DS Oil Pump 2-Stage Tri-Lobe LHS w/FP Drive

The DS Oil Pump 2-Stage Tri-Lobe LHS with FP Drive by MOROSO (MPN 22377) is a premium engine oil circulation system designed for high-performance and modified engines that demand superior lubrication under demanding conditions. This left-hand shaft configuration is engineered for builders and enthusiasts who require maximum oil delivery in naturally aspirated or forced-induction applications. Whether you're building a stroker motor, running extended track sessions, or upgrading cooling capacity in a modified powerplant, this pump delivers the reliable oil flow that keeps bearing surfaces protected and engine temperatures stable.

The two-stage tri-lobe design is the key to this pump's effectiveness—the first stage handles low-speed circulation for idle and cruise conditions, while the second stage engages under load to boost pressure and volume when your engine is working hard. The FP (fuel pump) drive integration allows flexible mounting and clean integration into tight engine bays, eliminating the need for external drive accessories. This tri-lobe rotor configuration minimizes pulsation and noise while maximizing displacement per revolution, delivering consistent flow rates across the entire RPM range. The robust construction and precision manufacturing ensure durability through thousands of miles of high-rpm operation, making it ideal for race engines, big-displacement builds, and performance street applications.

Engine builders and performance mechanics choose the DS Oil Pump 2-Stage Tri-Lobe for custom small-block and big-block applications where OEM pumps fall short. The left-hand shaft orientation and FP drive mounting make it compatible with traditional belt-drive systems and custom cradles common in street rods, race engines, and restomod conversions. Installation requires proper orientation verification and alignment with your engine's accessory drive configuration; consult your build manual or engine supplier for specific mounting requirements. With a shipping weight of 7.75 lbs and compact dimensions, this pump integrates cleanly into most engine compartments while delivering the oil pressure and volume that separates a bulletproof build from an overheated disappointment.
