GMADE R1 Front and Rear Adjustable Main Drive Shaft Set GM237SAA by GPM  [GM237SAA]

Adjustable main shafts for front and rear driveline

This center main drive shaft set fits the GMADE R1 ROCK BUGGY chassis, model GM237SAA. The kit combines steel retention hardware with an aluminium 6061 T shaft body to balance local strength and lower rotating mass.

The front shaft is adjustable between 122mm and 132mm while the rear spans 105mm to 115mm, giving clearance for common setup changes and trimming during alignment. A steel wire ring locks the screw fittings to help keep fasteners secure under vibration.

For tuning and maintenance, the aluminium body cuts spinning mass versus a full-steel shaft, which can sharpen drivetrain response. The adjustable sections let you fine tune run-lengths for slipper or differential spacing without cutting fixed pieces.

Choose these shafts when replacing worn drive parts or when adjustable lengths make setup easier; confirm lengths before final fitting and recheck fasteners after the first runs.
