Dial in Exact Steering with Kyosho IF420B Collars

The Kyosho IF420B knuckle arm collars are a compact upgrade that helps preserve steering geometry on MP9 chassis. They reduce unwanted movement at the knuckle pivot so steering remains predictable under load.

Compatibility and Practical Use

These collars are produced to mate with MP9 knuckles and steering shafts, allowing a clean install with stock or many aftermarket components. They help keep alignment stable during hard braking and cornering.

Fitting Pointers for Reliable Operation

Ensure mating surfaces are free from oil and debris before fitting the Kyosho IF420B collars. Tighten evenly and recheck after your first few laps. Periodic checks will prevent slack and extend part life.
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 change my steering geometry?

They are designed to secure existing geometry rather than alter it. Proper installation maintains the factory steering setup while reducing play.

Are they compatible with aluminium knuckles?

Many MP9-compatible aluminium knuckles use the same collar interface, but confirm shaft and bore dimensions to ensure a correct fit.

How often should I check them?

Check collar tightness and condition as part of your routine pre-run inspection, and after impacts or long sessions to avoid developing steering play.
