rear= 14x25.4x6
front= 7x19x6

The bearings are the same size as a RB C4 or C5. Not a C6, C6 has a slightly larger rear bearing 14x25.8x6

Here is a link to Boca's MX series bearings. I recommend these bearings, they do exactly what they are claimed to do. The front bearing in this kit seals quite well. They are on sale right now and you can take advantage of Boca's free regular shipping.
