Setup-Oriented 33.5mm Swing Shaft for Cero M

The 3Racing SAK-CM112A swing shaft is specified to 33.5mm for the Cero M chassis to preserve steering geometry under race loads. Intended for competitive applications, this shaft supports consistent steering feedback that aids setup and tuning adjustments.

How does shaft length affect steering behaviour

Shaft length determines lever arm and linkage positions; the 33.5mm dimension keeps the Cero M geometry within spec, helping maintain predictable roll steer and turn-in characteristics.

What should I inspect when swapping this part

Check mating bearings, ball studs and linkage play. Replace any worn components to ensure the new shaft translates inputs precisely during tuning sessions.

Is this suitable for tight setup changes between heats

Yes, swapping to a correctly sized shaft like the SAK-CM112A helps restore baseline steering geometry quickly, making it easier to iterate small setup changes between runs.
