Cobra Racing Traxxas X-Maxx / XRT 7075-T6 Aluminum Center Differential – 51T
$99.95

Built for big-power X-Maxx and XRT setups, the Cobra Racing 7075-T6 Aluminum Center Differential is a serious driveline upgrade designed to handle the torque, weight, and abuse these trucks are known for.
The centerpiece is a precision-machined 7075-T6 aluminum differential housing, chosen for its outstanding strength-to-weight ratio and resistance to flex under heavy load. Compared with softer aluminum alloys, 7075-T6 provides substantially greater structural rigidity—exactly what you want when hard launches, oversized tires, high-traction surfaces, and aggressive 6S/8S power are putting maximum stress through the center drivetrain.
A hardened steel 51-tooth main gear delivers a large, durable contact surface for dependable power transfer. The matching steel input gear completes the drive system, giving you an integrated upgrade rather than simply replacing the housing.
The result is a center differential assembly engineered for high-load RC use while adding a premium CNC-machined appearance to the X-Maxx or XRT drivetrain.
Why Upgrade Your Center Differential?
High-powered X-Maxx and XRT builds can generate enormous instantaneous drivetrain loads. A rigid aluminum housing helps maintain gear alignment under acceleration and impact, while the steel gearing is designed to withstand repeated high-torque use.
Whether you’re rebuilding a worn drivetrain, upgrading for larger tires and higher loads, or simply building a stronger X-Maxx/XRT, this assembly is made for demanding setups.
