Hello Steven,

Thanks so much for measuring the hub bore with your calipers, that is super helpful.

With a measurement of 2.745, you will want the Bearing Buddy Bearing Protectors, Model 2717, Chrome Plated (Pair) # BB2717. The # BB2717 is designed to fit a hub bore of 2.717" and works with outer bearings 14124 and 14125A, which tells me you are running a 7K axle. If you used a digital caliper, it would not be unusual for the measurement to be just slightly off.

You will need to order one set of the # BB2717 per axle.

What kind of trailer are these going on, a 5th wheel?
