GMADE R1 Front & Rear Main Drive Shaft Set Steel and Aluminium - GM237SAAM by GPM  [GM237SAAM]

Front and Rear Main Drive Shafts

This front and rear main drive shaft set is made for the GMADE R1 Rock Buggy platform and carries the model number GM237SAAM. The assemblies use steel for high-stress sections and aluminium for the lighter interface pieces to balance torsional strength with reduced rotating mass, and the package contains two shafts for front and rear installation.

The shafts provide adjustable length ranges to suit axle and gearbox spacing on the R1 chassis, with the front shaft adjustable between 122mm-132mm and the rear shaft adjustable between 105mm-115mm. These ranges let you fine tune axle geometry when replacing stock components or upgrading to metal drivetrain parts.

These shafts couple to wheel hubs and transmission outputs; check hub bore and coupling method before fitting. Installation typically requires axle carrier removal and refastening with existing hex hardware, and it is good practice to inspect spline engagement and bearing fit after the first running sessions.

Choose these shafts when replacing worn drive components or when dialing in drivetrain stiffness on a GMADE R1 Rock Buggy; verify selected lengths and coupling details before final fitment.
