve and guide to cause seizure or wear! Kibblewhite Black Diamond valves are designed using Finite Element Analysis software, with profiles tested on Kibblewhite's computerized flow bench to provide excellent flow characteristics. These strong, reliable, and lightweight valves are your ticket to ultimate valvetrain performance!

CP Pistons CPK Piston Kits

CP Pistons CPK piston kits come complete with a piston, wrist pin, locks, rings, and gasket. The anti-detonation grooves, also known as contact reduction grooves, protect the top ring by disrupting detonation waves. These grooves also limit the piston/cylinder contact during high temperatures and rpm. The featured accumulator groove is a V-shape machined into the second ring to collect excess blowby between the top and second rings. The accumulator groove also collects residual gasses during combustion and alleviates top ring flutter, while increasing ring seal. Other features, such as double pin oilers, in conjunction with their dual fed reservoir, add twice the amount of oil from the cylinder wall to the wrist pin. CP wrist pins have fine grooves that are intrinsically engraved into the product surface at the time of machining. These grooves are transformed into micro-dimple indentations to act as oil reservoirs, and the oil that would normally drain away through the grooves on an untreated product still remains in the dimples. X-forgings minimize friction and reduce weight without compromising strength. CPK piston kits go above and beyond in both quality and dependability.
