Available as either a front or rear differential, the TRX10780 is specifically designed to fit Mini Maxx models perfectly, ensuring seamless installation without modification. The differential comes fully assembled and ready to install directly onto your Traxxas Mini Maxx, eliminating the need for complex rebuild procedures. This makes it an excellent choice for RC enthusiasts who want to upgrade their drivetrain without spending hours on assembly and adjustment.
Built using premium materials including 4140 carbon steel gears and 7075 aluminium components, this differential combines strength with efficient power transmission. The bevel gear design with sealed housing ensures consistent performance whether you're driving on pavement, dirt, or grass. Traxxas differentials are recognised as industry-leading components that can handle the torque output from modern brushless motors, making this an investment in your RC car's longevity and reliability.
Key Features
- Complete Assembly Ready to Install — This differential arrives fully assembled and can be installed directly on your Traxxas Mini Maxx without requiring any internal assembly or rebuilding, saving you time and effort on maintenance or upgrades.
- Bevel Gear Differential Design — The sealed bevel gear differential is engineered to hold silicone differential oil and provide smooth, consistent power distribution to the wheels, ensuring stable handling and predictable traction control across all driving conditions.
- Premium 4140 Carbon Steel Construction — The internal gears are manufactured from high-strength 4140 carbon steel, which provides superior durability and can effectively transmit the torque output from brushless motors without premature wear or failure.
- 7075 Aluminium Housing — The differential housing is constructed from lightweight yet incredibly strong 7075 aluminium alloy, offering excellent heat dissipation and long-term reliability whilst keeping weight to a minimum for optimal RC car performance.
- Larger Module Teeth Design — This differential features teeth with a larger 0.8mm module compared to original components, which enables more effective torque transmission and reduces power loss during acceleration and turns, resulting in more direct and efficient power delivery to your RC car's wheels.
- Improved Gear Meshing — The increased tooth thickness of this upgraded differential creates closer, more precise gear meshing, which minimises power loss and ensures maximum efficiency in translating engine output to wheel movement.
- Fits Multiple Mini Series Models — Compatible with Traxxas Mini Maxx, Mini XRT, Mini Slash 4x4, and Mini Rally VXL platforms, giving you flexibility if you own multiple RC models in the Mini series range.
- Front or Rear Configuration — Available as either a front or rear differential, allowing you to upgrade single axles or both for complete drivetrain enhancement.
Technical Performance
This differential assembly represents a significant engineering upgrade over standard Mini Maxx components. The 13-tooth pinion and 37-tooth ring gear configuration with 0.8mm module delivers measurably superior performance in torque transmission compared to original factory equipment. The bevel gear design with sealed housing prevents differential oil leakage whilst maintaining consistent viscosity and lubrication properties essential for smooth operation. The combination of 4140 carbon steel gears with 7075 aluminium housing creates an optimal balance between strength and weight, crucial for high-performance RC vehicles. The larger module teeth are engineered to handle the continuous torque demands of brushless electric motors whilst reducing parasitic losses that would otherwise be converted to heat. For RC enthusiasts in the UK pushing their Mini Maxx hard across varied terrain, this differential provides the reliability and efficiency needed for consistent performance lap after lap, whether you're on carpet, tarmac, or outdoor dirt tracks. Installation requires self-adjustment of gear meshing clearance using the included gaskets (0.2x8x13 or 0.3x8x13 mm), which is a straightforward procedure that most RC car owners can complete in their workshop.

Frequently Asked Questions
- Will this differential fit my Traxxas RC car? — This TRX10780 differential is specifically designed to fit Traxxas Mini Maxx, Mini XRT, Mini Slash 4x4, and Mini Rally VXL models. It will not fit other Traxxas models or different manufacturers' RC cars. Always verify your exact model number before purchasing to ensure compatibility.
- Do I need to purchase both front and rear differentials? — You can upgrade either the front differential, the rear differential, or both simultaneously. Many owners start by upgrading the rear for improved acceleration and traction, then add a front differential upgrade later. The choice depends on your driving style and performance goals.
- What differential oil should I use? — 50,000 cSt (50K) silicone differential oil is recommended for optimal performance with this assembly. This viscosity provides the right balance between smooth operation and torque transmission efficiency. Always use proper RC-grade differential oil, not automotive oil substitutes.
- Is this suitable for beginners? — Yes, this differential is suitable for RC enthusiasts of all skill levels. The assembly comes fully prepared, and installation is straightforward with basic RC tools and moderate mechanical knowledge. If you're new to RC maintenance, consulting online installation guides or visiting an RC hobby shop for guidance is recommended.
- What is the difference between this and the original Traxxas differential? — This upgraded differential features larger module (0.8mm) teeth compared to the original, providing more effective torque transmission, reduced power loss, and closer gear meshing. The combination of 4140 carbon steel gears and 7075 aluminium housing also offers improved durability and heat dissipation compared to standard components.
- Do I need to adjust anything after installation? — Yes, you'll need to adjust the gear meshing clearance yourself using the included gaskets. This is a normal RC maintenance procedure that ensures optimal differential performance. The gaskets allow you to fine-tune the clearance between the pinion and ring gear for maximum efficiency.
- Is this a quality upgrade for my Mini Maxx? — This is a recognised quality upgrade that significantly improves drivetrain performance and longevity. If you're running a brushless Mini Maxx hard or racing competitively, upgrading to this differential will provide noticeably better power transmission, reduced noise, and improved reliability compared to original components.
