The Yokomo BM-414 king pin set provides four standard replacement pins for use with B-MAX2 and B-MAX4 RC touring cars. These parts are designed to restore steering pivot performance that has degraded through normal running.
Installation follows common front-knuckle procedures: remove the knuckle, take out the worn pins, then press or fit the new king pins into the pivot bores while observing the chassis manufacturer's clearance recommendations. Once fitted, check steering geometry and ensure the pivot movement is smooth and free of binding.
King pins contribute to steering feel and the pattern of wear at the front end. When replacing them, inspect associated items such as bushings, bearings, and fasteners to ensure a comprehensive maintenance job and steady handling on track.
