Tamiya FF-03 Differential Ring by 3Racing FF03-05/LB  [FF03-05/LB]

Differential ring for FF-03 chassis

This is an RC-scale differential ring intended for use with the Tamiya FF-03 chassis, supplied as 3Racing part FF03-05/LB. It serves as a replacement ring gear inside the model differential and is intended for routine maintenance, repair, or parts refresh when the original ring shows wear.

Installation involves standard differential disassembly, inspection of the mating pinion and bearings, and careful reassembly to restore correct gear mesh. Check the ring teeth for wear or burrs and confirm smooth rotation before finalizing reassembly. Use appropriate differential grease compatible with plastic or metal gears as required by your existing differential components.

In tuning and upkeep, a correctly fitted ring gear helps maintain consistent gear engagement and drivetrain smoothness. Replacing a worn ring is a basic step for restoring proper operation and can be part of regular service intervals for track or club use.
