GM LS CT Oil Pan 8qt 4-in Deep Rear Sump

The GM LS CT Oil Pan 8qt 4-in Deep Rear Sump is purpose-built for LS engine swaps, street rods, and custom automotive builds where traditional pan geometry conflicts with frame rails, headers, or suspension components. Designed by KEVKO, a brand trusted by engine builders and fabricators for nearly three decades, this rear-sump configuration moves the oil pickup to the rear of the engine bay, solving clearance issues that plague front-sump conversions while maintaining robust 8-quart capacity for extended cooling intervals.

The 4-inch deep sump design maximizes oil volume and thermal mass without excessive ground clearance penalties—critical for low-stance builds where underbody protection and departure angles matter. Constructed from quality materials engineered to withstand sustained high-RPM operation and sustained boost pressure environments, the pan features a rear-sump configuration that integrates seamlessly with LS engine oiling architecture while accommodating the structural and packaging demands of custom chassis. The 8-quart capacity supports extended oil change intervals and provides superior heat dissipation during spirited driving or track use, reducing oil temperature by keeping more fluid in circulation.

This pan excels in LS-powered street rods, C5/C6 Corvette retrofits, truck conversions, and tube-frame race cars where conventional sump placement is impossible. Installation requires custom exhaust routing and oil line fabrication but rewards builders with a clean engine bay layout, improved weight distribution, and the flexibility to run aggressive lowering springs or custom suspension geometry. Weighing 16 pounds and measuring 13 by 8 by 23 inches, it demands careful packaging during installation but delivers uncompromising cooling capacity and reliability for serious enthusiasts unwilling to compromise on either performance or fitment.
