Upgrade spring for kingpin-style suspension

The Yokomo YOKYF14SH hard spring is an RC-scale replacement crafted to fit the YRF001 kingpin suspension arrangement. It is intended as a tuning part to increase spring rate without altering shock bodies or pistons.

Installation notes: compress the spring onto the shock shaft to replace the existing unit, confirm correct seating on the perch, and check preload and travel clearance before operating. Fit matching springs on each side to retain balance, and pair the change with shock oil or piston tweaks if more refined control is needed.

Tuning impact: choosing this higher-rate spring lowers body roll and improves steering precision under medium to high cornering loads, ideal for higher-grip tracks or when stiffening the chassis is necessary. Observe tyre wear and steering feedback and adjust other settings to suit.
Remark :
Due to limited stock availability, please notice that some Yokomo 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 fit the YOKYF14SH straight onto YRF001 kingpin shocks?

Yes, the spring is produced as a direct replacement for YRF001 kingpin suspension springs and should fit without alteration.

Any setup advice after switching to a harder spring?

After fitting, reassess shock oil grade and piston selection, as well as anti-roll bar settings, to balance the stiffer spring and achieve the desired handling.

What are the key on-track benefits?

You will generally gain reduced body roll and more responsive steering at higher cornering loads, which improves turn-in and mid-corner stability on grippy surfaces.
