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

The BBC Hi-Pressure Oil Pump Spring - 50-70psi by CANTON is a precision engine component designed for Big Block Chevy engines that require elevated oil system pressure. This relief spring is essential for maintaining consistent hydraulic pressure, protecting critical engine components from over-pressurization while ensuring adequate lubrication delivery during demanding driving conditions.

Constructed from high-grade steel, this oil pump relief spring is designed to operate within a pressure range of 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, preventing cold-start binding and protecting the pump during hot operation.

Engine builders, performance enthusiasts, and restoration specialists benefit from this spring, especially in applications with aftermarket oil pump upgrades, modified bearing clearances, or high-flow cooling systems. Installation requires basic mechanical knowledge and is typically completed during routine oil pump service or engine rebuilds.
