This front pivot shaft is produced for the Kyosho Mini Inferno layout and carries the part designation MIF-021/BU. It functions as the central pivot for the front suspension links, recovering intended articulation and minimising play that degrades repeatable handling.
For best results during replacement, remove the front arms, fit the new shaft, confirm unobstructed link rotation, and verify no contact with steering components. Cycle the assembly through full travel and recheck alignment and clearances before final tuning for on-track setup.
From a setup perspective the pivot shaft is a precision wear item; replacing it restores predictable steering geometry and repeatable suspension behaviour, which is critical when optimising damping and roll characteristics for competition.
