B-Max4 Compatible Front Inner Arm Pins (4) - YOKBM009A Yokomo  [YOKBM009A]

Front inner arm pin function on B-Max4

This YOKBM009A package contains four front inner suspension arm pins designed for use with the B-Max4 chassis, intended as direct replacement items to keep the front suspension secure and predictable.

Role and fit: the pins anchor the inner side of the front suspension arm into the bulkhead or hinge assembly, helping the suspension hold geometry and absorb loads. Replace pins that bend or develop play to avoid compromised steering feel.

Installation tips: remove the wheel and slacken the related steering or suspension fixings, withdraw the worn pin, then push or press the new pin into place until the arm moves smoothly with minimal clearance. Check retaining clips and set screws specific to the B-Max4 and swap them if worn. Routine RC tools will suffice.

Tuning considerations: loose inner pins can change front camber and toe behavior; renewing pins is a standard step in setup checks before experimenting with shock or arm adjustments. Re-align components and run a quick test to confirm handling improvements.
