The grey colour option provides a sleek, professional appearance while the heavy duty construction ensures your truck can handle whatever you throw at it. This is not just a single upgrade; it's a complete transformation of your vehicle's handling, durability, and performance characteristics.

Designed with brushless motor systems in mind, every component in this kit has been engineered to work in perfect harmony. The package includes hex hardware and is compatible with existing aluminium accessories, making installation straightforward for anyone with basic RC maintenance experience. This all-inclusive approach means you're getting parts that are proven to work together, eliminating the guesswork often involved in piecing together individual upgrades from multiple sources.

Key Features

• Heavy Duty Caster Blocks, Steering Blocks and Hub Carriers — These critical chassis components are beefed up with extra material in all the right places to withstand extreme impacts and high-speed collisions. The reinforced caster blocks and steering blocks are specifically designed to take a pounding, whilst the hub carriers provide additional strength where suspension loads are greatest. This upgraded construction means your truck will maintain alignment and structural integrity even after repeated hard bashing sessions.
• Extreme Heavy Duty Driveshafts — The driveshafts included in this kit are larger in diameter than standard alternatives, featuring beefed-up U-joints that are specifically engineered to handle brushless power with ease. The telescoping design provides superior suspension articulation, which translates to excellent shock absorption and tighter, more responsive turning characteristics that improve overall handling on any terrain.
• HD Front and Rear Suspension Arms — Moulded from Traxxas's toughest composite material, these heavy duty suspension arms provide just the right amount of flex to resist breaking whilst maintaining structural integrity under extreme stress. The composite construction allows the arms to absorb impacts without snapping, which means your truck can recover from hard crashes that would damage standard plastic components and keep performing at peak levels.
• One-Piece HD Camber and Toe Links — These precision-engineered components maintain your truck's suspension geometry under all driving conditions, ensuring consistent handling whether you're bashing hard or running at high speed. One-piece construction eliminates potential failure points found in multi-part designs, providing superior reliability and longevity during intensive use.
• Steel Rear Wheel Hexes — The steel hex adapters provide maximum strength at the wheel mounting point, the most critical connection on any RC vehicle. Steel construction resists bending and breaking far better than plastic alternatives, ensuring your wheels stay securely attached even during violent impacts and aggressive cornering manoeuvres.
• Sealed Outer Bearings — Premium sealed bearings prevent dirt, dust and moisture from compromising smooth rotation, maintaining performance over extended periods of use. This sealed design extends the life of your drivetrain components and reduces maintenance requirements between bashing sessions.
• Hex Hardware Included — This upgrade kit comes with all necessary hardware, eliminating the need to source fasteners separately. Having the correct hardware ensures perfect assembly and prevents compatibility issues that can arise from using incorrect bolt specifications.
• Compatible with Existing Aluminium Accessories — The upgrade kit integrates seamlessly with any aluminium hop-up parts you may have already installed on your truck, protecting your existing investment whilst significantly improving overall durability and performance.
• Engineered for Brushless Power Systems — Every component in this kit has been specifically designed and tested to handle the higher power outputs and torque levels produced by brushless motor systems, making this upgrade essential if you're running or planning to run a brushless setup on your 2WD truck.

Technical Performance

The Extreme Heavy Duty Upgrade Kit represents a comprehensive approach to strengthening the most critical systems on your 2WD Rustler, Stampede or BIGFOOT. The engineering philosophy behind this kit focuses on strategic material placement and component design to maximise durability without adding unnecessary weight. The larger-diameter driveshafts with reinforced U-joints are a significant upgrade over standard items, with the telescoping design allowing greater suspension travel and smoother weight transfer during aggressive manoeuvres. The suspension arms, moulded from composite materials that have been stress-tested in extreme conditions, provide the flexibility needed to absorb impacts whilst maintaining the rigidity required for precise handling. The caster blocks and steering blocks, with their extra material in high-stress areas, work in conjunction with the sealed bearings to create a suspension system that can endure repeated high-impact collisions. The one-piece camber and toe links eliminate potential weak points in suspension geometry, ensuring your truck maintains consistent handling characteristics throughout every bashing session. Steel rear wheel hexes provide the ultimate in connection reliability, preventing the wheel attachment failures that plague trucks running standard plastic hexes under brushless power. This complete system is designed to work as an integrated package where all components complement each other, creating a truck that is substantially more durable than one built with a mix of standard and upgraded parts. The kit's compatibility with existing aluminium accessories allows you to maintain any upgrades you've already invested in whilst filling critical durability gaps.

Frequently Asked Questions

• Will this Extreme Heavy Duty Upgrade Kit work with my standard brushed motor truck? — Whilst this kit is engineered specifically for brushless power systems, it can technically be installed on brushed motor trucks. However, since the components are designed to handle the higher torque and power outputs of brushless motors, you may find the upgrade more beneficial if you plan to upgrade your motor to brushless in the future. The sealed bearings and reinforced construction will still provide durability benefits even with a brushed setup.
• How difficult is it to install this complete upgrade kit? — The kit is designed for easy installation as an all-inclusive package. Everything is engineered to fit together with perfect precision, and since it includes hex hardware, you should have all fasteners needed. If you have basic RC maintenance experience and the right tools, installation is straightforward. The instruction materials will guide you through the process of replacing your existing driveline and suspension components with the upgraded parts from the kit.
• What models does this kit fit? — This Extreme Heavy Duty Upgrade Kit is designed to fit 2WD versions of three popular Traxxas models: the Stampede 2WD, the Rustler 2WD, and the BIGFOOT 2WD. It will not fit the 4WD versions of these trucks, so please confirm your model before ordering. The kit is specifically engineered for these model platforms to ensure perfect fitment and function.
• Will I need to replace other parts on my truck after installing this upgrade? — The Extreme Heavy Duty Upgrade Kit transforms the outer driveline and suspension systems, addressing the components most prone to failure during aggressive bashing. However, depending on the condition of your truck and how intensively you drive, you may eventually want to consider upgrades to other systems. The kit is designed to be compatible with existing aluminium accessories, so any previous upgrades you've made will continue to work with this new system.
• What makes the sealed bearings in this kit better than standard bearings? — Sealed bearings prevent dirt, dust, moisture and other contaminants from entering the bearing races, which would cause friction, noise and eventual failure. In a bashing environment where your truck encounters mud, sand, grass and water, sealed bearings maintain smooth operation far longer than unsealed alternatives. This means better performance throughout the life of your truck and reduced maintenance requirements between sessions.
• Can I use this upgrade kit if I've already installed other aftermarket parts? — Yes, this is one of the key advantages of the Extreme Heavy Duty Upgrade Kit. It's specifically designed to be compatible with existing aluminium accessories you may have already installed on your truck. This compatibility means you can integrate this comprehensive upgrade without needing to replace expensive hop-up parts you've already purchased.
