SBC Louvered Windage Tra

The MILODON SBC Louvered Windage Tray is a steel oil management component engineered for small-block Chevrolet engines running a rear sump configuration. This louvered windage tray reduces oil windage loss—the parasitic drag created when the crankshaft churns oil during high-RPM operation—improving engine efficiency and reducing oil foaming that can compromise bearing protection. Constructed from cadmium-plated steel, the tray is positioned at the bottom of the engine block to intercept and redirect oil back into the sump while allowing critical oil flow to vital engine components.

The louvered design is the key to performance. Unlike solid trays, louvers create a path that separates air from oil, minimizing the churning effect at the crankshaft while maintaining proper oil circulation to bearings and journals. The cadmium plating protects against corrosion in both street and race environments. This windage tray is configured for driver-side dipstick mounting, making it a direct fit for small-block Chevy applications using rear sump oil pans. Weighing just 2 pounds, it imposes negligible parasitic loss while delivering measurable benefits in oil control and engine longevity.

This component serves engine builders, street rod enthusiasts, and performance rebuilds where oil management directly impacts reliability. In high-horsepower naturally aspirated or supercharged small-block applications, windage trays reduce pressure spikes in the pan and help maintain consistent oil levels at the pickup. The MILODON SBC windage tray is an economical upgrade for anyone upgrading a small-block Chevy pan system or rebuilding a rear-sump engine from the ground up.
