This steel main drive shaft is intended for the Tractor Truck (1838ls) RC chassis and is supplied as 1 pcs under the TRU130S reference. The 130mm length and steel construction make it a reliable aftermarket replacement for compatible TAMIYA transmissions.
The shaft is used to replace worn or damaged drivetrain components and to maintain correct gear alignment and smooth rotational behaviour inside the gearbox. Confirm the 130mm length and coupling interface on your model before fitting to avoid mismatch issues.
Assembly guidance: inspect mating faces and splines for damage, ensure proper seating in the gearbox or coupling, and check for axial play after installation. Choose this steel option where increased stiffness and longer wear life are required for regular running or tuning work.
