Oil Pump Pressure Spring High PSI

The Oil Pump Pressure Spring High PSI by Barnes (MPN: BYP-019) is a precision internal engine component designed to maintain optimal oil system pressure under demanding operating conditions. This high-pressure spring is essential for engine builders, performance mechanics, and enthusiasts who require reliable oil circulation in modified or high-revving powerplants.

Oil pump pressure springs regulate the relief valve within your pump assembly, controlling when excess oil bypasses the system to prevent overpressure conditions that can damage seals, gaskets, and bearing surfaces. A high PSI spring maintains elevated baseline pressure, which is critical for thick-film lubrication on heavily loaded crankshaft and camshaft bearings common in turbocharged, supercharged, or naturally aspirated performance builds.

This spring is ideal for applications where consistent oil pressure is necessary, particularly in performance engines. Mechanics upgrading engine internals or diagnosing chronic low oil pressure issues will find this product beneficial for ensuring proper lubrication in their systems.
