VITAVON Center Full Diff Case Set 31MM For Arrma 6S BLX Mojave Silver, Black Kraton Outcast 1:8 - Vitavon VITARA310989

Overview

The VITAVON Center Full Diff Case Set 31MM is a precision-engineered upgrade component designed specifically for high-performance 1/8 scale Arrma 6S brushless RC buggies and trucks. This premium differential case assembly is built from aerospace-grade Alu7075 aluminium and hardened steel 45# materials, making it an essential choice for UK RC enthusiasts who demand reliability and durability in their bashers and racers. Whether you own an Arrma Mojave, Kraton, Outcast, Typhon, Fireteam or Limitless model, this centre differential upgrade will significantly enhance the handling characteristics and longevity of your RC car UK setup.

Differential cases are critical components in any serious RC vehicle, controlling how power is distributed to the wheels during cornering and straight-line acceleration. A quality centre diff case like this one from VITAVON makes the difference between a truck that handles unpredictably and one that provides confidence-inspiring, controllable performance across all driving conditions. The 31mm case size is specifically engineered to fit within the centre bulkhead of your Arrma 6S model, ensuring perfect compatibility without modifications to your existing setup.

This is not a basic plug-and-play component—it is a serious upgrade for anyone running an RC car UK-based or anywhere else who wants to improve differential performance. The inclusion of a 50T spur gear means this unit is ready to work seamlessly with your vehicle's drivetrain. If you are committed to getting the best handling and longevity from your Arrma 6S brushless RC truck or buggy, this VITAVON centre diff case set represents outstanding value and engineering quality.

Key Features

• Aerospace-Grade Alu7075 Construction — The main diff case housing is machined from 7075 aluminium alloy, one of the strongest aluminium alloys available, which provides exceptional rigidity and resistance to impact damage whilst remaining lightweight compared to steel alternatives, making it ideal for high-speed bashing and competitive racing.
• Hardened Steel 45# Internal Components — Critical internal gears and components are manufactured from hardened steel grade 45#, which dramatically extends the lifespan of the differential under heavy load and repeated stress, ensuring that your investment remains functional through countless bashing sessions and race days.
• 31MM Full Diff Case Design — This is a complete differential case assembly with a 31mm diameter, sized precisely for centre bulkhead installation on Arrma 6S models; the full diff design means you get the complete sealed unit rather than partial upgrades, delivering superior protection against dust and moisture ingress.
• Included 50T Spur Gear — The 50-tooth spur gear comes pre-fitted with this set, ensuring your drivetrain is immediately functional upon installation without the need for additional purchases, and the 50T ratio is engineered to provide optimal acceleration and torque characteristics for 6S brushless RC models.
• Centre Bulkhead Compatibility — This assembly is specifically designed to replace the factory centre differential and integrate directly with your vehicle's centre bulkhead, meaning installation is straightforward for anyone with basic RC maintenance skills and a standard hex key set.
• Multi-Vehicle Compatibility — The 31mm case is compatible with a wide range of Arrma 6S BLX models, including the Mojave 6S, Kraton 6S, Outcast, Typhon, Notorious, Fireteam and Limitless, making this a versatile upgrade if you run multiple vehicles from the Arrma 6S platform.

Technical Performance

The VITAVON Center Full Diff Case Set represents a significant engineering upgrade over standard factory differential cases found on ready-to-run RC cars UK. The combination of 7075 aluminium and HD steel 45# materials creates a hybrid structure that balances weight savings with exceptional durability. The 31mm case diameter is the industry standard for 1/8 scale centre differentials, and VITAVON has engineered this unit to withstand the extreme stresses generated by modern brushless 6S LiPo powerplants that deliver over 2000 watts of power. The full diff case design incorporates sealed bearings and precision-machined gears, significantly reducing wear compared to open-style differential designs. The integrated 50T spur gear means the gear ratio is optimised for the electrical characteristics of modern brushless motors, providing the perfect balance between acceleration and top speed for typical 6S setups. This is not decorative—every aspect of this component is engineered for performance RC vehicles that see serious use on rough terrain, at speed, in competitive environments. Installation involves removing the factory centre bulkhead and replacing it with this upgraded assembly, a task well within the capabilities of any RC hobbyist with basic mechanical knowledge. The precision tolerances maintained throughout manufacturing ensure that gear mesh and bearing preload are correct from the moment of installation, with no tedious adjustments required.

Frequently Asked Questions

• Will this centre diff case fit my Arrma 6S model? — Yes, this 31MM centre diff case is specifically designed for Arrma 6S BLX models including the Mojave 6S, Kraton 6S, Outcast, Typhon, Notorious, Fireteam and Limitless. The unit replaces the factory centre differential and installs directly into your centre bulkhead, though you should verify your specific model variant before ordering to ensure compatibility with your exact revision.
• What makes this upgrade better than the factory differential? — The factory differential in most Arrma 6S models uses plastic-heavy construction to reduce weight, which sacrifices durability during high-impact bashing and racing. This VITAVON unit uses aerospace-grade 7075 aluminium and hardened steel 45#, dramatically increasing resistance to wear, impact damage and gear stripping. The sealed design also protects internal components from dirt and moisture, extending the life of the differential and maintaining consistent performance over time.
• Is installation difficult? — Installation is straightforward for anyone comfortable performing basic RC maintenance. You will need to remove your factory centre bulkhead, which typically requires unbolt the transmission and driveshafts, then install the VITAVON unit in its place. Most UK RC enthusiasts can complete this upgrade in under an hour with standard hex keys and screwdrivers. If you are uncertain, you can contact the RC Model Shop team for installation guidance.
• What is the benefit of the 50T spur gear included with this kit? — The 50-tooth spur gear is optimised for brushless 6S LiPo setups, providing the ideal balance between acceleration and top speed. Rather than purchasing this component separately, having it included saves money and ensures the gear ratio is correct from the moment of installation. The 50T is a popular choice for both racing and bashing applications with 6S brushless power.
• Will this improve my RC car's handling? — A quality centre differential case directly impacts how your RC vehicle distributes power to the wheels during cornering and acceleration. The sealed, precise engineering of this VITAVON unit means power delivery is more consistent and controllable than worn or plastic factory differentials, resulting in more predictable handling and easier driving characteristics, particularly during high-speed corners and rapid acceleration.
• Is this suitable for beginners? — This product is an upgrade component, not a complete vehicle, so it is best suited to RC enthusiasts who already own a compatible Arrma 6S model and have basic mechanical skills. Beginners new to RC should start with a complete ready-to-run RC car UK package, then consider upgrades like this centre diff case once they are comfortable with basic maintenance and have identified the need for improved durability.
• What is the difference between this 31MM case and other differential sizes? — The 31MM size is specifically engineered for Arrma 6S centre bulkhead applications. Other manufacturers offer 29MM cases for different models, but the 31MM is required for the models listed above. Using the correct size ensures proper fitment, correct gear mesh and reliable performance without modifications.
