Oil Pump Hi Press. Sprin

The Oil Pump Hi Press. Spring from MOROSO is a high-pressure relief spring engineered for Ford Cleveland and modified engine applications. This component is essential for engine builders and performance enthusiasts who demand precise oil pressure regulation under demanding operating conditions. Relief springs are critical to engine longevity, protecting internal components from excessive pressure spikes that can compromise gasket integrity and bearing clearances.

Set at a nominal 100 psi relief threshold, this high-pressure spring is manufactured from durable steel to withstand repeated compression cycles without fatigue or loss of preload. The spring maintains precise pressure control across varying engine speeds and load conditions, preventing oil starvation while avoiding unnecessary bypass flow. Its compact design—measuring 5.4 x 0.8 x 7.15 inches and weighing just 0.08 lbs—fits seamlessly into OEM and custom oil pump assemblies without modification. The material composition and engineering ensure consistent performance over extended service intervals, making it a reliable choice for street and competition use.

This relief spring is ideal for Ford Cleveland engine restorations, stroker builds, and high-output modified applications where standard pressure springs prove inadequate. Installation is straightforward—simply replace the original spring during oil pump service or assembly. Technicians and engine builders value MOROSO components for their precision fit and reliability, and this spring delivers the pressure stability needed to protect expensive engine internals. Compatibility is confirmed for Ford Cleveland platforms and derivatives; verification against specific engine specifications is recommended before purchase.
