The LOS212020 Top Shaft is a genuine Losi drivetrain component designed for the Mini-T platform. It is a key transmission shaft that works inside the gearbox to transfer power from the motor or primary gear set to the rest of the drivetrain.
This shaft supports the spur gear and related transmission gears, helping maintain smooth rotation and proper gear mesh under load. Because it is part of the main power transfer system, it must stay straight and properly supported to avoid vibration, gear skipping, or loss of efficiency.
It is commonly replaced during transmission rebuilds or when wear, bending, or bearing damage affects smooth drivetrain operation.
