This simple plate allows you to block off the factory Ford ABS sensor hole on your 8.8 axle. If your axle didn't come with the sensor in place, use this to keep oil from slinging out the top of your diff. The plate comes zinc plated and includes the bolt to secure it in place. Create a nice tight seal with some RTV sealant and you will never have to worry about leaking or mud and grime getting into your diff! The simple 2 minute installation will give you peace of mind.
