The GPM Aluminum Center Gear Box Differential Lock Servo Mount is engineered to firm up servo mounting and support the differential lock on the Traxxas TRX4. Fabricated from 6061 T6 aluminium with a precision approach and CNC machined finish, the component aims to increase structural rigidity while keeping weight low. Its 3D streamlined profile and hollow cut sections minimise mass without sacrificing strength, making it a suitable performance upgrade for demanding hobbyists focused on durability and tuning potential.
