GM LS Oil Pan Retrofit

The GM LS Oil Pan Retrofit from Holley is purpose-built for LS-series engine swaps and custom builds where rear-sump oiling architecture is required. Whether you're dropping an LS powerplant into a vintage chassis, upgrading a street rod, or engineering a high-performance swap application, this retrofit kit eliminates the guesswork of adapting modern LS oil delivery to non-OEM installations. It addresses the critical challenge that many LS enthusiasts face: maintaining proper oil flow and cooling capacity when original pan designs are incompatible with engine bay geometry or suspension components.

Built from aluminum for lightweight strength and durability, this retrofit pan features a 6.125-quart capacity with a 5.438-inch sump depth—engineered to balance adequate oil volume for sustained RPM operation while maintaining clearance in tightly packaged engine bays. The complete kit includes the pan body, cover, pickup tube, mounting studs, sump port plug, and tray, eliminating the need to source components separately. Natural finish aluminum resists corrosion while allowing easy inspection of oil level and condition, and the integrated sump design maintains proper oil evacuation during cornering and acceleration to prevent starvation at critical moments.

Ideal for fabricators, restoration shops, and serious DIY builders, the GM LS Oil Pan Retrofit integrates seamlessly with all GM LS-series engines including LS1, LS2, LS3, LS7, and LSx variants. Installation requires basic mechanical skill and standard tools, making it accessible for garage builds and professional shops alike. This retrofit delivers the reliability and engineered design of OEM-quality components at a fraction of custom fabrication costs, ensuring your LS swap maintains oil system integrity and longevity regardless of application—from street machines to strip warriors.
