The Yokomo BM-414 king pin kit supplies a set of four standard king pins for B-MAX2 and B-MAX4 RC touring car platforms. These components act as direct replacements to restore steering pivot function after regular wear or heavy track use.
Installation is straightforward for those experienced with front-knuckle service: remove the knuckle, withdraw the worn pins, and press or fit the replacement king pins into the pivot bore while observing the chassis manufacturer's recommended clearances. After fitting, confirm steering geometry and ensure the pivot travel operates without binding.
King pins play a role in steering feel and front-end wear patterns during setup and tuning. When changing these pins, inspect associated parts such as bushings, ball bearings, and fasteners to maintain consistent steering response on track.
