The GPM MGO019 front C hubs are machined from 7075 aluminum to provide a precise, rigid mounting surface for the knuckle arms and upper tie rods on the ARRMA GORGON 4X2 MEGA 550 BRUSHED MONSTER TRUCK. These components reduce deformation at steering interfaces and improve load distribution under heavy impacts, making them a durable upgrade for racers and serious hobbyists seeking consistent steering geometry and extended component life.
