This Kyosho IF221B knuckle arm set is an aftermarket left and right replacement for Inferno MP Series NEO 3.0 & 4.0, listed against Old Parts #: IF6B. The knuckles restore correct steering geometry and help recover handling lost to damaged steering pivots.
Fitment and role: knuckle arms locate the front hub and transmit steering forces from servo linkages to the wheel, coordinating with suspension links, hubs, and bearings. Confirm your chassis variant (NEO 3.0 or 4.0) and inspect hardware before fitting.
Installation notes: remove hubs and linkage hardware, replace the knuckles left and right as required, renew pins or fasteners if worn, and verify bearings turn freely and steering travel is correct prior to running. Intended for RC maintenance and setup use.
