HSE SR20DET S13 Oil Pump Gear
The HSE SR20DET S13 Oil Pump Gears are a proven upgrade for the Nissan S13 SR20, designed to eliminate one of the common weaknesses of the factory oil pump. The OEM gears are manufactured from sintered metal and can be prone to failure, particularly in high-RPM and high-power applications.
Precision machined from high-strength 4340 billet steel, HSE gears are engineered for superior strength and durability. The N1-spec wave profile is designed to improve oil flow, while the isotropic polishing process produces an exceptionally smooth surface to reduce friction, vibration and stress concentrations.
These gears are a direct replacement for the OEM S13 SR20 oil pump gears, making them an ideal upgrade for performance engines, track cars and high-horsepower builds. The S13 SR20 version features an approximately 81mm outside diameter and 9.5mm outer gear thickness.
