GM LS Oil Pan Kit

The MILODON GM LS Oil Pan Kit (Part No. 30917-1) is a complete rear-sump solution engineered for General Motors LS-series engine swaps and high-performance applications. This six-quart capacity kit delivers the foundational lubrication infrastructure required for sustained engine operation, particularly in vehicles where stock oil pan geometry conflicts with frame rails, suspension components, or ground clearance requirements. The kit ships as a fully assembled system, eliminating the sourcing and compatibility uncertainties that typically accompany piecemeal oil pan installations.

This kit contains everything required for installation: the steel oil pan with cadmium plating for corrosion resistance, a matching gasket set, all necessary fastening hardware, a pickup tube assembly, and an integral windage tray to manage splash and foam under high-RPM conditions. The five-and-a-half-inch depth accommodates most frame setups without requiring extensive modification while the rear-sump design optimizes weight distribution and component clearance. The windage tray—a critical component in aggressive driving—reduces parasitic drag by channeling returning oil and controlling crankshaft turbulence, which improves cooling efficiency and helps maintain stable oil pressure across throttle transients.

LS engine swappers, whether building street rods, engine bay restomods, or off-road conversions, rely on this kit to eliminate fitment guesswork. The cadmium finish protects against rust in underbody environments where heat cycling and seasonal moisture exposure would compromise bare steel. Total package weight of 16.8 pounds reflects the robust construction without excessive mass penalty.

For buyers pursuing LS platform conversions or rebuilding an LS engine in its original application, choosing a matched kit like this eliminates compatibility questions and ensures the pickup tube geometry and pan clearance work together as a system—a practical advantage over mixing aftermarket components from different sources.
