This steel main drive shaft is supplied as 1 pcs for the Tractor Truck (1838ls) platform and identified as TRU130S. At 130mm overall length the shaft provides a direct aftermarket option for compatible TAMIYA chassis that require a durable replacement.
In everyday use the shaft restores drivetrain stability and corrects gear alignment inside the transmission region. Proper fit depends on the mounting points and coupling design on your model, so check the 130mm length and interface before you install the new shaft.
Fitting notes: examine splines and mating surfaces for signs of wear, ensure full seating in the gearbox or coupling, and verify there is minimal axial play after assembly. Opt for this steel component when you need extra stiffness or longer service intervals during regular maintenance.
