The X-Maxx is Traxxas's ultimate large-scale brushless monster truck, and these wheels are engineered to match its extreme performance capabilities.

Key Features

• Official Traxxas OEM Component — These are genuine manufacturer wheels built to the exact specifications required by the Traxxas X-Maxx platform, ensuring perfect fitment and reliability without any guesswork or compatibility issues.
• Large-Scale 1/7 Design — Engineered for the massive 1/7 scale X-Maxx monster truck, these wheels are proportionally larger than standard 1/10 scale wheels, delivering authentic looks and optimised ground clearance for extreme terrain.
• 17mm Hex Fitting — The industry-standard 17mm hex connection ensures secure attachment to your X-Maxx drive shafts, with a robust mechanical fit that resists vibration and maintains wheel alignment during high-speed driving.
• Professional Black Colour — The striking black finish complements any X-Maxx colour variant, whether you're running a green, red, blue or orange model, providing a sleek and aggressive appearance.
• Durable Plastic Construction — The wheels are manufactured from quality plastic material that balances weight reduction with impact resistance, important for maintaining responsive handling and reducing unsprung mass on this large-scale RC monster truck.
• Left and Right Pairing — This pack includes both left and right wheels, so you have a matched set ready to install, whether for a complete wheel change or as spares to keep in your pit bag.
• Universal X-Maxx Compatibility — Compatible with all current X-Maxx variants including the X-Maxx Ultimate in green and blue editions, plus all X-Maxx Belted 4WD Brushless RTR 8S models in red, green, blue and orange finishes.

Technical Performance

These Traxxas X-Maxx wheels are engineered to the highest standards expected from large-scale RC components. The 1/7 scale sizing is specifically calculated to work with the X-Maxx's 8S brushless drivetrain, which produces substantial torque and power delivery through the 4WD system. The 17mm hex fitting provides a solid mechanical interface for the 4WD transmission, critical given the forces generated by brushless acceleration and high-speed cornering. The plastic wheel construction, whilst lightweight, is formulated to resist the impacts and stresses of outdoor bashing, monster truck racing, and terrain that would damage lesser components. For UK-based RC enthusiasts operating their X-Maxx on grass, dirt, gravel and rough terrain, these wheels are designed to maintain their structural integrity through repeated jumps and hard landings. The black finish is not merely aesthetic; it also helps mask dirt and provides a professional race-ready appearance. When used as replacements on an existing X-Maxx, installation is straightforward thanks to the standard 17mm hex interface, requiring no modifications or adapters to your drive shafts or wheel carriers.

Frequently Asked Questions

• What Traxxas X-Maxx models are these wheels compatible with? — These TRX7771 wheels fit all current X-Maxx variants, including the X-Maxx Ultimate in green and blue versions (TRX77097-4-GRNX and TRX77097-4-BLUEX), and all X-Maxx Belted 4WD Brushless RTR 8S models in red, green, blue and orange finishes (TRX77096-4-RED, TRX77096-4-GRN, TRX77096-4-BLUE and TRX77096-4-ORNG). Verify your X-Maxx model number before ordering to ensure compatibility.
• Are these genuine Traxxas parts? — Yes, these are OEM (Original Equipment Manufacturer) wheels produced by Traxxas specifically for the X-Maxx platform. When you purchase from RC Model Shop, an authorised Traxxas retailer, you receive authentic components with full manufacturer backing and quality assurance.
• What is the hex size and how do they install? — The wheels feature a 17mm hex fitting, which is the standard connection for the X-Maxx drive system. Installation simply involves sliding the wheel onto your existing wheel hex shafts until they seat fully. No tools or modifications are required, making replacement quick and hassle-free.
• Can I use these wheels with different tyres? — These are wheels only and do not include tyres. You will need to fit your own tyres to these wheels, either by reusing your existing X-Maxx tyres if they are still in good condition, or by purchasing new Traxxas-compatible large-scale monster truck tyres separately. Check tyre compatibility with your specific X-Maxx model.
• Why would I need replacement wheels? — Wheels can become damaged through heavy bashing, impact with kerbs or rocks, or simply wear over time as an RC hobbyist uses their X-Maxx regularly. Having spare wheels means you can swap them quickly at the track or during a bash session without downtime, allowing you to continue driving whilst damaged wheels are repaired or replaced.
• What colour do these wheels come in? — The TRX7771 comes exclusively in black, a colour that complements all X-Maxx paint schemes and provides a professional, aggressive appearance suitable for any X-Maxx variant regardless of body colour.
• Are these suitable for both on-road and off-road use? — The X-Maxx is primarily an off-road monster truck designed for grass, dirt, gravel and rough terrain. These wheels are engineered specifically for that purpose and work best with appropriate all-terrain or off-road tyres fitted to them. Tyre choice will determine your exact use case, whether track racing, grass bashing or rocky terrain.
