Refine Handling with Kyosho XGS004 Shock Spring

The Kyosho XGS004 Medium Hard Big Bore Shock Spring helps sharpen handling and stabilise body roll for more precise driving. It is aimed at hobbyists who prioritise predictable suspension behavior on circuit and club tracks.

Purpose Built for Big Bore Systems

This medium hard spring is tuned for big bore dampers to deliver a consistent feel under braking and cornering. Its construction supports steady rebound and compression characteristics for repeatable lap times.

Fitment Notes and Tuning Tips

The XGS004 fits a broad range of big bore shocks and can be used to alter platform balance quickly. Try small changes to preload and damping to find the best combo for your setup and surface.
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.

Can I mix this spring front and rear?

You can run XGS004 front and/or rear to bias handling; mixing different rates front to rear is a common way to tune oversteer and understeer.

What maintenance keeps springs working well?

Keep springs clean and inspect for bends or fatigue; replace if coils show uneven wear to maintain consistent suspension response.

Should I change shock oil with the spring swap?

It is a good idea to review your oil choice when changing spring rates since damping and spring rate work together to control body movement.

Are there upgrades that pair well with this spring?

Consider stronger shock shafts, upgraded pistons, or adjustable collars to fully exploit the XGS004 and refine suspension tuning.

How do I evaluate spring performance on track?

Run lap tests and note handling changes such as roll, traction and braking feel; make incremental adjustments to find the most balanced setup.
