The Traxxas Ring Differential / Pinion Gear Differential (12 / 47 ratio) (Front) TRX6778 is an essential drivetrain component designed for RC enthusiasts looking to maintain or upgrade their Traxxas RC models. Whether you're a dedicated basher, a weekend racer, or someone serious about RC car performance in the UK, this genuine Traxxas spare part offers the precision engineering and reliability that comes from the manufacturer's own specifications. Differential gears are critical components in any RC vehicle's drivetrain, responsible for distributing power smoothly to the wheels whilst allowing them to rotate at different speeds during cornering. This particular ring and pinion gear set features a 12 / 47 ratio specifically designed for front differential applications, making it an ideal replacement or upgrade for compatible Traxxas models.
When you're investing in a quality RC car, whether it's a high-performance brushless RC buggy, a rugged RC monster truck, or any other scale model, maintaining original equipment manufacturer (OEM) parts ensures your vehicle performs at its best. The Traxxas Ring Differential / Pinion Gear Differential TRX6778 is manufactured to exact Traxxas specifications, guaranteeing compatibility and longevity. This is the kind of component that makes the difference between a smooth, responsive driving experience and one plagued by drivetrain issues. If you've experienced differential wear, gear slippage, or simply want to refresh your RC vehicle's drivetrain after extended use, this Traxxas spare part is the answer.
Available as a special order from Traxxas USA with a typical delivery time of 3 to 4 weeks, this part demonstrates the commitment Traxxas has to providing comprehensive support for their RC models across the UK and beyond. Whether you operate your RC cars on tarmac tracks, off-road terrain, or mixed surfaces, having access to genuine Traxxas replacement parts means you can keep your vehicles in peak condition for years to come. This is precisely why serious RC enthusiasts choose authentic manufacturer components rather than inferior aftermarket alternatives.

Technical Performance
The Traxxas Ring Differential / Pinion Gear Differential TRX6778 represents the engineering excellence that Traxxas brings to drivetrain components. Differential gears are engineered from precision materials selected for their ability to withstand the constant torque, impact loads, and friction inherent in RC vehicle operation. The 12 / 47 ratio provides a specific balance between acceleration and top speed characteristics, with the pinion gear (12 teeth) driving the larger ring gear (47 teeth), creating a reduction in rotational speed whilst multiplying torque output. This particular ratio has been carefully selected by Traxxas engineers for front differential applications, where it delivers optimal handling balance and power distribution. The gears are manufactured to exacting tolerances, ensuring smooth meshing, minimal backlash, and efficient power transfer from the motor to the axles. Whether you're running a brushless RC car at high speeds or a more modest bashable platform, these differential gears are built to endure sustained use, repeated acceleration cycles, and the occasional impact that comes with enthusiastic RC driving. The precision engineering extends to the gear teeth profiles, which are designed to minimise wear and ensure consistent performance over extended periods. For UK-based RC enthusiasts operating vehicles in varying conditions from indoor tracks to outdoor terrain, genuine Traxxas differential gears provide the reliability and performance consistency that separates quality builds from disappointing experiences.

Frequently Asked Questions
- What is a ring and pinion gear differential and why does my RC car need one? — The ring and pinion differential is the heart of your RC vehicle's drivetrain, transferring power from the motor to the wheels whilst allowing them to rotate at different speeds during cornering. Without a functional differential, your RC car would exhibit poor handling, increased tyre wear, and reduced overall performance. This Traxxas component ensures smooth power delivery and responsive vehicle control.
- What does the 12 / 47 ratio mean? — The ratio refers to the number of teeth on the pinion gear (12) and the ring gear (47). This creates a gear reduction of approximately 3.92:1, affecting how quickly the wheels turn relative to motor speed. The 12 / 47 ratio for front differential applications provides a balance suited to various driving styles and terrain conditions that Traxxas owners commonly encounter.
- Is this a front or rear differential component? — This is specifically a front differential component, as indicated by the product designation. Front and rear differentials may have different ratios and design characteristics to optimise handling and power distribution at each end of the vehicle. It is essential to order the correct differential for your vehicle's front or rear axle.
- How do I know if my differential needs replacing? — Signs that your differential may need replacement include grinding noises during cornering, loss of traction in one wheel during acceleration, visible damage to gear teeth, or notchy, inconsistent handling. If you've had a significant crash or driven through water without proper waterproofing, inspecting the differential is advisable. Regular maintenance extends differential life considerably.
- What is the typical delivery time for this part? — As noted in the product specifications, this is a special order from Traxxas USA, with a typical delivery time of 3 to 4 weeks. Planning ahead when you need replacement differentials ensures you're never left waiting too long to get your RC car back on the track or terrain.
- Is this genuine Traxxas or an aftermarket part? — This is a genuine Traxxas manufactured part, indicated by the official Traxxas part number TRX6778. Choosing genuine OEM parts over aftermarket alternatives ensures compatibility, longevity, and performance consistency that keeps your RC experience reliable and enjoyable.
- What level of RC experience do I need to install this differential? — Installing a differential requires moderate mechanical skills and familiarity with basic RC maintenance procedures. You'll need appropriate tools, a clean workspace, and possibly a service manual for your specific Traxxas model. If you're uncomfortable with the installation process, RC hobby shops and authorised Traxxas retailers often provide installation services.
