Question:

When Im looking at your seal sizes Is that the size of the axle O.D. and the hub Dim. it comes out of or is it the seal size itself?

The seals like the part # GS-2250DL has an outer diameter of 3.3376 inch which is the diameter of the bore on the hub that it is designed to fit and then the inner diameter is 2.25 inch which is the outer diameter of the spindle it fits on as well.

So if you measure your hub and the area a seal fits into measures 3.3376 inches then the # GS-2250DL and the outer diameter of the spindle you have measures 2.25 inch where a seal rides then this is the correct seal. If you have a different set of dimensions let me know and I'll see what you'd need.

Or you can check out the link I attached that has all of the seals we offer which you'd be able to select your dimensions from the filters to see what you'd need.
