This Kyosho IF712-R front knuckle arm is the right-side steering knuckle for the MP11 chassis. It forms the pivot interface between the upper and lower knuckle sections and supports correct steering geometry in the front suspension layout.
As a replacement item the IF712-R corrects pivot misalignment caused by wear, helping to eliminate steering play. During tuning the knuckle arm condition will influence steering precision and how the front end communicates changes to setup.
If only the sleeve components are worn, they can be replaced separately using IFW647 KPI King Pin Sleeves (4 pcs), which are sold as an individual service part to avoid replacing the entire knuckle unit.
Stock this part in MP11 maintenance sets to keep steering accuracy and dependable suspension geometry for RC touring car applications.
