Made with roll-formed threads for a precise, tight fit, and with an anti-drainback valve to keep oil in the filter after engine shutdown, they are perfect for any race application.

Moroso Spur Gear Oil Pump Springs

Moroso offers replacement bypass relief springs for various spur gear oil pumps, used to regulate oil pressure by controlling the flow of oil back into the pump's inlet. The 3-spring kits are designed for use with Nos. 22163, 22164, and other billet Moroso spur gear BBC oil pumps, as well as Tri-Lobe Series external/dry sump pumps. Kits contain a blue (50-60 psi), purple (60-70 psi), and brown (70-80 psi) spring to help tune the engine's oil pressure to a desired level. These springs are a critical component of an oil pump's pressure relief system. When oil pressure exceeds a certain threshold, the spring compresses, allowing excess oil to bypass the main circulation and return to the pump's suction side, which prevents excessive pressure and potential engine damage.
