LS Oil Pan Cast Alum

The LS Oil Pan Cast Alum from ALLSTAR PERFORMANCE is a purpose-built engine sump designed for GM LS-series engine swaps and modifications. This rear-sump aluminum oil pan is engineered for builders and enthusiasts who demand reliable oil management in high-performance applications, street rods, and custom engine installations. Cast from lightweight aluminum, it delivers the structural integrity needed for sustained operation while reducing overall engine bay mass—a critical consideration when fitting LS powerplants into platforms never originally designed for them.

This oil pan features a 6-quart capacity and stock depth design, allowing fitment in tight engine bays without requiring extensive frame or chassis modifications. The rear-sump configuration positions the oil pickup at the engine's rear, a layout preferred in mid-engine conversions and installations where the engine sits further back in the chassis. Cast aluminum construction provides excellent thermal properties—dissipating heat more efficiently than steel—while maintaining rigidity under acceleration and cornering loads. The natural finish allows easy inspection for leaks and integrates cleanly into any engine compartment aesthetic.

Mechanics and fabricators installing LS engines in classic cars, hot rods, and custom platforms will find this pan essential for maintaining proper oil supply to the engine under all driving conditions. Its stock depth design means it clears most stock and modified K-member geometries without requiring custom bracketry or pan relocation hardware. Weighing 16.6 lbs, the aluminum construction keeps rotating and reciprocating mass to a minimum compared to cast-iron alternatives, supporting higher RPM operation and improved throttle response. Verify fitment with your specific chassis and oil pickup configuration before installation to ensure proper clearance and correct oil level management.
