Technical overview

The TRU130S is a 130mm steel main drive shaft supplied as 1 pcs for the Tractor Truck (1838ls) platform. Designed for direct aftermarket replacement where the stated length and spline interface match, this steel shaft aims to restore drivetrain alignment and rotational stability within the gearbox assembly.

Use the TRU130S to replace worn components and maintain consistent gear meshing under load. Confirm mounting points, coupling geometry and spline compatibility before installation to ensure correct fit and secure seating in the transmission housing.

Workshop notes: inspect splines and bearing surfaces for wear, seat the shaft fully in the gearbox or coupling, and verify axial play after assembly. Select the steel TRU130S when increased stiffness and long term wear resistance are required during tuning or regular maintenance regimes.

What inspection steps should be taken prior to fitment?

Check spline integrity, measure overall shaft length against the TRU130S 130mm specification, and confirm coupling alignment and gearbox seating locations to avoid tolerance issues.

How does material choice affect performance?

Steel provides improved wear resistance and stiffness compared with some stock materials, which helps maintain gear alignment under higher torque, but verify adjacent components are compatible with the increased loads.

What post fit checks are recommended?

After assembly, run the drivetrain by hand to confirm smooth rotation, then test at low speed verifying there is no binding or excessive axial movement.
