Hi-Press Oil Pump Spring BBC (60-85 psi)

The Hi-Press Oil Pump Spring BBC (60-85 psi) from Canton is an essential upgrade for big-block Chevrolet engines that require reliable oil pressure control during high-RPM operation. This spring assembly replaces the stock pressure regulation component, ensuring consistent lubrication delivery for aggressive engine builds and forced induction setups.

Designed to maintain oil delivery within a range of 60–85 psi, this spring prevents under-lubrication at idle and excessive pressure spikes at redline. Its calibration works in conjunction with the oil pump's bypass valve, effectively controlling flow rate and system pressure as engine speed varies. This design protects critical bearing surfaces and reduces wear, making it a necessity for any serious BBC build.

BBC engine owners upgrading to high-volume or gear-driven oil pump systems will find this spring crucial for proper system tuning. Its compact and lightweight design fits standard BBC oil pump housings without modification, ensuring straightforward installation for both professional builders and experienced home mechanics.
