Hey Scott,

The Replacement Oil Cap Kit for 9,000-lb to 15,000-lb Dexter Axle # RG04-270 just comes with one oil cap. This is for:
9,000-lb Axles manufactured from October 1989 to July 2009
10,000-lb Axles manufactured prior to July 2009
12,000-lb and 15,000-lb Heavy-duty axles

It includes oil cap, O-ring, and plug.

Do you have an axle that fits this description? What trailer and axle are you working on? I'm happy to help more :).
