Go GX Rear Bearing
This bearing also fits O.S. MAX VZ-B and VZ-B V-Spec off-road competition buggy engines and 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 is open to allow oil to lubricate the bearings during use. If you run the OS VZ-B or VZ-B V-Spec engine, you probably want one of these bearings to keep the engine running well, especially if your engine starts making loud bearing noises at idle. This bearing will also fit any other .21 competition buggy engine that uses the same bearing dimensions.
