Fine-tune FANTOM suspension with Kyosho EF243 front springs

The Kyosho EF243 front springs are a straightforward upgrade for FANTOM owners who want to adjust suspension response. This four-piece medium-rate set is made for the Legendary Series FANTOM and helps deliver steadier handling across mixed surfaces.

Track and Road Compatibility

These front springs are aimed at hobbyists who swap setups between street and track sessions. Swapping in the EF243 springs softens and firms the front end in balance, yielding more predictable steering and improved cornering feel without radical changes to ride height.

Simple Fitment Steps

Fitting the Kyosho EF243 front springs is simple and requires basic tools. Remove the old springs from the shock assemblies, seat the EF243 springs correctly, and verify all retainers and caps are secure before running the car.
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 these springs change my FANTOM's ride height?

The EF243 are medium-rate springs so ride height change should be minimal; most users notice handling improvements rather than a large lift or drop.

Are any special shock oils required when fitting these springs?

You can use your current shock oil grades; the EF243 springs do not require a specific oil but matching oil to spring rate will optimise damping performance.

Can I use these springs on a tuned FANTOM with upgraded shocks?

Yes, the EF243 work well with upgraded shocks, but verify spring preload and shock travel to avoid binding at full droop or compression.
