Oil Pan LS Engine Rear Sump Low Profile

The Oil Pan LS Engine Rear Sump Low Profile from Specialty Products Company is engineered for serious boaters and engine builders who demand reliable oil containment in high-performance LS-based marine powerplants. Whether you're running an LS swap in a performance fishing boat, a wakeboard machine, or a custom cruiser, this rear-sump aluminum pan keeps oil where it belongs—in the pan and away from your bilge. Designed specifically for applications where clearance matters, the low-profile design prevents pan-to-transom or pan-to-tunnel interference while maintaining adequate capacity for extended time on the water.

This rear-sump configuration holds 5.5 quarts of oil and features internal baffling to minimize oil surge during aggressive acceleration, cornering, and rough-water operation—critical for maintaining consistent oil pressure and preventing momentary starvation on the sump pickup. The aluminum construction resists corrosion in saltwater and freshwater environments while the 5.89-inch depth and low-profile geometry fit into tight engine compartments without sacrificing structural integrity. Black paint provides corrosion resistance and a finished appearance. The baffled internal design ensures oil flows evenly to the pickup tube, reducing aeration and extending oil and engine life in demanding conditions where consistent lubrication directly impacts reliability and longevity.

This pan is purpose-built for GM LS-series engine swaps in marine applications and suits boaters upgrading stock powerplants or building custom high-performance engines. The rear-sump design works best in craft where engine bay space is limited or where transom clearance is critical—common constraints in center console boats, bass rigs, and high-performance day cruisers. Installation requires basic mechanical skill and standard hand tools; ensure proper pan gasket sealing and confirm that the pan does not contact the boat's transom, tunnel, or any fuel or cooling lines during operation. Always verify clearance before final mounting and follow your LS engine builder's torque specifications for pan bolts.
