Product Description
Cummins 3925009 OEM Oil Pressure Regulator Compression Spring for 5.9L & 6.7L Cummins Engines
The Cummins 3925009 OEM Oil Pressure Regulator Compression Spring is a genuine Cummins replacement component designed to maintain proper oil pressure regulation within the lubrication system of 5.9L and 6.7L Cummins diesel engines. This spring works with the oil pressure regulator assembly to help control oil pressure, ensuring consistent lubrication and long-term engine protection.
Over time, oil pressure regulator springs can weaken due to heat cycles, mileage, and engine wear. Replacing a worn regulator spring with a genuine Cummins 3925009 helps restore proper oil pressure control and supports reliable engine operation. This OEM replacement is commonly used during engine rebuilds, oil pump service, and preventative maintenance on Dodge Ram Cummins-powered trucks.
