Overview
The Traxxas Main diff with Steel ring gear (TRX2381X) is an essential drivetrain spare part designed for serious RC enthusiasts who demand durability and performance from their Traxxas RC vehicles. This high-quality differential assembly features a machined steel ring gear, side cover plate, and all necessary mounting screws, making it the perfect replacement or upgrade for Traxxas Bandit, Stampede, and Rustler models. Whether you're a competitive racer pushing your RC car to its limits or a weekend basher enjoying high-speed runs at your local track, this differential component delivers the strength and reliability you need to keep your vehicle performing at its peak.
Traxxas differentials are engineered to handle the extreme forces generated during acceleration, cornering, and high-speed manoeuvres that modern RC buggies and stadium trucks endure. The main differential is one of the most critical components in your RC car's drivetrain, responsible for distributing power to both drive wheels while allowing them to rotate at different speeds during turns. This particular assembly utilises a machined steel ring gear, which offers superior durability compared to standard plastic alternatives, ensuring your vehicle maintains consistent performance even under demanding conditions on the track or off-road terrain.
Available from RC Model Shop, a trusted UK RC retailer, the TRX2381X is an authentic Traxxas spare part backed by genuine warranty and support. This is the ideal choice for RC car owners in the UK who need a reliable replacement differential assembly for their Traxxas 2WD stadium truck or off-road vehicle, whether you're upgrading to stronger components or replacing worn parts after extensive use.
Key Features
- Machined Steel Ring Gear — This differential features a machined steel ring gear rather than a plastic alternative, providing exceptional hardness, wear resistance, and longevity under the stresses of high-performance driving, aggressive launching, and extended use on rough terrain.
- Complete Assembly Package — The kit includes the main differential body with the integrated steel ring gear, side cover plate, and all mounting screws needed for installation, eliminating the need to source components separately.
- OEM Quality and Compatibility — As a genuine Traxxas original equipment component, this differential is manufactured to exact specifications and guaranteed to fit Traxxas Bandit, Stampede, and Rustler models perfectly, ensuring proper meshing and optimal drivetrain performance.
- Enhanced Durability — The machined steel construction delivers greater strength than stock differentials, making this an excellent upgrade for drivers who frequently experience hard launches, perform jump sessions, or run at maximum throttle across varied terrain.
- Direct Replacement Design — The component integrates seamlessly with your existing Traxxas RC vehicle's drivetrain, requiring no modifications or additional parts for installation, making it suitable for both experienced builders and those new to RC maintenance.
Technical Performance
The Traxxas Main diff with Steel ring gear represents a significant enhancement to your RC vehicle's drivetrain performance and longevity. Manufactured from machined steel billet, this differential assembly offers superior hardness and precision compared to standard components, delivering the ultimate in drivetrain strength for the most demanding drivers. The steel ring gear is specifically engineered to resist wear and deformation during the intense stresses of high-speed running, supercross-style jumping, and aggressive off-road driving through rough terrain. The side cover plate ensures proper sealing and retention of differential fluid, maintaining consistent gear action and performance across multiple driving sessions. The complete assembly includes all necessary fasteners for secure installation, and the differential's ring gear can be removed and reinstalled without requiring you to empty the differential completely, providing convenient maintenance and the flexibility to adjust differential oil viscosity if desired. Traxxas offers differential oil kits with multiple weight options (such as 10,000, 30,000, and 50,000 weight silicone fluid) to allow drivers to fine-tune diff action and handling characteristics based on their specific driving style and track conditions.
