ARA311118 is an aluminum center differential set designed for compatible ARRMA 1/7 and large 1/8 scale remote control vehicles. The unit comes pre‑assembled and factory‑filled with high‑viscosity silicone oil to help provide consistent differential action without the need to fill it yourself. It uses strong steel internal gears and outdrives paired with a 50‑tooth steel center spur gear to handle high torque and demanding driving conditions. The precision‑machined aluminum housing increases stiffness and durability compared with standard composite cases, and the set includes metal cross shafts, inserts, and bearings to support smooth operation and reliable fitment in the vehicle’s drivetrain. This center diff set is used as either a replacement or performance upgrade in models that require a 50 T center differential configuration.
