Dedicated rear shock stay for Tomahawk chassis

The SCW039 rear shock stay is a CNC-machined 3mm black FRP plate intended as an optional top mount for Tomahawk-style Scorpion-series chassis. It delivers a stable, repeatable anchor for the upper ends of rear shocks, suited to modelers focused on precise setup adjustments and consistent handling.

For correct installation this stay must be paired with the SCW040 Adjustable Shocks; it is not compatible with the SCW013 HG Shock Set and must not be used with that set. The part is supplied as a single FRP plate machined with mounting holes and alignment points; most builders use the standard shock hardware and mounting screws from the original kit for fitment.

Replacing the factory shock top mount with a machined FRP stay increases top mount rigidity and changes how piston travel corresponds to chassis movement. Competitors and hobbyists fit this piece to lock in top mount alignment and keep shock positions repeatable while exploring spring and damper changes.

Compatibility

  • Intended for Scorpion-series Tomahawk chassis when used with SCW040 Adjustable Shocks
  • Not compatible with SCW013 HG Shock Set
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.

How does swapping to this stay change setup strategy?

Using a stiffer FRP top mount alters shock leverage and can reduce variability between runs; treat the stay as a baseline change and retune springs and damping to regain the desired balance.

Are there any fitment checks before bolting it on?

Yes. Confirm the machined hole pattern aligns with your Tomahawk Scorpion-series chassis and ensure SCW040 Adjustable Shocks match the intended top mount spacing before final assembly.

What maintenance does the FRP plate need?

FRP requires minimal upkeep; periodically inspect mounting holes for wear, check screws for correct torque, and replace any damaged hardware to preserve alignment and performance.
