Billet Oil Pump Gear Set GM LS High Flow

The Billet Oil Pump Gear Set GM LS High Flow is a precision-engineered upgrade designed for LS engine builders and performance enthusiasts who demand maximum oil circulation under extreme operating conditions. Factory stamped steel gears are prone to wear, cavitation, and inadequate flow at high RPM, making this billet alternative essential for street, strip, and race applications where reliability and consistent oil pressure are non-negotiable. Whether you're running a naturally aspirated stroker, supercharged street engine, or dedicated race motor, this gear set ensures your bearings and critical components receive optimal lubrication throughout the rev range.

Manufactured by Boundary Racing Pump and machined from premium billet material, this high-flow gear set increases oil volume delivery compared to stock LS pump internals, reducing operating temperatures and parasitic drag on the crankshaft. The optimized tooth geometry and tighter tolerances minimize cavitation—a critical failure point in stock pumps at elevated engine speeds—while the billet construction eliminates porosity issues inherent to cast alternatives. Enhanced flow characteristics maintain pressure stability across the powerband, protecting expensive internals like main and rod bearings from starvation during sustained high-RPM operation or aggressive throttle transients.

This gear set is compatible with all LS-platform engines, including LS1, LS2, LS3, LS7, LSX, and truck variants, making it a versatile choice for any LS build. Installation requires disassembly of the existing oil pump housing and replacement of the wear components—a straightforward procedure for experienced builders or professional machine shops. Whether you're targeting 500 hp or 1000+ hp, the Billet Oil Pump Gear Set GM LS High Flow delivers the flow and reliability demanded by modern high-performance and race applications.
