This two-piece main drive shaft set is built for the GMADE R1 Rock Buggy and carries model GM237SAAM. Steel is used where load and wear are highest while aluminium is used at the interfaces to help reduce rotating mass, and the supply includes both front and rear shafts in a 2pcs set.
Adjustable length ranges let you tune axle spacing: front 122mm to 132mm and rear 105mm to 115mm. Those ranges let you match axle and gearbox offsets on R1 chassis variants when swapping out stock parts or upgrading to metal components.
Confirm hub bore size and coupling method before fitting as these shafts mate to wheel hubs and transmission outputs. Fitting usually involves axle carrier removal and reassembly with compatible hex hardware; check spline engagement and bearing clearance after initial test runs.
Use this set to replace worn shafts or to firm up drivetrain response on a GMADE R1; always set lengths and coupling details to preserve correct axle geometry.
