HVHP oil pumps have a new gear tooth profile with fewer but larger teeth that provides an increased oil volume for both supply and return side of the pump. Supply side gears are 9% wider than stock. Return gears are 28% wider than stock to ensure that the additional volume of oil supplied to the engine is scavenged and returned to the oil tank, reducing the amount of oil in the crankcase breather. Standard style pumps have 92-99 style oil line hookups. Available as a kit or oil pump only. Oil pumps only include supply gears, return gears, drive shaft keys, drive shaft snap rings, check ball, check ball spring, pressure valve spring, cover screws with O-rings, miscellaneous hose fittings, plugs, screws, gaskets, mounting hardware and instructions. Made in the USA.
