Replacement front knuckle for Inferno MP

The Kyosho IF221B knuckle arm is supplied as a left and right replacement pair for Inferno MP Series NEO 3.0 & 4.0, cross referenced to Old Parts #: IF6B. These parts reestablish steering pivot alignment and correct suspension geometry affected by worn or damaged knuckles.

Fitment and role: the knuckle locates the front wheel hub and conveys steering movement from the servo linkages to the wheel, interacting with suspension links, hubs, and bearings. Confirm compatibility with your NEO 3.0 or 4.0 chassis and examine related fasteners and bearings before installation.

Installation notes: remove existing hub assemblies and steering links, fit the replacement left and right knuckles, replace any worn pins or bolts, and check that bearings rotate freely and steering throws are correct before track use. This component is for RC model maintenance and setup only.
