549 50-316278 S&S® Billet aluminum oil pumps for Big Twins® CNC machined to maintain close tolerances and strict quality control, these billet oil pumps all feature the same oiling pattern as 1981-up engines. This result in split oil path that applies more pressure to the top end for longer component life. Each pump features multiple oil ports for a variety of plumbing options. Kits include: billet oil pump, supply and return gears, drive shaft with keys and snap rings, check ball and spring, pressure relief valve and spring, check ball and relief valve cover screws with O-rings, gaskets, fittings, and hardware.

The gear tooth profile and the the extra gear width of the HVHP oil pump work together to maintain higher oil pressure, and to scavenge additional oil from the crankcase.

The SSW+ engines feature piston cooling jets that spray oil on the underside of the pistons. In order to supply enough oil for the cooling jets in addition to the oil requirements of the rest of the engine, a new pump was needed. Although the HVHP oil pumps are very similar in appearance to the standard S&S® billet pumps, there are several important differences. S&S® High Volume High Pressure oil pumps are recommended for any engine with 91-99 style crankcases. Special design features: • A tooth profile with fewer, but larger teeth, provides increased oil volume for both supply and return sides of the pump. • Supply gears are 9% wider than stock or standard S&S® oil pumps to give the HVHP pump even more oil capacity. • Return gears are 28% wider than stock or standard S&S® pumps to insure that the additional volume of oil supplied to the engine is scavenged and returned to the oil tank, preventing oil carry over from the crankcase breather. • In spite of wider supply and return gears, the HVHP pump is no thicker than stock and uses the stock oil pump driveshaft. • The HVHP oil pump is available for 84-91 and 92-99 style crankcases. Although the 84-91 version will fit on late Shovel cases. We do not recomend the HVHP for this application as it may over oil the top end. • S&S® HVHP oil pump covers for 92-99 are available in two versions. The universal cover has a number of oil feed and return options allowing maximum flexibility for customized installations. The standard style covers have feed and return holes in the stock 92-99 locations. This works well for installations in stock 92-99 chassis. • S&S® HVHP oil pumps for 84-91 are available with the universal cover only.
