If you are building or upgrading an engine, you have probably heard about windage trays but might wonder if they are worth the investment. These simple metal shields sit between the crankshaft and oil pan, preventing the rotating assembly from churning oil into a froth. That reduces parasitic drag, improves oil pressure stability, and protects your engine at high RPM.
This guide reviews ten popular windage trays across different engine platforms, from LS and small block Chevy to Subaru EJ series. You will learn what each product offers, its compatibility, and what to consider before buying. Whether you are restoring a classic or pushing a modern build, this list helps you choose the right tray for your needs.

Included with the pickup is a windage tray that directs oil from the upper crankcase down into the pan, reducing aeration. This combination ensures consistent oil pressure even during high-RPM track use. The stainless steel construction is lightweight, durable, and heat-resistant.

Buyer’s Guide: What to Consider
Choosing the right windage tray depends on your engine type, performance goals, and installation preferences. This guide highlights key factors to consider, helping you make an informed decision that matches your vehicle and budget.
- Engine Compatibility: Ensure the windage tray matches your engine family and specific displacement. For example, LS1 trays fit 1998-2002 Camaro/Firebird, while LS3 trays are for newer GM engines. Subaru trays are for EJ series. Check your engine code and year.
- Material and Build Quality: Most trays are steel, but quality varies. Look for stainless steel (like IAG) for corrosion resistance and durability. Louvered designs are common and effective. Cheaper trays may be thinner, so consider the operating conditions.
- Installation Requirements: Windage trays mount to the main bearing caps, requiring oil pan removal. Some kits include necessary bolts or studs, while others do not. Check if you need additional hardware like the LANDSIN nuts. Factor in labor time if you are not doing it yourself.
- OEM vs. Aftermarket: OEM trays (GM Genuine, FORTLUFT) guarantee exact fit and factory performance. Aftermarket options (Moroso, IAG) may offer enhanced features like thicker material or better design. Decide based on your budget and performance goals.
- Included Components: Some products are just the tray, others include baffles, bolts, or oil pickups. Kits like EngineQuest provide everything needed, simplifying installation. Consider what you already have and what you need to complete the job.
Conclusion
Windage trays are a simple yet effective upgrade for any engine that sees high RPM or aggressive driving. They reduce oil aeration, maintain oil pressure, and can even free up a few horsepower. Whether you drive an LS-powered F-body, a small block Chevy, or a turbo Subaru, there is a tray on this list for you.
For LS1 owners, the LOSTAR or UnayKolb trays offer direct OEM fit. Subaru enthusiasts should consider the IAG Performance options for durability. If you want a complete kit, the EngineQuest set is ideal. Always verify compatibility and installation requirements before purchasing. Choose a tray that fits your engine and driving style, and you will protect your investment for years.
