Traxxas Outer Driveline & Suspension Upgrade Kit, extreme heavy duty, Green TRX9080G

Overview

The Traxxas Extreme Heavy-Duty Upgrade Kit in green (TRX9080G) is a comprehensive driveline and suspension transformation package designed to turn your already-tough 4WD RC short course truck into the ultimate bashing machine. Whether you're an experienced RC enthusiast looking to upgrade your Slash 4x4, Rustler 4x4, or Hoss 4x4, or a UK-based RC car collector wanting to push your brushless RC vehicle to its limits, this complete kit delivers battle-hardened performance engineered specifically for extreme brushless power systems. The kit includes a full complement of precisely engineered parts designed to work together as a complete package, making it ideal for weekend bashers at the skate park, competitive runners preparing for speed events, or anyone serious about taking their RC short course truck to the next level.

Built with Traxxas' legendary durability in mind, this extreme heavy-duty upgrade kit transforms your existing chassis with overbuilt components made from the toughest composite materials. Every component has been engineered to withstand brutal punishment from high-powered brushless motors like the Velineon 540XL, ensuring your RC truck comes back for more after intense bashing sessions. The green colour variant adds a striking visual appeal whilst maintaining the professional, race-ready aesthetic that Traxxas is recognised for throughout the UK RC community.

What sets this upgrade kit apart is its comprehensive approach to driveline and suspension enhancement. Rather than replacing individual components, the Extreme Heavy-Duty Upgrade Kit provides everything needed as a coordinated system, with parts engineered to work together perfectly. Installation is straightforward thanks to the included replacement hardware, and the kit works seamlessly with either standard or HD suspension arms, giving you flexibility in your upgrade approach.

Key Features

• MaxxDuty Driveshafts — Huge-diameter driveshafts with heavy-duty U-joints are built to handle the extreme torque delivered by brushless motors like the Velineon 540XL with absolute ease, providing reliability you can count on during the most demanding runs.
• 6mm Steel Axle Hubs — Large 6mm axles key into included steel wheel hexes, delivering unmatched strength and durability that prevents slipping and ensures consistent power delivery to your tyres even under extreme acceleration.
• Heavy-Duty Caster and Steering Blocks — Made from Traxxas' toughest composite material and beefed up with extra material where it counts most, these upgraded blocks are built to absorb the punishment of aggressive driving whilst maintaining precise steering response.
• Heavy-Duty Axle Carriers — Constructed from the same toughened composite compound as the caster and steering blocks with additional material in critical stress areas, these carriers work together with larger sealed bearings for ultimate durability and precision handling.
• Oversized Sealed Bearings — The steering blocks and axle carriers both feature larger sealed bearings that provide superior durability, smoother operation, and extended life even when subjected to constant high-speed runs and impact.
• Heavy-Duty Shock Towers — New shock towers and body mounts made from tough composite material have been redesigned to readjust the roll centre and properly accommodate the larger MaxxDuty driveshafts for optimised suspension geometry.
• Complete Installation Package — All replacement hardware is included in this all-inclusive kit, meaning everything you need comes in the box and fits together with perfect precision to transform your truck completely.
• Compatible with HD Suspension Arms — The kit works seamlessly with either standard or heavy-duty suspension arms, giving you flexibility in how you configure your upgrade based on your specific truck model and driving style.
• Engineered for Extreme Brushless Power — Every component in this kit has been specifically designed and tested to handle the extreme torque and power delivered by modern brushless motor systems, ensuring nothing breaks under sustained high performance.

Technical Performance

The Traxxas Extreme Heavy-Duty Upgrade Kit represents a complete rethinking of driveline and suspension strength for 1/10 scale 4WD RC short course trucks. Built around the MaxxDuty driveshaft system, this kit features huge-diameter driveshafts with heavy-duty U-joints that can handle the extreme torque output of brushless motors like the Velineon 540XL without fear of breakage or flex. The 6mm steel axles key into matching steel wheel hexes, creating a mechanical interface that is simply incompatible with slipping or performance degradation. The caster blocks, steering blocks, hub carriers, and shock towers are all manufactured from Traxxas' toughest cold-weather composite material, with strategic reinforcement in high-stress areas. What makes this kit exceptional is the attention to bearing specification—both the steering blocks and axle carriers utilise larger sealed bearings compared to standard components, providing superior durability, smoother operation, and improved precision. The shock tower redesign specifically addresses the geometry changes required when running the larger MaxxDuty driveshafts, readjusting the roll centre to maintain optimal suspension characteristics. The entire kit is designed as a coordinated system where every component works with every other component, rather than as individual bolt-on upgrades. This engineering approach ensures that suspension geometry, driveline strength, and chassis dynamics all work together harmoniously.

Frequently Asked Questions

• Which Traxxas 4WD trucks is this upgrade kit compatible with? — The Extreme Heavy-Duty Upgrade Kit (TRX9080G) is compatible with the Slash 4x4, Rustler 4x4, and Hoss 4x4. It has been specifically engineered to work as a complete package with these models, transforming them into ultimate bashing machines capable of handling extreme brushless power systems.
• Is this kit suitable for brushless motor upgrades? — Yes, this kit is engineered specifically for extreme brushless power systems. The driveshaft diameter, U-joint design, bearing size, and material composition are all optimised to handle the high torque output of brushless motors like the Velineon 540XL without degradation or failure.
• Can I use this kit with either standard or heavy-duty suspension arms? — Yes, the kit is fully compatible with both standard suspension arms and heavy-duty suspension arms, giving you flexibility in how you configure your upgrade based on your specific model and performance requirements.
• What makes this kit different from upgrading individual components separately? — This kit is engineered as a complete system where every component is designed to work together harmoniously. The shock tower redesign specifically addresses geometry changes required by the larger MaxxDuty driveshafts, and all parts have been tested together to ensure optimal performance. Upgrading components individually often results in mismatched geometry and performance characteristics that this kit avoids entirely.
• Does the kit include all hardware needed for installation? — Yes, all replacement hardware is included in the kit. This all-inclusive package means you have everything needed to transform your truck without needing to source additional fasteners or components.
• Are the bearings in this kit different from standard components? — Yes, the steering blocks and axle carriers both feature larger oversized sealed bearings compared to standard components. These larger bearings provide superior durability, smoother operation, and extended service life even under constant high-speed running and impacts.
• What is the benefit of the steel wheel hexes included in this kit? — The large 6mm axles that key into the steel wheel hexes create an extremely strong mechanical interface with unmatched durability. Steel hexes prevent slipping and ensure consistent, reliable power delivery to your wheels even under extreme acceleration and aggressive driving conditions.
