This component is a front lower suspension pin made for the KYOSHO FW05-R and FW05RR chassis, referenced as part FW05-RR003B.
As the pivot for the lower suspension arm, the pin retains alignment and reduces play at the lower joint. Renewing a worn pin restores more consistent steering feel and suspension geometry without altering other settings.
Fitment notes: the pin replaces the original lower pin on FW05-R/FW05RR models. Disassemble the front lower arm and hub carrier to change the pin, then confirm clearance and repeatability across steering lock.
Tuning notes: using a tight-tolerance 64-Ti pin helps cut lateral slop at the pivot and keeps roll centre behaviour stable, which helps when dialing in handling for track or club runs.
