Fine Tune Steering with the Kyosho VZ423

The Kyosho VZ423 Servo Saver Spring is a purpose made replacement for the V ONE R4 to improve steering accuracy. Its consistent spring rate helps maintain repeatable steering inputs during race and practice sessions.

Specifically for the V ONE R4

Manufactured to suit the V ONE R4 servo saver, the VZ423 delivers stable centring force and resists premature wear. That stability makes setup adjustments more predictable and saves time on the pit bench.

Recommended for Regular Racers

For drivers who race frequently, fitting the Kyosho VZ423 helps keep steering play under control and reduces the chance of inconsistent handling between heats.
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 VZ423 suit high-torque servos?

Yes. The spring is compatible with typical high-torque servos used in touring setups, though correct servo saver adjustment is still important.

Will changing to this spring affect steering speed?

The VZ423 influences centring and feel rather than the servo speed itself, so steering response feels crisper without changing servo actuation speed.

Any tips for fitting the spring?

Make sure the spring sits evenly in the saver cup and check for smooth free movement of the servo saver after installation. Test on the bench before track use.
