This is a TKO rear Ceramic engine bearing designed for the O.S. MAX VZ-B, VZ-B V-Spec, and V-Spec 2 off-road buggy engines. This bearing also fits recent Novarossi and RB Concepts engines that require the special 25.4 mm rear bearings such as the P5 and C5 engines. The bearing dimensions are 14mm inner, 25.4mm outer and 6mm thick. This bearing will also fit any other .21 competition buggy engine that uses the same bearing dimensions.
IMPORTANT: This bearing needs to be installed so that the balls face the rear of the engine (towards the backplate), for proper lubrication.
