Key Features

• High-Performance Centre Differential Design — The differential absorbs driveline shocks that occur during acceleration, braking and cornering, which dramatically improves the overall durability of your drivetrain by reducing stress on gears, bearings and suspension components. This shock absorption means your RC car UK will last longer between maintenance sessions and handle more aggressive driving styles.
• Finned Aluminium Housing — The cooling fins machined into the aluminium carrier actively dissipate heat generated during operation, which is critical for maintaining differential fluid viscosity and preventing performance degradation during extended running sessions. Better heat dissipation means more consistent performance lap after lap, particularly important for competitive racing or intensive bashers' sessions.
• 44-Tooth Mod 1 Steel Spur Gear — The tough 44-tooth steel spur gear with mod 1 (1.0 metric pitch) specification provides maximum durability and wear resistance, ensuring reliable power transmission even under extreme driving conditions. The specific tooth count and metric pitch are engineered to work perfectly with the Maxx and Maxx Slash drivetrain, guaranteeing smooth, efficient power delivery.
• 20-Million Weight Silicone Oil Pre-Load — The differential arrives pre-loaded with heavy 20MM weight silicone oil, which is specifically formulated to prevent unloading and ballooning of the front tyres during hard acceleration. This heavy-weight oil maintains consistent differential action across all driving conditions, preventing the tyre roll that can occur with lighter fluids and compromising handling.
• Sealed Differential Construction — The sealed design protects internal components from dust, dirt and moisture, significantly extending the service life of the differential and reducing maintenance requirements. This sealed construction is essential for any serious RC enthusiast who wants reliability and longevity from their brushless RC truck.
• Complete Installation Package — This kit arrives as a complete assembly with all necessary components included, eliminating the need to source additional parts and ensuring straightforward installation for anyone with basic RC maintenance experience.

Technical Performance

The Traxxas centre differential represents cutting-edge RC drivetrain engineering, combining premium materials with precision manufacturing to deliver performance that serious RC competitors and dedicated bashers demand. The finned aluminium housing isn't merely an aesthetic choice — it's a critical thermal management component that actively dissipates the considerable heat generated when running a high-powered brushless RC truck at sustained high speeds or during intensive racing sessions. The 44-tooth steel spur gear is engineered to mod 1 specification (1.0 metric pitch), ensuring compatibility with the Maxx and Maxx Slash drivetrain whilst providing the durability required for competitive use. The sealed differential construction protects critical internal components from the elements, essential for any RC vehicle that will see outdoor use on UK tracks or rough terrain. The heavy 20-million weight silicone oil pre-load is the key to preventing tyre ballooning — a common issue in 4WD vehicles during hard acceleration where the differential unloads and allows excessive front tyre roll. This engineering approach maintains consistent differential lock characteristics across all driving conditions, preserving the vehicle's handling characteristics whether you're making smooth corner entries or launching hard off the line. For 1/8 scale 4WD short course trucks like the Maxx and Maxx Slash, the centre differential is absolutely critical to converting the power from your brushless motor system into controlled, predictable acceleration without sacrificing durability or handling.

Frequently Asked Questions

• What is a centre differential and why do I need one in my 4WD RC truck? — The centre differential is the component that distributes engine power between the front and rear axles whilst managing the speed difference between them during turning. It's essential in any 4WD RC vehicle because without it, the drivetrain would bind up during cornering, causing poor handling and potential mechanical failure. Upgrading to a high-performance centre differential like this Traxxas kit improves durability, handling and prevents tyre ballooning — a common issue where front tyres excessively roll during hard acceleration because the differential unloads.
• Is this suitable for beginners? — This is an accessory upgrade component rather than a standalone product, so it's best suited to intermediate or advanced RC enthusiasts who already own a compatible Maxx or Maxx Slash model and have basic RC maintenance experience. Installation requires some mechanical aptitude, though it's certainly within the capability of anyone with fundamental RC knowledge. If you're completely new to RC, you'd be better served purchasing a ready-to-run brushless RC truck first before upgrading components.
• What does the 20-million weight oil actually do? — The heavy 20MM weight silicone oil is specifically formulated to maintain viscosity and differential action across a wide range of driving conditions. Its primary function is preventing tyre ballooning by keeping the differential locked during acceleration, which prevents the front tyres from rolling excessively. Heavier weight oils are generally used for more aggressive driving styles and competitive use, whilst lighter weights might be used for gentler driving. This heavy pre-load makes this kit ideal for serious racers and bashers.
• Will this fit my existing Maxx or Maxx Slash? — Yes, this centre differential is explicitly designed for both the Traxxas Maxx and Traxxas Maxx Slash 1/8 scale short course truck models, as well as the WideMaxx monster truck variant. It's a direct replacement for the centre differential in these vehicles, making installation straightforward for anyone familiar with basic RC truck maintenance. Always verify your specific model variant before ordering to ensure compatibility.
• How long does this differential last before needing replacement? — With proper maintenance and appropriate driving, the sealed differential should provide many hours of reliable service. The steel spur gear and aluminium housing are engineered for durability, and the sealed construction protects internal components from wear. However, like all drivetrain components, it will eventually wear with use. Regular maintenance, including occasional differential fluid changes, will extend service life considerably.
• Can I change the differential fluid myself? — Yes, the sealed differential can be disassembled and the fluid replaced by anyone with intermediate RC maintenance experience and the appropriate tools. However, many users simply replace the entire differential unit rather than servicing it, particularly after heavy use or racing seasons. The pre-loaded design means you won't need to source and measure differential fluid if you replace the entire unit.
