DS Oil Pump Tri-Lobe 3-Stage RHS MP Mount

The DS Oil Pump Tri-Lobe 3-Stage RHS MP Mount by MOROSO is engineered for high-performance engine builders and professional mechanics who demand precision lubrication under extreme operating conditions. This tri-lobe design delivers superior oil flow compared to conventional gear-driven pumps, making it the go-to choice for race engines, forced-induction builds, and heavy-duty applications where engine reliability is non-negotiable. The right-hand (RHS) rotation configuration with MP (mechanical fuel pump) mount compatibility ensures seamless integration into modern engine platforms while maintaining optimal oil pressure delivery across all RPM ranges.

The three-stage tri-lobe rotor geometry maximizes volumetric efficiency, eliminating the dead zones present in two-lobe designs and substantially reducing cavitation noise and wear. MOROSO's precision manufacturing ensures tight tolerances that prevent slippage and maintain consistent displacement, critical for maintaining fuel pump operation and protecting against oil starvation during high-G cornering or aggressive acceleration. The MP mount bracket allows direct attachment to the engine block without adapter plates, streamlining installation while reducing vibration transfer to auxiliary systems. Weighing 8.71 lbs with a compact footprint (10.7 x 10.5 x 14.25 inches), this pump integrates efficiently into tight engine bays without sacrificing cooling airflow or component accessibility.

Professional engine builders, drag racers, and off-road enthusiasts benefit most from this tri-lobe configuration, particularly in applications requiring sustained high oil volume at elevated temperatures. The RHS rotation makes this pump ideal for engines with right-handed accessory drive systems, common in small-block and big-block platforms. Installation requires verification of crankshaft rotation direction and confirmation of available mounting pad clearance; consult your engine manual or builder specifications before ordering to ensure proper compatibility with your specific engine block configuration.
