Drop bar models are size specific. If you are unsure which size ball holder you need, place your drop bar in your receiver.

If you have a 2″ receiver, and the drop bar shank fits your 2″ receiver, you will need the SIMPLE or SCALE ball holder.

If you have a 2-1/2″ receiver, and your drop bar shank fits a 2-1/2″ receiver, you will need the HD SIMPLE or SCALE ball holder.
