Part # EGM-243

Improved Racing's performance aluminum windage tray for LS family engines is a direct bolt-on replacement for the factory tray that clears up to a 4" stroke and works with both factory studs and ARP studs. This is a 3/4-length windage tray designed to clear shallow front oil pans such as the 4th Gen F-Body oil pan.

These windage trays are 100% bolt-on compatible with factory LS oil pans. No need to grind, modify, or add spacers to your windage tray. No more oil starvation issues due to misaligned pickup tubes. Just bolt this on and everything will line up like factory!

Improved Racing has designed this windage tray to maximize oil drainage while optimizing windage control. Made from aluminum, it weighs less than half as much as the steel factory tray. Compatible with all of the oil pans listed below, no modifications necessary.
