Precision Front and Rear Main Shafts for R1

This two-piece adjustable main drive shaft assembly is engineered for the GMADE R1 Rock Buggy, combining 6061-T6 aluminium shaft bodies with steel hardware to achieve a favourable strength-to-mass ratio for RC drivetrain applications.

The aluminium shaft sections reduce rotating inertia relative to all-steel designs, improving electrical efficiency in electric vehicles while maintaining alignment precision in the driveline. Steel wire rings secure the retaining screws to prevent hardware loss in aggressive terrain.

Shaft length is adjustable to fit common chassis spacings: front 122mm-132mm and rear 105mm-115mm. The kit includes the necessary O-rings and Screws for direct installation, reducing the need for additional consumables.

Packing includes

  • Screw Shaft 2.3XM4X11 - 4pcs
  • Oring 4X2.5 - 4pcs
  • Oring 4X1.5 - 4pcs

Intended as a precision aftermarket drivetrain component where reduced rotating mass and adjustable length are required; follow standard torque and inspection routines to ensure long service life.

What torque is recommended for the M4 screws?

Use a controlled, low torque setting appropriate for M4 fasteners in aluminium (typically light threadlock and hand torque to avoid stripping), then secure the steel wire ring to retain the screw.

How does aluminium affect drivetrain wear?

Aluminium reduces rotating mass but still transmits torque effectively; inspect mating surfaces and O-rings periodically for wear and replace consumables as needed.

Are the wire rings reusable after removal?

They can be reused if undamaged and retaining shape; replace any ring that shows distortion to maintain secure screw retention.

Recommended inspection intervals?

Inspect fasteners, wire rings, and O-rings after intense runs or monthly for moderate use; address any play or wear before further operation.
