These bearings came with the ProTek clutchbells I use and I was impressed with the quality. Much better than other $1 bearings with the exception of the Boca brand. They fit perfectly on the crankshaft, a big issue with other bearings of lesser quality and the seem to be sealed a little better too, and come full of grease like I prefer. I can clean these bearings after a raceday, re-oil them and get at least another raceday out of them if not two. A big difference from the others I've used.
