If you have 7,000 to 9,000 lb Dexter axles on your tri-axle trailer, the oil cap kit you need for each hub is part # RG04-230.

These are designed to fit 7-9k axles with 8-bolt hubs and includes the oil cap, plug, and O-ring. Just to be sure it will work the threading measurement is 2-7/8 inches outside diameter.

This kit will fit older 6K, 8K, and 9K Dexter axles before 10/1989.

if you do not have 7K to 9K axles on your trailer let me know what size axles you have and I can check to see if we have the oil caps available that will work for you.
