Kyosho IF221B - Knuckle Arm (L,R/IF6B) replacement pair for Inferno MP Series  [KY-IF221B]

Knuckle arm spare for Inferno MP Series

This Kyosho IF221B knuckle arm is an RC-scale spare designed as a left and right replacement pair for Inferno MP Series NEO 3.0 & 4.0 models, referenced from Old Parts #: IF6B. The component restores steering pivot points and maintains intended suspension geometry when a worn or damaged knuckle affects handling.

Fitment and role: the knuckle arm locates the front wheel hub and transfers steering input from servo linkages to the wheel, working together with suspension links, hubs, and bearings. When replacing, confirm compatibility with your NEO 3.0 or 4.0 chassis and inspect associated hardware and bearings for wear before assembly.

Installation notes: remove existing linkages and hubs, swap the left and right knuckles as needed, reuse or replace pins and hardware as required, and verify free rotation of wheel bearings and correct steering travel before track use. This part is intended strictly for RC model maintenance and setup adjustments.
