S&S High Volume High Pressure Oil Pumps
Feature a new tooth profile with fewer but larger teeth that provide greater oil volume for both supply and return sides of the pump.
Supply gear is 9% wider than stock type oil pumps to give the HVHP pump more oil capacity.
Return gears are 28% wider than stock type pumps to insure that the additional volume of oil supplied to the engine is scavenged
and returned to the oil tank. In spite of wider supply and return gears the HVHP pump is no thicker than stock type pump and uses
the stock type oil pump drive shaft.
The standard style cover has feed and return holes in stock 1992-99 locations. Universal cover has a number of oil feed and
return options allowing maximum flexibility for customized installations.
Both types are available as oil pump assembly only or as a complete pump kit that includes pump, drive gear, pinion gear,
breather gear and shim kit.
