This center diff is designed as a direct OEM replacement or upgrade for compatible Redcat models. It balances torque transfer between front and rear wheels while allowing differential action — meaning the front and rear sections can rotate at different speeds during cornering. That helps reduce drivetrain bind, improve steering performance, and extend the life of gears and driveshafts. The unit arrives fully assembled and ready to install. Key Features Complete center differential assembly — ready to install in compatible Redcat 4WD vehicles. Balances front and rear power delivery to improve traction and handling. Pre‑assembled unit reduces build time and simplifies replacement. Helps protect drivetrain components by allowing smoother rotation and reducing binding under load. OEM‑level quality built for hobby‑grade RC use.
