1987 1988 1989 1990 OIL PUMP RELIEF VALVE SPRING

Part Number: 98-385

OIL PUMP RELIEF VALVE SPRING - Part Number 98-385
H-D engines operate at extremely low oil pressure, both while at idle and during upper RPM operation. This premium quality, steel alloy, heat set oil pump pressure relief spring actually increases engine oil pressure by 2 -3 PSI, and doesn't interfere with critical bearing lubrication needs. This added oil pressure is necessary when using aftermarket cams and valve train components and is highly desirable for extended engine life.
