TraxxasTraxxas Driveshafts rear steel-spline constant-velocity (complete assembly) (2) TRA9052X are engineered to provide ultimate power handling and durability for high-output brushless RC systems. These heavy-duty shafts replace standard plastic components with high-grade steel to ensure that every ounce of motor torque is converted into forward momentum without the risk of twisting or snapping under load.
Designed for extreme bashing environments, these driveshafts utilize a sophisticated internal spline design that allows for seamless telescoping action. As your vehicle navigates rough terrain, the suspension moves through its full range of travel; these steel splines slide effortlessly to accommodate that movement, preventing the binding that often leads to drivetrain failure in lesser components. This smooth action ensures that your suspension remains active and responsive, providing better traction and control during high-speed maneuvers.
The constant-velocity (CV) joint design is a significant technical upgrade over traditional universal joints. By maintaining a consistent rotational speed regardless of the drive angle, these shafts eliminate the vibration and “chatter” that can occur when the suspension is fully compressed or extended. This reduction in vibration not only provides a smoother driving experience but also significantly extends the lifespan of your differential outdrives and hub bearings by reducing the mechanical stress placed upon them.
Constructed from premium hardened steel, these assemblies are built to withstand the punishing forces of 4S and 6S LiPo power. The metal is finished with a specialized corrosion-resistant coating, protecting the integrity of the steel against moisture, mud, and snow. This makes them an essential upgrade for drivers who refuse to let the weather dictate when they can hit the track or the trail. The ruggedness of the steel construction means you can land big-air jumps while staying on the throttle with confidence, knowing your drivetrain is built for the impact.
These driveshafts come as a complete, factory-assembled pair, which simplifies the upgrade process. There is no need for complex assembly or specialized tools to build the shafts from scratch; they are ready to be installed directly into your compatible Traxxas model. The precision machining ensures a perfect fit with existing hex hubs and differentials, maintaining the tight tolerances required for high-RPM stability and efficient power transfer.
By upgrading to these steel-spline CV shafts, you are investing in the long-term reliability of your RC vehicle. They solve the common problem of “u-joint pop-out” and shaft twisting that plagues high-voltage setups. Whether you are speed-running on asphalt or tackling technical off-road trails, these driveshafts provide the mechanical insurance needed to push your machine to its absolute limits without fear of a mechanical DNF.
