Overview of the rear main shaft

This replacement rear main drive shaft is intended for Axial Yeti drivetrain installations, pairing hardened steel terminations with a 6061-T aluminium shaft tube to balance strength and reduced rotating inertia.

The design includes a steel wire retention ring that secures the set screws and helps prevent fastener loosening under vibration. The aluminium sleeve cuts weight while maintaining the necessary stiffness for driveline stability. Length adjusts from 147mm to 157mm so you can dial in driveline engagement and correct pinion/spur mesh without sourcing a different shaft.

Confirm the adjustable range fits your Yeti chassis clearance and fasten the set screws to the torque values recommended by the vehicle maker. The package contains two 2.5XM4X11 stainless steel screws for mounting the assembly.

How precise is the length adjustment?

Adjustment spans 147mm to 157mm, allowing fine trimming in millimetre steps depending on how you set and lock the screws.

Is the shaft corrosion resistant?

The supplied stainless steel screws resist corrosion; the shaft materials are common for RC parts but regular inspection and cleaning will extend service life.

Can I use this with modified gearboxes?

It works with standard Yeti gearbox outputs that accept a 147-157mm adjustable shaft; verify mounting fit and alignment if your gearbox has nonstandard adapters.

What maintenance is required?

Periodically inspect the wire ring and set screws for tightness and wear, and clean debris from the sleeve to prevent binding.
