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 serious engine builders and mechanics who demand superior oil delivery in high-performance and racing applications. This tri-lobe design represents a significant step up from traditional gear-driven oil pumps, providing consistent, reliable pressurization across the entire RPM band. Whether you're building a street machine, bracket racer, or dedicated competition engine, this pump delivers the consistent flow rates required for sustained power output and engine longevity.

The tri-lobe configuration uses three lobes instead of the conventional two, resulting in more frequent delivery pulses and smoother, more constant oil pressure throughout the engine's lubrication system. The 3-stage design enables superior pressure regulation and flow characteristics, reducing cavitation and ensuring every gallery receives adequate protection under load. The RHS (right-hand shaft) orientation accommodates specific engine configurations, while the MP Mount (mid-plate mounting) offers flexible installation on engines using modern pump mounting standards. This pump measures 10.7 x 10.5 x 14.25 inches and weighs 8.71 lbs, making it a substantial, precision-engineered component built to MOROSO's exacting standards.

Professional engine builders, race teams, and DIY enthusiasts who are maximizing output and reliability in modified or race engines will appreciate the engineering behind this pump. The tri-lobe design is particularly valuable in high-RPM applications where traditional pumps struggle to maintain adequate pressure, and the 3-stage configuration makes it ideal for forced-induction, nitrous, or heavily boosted builds. Verify your engine's shaft orientation and mounting configuration before installation to ensure proper fitment with your specific platform and oil system setup.
