Tamiya FF-03 Machined Ball Differential - FF03-01 by 3Racing  [FF03-01]

Machined ball differential for FF-03 chassis

This machined aluminium ball differential is an aftermarket replacement crafted for the Tamiya FF-03 platform, intended to swap out the standard plastic internals for improved longevity and more repeatable tuning adjustments via preload and ball selection.

Compatibility guidance: designed to meet FF-03 gearbox layout and mounting details, the unit follows conventional ball differential geometry and aligns with FF-03 spec carriers. Confirm part references and carrier fittings when mixing with other drivetrain components.

Installation and setup advice: install into the existing FF-03 differential carrier and set preload to tune on-power behaviour; try multiple ball sizes to refine corner grip and throttle stability. Keep lubrication limited to diff grease suited for ball differentials and inspect balls and races as part of routine maintenance.

Maintenance guidance: clean aluminium parts with cleaners safe for anodised or machined surfaces and check contact faces and drive cups for wear. Replace worn balls or races to maintain consistent performance. This product is for hobby chassis servicing and setup work only.

Choose this machined ball differential to bring a robust, tuneable drivetrain element to an FF-03 touring car and improve mechanical feel under load.
