BBC Hi-Pressure Oil Pump Spring - 50-70psi

The BBC Hi-Pressure Oil Pump Spring 50-70psi by CANTON is a precision engine component engineered for Big Block Chevy engines requiring elevated oil system pressure. This relief spring maintains consistent hydraulic pressure across demanding driving conditions, protecting critical engine components from over-pressurization while ensuring adequate lubrication delivery. Engine builders, performance enthusiasts, and restoration specialists rely on quality oil pump springs to prevent bearing wear and extend engine longevity in both street and competition applications.

Constructed from high-grade steel, this oil pump relief spring is calibrated to crack at 50–70 psi, allowing excess pressure to bypass the system before damage occurs to gaskets, seals, and bearing surfaces. The spring's compression rate and material composition directly influence oil flow regulation and system responsiveness; a properly matched spring prevents cold-start binding while protecting the pump during hot operation. CANTON's manufacturing tolerances ensure consistent performance across temperature ranges, critical for engines experiencing sustained high RPM or extreme ambient conditions.

This relief spring is essential for BBC engines with aftermarket oil pump upgrades, modified bearing clearances, or high-flow cooling systems where standard springs prove inadequate. Installation requires basic mechanical knowledge and is typically completed during routine oil pump service or engine rebuild. Verify pump housing compatibility and existing spring specifications before ordering to ensure correct pressure rating for your specific engine configuration.
