Traxxas Differential Gear Set Planetary Output Gears Spider Gears TRX10782

Overview

The Traxxas Gear Set, differential (planetary) is an essential replacement component for owners of Traxxas mini-scale RC vehicles including the Mini Maxx, Mini XRT, Mini Slash, and Mini Rally models. This genuine Traxxas part (TRX10782) is designed to restore your RC car's drivetrain performance when the original differential gears have worn out or sustained damage from aggressive driving. Whether you're a dedicated basher pushing your RC car to its limits on UK tracks and backyard terrain, or a weekend enthusiast who demands reliability from their RC hobby investment, having a quality replacement differential gear set on hand ensures minimal downtime and maximum enjoyment of your RC experience.

The differential is one of the most critical components in any RC car's transmission system, responsible for distributing power between the wheels whilst allowing them to rotate at different speeds during cornering. A worn or damaged differential will noticeably affect handling, traction, and overall performance. This genuine Traxxas differential gear set gives you the confidence that you're installing factory-spec components that have been engineered and tested to work seamlessly with your specific RC vehicle model. RC car UK enthusiasts know that investing in genuine OEM parts like this ensures longevity and consistent performance, particularly if you race competitively or frequently run your RC car in demanding conditions.

Built to exacting Traxxas standards, this differential gear set represents the perfect solution for maintenance and repair of your mini-scale Traxxas models. The comprehensive package includes every component necessary to rebuild your differential quickly and efficiently, getting your RC car back in action with minimal fuss.

Key Features

• Genuine Traxxas OEM Component — This is the authentic factory part designed specifically for Traxxas mini-scale models, ensuring perfect fit, function and compatibility with zero fitment issues or performance compromises.
• Complete Differential Assembly Kit — The set includes all necessary components (output gears, spider gears, shafts, spacers and pins) in a single package, eliminating the need to source parts individually and ensuring you have everything required for a complete rebuild.
• Two Output Gears — The pair of precisely machined output gears transfers power from the differential case to the axle shafts, and this dual set ensures balanced torque distribution and smooth power delivery to both wheels.
• Four Spider Gears with Matching Shafts — These planetary-style gears enable the differential action that allows your wheels to rotate at different speeds during cornering, improving handling and reducing tyre scrub on tight RC tracks and technical terrain.
• Differential Spacers Included — Two spacer components maintain proper gear alignment and prevent excessive side-to-side movement within the differential case, critical for smooth operation and longevity of the assembly.
• Precision Pins for Secure Assembly — Two 2.5x8.25mm pins are included to lock the gear shafts in place, ensuring components remain perfectly positioned during operation even under the aggressive forces encountered during high-speed RC driving.
• Output Shaft Included — The complete output shaft is provided as part of the kit, eliminating the need for additional purchases and ensuring you have a complete solution for differential repair.
• Compatible with Multiple Traxxas Mini Models — This single gear set works with the Mini Maxx Monster Truck, Mini XRT, Mini Slash 4X4, and Mini Rally, making it a versatile spare part for collectors of Traxxas mini-scale vehicles.

Technical Performance

The Traxxas TRX10782 differential gear set is engineered with precision manufacturing standards that Traxxas is renowned for throughout the RC car hobby in the UK and globally. The planetary gear arrangement (also called spider gear configuration) uses four spider gears working in concert with two output gears to create a fully functioning open differential, the industry-standard design for RC vehicles that require balanced torque delivery and the ability for wheels to speed up and slow down independently during cornering. The machining tolerances are extremely tight, ensuring minimal backlash and smooth, quiet operation during both acceleration and deceleration. The complete kit includes all wear components and fasteners, meaning you're not purchasing a partial solution—everything needed for a full differential rebuild is included in the box. The 2.5x8.25mm retention pins are precision-engineered to maintain gear shaft positioning under the high rotational forces and shock loads encountered during aggressive RC car operation, whilst the differential spacers precisely control end-play and gear mesh depth. This attention to engineering detail is what separates genuine OEM Traxxas parts from inferior aftermarket alternatives, and explains why experienced RC enthusiasts across the UK consistently choose factory parts for critical drivetrain components.

Frequently Asked Questions

• Which Traxxas models does this differential gear set fit? — This genuine Traxxas part (TRX10782) is designed for and compatible with the Traxxas Mini Maxx Monster Truck, Mini XRT, Mini Slash 4X4, and Mini Rally VXL Ford RS200 models, making it an essential spare for collectors of these mini-scale Traxxas vehicles.
• Why would I need a replacement differential gear set for my RC car? — Differential gears experience constant wear during normal RC operation, and more aggressive wear under high-speed bashing, racing, or repeated heavy-load driving. If you notice your RC car pulling to one side, experiencing inconsistent traction during cornering, or hearing grinding noises from the drivetrain, the differential gears may be worn or damaged and require replacement to restore proper handling and performance.
• Is this difficult to install myself, or do I need professional help? — Differential assembly requires mechanical aptitude and the right tools, but is well within the capability of most RC enthusiasts with basic hobby experience. If you're unfamiliar with RC car maintenance, we recommend consulting your vehicle's manual or contacting our expert team at RC Model Shop for guidance, as improper assembly can lead to performance issues.
• Will this genuine Traxxas part perform better than aftermarket alternatives? — Yes, genuine OEM Traxxas parts are engineered to exact factory specifications and manufactured to the same tolerances as the components in your vehicle, ensuring perfect fit and reliable performance. Whilst some aftermarket options may be cheaper, they often feature inferior machining tolerances and materials that result in increased backlash, noise, and premature wear—investing in genuine parts protects your RC car investment.
• What is the difference between an open differential like this and a locked differential? — The planetary spider gear design in this differential allows each wheel to rotate independently, which improves handling on uneven terrain and reduces tyre scrub during cornering. A locked differential, by contrast, forces both wheels to rotate at identical speeds, which provides maximum traction in straight-line acceleration but reduces cornering finesse and can cause handling issues on technical tracks.
