TAMIYA M1025 Hummer Rear Gear Box Joint by GPM HM1041SR  [HM1041SR]

Steel rear gearbox joint for M1025 Hummer

This is a steel rear gear box joint made for the Tamiya M1025 Hummer platform and produced as an aftermarket replacement by GPM HM1041SR. It is sold as 1 pcs and intended strictly as an RC-scale part to replace a rear gearbox joint on compatible Tamiya chassis.

The component provides a metal alternative to typical plastic joints, intended to offer a stiffer connection in the rear drivetrain for tuning or durability-focused builds. The part fits into the vehicle's rear gearbox assembly and should be installed in place of the original joint using the existing mounting arrangement on the chassis.

When fitting, verify alignment and clearances within the rear gearbox, inspect surrounding bearings and gears for wear, and confirm smooth rotational movement before reassembling the vehicle. Use standard RC maintenance practice when tightening fasteners and testing on the bench before running.
