This is an RC-scale front lower suspension pin for the KYOSHO FW05-R and FW05RR platforms, listed under part number FW05-RR003B.
The pin acts as the pivot for the front lower suspension arm, keeping alignment and reducing play at the lower joint. Replacing worn pins helps restore steering precision and consistent suspension geometry without changing other setup items.
Installation notes: this pin is fitted in place of the stock front lower suspension pin on FW05-R/FW05RR chassis. Remove the front lower arm and carrier to swap the part, then check suspension travel and steering clearance through full lock.
Tuning role: a precisely finished 64-Ti pin can limit lateral movement at the lower arm pivot and maintain predictable roll centre behaviour, making it a useful maintenance or precision replacement part during setup work.
