Made from high-grade composite, it provides a reliable seal and steady operation whether you are racing, testing, or performing routine maintenance.
Manufactured from a reinforced composite blend, the XRAY 364920 cover resists impacts and wear to extend service life on both front and rear differentials. The material helps keep dirt and moisture out so the drivetrain stays cleaner and performs more consistently over time.
