Tune Suspension Response with the Kyosho XGS021 Red Big Bore Spring

The Kyosho XGS021 Big Bore Shock Spring fits ULTIMA Series SC6 cars and provides medium-hard spring rate for balanced handling across mixed surfaces. Its red finish gives a clean race look while helping stabilise chassis movement during cornering and landings.

Fitment and Ride Behavior

Made for hobbyists who adjust their setups, this spring allows incremental changes to damping feel and weight transfer. It installs into standard big bore shock assemblies used on ULTIMA SC6 models and works well when swapping springs to suit track grip.

Key Attributes of the Big Bore Spring

  • Material: Hardened steel construction for dependable service life.
  • Color: Bright red finish for easy visual ID at the pits.
  • Tension: Medium-hard rate that balances roll control with traction.
  • Compatibility: Specifically sized for ULTIMA Series SC6 shock assemblies.
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 the spring fit other big bore shocks?

It is made for ULTIMA SC6 big bore shocks, but you may be able to use it on other models with the same shock internal diameter and seat geometry. Check measurements before fitting.

How does medium-hard tension change handling?

Medium-hard springs reduce excessive body roll while retaining enough compliance for traction, making them a good all-round choice for mixed grip tracks.

What maintenance keeps springs performing?

Wipe down springs to remove grit, inspect for corrosion or sag, and replace if coils show wear to maintain consistent suspension feel.
