WR037SA Adjustable Main Shaft Upgrade for AXIAL WRAITH by GPM  [WR037SA]

WR037SA Tunable Main Shaft for AXIAL WRAITH

This WR037SA main shaft assembly is engineered for precision axle tuning on AXIAL WRAITH platforms, combining a 6061-T6 aluminum shaft body with hardened #45 steel universal swing shafts in a cross head configuration. The mixed-material layout reduces rotating mass while maintaining hardened contact surfaces where load and wear are concentrated.

The adjustable mechanism provides a 126mm to 135mm span for fine wheelbase calibration to suit specific crawling geometries. Hardened swing shafts protect pivot and cross head areas from accelerated wear, while the alloy body lowers rotational inertia to improve dynamic axle response during articulation.

Included hardware mirrors original small parts such as white silicone O-rings and mounting screws to secure the shaft into standard WRAITH housings. Professional assembly practice is recommended: verify axial alignment, confirm full suspension and steering clearance, and torque fasteners to thread specifications before operational use.

Use the WR037SA when you require a precisely adjustable alloy shaft body with hardened swing components to tune wheelbase and improve articulated steering behaviour on AXIAL WRAITH crawlers.
