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

Durable steel CVD shaft for M1025

This aftermarket steel front and rear CVD shaft is specified for the TAMIYA M1025 Hummer platform and supplied as 1pr for RC-scale driveline use. It serves as a direct replacement for common plastic driveshafts where a metal option is wanted to increase service life under routine model use.

Described as 43mm and steel, the shaft transfers torque between gearbox outputs and wheel hubs in front or rear positions on the M1025 chassis. When assembling check the fit at drive cups, verify hex and bearing condition, and ensure proper alignment so the shaft rotates smoothly and avoids premature wear.

For maintenance consider this a reliability upgrade: inspect splines and straightness regularly, keep spline interfaces lightly lubricated with suitable RC grease, and replace the shaft if spline engagement or straightness deteriorates. The part improves driveline durability without altering engine or motor performance figures.
