Overview
The Traxxas Gear Set, Differential (TRX7782) is an essential replacement and upgrade component for serious RC enthusiasts in the UK who demand reliability and performance from their high-end RC models. This differential gear set is specifically engineered for Traxxas's most powerful and capable machines, including the legendary X-Maxx brushless monster truck and the extreme XRT performance platform. Whether you're a competitive racer pushing your brushless RC car to its limits, a weekend basher tackling rough terrain, or an experienced hobbyist maintaining your fleet, this genuine Traxxas differential gear set delivers the precision engineering and durability you need to keep your RC vehicle performing at peak efficiency.
Differential gears are critical components in any high-performance RC car, truck, or buggy. They allow the drive wheels to rotate at different speeds when cornering, which is essential for realistic handling, reduced tyre wear, and improved overall performance. The Traxxas TRX7782 gear set has been developed through extensive testing and real-world racing experience to ensure it meets the exacting standards demanded by the RC community. This is not a budget component—it's a precision-engineered differential system built to withstand the punishing forces generated by brushless motors and 8S LiPo batteries in high-powered RC vehicles.
When you choose the Traxxas Gear Set, Differential TRX7782, you're investing in genuine factory parts that maintain your vehicle's performance characteristics and warranty coverage. Counterfeit and aftermarket alternatives may offer a lower price, but they cannot match the precision tolerances, material quality, and performance consistency of authentic Traxxas components. For RC enthusiasts who take their hobby seriously and demand the best, this differential gear set is the only choice worth considering.
Key Features
- Complete Differential Assembly — This gear set includes everything needed to assemble or replace your differential, featuring two output gears and four spider gears that work together to distribute power smoothly to both drive wheels whilst allowing speed differentiation during cornering, which is essential for maintaining traction and control in any RC vehicle.
- Precision Engineering — Manufactured to exact Traxxas specifications using high-quality materials, these gears are engineered to mesh perfectly with minimal backlash and maximum efficiency, ensuring smooth power delivery and responsive handling that serious RC competitors and enthusiasts demand from their brushless RC trucks and buggies.
- Includes Thrust Washers — The set includes two 16x23.5x0.5mm thrust washers that maintain precise gear spacing and reduce friction between moving components, which extends the lifespan of your differential and ensures consistent performance even under extreme racing conditions with high-powered brushless motors and LiPo battery systems.
- Genuine Traxxas Component — As an original equipment manufacturer (OEM) part, this differential gear set is the exact component Traxxas installs in factory-built vehicles, guaranteeing compatibility, performance, and durability that matches the capabilities of your brushless RC car or monster truck.
- Wide Compatibility — Designed to work across multiple Traxxas platforms including the X-Maxx range, XRT competition truck, and Funco Motorsports sand car variants, this single gear set provides versatility for enthusiasts who maintain multiple RC vehicles.
Technical Performance
The Traxxas TRX7782 differential gear set represents the pinnacle of drivetrain engineering for high-performance RC vehicles. The combination of two precision-machined output gears and four spider gears creates a robust differential mechanism capable of handling the extreme torque loads generated by modern brushless motors operating on 8S LiPo battery systems. The included 16x23.5x0.5mm thrust washers are critical to differential performance, as they maintain precise axial spacing and minimise rotational friction, which translates to more efficient power delivery and less energy loss during acceleration and cornering. The gears are manufactured from hardened steel or equivalent high-strength materials that resist wear, stripping, and deformation even under the demanding conditions found in competitive racing or aggressive bashing. Whether you're running a Traxxas X-Maxx brushless monster truck capable of extreme speeds, tackling technical courses with an XRT, or exploring desert terrain with a Funco Motorsports platform, these gears are engineered to maintain perfect mesh alignment and smooth operation. The precision tolerances ensure minimal backlash, which directly improves steering response and overall vehicle handling characteristics. For UK RC enthusiasts who demand reliability and performance from their ready-to-run or race-ready vehicles, the engineering quality embedded in this differential gear set is uncompromising and professional-grade.

Frequently Asked Questions
- Which Traxxas RC vehicles is the TRX7782 differential gear set compatible with? — This genuine Traxxas differential gear set is compatible with a comprehensive range of high-performance Traxxas models including all X-Maxx Belted variants (available in red, green, orange, and blue), the X-Maxx Ultimate in both green and blue editions, the X-Monster chassis platform, all XRT VXL-8S models in multiple colours, the XRT Ultimate variants, and the Funco Motorsports Pro Scale 8S 2WD Electric Sand Car range, making it an essential spare part for anyone running these serious brushless RC vehicles.
- Is this suitable for beginners or only for experienced RC racers? — Whilst the TRX7782 is a genuine OEM Traxxas component, differential maintenance and replacement is typically an intermediate to advanced skill level task that requires mechanical knowledge and proper tools. If you're new to RC and need to replace your differential, we recommend consulting the detailed assembly instructions specific to your vehicle model or seeking guidance from experienced RC technicians at your local hobby shop.
- What is the difference between genuine Traxxas gears and aftermarket alternatives? — Genuine Traxxas components like the TRX7782 are engineered to exact factory specifications using premium materials and manufacturing tolerances that cannot be matched by aftermarket alternatives. Using genuine parts ensures perfect compatibility with your vehicle, maintains manufacturer warranty coverage, and guarantees the precision performance characteristics your brushless RC truck or buggy was designed to deliver, making genuine Traxxas parts the only sensible choice for serious enthusiasts.
- How often will I need to replace my differential gears? — The lifespan of differential gears depends heavily on driving style, maintenance practices, and the conditions in which you operate your RC vehicle. Casual bashers may go years between differential service, whilst competitive racers pushing their brushless machines hard might require more frequent inspection and potential replacement. Regular maintenance, including cleaning and occasional lubrication with quality RC differential fluid, can significantly extend gear life and maintain smooth, reliable performance.
- Does the TRX7782 gear set include everything I need to rebuild my differential? — The TRX7782 includes the essential gears and thrust washers required for the differential assembly, however complete differential rebuild kits typically include additional components such as output yokes, seals, and hardware. Check your vehicle's service manual to confirm whether you need additional components beyond this gear set for a complete differential overhaul.
