DS Oil Pump Tri-Lobe 5-Stage LHS Mount

The DS Oil Pump Tri-Lobe 5-Stage LHS Mount from MOROSO is a precision-engineered oil pump designed for serious engine builders and performance mechanics who require reliable, high-volume lubrication under extreme conditions. This left-hand-side mount configuration is ideal for applications where standard oil pump placement conflicts with custom chassis layouts, supercharger installations, or tight engine bay modifications.

The tri-lobe rotor design enhances the pump's effectiveness by increasing displacement per revolution, resulting in higher volume delivery with lower parasitic drag compared to conventional gear-type pumps. The five-stage design features multiple internal chambers that optimize flow regulation and maintain pressure consistency across variable engine speeds, effectively preventing cavitation at startup and ensuring steady supply pressure under load.

This oil pump is particularly beneficial for those building competition engines, high-RPM street machines, or race-prepared platforms. Its LHS mount configuration is a requirement for many LS platform conversions and big-block Chevys with modified pan designs, making it a versatile choice for custom fabrications.
