TB-04 Bevel Gear Set, RC chassis spare parts

This TB-04 bevel gear set brings carbon fiber-reinforced resin construction to a key drivetrain area, giving TB-04 chassis cars gears that are more resistant to wear and suited to use with higher-powered motors. The set is made up of 3 matched transmission parts that work together where rotational force changes direction inside the chassis. A 40T ring gear handles the larger driven stage, while the 16T bevel gear and 20T miter gear complete the meshing set for the TB-04 layout. The angled teeth on these gears are designed to engage under load as the drivetrain transfers power through the chassis, making correct fit and matched tooth contact especially important. Because the parts are specified as a set, installation as a complete group helps maintain the intended relationship between the gears rather than mixing single replacements into an existing worn setup. This spare parts set suits maintenance, repair and drivetrain refresh work on compatible TB-04 chassis cars. It fits naturally into workshop sessions focused on restoring clean gear action after running with stronger motor setups or replacing worn internal transmission parts with the correct matched components.
