Carbon Strengthened Gear Case for FF03 Drivetrains

The Tamiya 54398 gear case is a straightforward upgrade for modellers aiming to stiffen the FF03 platform. Made to house a gear differential unit, the carbon reinforced construction improves rigidity and helps maintain gear alignment under load. It fits the FF-03 and FF-03R chassis, making it suitable for fine tuning drivetrain performance.

Compatible Gear Differential Components

To ensure reliable differential behaviour, fit the Tamiya 54398 alongside these recommended components:

Item 51460 TA06 Gear Differential Unit Bevel Gear Set
Item 51462 TA06 Rear Gear Differential Case Set (52T)
Item 51464 TA06 Gear Differential Unit Gasket (4pcs.)
Item 51466 TA06 Gear Differential Unit Cup Joint Set

Is any chassis trimming required for fitment?

No trimming is typically required. The Tamiya 54398 is designed to drop into FF-03 and FF-03R layouts as a direct replacement for the standard case.

Which differential parts should I replace when upgrading?

Inspect bevel gears, gaskets and cup joints and replace any items that show wear. Using fresh gaskets helps prevent oil seepage and keeps the diff sealed.

Will this case suit both track and casual use?

Yes. The added rigidity benefits precise track setups but also improves durability for regular club running and practice sessions.

Any advice for setting gear mesh after install?

Set a light, even gear mesh with a small amount of play to avoid binding. Rotate the drivetrain after assembly to confirm smooth, quiet operation before final tightening.
