- X-Ring Gaskets — The two x-ring gaskets provide superior sealing compared to standard O-rings, keeping dirt, dust and moisture out of your differential assembly while maintaining pressure and oil integrity during high-performance driving sessions.

Technical Performance
The centre differential housing is a critical component in any RC car UK setup that uses Traxxas's proven differential technology. The aluminium construction offers significant advantages over plastic alternatives: it dissipates heat more effectively during extended driving sessions, resists impact damage from jumps and crashes, and maintains dimensional accuracy over thousands of operating cycles. The engineering behind this component reflects Traxxas's commitment to quality—every feature, from the precision-machined housing to the PTFE-coated washers, has been designed to work in harmony. When your RC car is performing at its best, the centre differential is working silently in the background, distributing torque between the front and rear axles with the smoothness and efficiency this aluminium housing provides. The included x-ring gaskets represent a significant upgrade in sealing technology, preventing fluid loss and contamination that could compromise differential performance. Whether you're running a brushless RC car UK at high speeds or putting your RC vehicle through challenging terrain, this housing maintains the precise tolerances that Traxxas is recognised for in the RC community worldwide.

Frequently Asked Questions
- Is this a genuine Traxxas part or an aftermarket replacement? — This is a genuine Traxxas component manufactured to OEM specifications. Traxxas parts are engineered to integrate seamlessly with your RC car UK without compatibility issues, and they carry the reliability that Traxxas is recognised for across the RC hobby community.
- What models is the TRX6781 centre differential housing compatible with? — This housing is designed as a direct replacement for Traxxas models that use the 6780 centre differential assembly. Check your vehicle's documentation or contact our team to confirm compatibility with your specific RC car UK model before ordering.
- Why should I upgrade from the plastic housing to this aluminium version? — Aluminium offers superior durability, better heat dissipation, and greater impact resistance compared to plastic housings. For RC enthusiasts who bash regularly or race competitively, the aluminium housing reduces the risk of housing failure and maintains consistent differential performance over extended use, making it a worthwhile investment for any serious RC car UK setup.
- What are PTFE-coated washers and why do they matter? — PTFE (polytetrafluoroethylene) coating reduces friction between metal components, which means less wear on your differential assembly and smoother power transfer to your wheels. This coating helps your centre differential operate more efficiently and extends the service life of the entire assembly, especially important if you run your RC car frequently.
- Do I need any tools to install this centre differential housing? — Installation requires basic RC car UK maintenance tools including hex drivers and possibly a small screwdriver for the CCS screws. If you're familiar with RC car maintenance and have replaced components before, this is a straightforward installation. If you're unsure, our experienced team at RC Model Shop can provide guidance or assistance.
- Is this suitable for both brushless and brushed RC cars? — Yes, the centre differential is a mechanical component that works independently of your motor system, whether you're running a brushless or brushed RC car UK. This housing will function identically regardless of your powertrain configuration.
- How often should I replace my centre differential housing? — With proper maintenance and the durability of this aluminium construction, the housing itself should last thousands of operating cycles. However, if your housing becomes damaged from crashes, impact, or if seals fail allowing contamination, replacement becomes necessary to maintain optimal differential performance.
