Tamiya M1025 Hummer Front Gear Joint HM1041SF Aftermarket Steel by GPM  [HM1041SF]

This steel front gearbox joint is supplied as 1 piece and replaces the standard front joint used in the Tamiya M1025 Hummer model. It is intended to reduce failure where the original plastic part commonly wears.

Compatibility and application: the component is a direct aftermarket replacement for the M1025 Hummer front gearbox joint and is used in scale RC drivetrains to transfer torque to the front wheels. It is not suitable for full-size vehicles.

Fitting procedure: you must dismantle the front gearbox to remove the existing joint and fit the steel replacement. Standard workshop tools are adequate; ensure correct gear mesh and inspect bearings during reassembly to prevent drive bind.

Tuning effects: replacing plastic with steel lowers deformation under load and provides more consistent drivetrain behaviour, which can be useful when evaluating traction or suspension changes. Recheck clearances and adjacent part wear after fitment.
