Key Features
- Complete Centre Differential Housing Assembly — This is not just a simple housing; it's a complete assembly that includes all the gaskets and fasteners needed for installation, saving you money and ensuring you have everything required for a proper repair without ordering multiple parts separately.
- Two X-Ring Gaskets Included — The dual X-ring gaskets provide superior sealing compared to standard O-rings, preventing differential fluid leakage and maintaining optimal lubrication of internal components, which directly translates to longer component life and more reliable performance during driving.
- PTFE-Coated Washer — The 5x10x0.5 millimetre PTFE (polytetrafluoroethylene) coated washer reduces friction and wear between moving parts, ensuring smooth operation of the differential and minimising internal stress on precision components.
- Quality Fasteners Included — Four 2.5x8 CCS screws are provided with this assembly, which are precision-engineered fasteners that secure the housing with the exact torque specifications Traxxas engineers have determined for optimal performance and reliability.
- Genuine Traxxas Manufacturing — As an authorised Traxxas component, this centre differential housing meets all original equipment manufacturer specifications and quality standards, ensuring perfect compatibility and performance with your RC car.
- Compatible with Multiple Models — Designed to work with the entire Traxxas Mini Rally VXL Ford RS200 series including the standard model, grey variant, red variant, and blue variant, giving you peace of mind that this part will fit your specific RC car.
- Essential Maintenance Component — The centre differential is a high-wear component in any RC car's drivetrain; having a replacement on hand ensures you can quickly get back to driving without extended downtime waiting for parts to arrive.
Technical Performance
The centre differential is one of the most important components in any RC car's drivetrain system, responsible for distributing engine power between the front and rear axles while allowing them to rotate at different speeds during cornering. The TRX9081 housing has been engineered by Traxxas to withstand the demanding conditions RC cars experience during competitive racing, recreational bashing, and high-speed driving. The inclusion of two X-ring gaskets represents Traxxas's commitment to superior sealing technology; X-rings provide a better seal than traditional O-rings because their cross-section creates four contact points with the mating surfaces instead of two, dramatically reducing the risk of fluid leakage even under extreme conditions. The 5x10x0.5 millimetre PTFE-coated washer is a precision component that minimises friction between the housing and internal differential components, reducing heat generation and wear. The four 2.5x8 CCS fasteners are manufactured to exact specifications that ensure proper clamping force without over-tightening, which could damage the housing or strip threads. Built from materials selected for their durability and resistance to the stresses encountered in RC car competition, this housing will provide years of reliable service when properly maintained and installed according to Traxxas specifications. The precision manufacturing tolerances ensure perfect alignment of all internal components, which is critical for smooth operation and longevity. Whether you're running on tarmac circuits, dirt tracks, or mixed terrain, this centre differential housing delivers the reliability and performance you need.

Frequently Asked Questions
- What RC cars is the Traxxas TRX9081 centre differential housing compatible with? — The TRX9081 is designed specifically for the Traxxas Mini Rally VXL Ford RS200 series, which includes the standard TRX108046-1 model, the grey variant TRX108046-1-GRAY, the red variant TRX108046-1-RED, and the blue variant TRX108046-1-BLUE. Always verify your model number before purchasing to ensure compatibility.
- Do I need any additional parts to install this centre differential housing? — The TRX9081 comes as a complete assembly with all the gaskets and fasteners needed for installation. However, you will need differential fluid or oil to lubricate the internal components. Check your Traxxas manual or contact an RC specialist for the correct specification of differential fluid for your model.
- What is the difference between X-ring gaskets and standard O-ring gaskets? — X-ring gaskets provide superior sealing performance compared to standard O-rings. The X-shaped cross-section of an X-ring creates four contact points with the mating surfaces, providing a better seal at lower pressure and remaining effective even if there is slight surface wear or damage. This means your differential fluid stays where it should be, keeping internal components properly lubricated.
- How often should I replace the centre differential housing? — The centre differential housing itself is a durable component that can last many years with proper maintenance. However, the gaskets and seals inside can wear over time. If you notice differential fluid leakage, difficulty in differential operation, or if you're performing regular maintenance on your RC car, replacing the gasket and seal assembly is a cost-effective way to maintain optimal performance. Many RC enthusiasts replace these components annually if they race competitively.
- What does the PTFE coating on the washer do? — PTFE (polytetrafluoroethylene) is a low-friction material that reduces wear between moving parts. The coating on the 5x10x0.5 millimetre washer minimises friction between the housing and internal differential gears, reducing heat generation and extending the lifespan of internal components. This is especially important in high-performance RC cars where every fraction of efficiency matters.
- Is this suitable for beginners? — While this is a genuine spare part rather than a complete ready-to-run RC car, it is suitable for anyone with basic mechanical knowledge of RC cars. If you're a beginner and your differential housing needs replacement, it's recommended to consult your vehicle manual or seek guidance from an experienced RC technician to ensure correct installation. Alternatively, you can visit your local RC hobby shop for professional installation assistance.
- What should I do if my centre differential is leaking? — If you notice differential fluid leaking from your RC car, the cause is usually a failed seal or gasket. The TRX9081 housing assembly includes new X-ring gaskets and a PTFE-coated washer, which are the most common components that require replacement. Following Traxxas installation instructions, you can replace the housing assembly to resolve leaks. Always drain the old differential fluid before installation and refill with the correct specification fluid.
