This is a bearing kit by Avid RC for all versions of the MBX7 and MBX6. The bearings haven't changed through out their revisions.
Bearing kit is set to include our new Clutch bearings which are metal shielded at $2/ea and designed to handle the most extreme clutch conditions. It is recommended to always blow out the grease in your clutch bearings with an air compressor.
