Swap in the GPM MGG4951V2 drive shafts to give your ARRMA Granite GROM a stronger drivetrain. Built from 4140 carbon steel, the front and rear CVDs increase torsional resistance and reduce wear. The package uses 7075-T6 aluminum hex adapters for a precise fit, while CNC machined steel wheel stub axles replace the stock dog bone and plastic shafts to boost dependability. Pin diameter has been uprated from 1.5mm to 2mm for firmer tracking at higher speed.
