Available at competitive prices from RC Model Shop, this is the perfect component for anyone serious about maintaining their RC car investment and ensuring optimal performance on track, trail, or terrain.
Built with Traxxas engineering excellence and quality control standards, this differential gear set represents the factory-standard solution that professionals and enthusiasts trust. The PTFE-coated washer ensures smooth operation and reduced friction, whilst the precision-machined gears guarantee longevity and consistent performance across countless runs and races.
Key Features
- 13-Tooth Output Gears (2 pieces) — The two 13-tooth output gears form the core of your differential system, transferring power from the driveshaft to the axles whilst allowing independent wheel rotation during cornering and acceleration, which is essential for maintaining grip and control through challenging sections of track or terrain.
- 13-Tooth Spider Gears (2 pieces) — These precision-engineered spider gears work in conjunction with the output gears to allow differential action, enabling your RC car to maintain traction whilst turning by allowing the outer wheel to rotate faster than the inner wheel, a critical feature for realistic and responsive handling.
- Spider Gear Shaft — The spider shaft is the central component that holds the spider gears in place and allows them to rotate freely, providing the mechanical foundation for the entire differential action and ensuring smooth, consistent performance during all driving conditions.
- 6x10x0.5mm PTFE-Coated Washer — This precision washer is coated with PTFE (polytetrafluoroethylene), a low-friction material that reduces wear and heat generation within the differential, ensuring smooth operation, extending the lifespan of all differential components, and maintaining consistent performance across multiple runs and competitive events.
- Genuine Traxxas Component — As an official Traxxas replacement part, this differential gear set meets all factory specifications and quality standards, ensuring perfect compatibility with compatible Traxxas models and providing the peace of mind that comes with using genuine manufacturer parts rather than aftermarket alternatives.
- Factory Precision Engineering — Every gear tooth, shaft, and washer is manufactured to exacting tolerances, ensuring smooth meshing, minimal backlash, and consistent power delivery that serious RC drivers depend on for competitive performance and reliable daily driving.
Technical Performance
The Traxxas Diff gear Set TRX4982 represents precision engineering at its finest, featuring carefully machined 13-tooth gears that provide an optimal balance between acceleration and top-end speed for most driving scenarios. The 13-tooth configuration is a popular choice across the Traxxas range, offering responsive handling characteristics without sacrificing top speed, making it equally suitable for track racing, off-road bashing, or competitive circuit driving. The PTFE-coated washer is a key engineering feature that demonstrates Traxxas's attention to detail; PTFE (polytetrafluoroethylene) is an extremely low-friction material that significantly reduces the heat generated within the differential during operation, preventing premature wear of the gear teeth and ensuring that performance remains consistent lap after lap, run after run. The spider gears are manufactured from hardened metal to withstand the tremendous forces experienced during acceleration, cornering, and deceleration, whilst the precision-ground shaft ensures true rotation and minimal radial play. When properly installed and maintained, this differential gear set will deliver thousands of hours of reliable service, making it one of the best investments you can make in keeping your RC car performing at its peak. The complete assembly ensures that you have everything needed for a professional-quality differential renewal, eliminating the need to source multiple components from different suppliers.

Frequently Asked Questions
- What does a differential do in an RC car and why do I need to replace the gears? — The differential is the component that allows your RC car's wheels to rotate at different speeds, which is essential for maintaining traction and control when cornering. Over time, through normal wear and tear from racing, bashing, or competitive use, the gears can become worn, stripped, or damaged, causing your car to lose grip, understeer, or experience inconsistent handling. Replacing the differential gears with this genuine Traxxas set restores your car to factory-specification performance and ensures smooth, predictable handling once again.
- Is this suitable for beginners or only experienced drivers? — This is a replacement component rather than a complete vehicle, so it's designed for RC enthusiasts who already own a compatible Traxxas model and understand basic maintenance and upgrades. If you're new to RC and unsure whether you need this part, contact our team at RC Model Shop for guidance; we can help you diagnose whether your differential needs replacement and advise on installation if needed.
- What does the PTFE coating on the washer do? — PTFE (polytetrafluoroethylene) is a low-friction material that reduces heat generation and wear within the differential system. This coating ensures smoother operation, extends the lifespan of all differential components, and maintains consistent performance across multiple runs and racing sessions, making it a critical feature for both competitive and recreational use.
- Which Traxxas models is this compatible with? — This genuine Traxxas differential gear set is designed for compatible Traxxas models; we recommend checking the part number TRX4982 against your specific model's manual or parts diagram to confirm compatibility before purchasing. If you're unsure, our experienced team at RC Model Shop can help you verify compatibility.
- How often should I replace my differential gears? — The frequency of replacement depends on how intensively you drive your RC car. Competitive racers may replace gears more frequently due to the extreme forces involved, whilst casual bashers might go much longer. The PTFE-coated design of this set helps extend the interval between replacements by reducing wear, but if you notice handling changes, grinding sounds, or loss of grip through corners, it's time to consider replacement.
- Can I install this myself or do I need professional help? — Differential installation requires some mechanical knowledge and the right tools, including a proper differential tool kit. If you're experienced with RC maintenance, you may be able to handle the installation yourself; however, if you're uncertain, we recommend consulting your vehicle's manual or seeking assistance from experienced RC technicians.
