DS Oil Pump Tri-Lobe 5-Stage LHS FP Drive

The DS Oil Pump Tri-Lobe 5-Stage LHS FP Drive by MOROSO is a high-performance engine oil pump designed for serious engine builders and performance mechanics who demand precision lubrication under extreme conditions. This left-hand shaft (LHS) pump is engineered for applications requiring front pad (FP) drive configurations, making it ideal for custom engine builds, racing platforms, and heavily modified street machines. Whether you're assembling a stroker motor, upgrading a vintage classic, or building a competition engine, this pump delivers the reliable oil delivery your high-revving powerplant requires.

The tri-lobe rotor design combined with five-stage internal geometry maximizes volumetric efficiency across the RPM band, ensuring consistent oil pressure delivery even at sustained high engine speeds. MOROSO's precision engineering in this pump produces smoother flow characteristics and reduced noise compared to traditional two-lobe designs, while the five-stage configuration allows for aggressive cam profiles and high-lift valve trains that demand superior lubrication. The left-hand drive orientation and front pad drive interface make this pump compatible with specific engine block configurations and drive systems commonly found in big-block and small-block modified applications where space and drive geometry are critical constraints.

This pump is best suited for engine builders working with aftermarket blocks, custom crate motors, and racing engines where OEM pump limitations become problematic. Installation requires proper matching with compatible engine blocks and front drive systems—verify your engine's lubrication requirements and drive configuration before purchase. Weighing 11.8 lbs and featuring compact dimensions suitable for tight engine bay installations, the DS Oil Pump Tri-Lobe 5-Stage LHS FP Drive integrates seamlessly into custom build strategies where reliability and performance cannot be compromised.
