SBC Diamond Screen Tray

The SBC Diamond Screen Tray from MILODON is a precision windage management component engineered for small-block Chevy engines seeking optimal oil circulation and crankcase ventilation. This steel windage tray serves as a critical barrier between the rotating crankshaft assembly and the engine sump, preventing oil turbulence and aeration that degrades lubrication efficiency during high-RPM operation. Whether you're building a street performance engine, preparing for track duty, or restoring a classic small-block platform, this diamond stripper design directly improves oil control and engine reliability under sustained load.

Constructed from cadmium-plated steel, the SBC Diamond Screen Tray features a distinctive diamond pattern that enhances structural rigidity while maximizing oil return pathways to the pan. The stripper design reduces windage losses—the drag created when the crankshaft churns oil—allowing the pump to deliver cleaner, cooler lubricant to bearing surfaces and the main gallery. Cadmium plating provides superior corrosion resistance and durability in high-temperature engine environments where standard finishes would degrade. Precision dimensioning (10.65 × 6.8 × 18.25 inches) ensures a secure fit within the small-block Chevy pan without obstruction to rotating components or crank counterweights.

Serious engine builders and weekend warriors alike specify windage trays to maintain consistent oil pressure, reduce bearing wear, and unlock marginal horsepower gains during hard driving. This tray fits all small-block Chevy variants (265–400 cubic inches) and integrates seamlessly with stock or performance oil pans. Installation is straightforward—the tray mounts via existing pan fasteners and requires no modifications to engine block or accessory systems. At 3.43 pounds, weight penalty is negligible compared to the measurable improvements in oil delivery and engine longevity that result from controlled crankcase ventilation and reduced aeration.
