The Motobilt Sterling ABS block off plate was designed for those who are swapping the Sterling rear axle into their Jeep. This plastic ABS plug is no longer used when swapping the Sterling axle into a Jeep. Due to the brackets involved in the Sterling axle swap often the vent tube on the axle tube is no longer accessible. If this is the case you will need to drill and tap a hole for a vent tube.
The block off plate is made of 3/16 inch plate steel and ships bare metal.
