This is the Profile Axle Bearing Shim. If your hub has a slight side to side wobble, then the Profile Hub Shims may fix it. They are designed to be installed behind the bearing, requiring the hub to be disassemble and then reassembled. There are Full Instructions on the Tech section of Profile Racing's website should you choose to fit it yourself! The Profile Axle Bearing Shim are only .005" each. If there is a significant wobble to your hub, a shim is probably not going to make a difference, the wobble may be caused by a larger issue, such as worn out bearings or damaged parts. Putting more than 2 shims into a hub isn't needed in the vast majority of cases.
