B-Max4 Front Inner Suspension Arm Pin Set (4 pcs) - YOKBM009A by Yokomo  [YOKBM009A]

B-Max4 Front Inner Arm Pin Overview

This YOKBM009A kit contains four front inner suspension arm pins made for the B-Max4 chassis, supplied as replacement spares to restore correct arm mounting and control in RC models.

Role and fit: these pins fasten the inner end of the front suspension arm to the bulkhead or hinge point, preserving steering geometry and suspension travel under load. Replace them when the originals show wear, bends, or play that degrade handling.

Installation tips: remove the wheel and loosen associated steering or suspension fasteners, pull out the worn pin, then slide or press the new pin into place until the arm pivots cleanly with minimal slop. Inspect and reuse or renew any retaining clips or set screws on the B-Max4 assembly. Standard RC maintenance tools are sufficient.

Tuning considerations: excessive play in inner pins alters camber and toe at the front; changing pins is a basic service step before modifying shocks or arm angles. After fitting new pins, recheck alignment and run a short test to confirm predictable steering and suspension response.
