Technical overview of the rear main shaft

This precision replacement rear main drive shaft is engineered for Axial Yeti drivetrains, using hardened steel connection points mated to a 6061-T aluminum shaft body to reduce rotating inertia while maintaining required torsional stiffness.

The assembly employs a retained steel wire ring to secure set screws and prevent fastener loosening under vibratory loads. The aluminum sleeve reduces mass at the shaft midspan while keeping stiffness where load transfer occurs. Adjustable length covers 147mm to 157mm to permit accurate driveline engagement and reproducible pinion/spur mesh adjustments.

For correct installation verify chassis clearance for the chosen length setting and torque the set screws to the recommended values for M4 size hardware. The unit ships with two 2.5XM4X11 stainless steel screws for secure mounting to the driveline junction.

Specifications

  • Item: Axial Yeti rear main drive shaft, 1pc set
  • Material: Steel and 6061-T aluminum
  • Model Number: GPM YT237SA
  • Length Adjustable: 147mm–157mm
  • Included Hardware: 2.5XM4X11 stainless steel screws, 2 pcs

A precision upgrade option for Yeti drivetrains where controlled rotating mass and reliable screw retention are priorities.

What inspection points should I use after installation?

Check set screw torque, verify the wire ring is seated correctly, and confirm shaft runout and driveline alignment under static rotation before field use.

Are there recommended torque values for the set screws?

Follow the vehicle maker's recommended torque for M4-size fasteners; avoid overtorque which can deform the aluminium sleeve or strip threads.

How does the aluminium shaft affect dynamic balance?

Lower rotating mass at the shaft midspan reduces inertia and can improve transient driveline response, but proper alignment and secure fasteners are required to realise performance benefits.
