This Kyosho IF712-L front knuckle arm is the left-side steering knuckle intended as a service replacement for MP11-series 1/8-scale on-road cars. It serves as the pivot mount for the front wheel spindle and interfaces with the steering linkages and king pin assembly.
Use this part when restoring correct steering geometry after wear or after a collision; swap it one-for-one with the original knuckle to maintain factory alignment. Inspect mating surfaces and fasteners during replacement, clean bearing seats, and confirm free rotation of the wheel spindle before final tightening.
Note on related items: the sleeves that secure the upper and lower parts of the knuckle are sold separately as IFW647 KPI King Pin Sleeves (4 pcs).
