The Kyosho VZW066-20B is a 20-tooth, 0.8M steel first gear produced for the V ONE R4 series. Its exact tooth cutting and durable steel body preserve efficient drive transfer and help keep adjacent gears in good condition during normal use.
With a robust steel construction, the VZW066-20B offers longer service life compared to softer materials and sustains precise engagement under load. This helps reduce irregular wear and keeps drivetrain performance predictable.
Engineered for direct fit to V ONE R4 gearboxes, this part installs using the original mounting arrangement. It is a straightforward replacement for maintenance cycles or for restoring gearbox integrity after heavy running.
