Optimise V ONE R4 Clutch Performance with Kyosho VZ438

The Kyosho VZ438 1.7mm clutch spring is produced for the V ONE R4 series as a direct replacement and tuning option. It brings a predictable engagement point that helps maintain consistent driveability in both practice and race settings.

Built for Consistency

The spring offers even tension across cycles to reduce slip and improve control during acceleration. Its durable construction suits those who demand repeatable performance over many runs.

Fitting and Maintenance

When installing the Kyosho VZ438, make sure the clutch area is clean and that the spring seats correctly. Inspect after heavy sessions and replace if you detect reduced tension or distortion.
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.

Does the VZ438 suit different driving styles?

Yes. The VZ438 works well for cautious commuting runs as well as aggressive track driving, though competition use will require more frequent checks.

How do I store spare springs correctly?

Keep spares in a dry, dust-free container and avoid compressing them against hard surfaces. Proper storage helps avoid bends or loss of spring tension.

Can changing spring rate require other setup changes?

Adjusting spring stiffness may mean tuning shoe type, slipper settings or throttle trim to achieve the desired driveability. Test changes incrementally to find the right balance.

Is professional fitting recommended?

Most hobbyists can fit the spring themselves, but if you are unsure about clutch timing or seating, a tech or experienced teammate can help avoid setup mistakes.

What signs indicate fatigue besides visible wear?

Feel for inconsistent engagement, slipping under load, or a change in engagement point between runs. Any of these suggest it is time to replace the spring.
