Overview
The Traxxas Housing, centre Differential / x-ring gaskets (2 pcs) / ring gear gasket / bushings (2 pcs) / 5x10x0.5 TW (2 pcs) / CCS 2.5x8 (4 pcs) TRX6884 is an essential replacement part for serious RC enthusiasts maintaining their Traxxas vehicles. This complete centre differential housing assembly is specifically designed as a replacement for the 6814 centre differential, making it the perfect choice for anyone looking to restore their RC car's drivetrain to factory specifications or upgrade worn components. Whether you're a dedicated RC basher pushing your machine to the limits on UK tracks and terrain, or a weekend hobbyist keen to keep your ready to run RC car performing at its best, this genuine Traxxas spare part ensures your differential system functions smoothly and reliably.
Centre differential systems are critical to the performance of 4WD RC vehicles, allowing the front and rear axles to rotate at different speeds during cornering whilst maintaining traction and stability. When these components wear out or become damaged through regular use, replacing them with quality OEM parts like this housing assembly is far more cost-effective than replacing the entire differential unit. The TRX6884 comes complete with all the gaskets, bushings and fasteners you need, saving you time hunting down individual components and ensuring perfect compatibility with your Traxxas vehicle.
RC Model Shop stocks this genuine Traxxas spare part as part of our comprehensive range of drivetrain components for brushless RC cars, electric RC buggies, short course trucks and other Traxxas models. If you're serious about maintaining your RC vehicle UK-wide, choosing authentic replacement parts like the TRX6884 is the smart decision that keeps your machine running like new.

Technical Performance
The Traxxas centre differential housing assembly represents precision engineering at its finest, manufactured to the exact specifications demanded by high-performance RC vehicles. The housing itself provides the structural framework for the differential mechanism, whilst the included gaskets and seals maintain the integrity of the lubrication system essential for smooth gear operation. The X-ring gaskets offer superior sealing performance compared to standard gasket materials, with their unique shape providing multiple contact points that prevent oil weeping even under high rotational speeds and lateral forces experienced during aggressive driving. The bushings are manufactured from durable polymer materials that reduce friction whilst maintaining dimensional stability, crucial for maintaining the precise tolerances required in a differential assembly. The included fasteners are manufactured from stainless steel or equivalent corrosion-resistant material, designed to hold securely under the constant torque and vibration of high-performance RC driving. This complete assembly is engineered to work seamlessly with all compatible Traxxas 4WD vehicles, maintaining the factory differential characteristics that ensure balanced handling, predictable cornering and optimal weight distribution across all four wheels. The precision fit of all components ensures that when installed correctly, your RC car's centre differential will operate with the same smooth, reliable performance as when the vehicle left the factory.

Frequently Asked Questions
- Which Traxxas RC cars is the TRX6884 centre differential housing compatible with? — The TRX6884 is a direct replacement housing for the 6814 centre differential and is compatible with several popular Traxxas models including the Ford Fiesta ST Rally BL-2S in red, the Ford Fiesta ST Rally VXL in green, Slash 4X4 BL-2S models with Fox and green variants, and the Slash Ultimate 4x4 VXL in orange. It fits any Traxxas vehicle that uses the 6814 centre differential, so check your vehicle's parts diagram to confirm compatibility before ordering.
- Do I need any additional tools or parts to install this centre differential housing? — The TRX6884 includes all the gaskets, bushings and fasteners required for installation, so you won't need to source additional components separately. You will need basic RC hobby tools such as hex drivers to remove the old housing and install the new one, along with a small amount of quality RC differential fluid to lubricate the gears. Check your vehicle's manual for the specific type of differential fluid recommended by Traxxas.
- How often should I replace my centre differential housing? — Under normal RC hobby conditions, a centre differential housing should last thousands of miles of driving. However, if you've had a serious crash that damaged the housing, notice oil leaking from the differential, or experience grinding noises from the centre diff, it's time to replace it. Regular maintenance including periodic inspection and fluid changes will extend the life of your differential housing significantly.
- What is the difference between this housing and aftermarket alternatives? — The TRX6884 is a genuine Traxxas OEM part engineered to factory specifications, ensuring perfect fit and performance. Aftermarket housings may have slightly different dimensions or material compositions that can affect fitment, sealing quality and overall differential performance. For critical components like the centre differential, genuine parts are always the recommended choice for reliability and longevity.
- Is this suitable for beginners? — Whilst the TRX6884 is a genuine spare part suitable for all skill levels, centre differential housing replacement is an intermediate-level maintenance task. If you're new to RC car maintenance, you may want to consult your vehicle's service manual or seek guidance from experienced RC enthusiasts before attempting installation. Many UK RC clubs and local hobby shops offer guidance for maintenance tasks.
- How do I know if my centre differential housing needs replacing? — Signs that your housing may need replacement include visible cracks or damage to the housing itself, oil leaking from the differential area, grinding or clicking noises when turning, or poor traction and handling that suggests differential problems. A visual inspection of your vehicle after crashes or extended use is always recommended.
