LT Engine Series Extended Sump Conversion Oil Pan
When fitting an LT powerplant into a front steer chassis the LT engine series Conversion Oil Pan (Extended Sump) secures oil supply under lateral loads with a five quart reservoir positioned at the lowest point. This pan's extended sump design ensures the pickup stays submerged during hard cornering channeling fluid back to the pump inlet and avoiding pressure loss. Lightweight aircraft grade aluminum sheds weight up front and draws heat from circulating oil to maintain stable temperatures under sustained load. Technicians retain factory routines with the billet adapter for AC Delco PF48 filters and direct fit for GM dipstick 12643278 plus its tube for precise oil level checks and straightforward service.
Extended Sump Geometry for Steady Oil Supply
The extended sump design on the LT engine series conversion oil pan creates a deep five quart reservoir that ensures the oil pickup remains submerged during aggressive cornering or sustained lateral loads. By positioning the pickup tube at the lowest point, it channels returning fluid back to the pump inlet to eliminate pressure loss and guard against starvation events. This geometry preserves crankshaft bearing health and oil film integrity under momentary level shifts. Drivers and track enthusiasts benefit from consistent lubrication across spirited turns and extended sessions.
Aircraft Grade Aluminum Structure for Efficient Thermal Management
Crafted from aircraft grade aluminum, this pan sheds front end mass to improve chassis balance and steering feel. The metal's high thermal conductivity draws warmth from circulating oil, preventing temperature spikes under continuous load. Its smooth interior resists corrosion and limits contaminant buildup, ensuring reliable pump performance over service intervals. Technicians will notice stable oil temperatures even in demanding applications thanks to optimized heat extraction and lightweight strength.
Precision Billet Adapter for Leak Free Filtration
Integrated into the pan is a billet oil filter adapter that accepts AC Delco PF48 cartridges with exacting tolerances. The machined interface aligns the filter securely while the O ring seal prevents seepage common with stamped fittings. This rigid connection maintains uninterrupted flow and full filtration efficiency, reducing the risk of debris reaching critical engine components. Maintenance crews appreciate the simple swap process using factory filters and familiar installation angles.
Direct GM Dipstick Integration for Accurate Level Checks
Compatibility with GM dipstick 12643278 and tube 12652951 preserves original service routines without aftermarket modifications. The tube mounts directly to the pan to eliminate flex and vibration that can skew measurements. Consistent tube placement and a solid mounting boss deliver repeatable oil level readings, helping to prevent overfill or foam formation. This direct fit approach keeps routine inspections aligned with OEM specifications and streamlines every oil check.
Engineered for precise fit into your LT chassis with dependable oil management that supports consistent lubrication under sustained loads.
