Moroso 22943 Louvered Windage Tray - for GM LS Engines with ARP Main Studs

The Moroso 22943 is a precision-engineered louvered windage tray designed specifically for GM LS engines equipped with ARP main cap studs. This performance component helps control oil movement in the crankcase, reducing parasitic horsepower loss caused by oil windage while improving oil return to the sump.

Key Features:

• Louvered design maximizes crankshaft clearance while controlling oil effectively
• Engineered specifically for GM LS engine blocks with ARP main cap stud installations
• Reduces oil windage and aeration for improved oiling system efficiency
• Helps prevent oil from being whipped by the rotating crankshaft assembly
• CNC-machined for precise fit and optimal performance
• Constructed from durable materials to withstand high-performance engine environments

Windage trays are essential components in high-performance and racing engines where crankshaft speeds generate significant air turbulence in the oil pan. By installing the Moroso 22943, you'll help maintain consistent oil pressure and reduce parasitic drag on the rotating assembly, translating to measurable horsepower gains and improved engine longevity.
