King Pin Tuning: Overview and purpose

The Kyosho SCW041 Handling Adjust King Pin Set supplies a pair of reduced-diameter kingpins intended for Tomahawk 85WC assemblies and listed as an optional item for Scorpion-series chassis. The set intentionally shifts the kingpin outer diameter below the standard 4.0mm range to introduce controlled pivot clearance, letting you refine steering behavior on slick surfaces without major layout changes.

This kit contains two stepped sizes, 3.9mm and 3.8mm, so you can make incremental changes. Moving to a smaller outer diameter increases lateral clearance at the steering pivot, which can calm quick steering reactions and aid stability down straights while retaining usable cornering response for fine tuning.

Installation notes: the parts are designed as direct replacements for standard kingpins on compatible Tomahawk 85WC assemblies and may be fitted to Scorpion-series units that share the same pivot interfaces. Expect only small steering geometry shifts; no drilling or chassis modification should be necessary when the part fits. As with any tuning change, adjust gradually and test progressively.
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.

Which kingpin sizes are supplied in the SCW041 kit?

The kit provides two reduced outer diameters: 3.9mm and 3.8mm. Use the larger step first, then try 3.8mm if you need more pivot clearance.

How does a smaller kingpin diameter affect steering feel?

A smaller diameter increases side clearance at the pivot, which can reduce twitch and help the chassis track straighter on low-traction surfaces while slightly softening initial steering bite.

Can I fit these to other Kyosho models?

They are specified for Tomahawk 85WC and noted as optional for Scorpion-series chassis. Check pivot dimensions on other models before installing to ensure correct fitment.
