This is a ceramic front engine bearing from TKO Competition Development designed to fit the O.S. MAX .21 RG, VZ-B and VZ-B V-Spec off-road competition buggy engines. This bearing will also fit any other .21 competition buggy engine that uses the same bearing dimensions, such as the RB Concepts WS7, WS7II, Novarossi P5, Plus 21-5 etc (in fact most .21 or higher engines use this front bearing). The bearing dimensions are 7mm inner, 19mm outer and 6mm thick.
These are the same bearings used by Ed Bridges from EB Mods for the O.S. V-Spec modified engines.
