This front lower suspension pin is made for KYOSHO FW05-R and FW05RR chassis and is catalogued as FW05-RR003B.
Functionally the pin defines the rotational axis of the front lower arm, preserving alignment and reducing play at the lower joint. Renewing the pivot restores repeatable steering inputs and stable suspension geometry without altering arm pick-up points or link lengths.
Installation guidance: remove the front lower arm and carrier to replace the existing pin with this part. On reassembly verify free movement through suspension travel, correct steering throw and absence of interference at full lock.
Setup implications: a precisely produced 64-Ti pin reduces lateral slop at the lower pivot, aiding predictable roll centre behaviour and consistent handling during tuning and track sessions.
