The Kyosho VZW066-20B is a replacement 0.8M 20-tooth steel first gear intended for the V ONE R4 series. Precision-cut teeth and solid steel build allow consistent power flow to downstream gears, useful for regular servicing or refreshing a gearbox after heavy use.
Manufactured from high-grade steel, the VZW066-20B resists deformation and maintains gear mesh under stress. The accurate tooth profile supports even loading across the gearset which helps reduce premature wear on related components.
Matched to the V ONE R4 drivetrain, this gear installs without custom work and lines up with standard components. It is a convenient spare for trackside swaps or scheduled maintenance intervals.
