Key Features
- Pro-Built Centre Differential Design — The sealed differential absorbs driveline shocks to improve durability and distributes power to all four wheels for mind-bending acceleration, meaning you'll experience smoother, more predictable handling and better traction in all driving conditions, whether you're racing on track or bashing off-road.
- 54-Tooth, 32-Pitch Steel Spur Gear — The hardened steel construction provides maximum durability and longevity, ensuring your differential can handle the demands of high-performance RC driving without premature wear or failure, making this a long-term investment in reliability.
- Sealed Differential Housing — The sealed design completely protects internal differential components from dirt, mud, water and debris, which means your RC car will maintain consistent performance even in challenging outdoor environments and dirty track conditions.
- Pre-Filled with 500K Silicone Oil — The differential arrives completely assembled with 500K grade silicone oil pre-installed to help prevent unloading and ballooning of the front tyres, which improves handling precision and extends the lifespan of your tyres during high-speed runs and aggressive cornering.
- Complete Ready-to-Install Assembly — This differential comes fully assembled and ready to install immediately, eliminating the need for complex assembly work and allowing you to get your RC vehicle back on the track or trail faster, making it perfect for weekend racers and bashers alike.
- Compatible with Multiple Traxxas Models — This upgrade is designed to fit the Hoss 4X4 VXL, Rustler 4X4 VXL, Stampede 4X4 VXL, Slash 4X4 Brushless, Ford F-150 Raptor R and several other Traxxas 4WD platforms, making it a versatile upgrade option for owners with different RC vehicles.
- 32-Pitch Pinion Gear Compatibility — The centre differential requires a 32-pitch pinion gear, ensuring compatibility with standard Traxxas transmission components and allowing for straightforward installation into your existing RC vehicle setup.
Technical Performance
The Traxxas Center Differential TRX6780A represents the pinnacle of differential engineering for 1/10 scale 4WD RC vehicles in the UK RC hobby market. Built with a precision-machined 54-tooth, 32-pitch steel spur gear, this component delivers exceptional durability whilst maintaining the smooth power delivery that distinguishes high-quality RC transmissions from budget alternatives. The sealed housing design is critical for maintaining consistent performance across diverse driving conditions — whether you're running your brushless RC truck on dusty outdoor tracks, through muddy terrain, or in wet weather, the sealed differential protects internal gears and bearings from contamination that would otherwise degrade performance over time. The pre-filled 500K silicone oil serves multiple critical functions: it lubricates internal differential components for smooth operation, helps maintain consistent traction by preventing tyre unloading during acceleration, and reduces the ballooning effect that occurs in the front tyres during hard cornering. This is particularly important for high-performance 4WD models like the Hoss 4X4 VXL, which demand precision transmission components to realise their full potential. The complete assembly approach means every component is factory-aligned and tested, eliminating variables that might arise from home assembly and ensuring reliability from the moment you install it in your RC car. Whether you're upgrading an existing Traxxas vehicle or replacing a worn differential, this Pro-Built unit represents a genuine performance and reliability upgrade.

Frequently Asked Questions
- Which Traxxas RC models does the TRX6780A center differential fit? — This Pro-Built centre differential is compatible with the Hoss 4X4 VXL, Rustler 4X4 VXL, Stampede 4X4 VXL, Slash 4X4 Brushless, Ford F-150 Raptor R 4X4, Rustler 4X4 Brushless, Slash 4X4 Ultimate and Stampede 4X4 Brushless. Always verify compatibility with your specific model before ordering, as installation requirements may vary between platforms.
- What makes this centre differential better than the standard unit? — The Pro-Built designation indicates this is a complete, factory-assembled unit with sealed housing, pre-filled silicone oil, and precision-engineered components including the 54-tooth steel spur gear. This sealed design protects against dirt and moisture, whilst the pre-filled oil helps prevent front tyre unloading and ballooning, delivering superior performance and durability compared to unsealed alternatives.
- Do I need any tools or special equipment to install this differential? — This centre differential comes completely assembled and ready to install, meaning you won't need to disassemble or rebuild it. However, you'll need basic RC tools to remove your existing differential and install this replacement unit, along with a compatible 32-pitch pinion gear to complete the transmission setup.
- Why does this differential use 500K silicone oil? — The 500K grade silicone oil is specifically chosen to lubricate the differential gears whilst preventing unloading of the front tyres during hard acceleration and braking. This viscosity grade helps maintain consistent traction and reduces the ballooning effect that occurs when front tyres lose load, improving overall handling precision and tyre longevity during high-performance driving.
- Is the TRX6780A suitable for beginner RC drivers? — This is a replacement differential component designed for existing Traxxas 4WD vehicles rather than a complete ready-to-run RC car, so it's best suited for owners already familiar with their RC models and basic maintenance. If you're new to the RC hobby, you might start with a complete ready-to-run RC car and then upgrade components like this differential as you gain experience.
- How often should I service or replace this centre differential? — With proper maintenance and the sealed design protecting internal components, this differential should provide years of reliable service. However, if you notice excessive tyre wear, handling inconsistencies, or grinding noises from the transmission, it may be time to inspect or replace the differential. Regular inspection as part of your RC car maintenance routine will help you identify any issues early.
- What is the difference between this Pro-Built unit and aftermarket differentials? — Traxxas Pro-Built components are engineered specifically for Traxxas vehicles and undergo rigorous testing to ensure compatibility and performance. The sealed housing, pre-filled oil, factory assembly and precision machining ensure this unit delivers the reliability and performance that Traxxas is recognised for, with guaranteed compatibility with your specific RC model.
- Will upgrading to this centre differential improve my RC car's performance? — Yes, upgrading to this Pro-Built centre differential can improve your RC car's durability, handling consistency and traction distribution across all four wheels. The sealed design protects components from dirt and moisture, whilst the precision engineering and pre-filled silicone oil deliver smoother power delivery and reduced tyre wear, particularly noticeable during aggressive cornering and acceleration.
