This aftermarket steel main drive shaft fits the Tractor Truck (1838ls) platform and is supplied as 1 pcs under the identifier TRU130S. The 130mm length and steel material make it a straightforward option for models requiring a robust replacement shaft.
Functionally the shaft replaces worn drivetrain parts and helps maintain correct gear alignment and rotational stability inside the transmission. Confirm that the 130mm measurement and coupling interface match your TAMIYA chassis before fitting the part.
Fitment advice: inspect spline faces and contact points for damage, seat the shaft securely in the gearbox or coupling, and check for axial free play once assembled. Choose this steel shaft where added stiffness and service life are priorities during regular maintenance or setup changes.
