Oil Pump Pressure Spring Medium PSI

The Oil Pump Pressure Spring Medium PSI from Barnes is a precision-engineered component designed for builders and mechanics who require reliable oil circulation in modified and street performance engines. This spring regulates the cracking pressure of your oil pump's relief valve, ensuring consistent oil delivery across varying RPM ranges and engine loads. Proper oil pump pressure control is fundamental to engine longevity and protection against bearing wear.

Constructed from high-grade spring steel, the Oil Pump Pressure Spring Medium PSI maintains its tension characteristics across temperature extremes and extended operating cycles. The medium PSI rating positions this spring as suitable for most street and mild performance applications—stiff enough to prevent excessive bypass at idle, yet compliant enough to allow full flow under high-demand scenarios. Its compact size ensures it integrates seamlessly into Barnes pump assemblies without adding complexity or weight to your engine bay.

Technicians and DIY builders choose the Oil Pump Pressure Spring Medium PSI when replacing worn or weak pump internals or upgrading to a higher-capacity oil pump. Installation requires basic mechanical skill and familiarity with pump disassembly; this component pairs directly with Barnes pump kits and compatible OEM pump housings. Verify compatibility with your specific application to ensure optimal performance.
