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

Replacement ring gear for FF-03

This aftermarket differential ring fits the Tamiya FF-03 chassis and is listed as part FF03-05/LB. It is intended to replace a worn internal ring gear to restore the differential to correct operating condition during regular servicing or repairs.

Procedure for fitment is standard: open the differential, inspect the mating pinion and bearings, and reposition components to achieve proper gear contact. Remove any damaged teeth or debris, verify the ring rotates smoothly, and apply suitable grease compatible with your diff components before reassembly.

A good ring gear installation maintains steady tooth engagement and helps the drivetrain run smoothly under load. Routine replacement of worn parts is an effective way to keep handling predictable for club or local track use.
