This Kyosho LA402-03 diff bevel shaft is an RC-scale replacement component supplied as two pcs for the LAZER ZX7.5 differential assembly. It is intended to restore or maintain proper bevel gear engagement inside the model differential, helping preserve torque transfer characteristics and consistent gear meshing after wear or damage.
Practical notes for hobby use: inspect associated ball bearings and bevel gears when replacing the shaft, keep mating surfaces clean, and confirm the diff housing clearance before final assembly. The shaft plays a tuning role by ensuring stable bevel gear alignment, which can affect driveline smoothness and traction response in 1/10-scale setups.
