Axial Yeti Rear Main Drive Shaft Adjustable 147-157mm YT237SA by GPM  [YT237SA]

Adjustable rear main shaft summary

This replacement rear main drive shaft is made for Axial Yeti drivetrains and pairs hardened steel fittings with a 6061-T aluminum shaft body to reduce rotating mass while keeping strength in the critical sections. The design serves as a tunable link between gearbox outputs and the rear differential for improved driveline setup.

The assembly uses a retained steel wire ring to lock the set screws in place so fasteners resist loosening under vibration. The aluminium sleeve lowers weight but keeps lateral stiffness where required. Adjustable length covers 147mm to 157mm to allow precise driveline engagement and pinion to spur alignment without swapping shafts.

Before installation confirm the adjustable length suits your Yeti chassis clearance and tighten the set screws to the vehicle maker's torque recommendation for hardware this size. The part ships with two 2.5XM4X11 stainless steel screws to secure the shaft to the driveline junction.

A straightforward replacement and tuning option for Axial Yeti drivetrains when a light adjustable shaft and secure fastener retention are needed.
