TRF421/420/419 Spur Gear 116T M0.4, spare part

The TRF421/420/419 Spur Gear 116T M0.4 is a dedicated spare part for compatible Tamiya racing chassis, built around a 116-tooth layout and module 0.4 specification. That combination makes it a direct drivetrain replacement when the original gear shows wear, helping restore the intended transmission setup for continued running and regular workshop service. Its role sits at the center of the drivetrain, where tooth count and module need to match the chassis design exactly. The pack contains 1 spur gear, so maintenance can stay focused on the specific part that needs replacement rather than a larger mixed set. The source data also names compatibility with the TRF418 chassis in the long text, while the short designation states TRF421/420/419; this copy therefore follows the current product designation without extending fitment beyond the provided naming. As a model accessory in the Models Supplies category, it suits bench stock for rebuilds, wear replacement and planned servicing. During routine maintenance, a fresh spur gear can be fitted when drivetrain wear becomes visible or when a rebuild calls for the stated 116T M0.4 specification. Kept in a parts case or workshop drawer, it gives compatible chassis a like-for-like replacement ready for the next service interval.
