Ext Oil Pump 2-Stage Tri-Lobe LHS FP Drive

The Ext Oil Pump 2-Stage Tri-Lobe LHS FP Drive by MOROSO is a high-performance external oil pump designed for serious engine builders and performance enthusiasts who require superior lubrication under extreme conditions. This left-hand suction (LHS) unit is essential for applications that need independent oil system control, making it ideal for drag racing, street performance builds, and heavily modified engines where factory oiling systems may not suffice.

The tri-lobe design of this pump ensures consistent pressure and volume, particularly when stock systems fall short. It features a 2-stage rotor design that optimizes oil flow across the entire RPM range of your engine. This architecture guarantees maximum flow at low RPM for quick warm-up and protection of bearings, transitioning seamlessly to higher displacement at elevated RPMs when volumetric demand peaks.

Ideal for racers and engine rebuilders, this MOROSO pump is particularly beneficial for those running superchargers, turbos, or naturally aspirated engines. Its FP drive configuration provides direct, positive displacement without slip, ensuring absolute control over oil volume—critical for tight bearing clearances or high-lift cams that require aggressive lubrication.
