YOKBM009A B-Max4 Front Inner Suspension Arm Pin Set by Yokomo  [YOKBM009A]

Front inner arm pin role and fitment

The YOKBM009A set includes four front inner suspension arm pins intended for the B-Max4 series, supplied as replacement spares to preserve correct mounting and predictable suspension action.

Role and fit: these pins hold the inner end of the front suspension arm into the bulkhead or hinge mount, keeping steering geometry stable under load and during adjustments. Replace them when signs of wear or play affect steering precision.

Installation tips: remove the wheel and loosen the steering and suspension fasteners, extract the old pin, then slide or press the new pin until the arm pivots with minimal slop. Reuse or replace retaining clips and set screws on the B-Max4 as needed. No specialist equipment is required.

Tuning considerations: degraded inner pins can alter camber and toe, impacting handling; swapping in fresh pins is a simple check before altering shock rates or arm geometry. After fitting, re-check tracking and carry out a brief test session to confirm expected steering response.
