Key Features

• Extreme Heavy-Duty Construction — This component is engineered with reinforced materials and design specifications that far exceed standard duty requirements, meaning it can handle the intense forces generated during high-speed acceleration, hard cornering, and aggressive off-road driving without premature wear or failure.
• Pre-Assembled Stub Axle Integration — The stub axle comes fully assembled and integrated with the half shaft, saving you time on installation and ensuring perfect factory alignment and tolerances right out of the box, eliminating the guesswork from assembly.
• Universal Left or Right Fitment — This single part number accommodates both left and right rear axle positions, making it a convenient spare to have on hand for either side of your vehicle or for building multiple models without needing to stock different part numbers.
• Internal-Splined Half Shaft Design — The half shaft features internal spline geometry that provides superior engagement with differential output assemblies, ensuring positive power transmission and minimising the risk of slippage or disconnection during extreme driving conditions.
• Genuine Traxxas Quality — As an official Traxxas spare part manufactured to OEM specifications, this component guarantees perfect compatibility with your vehicle and maintains the performance standards your RC car was designed to deliver.
• Essential for Complete Driveshaft Assembly — This outer half shaft works in conjunction with Traxxas 6828A differential output assemblies to create a complete rear driveshaft assembly, providing a modular approach to drivetrain maintenance and customisation.

Frequently Asked Questions

• Which Traxxas RC models is the TRX6853A stub axle assembly compatible with? — The TRX6853A rear outer half shaft is confirmed compatible with the Traxxas Rustler Ultimate VXL 4x4 1/10 brushless models in both Green and Blue colour variants. However, as a Traxxas genuine spare part, it may also fit other models featuring the same differential output assembly specifications. We recommend checking your vehicle's manual or contacting our team at RC Model Shop to confirm compatibility with your specific model before ordering.
• Is this a complete replacement for my broken rear axle? — The TRX6853A provides the rear outer half shaft and stub axle components. To complete a full rear driveshaft assembly, you will also need the Traxxas 6828A differential output assemblies. If your vehicle also requires inner half shafts or other drivetrain components, please consult your vehicle's parts diagram or contact our expert team for guidance on additional parts needed.
• Why choose extreme heavy-duty over standard components? — Extreme heavy-duty components like the TRX6853A are specifically engineered to withstand significantly greater torque loads and stress than standard parts. If you regularly perform aggressive driving, compete in races, bash on challenging terrain, or simply want the ultimate in durability and reliability, extreme heavy-duty components are the smart choice. They reduce the likelihood of drivetrain failures during critical moments and provide superior longevity throughout the component's service life.
• Is professional installation required? — While installation difficulty depends on your mechanical experience level, Traxxas spare parts are designed for user installation on compatible models. If you are confident working with RC mechanical components and have the appropriate tools, you should be able to complete the installation. However, if you are new to RC maintenance or prefer professional assistance, our team at RC Model Shop is happy to discuss installation options with you.
• Can I use the TRX6853A on both left and right sides? — Yes, this is a key advantage of the TRX6853A design. A single part number accommodates both left and right fitment, making it convenient for spares or building multiple vehicles without requiring different part numbers for each side.
• What is the difference between this and standard duty stub axles? — The extreme heavy-duty designation means this component features enhanced material strength and design characteristics specifically engineered for high-performance and high-stress applications. Standard duty components may not withstand the same force levels, especially in competitive racing or aggressive off-road conditions. If you're serious about RC performance and reliability, extreme heavy-duty components are the superior choice.
