TAMIYA M1025 Hummer 43mm Steel CVD Front/Rear Shaft HM1243C by GPM  [HM1243C]

Front and rear steel CVD shaft

This steel front and rear CVD shaft is intended for the TAMIYA M1025 Hummer platform and is supplied as 1pr for RC-scale driveline use. It is a direct-replacement driveshaft option to substitute common plastic originals when a metal component is required for extended service life in hobby running.

Specified as 43mm and steel, the shaft transmits rotation from gearbox outputs to wheel hubs in either front or rear placements on the M1025 chassis. During fitting inspect the drive cups, hexes and bearings for proper mating and alignment, and confirm the shaft turns freely without binding to prevent premature wear.

For upkeep treat the shaft as a straightforward upgrade: check splines and runout periodically, lubricate spline interfaces lightly with recommended RC grease, and change the shaft if spline fitment or straightness degrades. The upgrade is focused on drivetrain durability rather than vehicle speed or torque gains.
