GPM TAMIYA M1025 Hummer 43mm Steel Front/Rear CVD Shaft HM1243C - RC Spare Part  [HM1243C]

Steel CVD driveshaft for TAMIYA M1025

This steel front and rear CVD shaft is made for the TAMIYA M1025 Hummer platform and is supplied as a 1pr for RC-scale driveline applications. The part is a direct-replacement driveshaft intended to swap in for common plastic originals when a metal option is preferred for longer service life under everyday RC use.

The component is described as 43mm and steel, and it transmits rotational drive between gearbox output and the wheel hubs in either the front or rear locations on the M1025 chassis. During assembly check the mating fit at the drive cups and inspect the hexes and bearings before final installation. Confirm smooth rotation and correct alignment to prevent early wear.

For routine tuning and maintenance treat the shaft as a durability upgrade: inspect splines and straightness periodically, apply light spline lubrication using appropriate RC grease, and replace the shaft if spline engagement or straightness deteriorates. This part improves drivetrain robustness rather than changing power or speed figures.
