Key Features
- Extreme Heavy-Duty Construction — This axle assembly is purpose-built with heavy-duty specifications that provide significantly greater strength and durability compared to standard components, allowing it to withstand the higher torque loads generated by brushless powertrains and high-performance driving styles.
- Fully Assembled Design — The stub axle comes pre-assembled with the internal-splined half shaft, saving you time and ensuring factory-correct alignment and fitment, which means you can install it straight into your RC vehicle without additional assembly steps.
- Fits Left or Right — This single part number is designed to work as either a left-side or right-side rear axle assembly, providing versatility and simplifying inventory for builders and upgraders who need to replace either side of the drivetrain.
- Internal-Splined Half Shaft — The internal spline design provides secure, reliable power transmission from the differential to the wheels, ensuring consistent torque delivery and minimising slippage during acceleration and cornering.
- Part of the #9080 Upgrade Kit System — This component is specifically engineered to work within Traxxas's #9080 upgrade kit ecosystem, ensuring compatibility and performance synergy with other extreme heavy-duty components in the system.
- Designed for High-Performance RC Trucks — This axle is engineered specifically for use with high-performance 4WD RC short course trucks and stadium trucks that demand extreme durability during competitive and recreational driving.
Technical Performance
The Traxxas TRX9055 rear stub axle assembly represents the pinnacle of drivetrain durability engineering for 1/10 scale RC trucks. Constructed with extreme heavy-duty specifications throughout, this component is engineered to handle the massive torque loads generated by modern brushless electric motors and high-capacity LiPo battery systems that power today's high-performance RC vehicles. The assembly features an internal-splined half shaft design that provides secure power transmission with minimal backlash, ensuring efficient torque delivery from the differential to the wheel hubs. The stub axle itself is manufactured to exacting tolerances and uses materials and construction techniques proven in competitive RC racing environments. This is a replacement rear outer axle designed for the Traxxas Hoss 4X4 VXL, Rustler 4X4 VXL, Slash 4X4, Slash 4X4 Ultimate, and Slash 4X4 VXL models. The extreme heavy-duty designation means this component exceeds the strength specifications of standard axle assemblies, making it ideal for bashers who regularly push their vehicles to the limit. Installation requires the corresponding 6828A differential output assemblies for a complete driveshaft assembly, and this component is part of the comprehensive #9080 upgrade kit upgrade path that Traxxas offers for platform enhancement.

These components work together as a system to transmit power from the differential to the wheels, so both parts are necessary for proper installation.
- Is this part suitable for brushless RC trucks? — Yes, this extreme heavy-duty specification is specifically engineered to handle the high torque loads generated by brushless electric motors. The heavy-duty construction is actually designed with brushless powertrains in mind, making it an excellent choice for owners of brushless Traxxas 4WD trucks.
- What makes this extreme heavy-duty compared to standard axles? — The extreme heavy-duty designation indicates that this axle assembly exceeds standard strength specifications in materials, design, and construction. It is engineered to withstand greater forces and stress loads, making it ideal for aggressive bashing, high-speed driving, and competitive use where durability is paramount.
- Can I use this part as either left or right rear axle? — Yes, the TRX9055 is designed to fit either the left or right rear position, providing flexibility when replacing damaged components or upgrading both sides of the drivetrain.
- Is this a complete rear axle replacement? — This component is a rear outer stub axle assembly. For a complete driveshaft assembly, you will also need the 6828A differential output assemblies. Together, these components provide a complete rear axle system for your compatible Traxxas RC truck.
