This Kyosho LA402-03 diff bevel shaft is an RC-scale replacement part provided as two pieces for fitting into the LAZER ZX7.5 differential assembly. It helps recover correct bevel gear engagement inside the diff so torque transfer remains consistent and gear meshing stays uniform after component wear.
Practical notes for hobby use: clean bearing seats and bevel faces before installation, confirm diff housing clearance during fitment, and observe gear mesh when tuning for smoother driveline operation. Proper shaft alignment can influence traction feel and drivetrain refinement on 1/10-scale rigs.
