Front Inner Suspension Arm Pins for B-Max4 - YOKBM009A Yokomo  [YOKBM009A]

Replacement inner pin for front suspension

The YOKBM009A set supplies four front inner suspension arm pins intended for the B-Max4 platform, offered as straightforward spares to maintain correct mounting and suspension behaviour in scaled RC cars.

Role and fit: these pins secure the inner edge of the front suspension arm to the chassis bulkhead or hinge mount, maintaining alignment and range of motion during cornering and impacts. Replace pins that exhibit wear, bending or looseness which can upset steering precision.

Installation tips: take off the wheel and slacken the nearby steering and suspension fasteners, extract the old pin, then insert the replacement until the arm pivots smoothly without excess play. Confirm any retaining clips or grub screws used on your B-Max4 and replace them if worn. No specialist tools are required beyond typical RC tool kits.

Tuning considerations: worn inner pins can shift camber and toe settings; fitting fresh pins is a basic maintenance task before changing shock rates or arm geometry. After installation, re-check tracking and perform a short run to validate handling.
