Install the GPM MGG4951V2 set to reinforce your ARRMA Granite GROM's drivetrain. These CVD drive shafts are machined from 4140 carbon steel for higher torsional strength and improved wear resistance. Hex adapters are made from 7075-T6 aerospace aluminum for accurate seating, and CNC machined steel wheel stub axles replace the weaker dog bone and plastic wheel shafts for better durability. Reinforced pins move from 1.5mm up to 2mm to help maintain stability during demanding runs.
