Overview
The Traxxas Ring Differential / Pinion Gear Differential TRX7079 is an essential replacement drivetrain component designed for a range of popular Traxxas 1/16 scale RC models. Whether you're a serious RC enthusiast in the UK looking to maintain your vehicle or a hobbyist seeking quality spare parts, this genuine Traxxas differential assembly ensures your RC car performs at its best. This is a critical component that directly affects how power is distributed to your wheels, making it vital for both performance and longevity of your ready to run RC vehicle.
Compatible with multiple Traxxas models including the E-Revo VXL 1:16, Slash 1:16, Rally, and Summit platforms, the TRX7079 ring and pinion gear differential is engineered to handle the demands of high-performance RC driving. As an authorised Traxxas spare part, this component meets the exact specifications required by your RC car, ensuring seamless integration and reliable performance whether you're bashing casually or pushing your vehicle hard on the track.
Many RC drivers discover that upgrading or replacing the differential with quality OEM parts is one of the most effective ways to improve drivetrain reliability and handling characteristics. The Traxxas Ring Differential represents a genuine factory solution that maintains the integrity of your vehicle's power delivery system, allowing you to focus on the driving experience rather than worrying about component failure.
Key Features
- Genuine Traxxas OEM Component — This is an authentic factory-manufactured part, not an aftermarket clone or counterfeit, which guarantees compatibility and reliability with your specific Traxxas RC model and ensures you're getting the exact engineering specifications Traxxas designed for your vehicle.
- Rear Differential Ring and Pinion Gear Assembly — The complete ring and pinion gear set works together to distribute engine torque smoothly to the rear wheels, which is essential for smooth acceleration, consistent handling and predictable driving dynamics during both casual bashing and competitive driving.
- Wide Model Compatibility — Engineered to fit Traxxas E-Revo VXL (both blue and purple variants), Traxxas Slash 1:16, Traxxas Rally and Traxxas Summit platforms, making this a versatile spare part for owners of multiple Traxxas 1/16 scale vehicles or those looking ahead to future upgrades.
- Critical Drivetrain Component — As part of the differential system, this assembly is fundamental to how your RC car transfers power from the motor through the transmission to the wheels, directly influencing acceleration, turning behaviour and overall drivetrain longevity.
- Direct Replacement Part — Designed as an exact factory replacement, this part integrates seamlessly with your existing Traxxas drivetrain without requiring modifications, adapter plates or workarounds, meaning a straightforward installation process.
- OEM Quality Assurance — Being manufactured to Traxxas factory specifications ensures this differential meets the same rigorous quality standards as the original equipment installed in new vehicles, providing confidence in durability and performance.
Technical Performance
The Traxxas TRX7079 Ring Differential / Pinion Gear Differential represents precision-engineered drivetrain hardware designed specifically for 1/16 scale RC vehicles. The ring and pinion gears work in concert to create a differential that smoothly distributes rotational force from the motor to both rear wheels whilst allowing them to rotate at different speeds during cornering—a critical function for maintaining traction and handling characteristics on any terrain. The differential system is fundamental to how your RC car accelerates, corners and maintains stability during aggressive driving. Owner feedback indicates that whilst this is a genuine Traxxas part, the material composition of this component has been subject to discussion within the RC enthusiast community, with some users reporting that the gears can be prone to wear or damage under extreme conditions, particularly during high-power driving with upgraded motors or aggressive bashing. This is valuable information for buyers planning extended driving sessions or those using high-torque setups—consideration should be given to differential oil selection and shimming practices to optimise longevity. Installation requires mechanical aptitude and proper tools to remove and reinstall the differential correctly. As with most RC drivetrain work, applying quality differential oil is highly recommended to reduce friction and extend component life, and many experienced users recommend taking time to shim the differential properly during installation to prevent premature failure and optimise performance characteristics across different driving styles.
What's in the Box
- Traxxas Ring Differential / Pinion Gear Differential assembly (TRX7079)
What You Need to Complete

Frequently Asked Questions
- Is the Traxxas TRX7079 differential suitable for beginners? — This is a replacement spare part rather than a complete ready to run RC car, so it's designed for users who already have a compatible Traxxas 1/16 vehicle and understand basic RC maintenance. Installation requires some mechanical knowledge and proper tools. Beginners might want to seek guidance from experienced RC enthusiasts or a local hobby shop when installing this component.
- What Traxxas models does the TRX7079 fit? — This differential is specifically engineered for 1/16 scale Traxxas vehicles including the E-Revo VXL 1:16 (both blue X and purple variants), the Slash 1:16 4x4, the Rally and the Summit. Always verify your specific model number before ordering to ensure compatibility.
- How long does a differential last on an RC car? — The lifespan of an RC differential depends heavily on driving style, power levels, maintenance and component quality. Owner experiences with the TRX7079 vary, with some reporting reliable performance whilst others note that the gears can wear relatively quickly under heavy use or high-power setups. Regular maintenance including differential oil changes and proper shimming can significantly extend component life.
- Do I need differential oil with this part? — Yes, using quality differential oil is highly recommended. Differential oil reduces friction between the gears, helps dissipate heat and significantly extends the working life of the component. Many experienced RC users have found that proper lubrication prevents the premature wear that some owners have reported with this part.
- Why are some owners reporting issues with durability? — User reviews indicate that some drivers have experienced gear wear or breakage, particularly during aggressive driving or with high-torque motor setups. This suggests the material composition may have limitations under extreme conditions. Proper differential oil selection, correct shimming during installation and avoiding excessive power levels can help mitigate these issues.
- What is differential shimming and do I need it? — Shimming is the process of using thin spacers to adjust the clearance and preload in the differential assembly. Correct shimming optimises gear mesh, reduces backlash and helps prevent premature failure. Many experienced RC builders recommend shimming the differential properly when installing this component to prevent the issues some owners have reported.
- Can I upgrade to a stronger differential? — Yes, aftermarket differentials with different gear ratios, locking mechanisms or stronger materials are available from various RC manufacturers. However, if you want factory Traxxas performance and compatibility, the TRX7079 is the correct choice. If durability is a concern for your driving style, researching upgraded differential options might be worthwhile.
