TRX4M Front and Rear Centre Driveshafts Precision Upgrade TRX4M037S by GPM  [TRX4M037S]

Front and rear center driveshafts

This aftermarket set provides front and rear center driveshafts made for 1/18 scale TRX4M platforms, supplied as RC-scale replacement parts rather than factory originals. Constructed from medium carbon steel as noted in the product name, the shafts are intended to handle higher torque loads and accommodate larger transmission angles commonly encountered on scaled 4WD crawler and trail rigs.

Fitment and role: these driveshafts transfer motor output through the center of the chassis to front and rear differentials, so they play a direct role in drivetrain strength, responsiveness, and durability during high articulation or heavier setup runs. Use them when upgrading load capacity or when the stock shafts reach their limits in extended-throw suspensions.

Installation notes: the set includes the small screw pins needed for mounting; standard disassembly of the transfer/center output area is required and basic hand tools such as hex drivers are sufficient. Confirm spline and coupling fit on your TRX4M transfer case before final torqueing to avoid binding at extreme articulation angles.

For builders focused on drivetrain robustness or swapping in stronger center components on TRX4M 1/18 4WD platforms, this set offers a medium carbon steel alternative that balances strength and fitment for common upgrades and repairs.
