This Kyosho IF712-R front knuckle arm serves as the right-side steering knuckle for the MP11 chassis. It forms the pivot point between the upper and lower knuckle pieces and helps keep steering geometry stable in the front suspension layout.
As a service replacement the IF712-R corrects pivot misalignment caused by wear or damage. When setting up or tuning an MP11, the knuckle arm's condition will influence steering precision and the feedback from the front end, so it is a primary item to inspect if steering feels loose or inconsistent.
The retaining sleeves for the knuckle halves are offered separately as IFW647 KPI King Pin Sleeves (4 pcs), available as a service spare to refresh the sleeve wear without replacing the entire knuckle assembly.
Include this part in MP11 maintenance spares to preserve steering accuracy and suspension geometry for competitive RC touring performance.
