Key Features
- 37-Tooth Ring Gear — The primary large gear that engages with the pinion to transfer power through the differential, delivering smooth and reliable torque distribution to your RC vehicle's wheels during acceleration, braking and cornering manoeuvres.
- 13-Tooth Pinion Gear — This smaller precision-engineered gear drives the ring gear with optimal tooth engagement, ensuring minimal backlash and maximum efficiency in power transfer for responsive handling and consistent performance across varied terrain.
- Complete Differential Carrier Assembly — The full differential carrier is included, providing the mounting structure and support for the gear assembly within your RC vehicle's drivetrain, ensuring proper alignment and stable operation during intense driving sessions.
- PTFE-Coated Washer — The included 6x10x0.5mm PTFE-coated washer reduces friction and wear in the drivetrain, extending component lifespan and maintaining smooth operation even during extended driving sessions or competitive racing on UK RC tracks.
- Stainless Steel Hardware — Four 2x8mm countersunk machine screws are included for secure assembly and disassembly, providing corrosion resistance and reliable fastening that withstands the vibrations and stresses of off-road RC driving and racing.
- Genuine Traxxas Manufacturing — This is an authentic OEM Traxxas component manufactured to strict quality standards, ensuring perfect compatibility with your Traxxas RC model and delivering the performance characteristics Traxxas vehicles are known for throughout the RC community.
- Easy Installation — The complete assembly with all necessary hardware included makes replacement straightforward for experienced RC hobbyists, reducing downtime between driving sessions and allowing quick maintenance and upgrades to your RC setup.
Technical Performance
The Traxxas Ring 37-T / 13-T Pinion Gear and differential carrier assembly represents precision engineering at its finest, incorporating years of Traxxas development and real-world testing to deliver reliable performance in demanding RC applications. The 37-tooth ring gear and 13-tooth pinion combination provides an optimal gear ratio that balances acceleration response with top-end speed capability, making this setup suitable for a wide variety of Traxxas RC vehicles from crawlers to high-speed buggies and trucks. The PTFE (polytetrafluoroethylene) coating on the included washer is specifically engineered to reduce friction and wear during operation, a critical feature that extends the service life of your differential assembly and maintains consistent handling characteristics over hundreds of hours of driving. The differential carrier housing is manufactured to Traxxas' exacting standards using robust materials selected for durability under the intense stresses of RC bashers and competitive racing. The four countersunk machine screws provided (2x8mm specification) ensure secure fastening that distributes load evenly across the assembly, preventing loosening during aggressive driving or high-impact landings. This complete assembly approach means you receive everything needed for a professional-level repair or upgrade, with no guesswork about compatibility or missing components. Whether you're rebuilding after normal wear, upgrading for improved performance, or maintaining your RC car UK setup, this genuine Traxxas component delivers the reliability and precision engineering that keeps serious RC enthusiasts coming back to Traxxas.

Frequently Asked Questions
- What vehicles is the Traxxas TRX4981 ring and pinion gear compatible with? — The Traxxas Ring 37-T / 13-T Pinion Gear assembly is designed for use with Traxxas RC vehicles featuring compatible differential systems. You should verify your specific vehicle model before ordering to ensure compatibility, as different Traxxas models may require different gear ratios and carrier designs. Contact RC Model Shop's expert team if you're unsure whether this assembly is correct for your RC car or truck.
- How often should I replace my ring and pinion gears? — Ring and pinion gears typically require replacement after extensive use, usually measured in dozens of hours of driving depending on driving intensity, terrain conditions, and maintenance practices. Signs of wear include grinding noises from the differential, difficulty in smooth acceleration, or visible tooth damage visible during inspection. Regular maintenance and inspecting your drivetrain components keeps your RC vehicle performing optimally and helps identify wear before catastrophic failure occurs.
- What does the PTFE washer do? — The PTFE-coated washer reduces friction between moving components in the differential assembly, which minimises heat generation, extends component lifespan, and maintains consistent performance throughout your RC vehicle's operation. PTFE (Teflon) is a low-friction material widely recognised in mechanical engineering for improving efficiency and durability in precision applications like RC drivetrains.
- Can I install this myself? — This component requires disassembly of your RC vehicle's differential, which demands mechanical skill, proper tools, and understanding of drivetrain assembly procedures. Experienced RC hobbyists with mechanical background and proper workshop facilities can handle installation, but if you're new to RC maintenance, we recommend visiting RC Model Shop in person or consulting detailed vehicle-specific guides before attempting installation yourself.
- Why is genuine Traxxas the right choice? — Genuine OEM Traxxas parts guarantee perfect compatibility with your Traxxas RC vehicle and meet the manufacturer's quality standards developed through years of testing and real-world competition use. Genuine parts provide better fit, longer lifespan, and superior performance compared to aftermarket alternatives, ensuring your RC investment continues delivering the handling and reliability you expect.
