KIBBLEWHITE - 20-4170 - Exhaust Valve - Evolution
Description
Kibblewhite's Evolution Exhaust Valve is a one-piece stainless-steel valve that boasts impressive features. Through a special nitrided process, these valves are impregnated with a .002" depth and .0002" surface buildup, resulting in improved wear properties and reduced friction. Not only do they resist corrosion, but they also outperform hard chromium and electrolysis nickel-plating. These lightweight valves have profiles that ensure excellent flow characteristics. They are compatible with both leaded and unleaded fuels and can be used in cast iron- and bronze-type guides with close tolerances, allowing for maximum oil control and heat dissipation. Proudly made in the U.S.A., these Evolution Exhaust Valves are perfect for street riders seeking high-quality performance. The valve itself has a head diameter of 1.615" and a stem diameter of 0.3096". With a tulip angle of 29? and a length of 4.525", the Kibblewhite Evolution Exhaust Valve is a top-notch choice for any exhaust application.
