Yokomo YOKB4-415S B-MAX4 III Steering Block (Left & Right)  [YOKB4-415S]

Steering block upgrade for B-MAX4 III

This steering block pair is intended as a direct replacement for the steering knuckles on B-MAX4 III chassis, addressing the left and right sides together to preserve symmetry in the front end. Designed for RC-scale use only, the set focuses on the mechanical interface that locates wheel hubs and connects to suspension links.

Installation notes: remove the stock steering blocks one side at a time, retain existing hardware and bearings, check wheel bearing preload and link alignment during reassembly. The parts are used in the steering assembly to control toe, caster relationship and ackermann behavior; keep track of left/right orientation and confirm steering stops and servo horn clearance before final tightening.

Tuning guidance: swapping steering blocks can be part of iterative front-end setup — verify toe-in under static and dynamic conditions, adjust steering link lengths for desired ackermann, and inspect for play at tie-rods and kingpins after a few runs. Routine checks help maintain predictable steering feel.
