AEV Hardware Kit for M8 Beadlock Ring

For added convenience, AEV Differential Covers feature an oversized oil fill port located on the top of the cover. This fill port not only allows you to easily add fluid in the field if axle repairs are necessary, but also doubles as an inspection port, allowing the user to see inside the differential, inspect ring gear teeth, look for water intrusion or even use a dial indicator to inspect for problems without ever removing the cover.
