Overview
The Traxxas Fuel Tanks (left & right) / tank mounts (2) / tool boxes (left & right) TRX8845 is an essential replacement and upgrade kit designed specifically for Traxxas TRX-6 Ultimate RC Hauler owners. Whether you're a dedicated nitro RC enthusiast in the UK or someone looking to expand the capabilities of your ready-to-run RC truck, this comprehensive parts package offers genuine Traxxas quality and functionality. These fuel tank components represent the perfect solution for anyone who needs replacement parts following wear and tear, or who wants to optimise their RC vehicle's fuel storage and tool organisation capabilities.
Traxxas has engineered this kit to work seamlessly with the TRX-6 Ultimate RC Hauler platform, ensuring perfect fitment and reliability every time you take your RC car out for a session. The inclusion of both left and right fuel tanks means you have complete fuel storage flexibility, whilst the dual tank mounts provide secure, stable mounting that won't rattle or shift during high-speed runs. For serious RC enthusiasts who spend hours maintaining and tuning their vehicles, the integrated tool boxes on both sides offer convenient storage for essential maintenance items, spare parts, and tuning equipment—everything you need to keep your brushless or nitro-powered RC truck running at peak performance.
As an authorised Traxxas retailer across the UK, RC Model Shop stocks genuine OEM parts that guarantee compatibility and longevity. This is not an aftermarket alternative; this is the real deal from the manufacturer, ensuring your investment in RC hobby excellence is protected.
Key Features
- Left and Right Fuel Tanks — The kit includes both left and right fuel tanks, providing complete fuel storage solutions for your TRX-6 Ultimate RC Hauler and ensuring you have symmetrical, balanced fuel capacity across both sides of your vehicle.
- Dual Tank Mounts (x2) — Two robust tank mounts are included to secure your fuel tanks firmly to the chassis, preventing movement, vibration and potential fuel line damage during aggressive driving or high-speed performance.
- Integrated Tool Boxes (Left & Right) — Beyond fuel storage, this kit includes tool boxes on both the left and right sides, offering dedicated compartments for storing spare glow plugs, tuning screwdrivers, needle nose pliers, wire cutters, CA glue, and other essential maintenance items you'll need during breaks between runs.
- OEM Traxxas Quality — As official Traxxas parts, these components are manufactured to exact specifications and undergo rigorous quality control, ensuring perfect fitment with your TRX-6 Ultimate RC Hauler platform and compatibility with all related Traxxas systems.
- Complete System Integration — This kit is designed as a complete ecosystem for the TRX-6, meaning the fuel tanks, mounts, and tool boxes work together harmoniously to create an organised, efficient RC vehicle that's ready for serious recreational use or competition.
Technical Performance
The Traxxas TRX8845 fuel tank and accessory kit represents years of engineering refinement from one of the world's most respected RC manufacturers. These fuel tanks are precision-engineered to maintain perfect fuel delivery to your nitro engine's carburetor, with carefully designed fuel lines and filler necks that incorporate adjustable sealing systems. The orange o-rings on the fuel caps can be fine-tuned using a 2.5mm hex wrench to achieve the perfect seal—tight enough to prevent leaks during aggressive cornering and jumps, but not so tight that you struggle to refuel. The tank mounts are constructed from durable materials designed to isolate vibration and prevent fuel line stress, which is critical for maintaining consistent engine performance. The tool boxes provide weather-resistant storage, protecting your tuning tools, spare parts, and maintenance supplies from dirt and moisture during outdoor RC sessions. Whether you're running a TRX 2.5 or 3.3 nitro engine with the EZ-Start 2 system, or utilising the brushless alternative, these fuel tanks deliver the reliability and consistency that serious UK RC enthusiasts demand.

Frequently Asked Questions
- Is this kit compatible with my Traxxas RC truck? — Yes, the TRX8845 is specifically engineered for the TRX-6 Ultimate RC Hauler with Winch (model TRX88086-84-BLK). If you own this ready-to-run RC vehicle, this kit will fit perfectly and integrate seamlessly with your existing setup.
- Why would I need replacement fuel tanks for my RC truck? — Over time, fuel tanks can develop seal issues, cracks from impacts, or simply wear out from regular use. Additionally, if you want to upgrade your fuel storage capacity or replace damaged tanks, this genuine Traxxas kit ensures you get OEM-quality parts that will perform exactly as your vehicle was originally designed.
- How do I adjust the fuel tank cap seal? — The fuel cap includes an adjustable orange o-ring that seals into the tank's filler neck. Using a 2.5mm hex wrench, you can turn the adjustment screw clockwise to tighten the seal (spreading the o-ring for a snugger fit) or counterclockwise to loosen it. The o-ring should sit snugly in the filler neck and fit all the way down into the opening for proper sealing.
- What are the tool boxes used for? — The integrated left and right tool boxes provide storage for essential RC maintenance items such as spare glow plugs (#3231, #3232, or #3232X), small flat-tip engine tuning screwdrivers, #1 Phillips screwdrivers, medium-size wire cutters, needle nose pliers, CA glue for tyre traction, and fuel bottles. Having these items organised and accessible keeps your pit box tidy during RC running sessions.
- Can I use this kit with both nitro and brushless setups? — The fuel tanks are primarily designed for nitro-powered configurations using TRX 2.5 or 3.3 racing engines. However, the tool boxes and tank mounts are versatile and can be used with various TRX-6 configurations. Always consult your vehicle's manual and the compatibility information to ensure proper installation.
- Is this an official Traxxas product? — Absolutely. The TRX8845 is manufactured by Traxxas and distributed through authorised retailers like RC Model Shop. You're receiving genuine OEM parts with full Traxxas support and quality assurance, not third-party aftermarket alternatives.
- What's the best way to maintain these fuel tanks? — After each running session, inspect the fuel lines for cracks or leaks, wipe down the exterior of the tanks with a clean cloth, and ensure the cap seals properly. Before storing your RC truck, empty or partially empty the fuel tanks if you won't be running the vehicle for extended periods, as nitro fuel can gum up engine carburetors. Check the o-ring seal periodically and adjust with your 2.5mm hex wrench as needed.
