The Yokomo B8-414BA 4.8mm king pin ball is a recommended replacement when servicing the front end of a BD8 2018. It secures the front knuckle to the hub carrier and helps maintain predictable steering response and handling on the track. The ball measures 4.8mm for an accurate fit in the hub carrier.
This package contains two king pin balls plus collars for straightforward swapping of worn components. The parts are made for the MRTC-BD818 and MRTC-BD818A chassis, so they match those BD8 2018 variants. Use them during routine checks or when fine-tuning suspension geometry to keep steering precise.
