Fine Tune Steering with Kyosho IF420B Collars

If you want tighter, more repeatable steering on your MP9, the Kyosho IF420B knuckle arm collars are a simple upgrade that improves control. They sit at the heart of the steering linkage and help keep steering movements accurate under load.

Fitment Notes and Chassis Compatibility

The collars are manufactured to match MP9 steering geometry and install cleanly on factory knuckle assemblies. They secure the knuckle arms without adding play, making them suitable for racers who need dependable steering alignment on asphalt or carpet circuits.

Workshop Tips for Best Results

Before fitting the Kyosho IF420B collars, clean mating surfaces and inspect for wear. Install the collars straight, torque fasteners evenly, and recheck after a few runs. Routine inspections will spot looseness or wear early and keep steering feeling crisp.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will these collars work on MP9 upgrade knuckles?

They are designed for MP9 style knuckles; many aftermarket MP9-compatible knuckles will accept the same collars but check diameter and shoulder fit before installing.

How can I tell when to replace the collars?

Inspect for visible wear, scoring or excess play in the steering. Replace if the collars no longer hold the knuckle tight or if parts show deformation.

Any setup tips for race day?

Check collar tightness after your warmup runs, keep the steering bearings clean, and avoid over-tightening which can bind the steering. Small adjustments to toe and caster will reveal the collars impact quickly.
