Tamiya FF-03 Rear Axle Replacement FF03-17 by 3Racing  [FF03-17]

FF-03 rear axle kit

This 3Racing FF03-17 rear axle set is supplied as an RC-scale replacement for Tamiya FF-03 chassis, intended as a hop-up item to assist drivetrain maintenance and setup tuning. It fits as a direct replacement to restore rear driveline function or to be used when switching parts during setup work.

Fitting requires standard FF-03 knowledge: remove the rear driveline from the chassis, replace the axle assembly, check seating in gearbox and suspension mounts, and verify smooth, free rotation. Use care with small fasteners and bearings and confirm all fasteners are secure after reassembly.

In tuning scenarios, axle swaps will influence endplay and gear engagement, which affects drivetrain smoothness. After installation inspect for lateral play, make sure spur and pinion mesh correctly, and run a short test to ensure no unexpected wear appears.
