Moroso 21813 Wet Sump Oil Pan with Crank Scraper and Windage Tray

The Moroso 21813 is a high-performance wet sump oil pan engineered for serious race and high-performance street applications. This pan is specifically designed to accommodate stroker crankshafts up to 4.125-inch stroke with most aftermarket steel connecting rods, making it ideal for high-displacement small block Chevy builds.

Key Features:

• Wet sump design with enhanced oil control system
• Clears 4.125-inch stroke crankshafts with most steel connecting rods
• Compatible with 4-bolt main caps from Dart, GM, and Merlin blocks
• Three trap door baffles with two oil return runners for superior oil control during hard acceleration and cornering
• Built-in crank scraper to reduce windage and free up horsepower
• Removable screen-style windage tray for easy maintenance
• Anti-slosh baffle system keeps oil at the pickup during aggressive driving
• Precision-welded construction for maximum strength and durability

This oil pan combines multiple oil control technologies to ensure consistent oil pressure and reduce parasitic power loss from windage. The integrated crank scraper works with the windage tray to keep oil off the rotating assembly, while the trap door baffles and runners prevent oil starvation during high-G maneuvers. Ideal for road racing, drag racing, and high-performance street use where oil control is critical.
