DS Oil Pump Tri-Lobe 5-Stage RHS MP Mount

The DS Oil Pump Tri-Lobe 5-Stage RHS MP Mount by Moroso is engineered for serious performance engine builds where oil delivery efficiency and durability are non-negotiable. This tri-lobe design pump is purpose-built for high-output engines requiring consistent pressure and flow under extreme operating conditions. Whether you're building a competition engine, stroker, or forced-induction platform, this pump delivers the volume and reliability that separates a weekend warrior build from a track-proven powerhouse.

The five-stage internal geometry maximizes oil delivery throughout the RPM range while the tri-lobe rotor configuration provides superior flow consistency compared to conventional gear-type pumps. Right-hand shaft rotation (RHS) orientation makes this pump compatible with standard small-block engine configurations, while the MP (mechanical pump) mount allows direct bolt-on installation without extensive adapter requirements. The robust internal design tolerates sustained high-RPM operation and synthetic oil formulations, making it ideal for engines pushing 450+ horsepower where marginal oiling systems fail prematurely.

High-performance engine builders, drag racing teams, and street performance enthusiasts benefit most from this pump's capacity and reliability under sustained load. The RHS MP mount configuration fits conventional American V-8 platforms including small-block Chevrolet, Ford, and similar architectures where factory or aftermarket block modifications accept standard mechanical pump mounting. Proper installation requires verifying your engine's pump cavity depth and confirming the pickup tube clearance; Moroso's proven engineering removes guesswork from your oiling system upgrade.
