Refined Spring Upgrade for 1/10 Scale RCs

The Kyosho IFS003-915 Big Shock Spring is made to refine suspension tuning on compatible RC cars. At 85mm length with a 9-1.5 spring rate and blue finish, it gives predictable behaviour for different track conditions.

Improved stability and response

The spring helps sharpen steering feedback and control when pushing through corners, particularly on uneven layouts. Robust construction aims for long service life under regular use.

Simple fitting and checks

Its dimensions suit many 1/10 scale models, and fitting is straightforward with standard shock tools. Always measure shock overall length and travel before swapping springs to verify fit.
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.

What does a 9-1.5 rating mean for my setup?

The 9-1.5 figure indicates coil stiffness and pitch; it gives a balanced feel between firmness and compliance suitable for mixed surfaces.

Should I change spring preload?

Adjust preload to fine tune ride height and initial spring compression, but avoid excessive preload that reduces travel and increases binding.

When is a spring worn out?

Replace springs that have lost shape, show coil separation, or cause noticeable handling changes compared to new parts.

Can I combine these with different oils?

Yes, mixing spring rates and oil viscosities is a standard way to dial damping and ride characteristics to suit track and driving style.
