Part # EGM-241

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.

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 for a weight savings of approximately 1.4 lbs. Compatible with all of the oil pans listed below, no modifications necessary.
