Refine Handling with the Kyosho XGS021 Big Bore Spring

The Kyosho XGS021 Big Bore Shock Spring is made for ULTIMA Series SC6 cars and supplies a medium-hard spring rate to tighten turn-in and improve rebound stability. Its red finish is practical for quick identification when making setup changes between sessions.

Setup Compatibility and Effects

Ideal for drivers who experiment with spring rates, this component lets you tune roll stiffness and pitch behaviour without replacing shock bodies. It installs into compatible big bore shocks used on ULTIMA SC6 platforms with minimal fuss.

Main Benefits

  • Material: Tough steel construction for consistent service life.
  • Color: Red coating for easy visual checks in the pits.
  • Tension: Medium-hard rate that moderates body roll while keeping traction.
  • Compatibility: Specifically produced to match ULTIMA Series SC6 shock geometry.
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 retrofitted shocks?

It will fit where spring seat diameter and length match ULTIMA SC6 specifications; confirm dimensions if your shocks have aftermarket modifications.

Does spring rate affect tyre contact?

Yes, a firmer spring can help maintain tyre contact under corner loads, but it may reduce compliance on rough surfaces so tune according to the circuit.

How often should I inspect springs?

Inspect springs regularly after heavy running or if handling changes; check free length and look for corrosion to avoid inconsistent performance.
