Billet Oil Pump Gear Set GM LS Standard Flow

The Billet Oil Pump Gear Set GM LS Standard Flow from Boundary Racing Pump is engineered for LS-series engine builders and performance enthusiasts who demand reliability during high-RPM operation and sustained power delivery. Whether you're building a daily-driver LS swap, a track-focused engine, or a forced-induction platform, proper oil circulation is non-negotiable—and this billet gear set ensures consistent pump performance without sacrificing flow rate. Designed as a direct replacement for OEM plastic or cast-iron gears, this kit addresses a critical wear point in LS engines, particularly in boosted applications where elevated operating temperatures and sustained load demand superior durability.

Boundary Racing manufactures this gear set from chromoly steel and polishes each component to exacting tolerances, minimizing friction and maximizing longevity compared to factory alternatives. The standard-flow rating ensures compatibility with stock pump bodies and original oil galleries, eliminating the need for housing modifications or blockage concerns. Chromoly's superior hardness resists wear from extended full-throttle runs, while the precision-cut gear teeth maintain tight tolerances to reduce internal leakage and sustain stable oil pressure across the entire RPM band—critical for protecting rod and main bearings, cam lobes, and hydraulic valve lifters under stress.

This replacement gear set is ideal for LS1, LS2, LS3, LS7, and other small-block LS variants, making it a must-have service item for engine builders stepping up to billet internals or refreshing a high-mileage platform. Installation requires removing the front cover and timing chain, a straightforward job for any mechanic familiar with LS architecture. The polished finish resists corrosion and looks professional inside the engine bay, while the standard-flow design pairs seamlessly with stock oil pumps and aftermarket billet pump housings. Pair this gear set with quality synthetic oil and a robust oil cooler for maximum longevity in turbocharged, supercharged, or naturally aspirated builds.
