Overview
The VITAVON Full Diff Case Set 31MM With 10/43T is a premium upgrade component designed specifically for ARRMA 6S BLX scale RC buggies and trucks. This is an essential upgrade for anyone running an ARRMA Mojave, Kraton, Outcast, Typhon or Limitless 1:8 scale RC car who demands maximum performance and durability from their differential system. Whether you're a competitive racer, weekend basher, or serious RC enthusiast in the UK looking to enhance your machine's handling and power delivery, this full differential case set represents a significant step up in quality and performance over stock components.
Built from premium materials combining CNC-machined aluminium 7075 and hardened steel, this 31mm full diff case set offers uncompromising strength, precision engineering and reliability. The VITAVON brand has established itself as a recognised manufacturer of high-quality CNC aftermarket parts for large-scale RC vehicles, and this differential case set exemplifies their commitment to excellence. With the 10/43T gear ratio configuration, this setup is optimised for balanced acceleration and top-end speed, making it suitable for a variety of driving conditions and styles. If you're serious about upgrading your brushless RC truck or buggy, this is exactly the kind of precision-engineered component that separates casual bashers from dedicated RC enthusiasts.
The full diff case design is engineered to distribute power evenly across both wheels whilst maintaining excellent cornering characteristics and forward traction. This makes it ideal for off-road driving where terrain variability demands responsive, predictable handling. The 31mm size is the proven standard for 1:8 scale ARRMA platforms, ensuring perfect fitment and optimal performance with your existing setup.
Key Features
- Premium CNC-Machined Aluminium 7075 Construction — The main diff case body is machined from aviation-grade aluminium 7075, which offers exceptional strength-to-weight ratio and superior durability compared to cheaper cast or plastic alternatives, meaning your investment will withstand years of aggressive driving without cracking or stripping gears.
- Hardened HD Steel Internal Components — All internal gears and differential components are constructed from hardened steel, providing superior wear resistance and longevity compared to softer metals, ensuring smooth operation and consistent performance even during intense racing sessions.
- 31MM Full Differential Case Design — The 31mm size is the precision standard for ARRMA 6S platforms, ensuring flawless compatibility and optimal power distribution to both wheels for superior traction and cornering performance across varied terrain.
- 10/43T Gear Ratio Configuration — The 10-tooth pinion and 43-tooth spur gear combination provides a balanced setup that delivers both responsive acceleration and controlled top speed, making this ideal for mixed-terrain driving whether you're bashing on grass, dirt tracks or rocky ground.
- Full Diff Case System — Unlike limited-slip or locking differentials, a full diff case allows each wheel to rotate independently at different speeds during cornering, which improves turning radius and reduces tyre scrub on technical courses, essential for serious RC bashers.
- Wide Vehicle Compatibility — This upgrade fits ARRMA 6S Mojave, Kraton, Outcast, Typhon and Limitless BLX models, making it a versatile upgrade choice if you run multiple vehicles or plan to switch platforms in future.
- Precision CNC Engineering — Every component is computer-machined to tolerances impossible to achieve with manual production methods, ensuring perfect meshing, smooth operation and minimal backlash that translates to more responsive handling and longer component lifespan.
Technical Performance
The VITAVON Full Diff Case Set represents a significant engineering upgrade for your 1:8 scale brushless RC buggy or truck. Built from CNC-machined aluminium 7075 and hardened steel throughout, this differential system delivers the strength and precision needed to handle the extreme power output of modern 6S brushless systems. The 31mm case diameter is the proven standard for ARRMA 6S platforms including the Mojave, Kraton, Outcast, Typhon and Limitless models, ensuring perfect fitment without modification. The 10/43T gear ratio (10-tooth pinion meshed with a 43-tooth spur gear) provides a carefully balanced setup that prevents the vehicle from over-revving whilst maintaining sufficient acceleration for aggressive driving styles. Unlike cheaper plastic differentials, the full-case design with hardened steel internals distributes torque smoothly and evenly to both wheels, which improves traction control and cornering response. The hardened steel gears resist the wear and stripping that can occur with plastic or soft-metal alternatives, meaning your investment will maintain consistent performance across hundreds of driving sessions. This is the kind of component serious RC enthusiasts upgrade to when they want maximum reliability, predictable handling characteristics and the confidence that their diff system will survive whatever punishment off-road driving delivers.

Frequently Asked Questions
- Is this VITAVON diff case compatible with my ARRMA 6S RC truck? — Yes, this 31mm full diff case set is engineered specifically for ARRMA 6S BLX platforms and fits the Mojave, Kraton, Outcast, Typhon and Limitless models. It will also fit ARRMA Big Rock 6S BLX, Kraton 6S EXB V5, Kraton 6S EXB V6 and Fireteam platforms. Check your vehicle's manual or product code to confirm compatibility before ordering.
- What is the advantage of upgrading to a full diff case instead of keeping the stock differential? — The VITAVON full diff case offers superior engineering through CNC-machined precision and hardened steel internals, compared to cheaper plastic stock components. This upgrade delivers smoother power delivery, better cornering characteristics, improved traction control and significantly longer service life, especially important if you run your brushless RC truck regularly or competitively.
- Why is the 10/43T gear ratio recommended for my RC buggy? — The 10/43T ratio represents a balanced setup between acceleration and top speed. The 10-tooth pinion provides responsive acceleration without over-revving the motor excessively, whilst the 43-tooth spur gear ensures you have usable top-end speed for larger driving areas. This combination is versatile for mixed-terrain driving.
- What materials make this differential case more durable than standard options? — This VITAVON set is constructed from CNC-machined aluminium 7075, an aerospace-grade alloy known for exceptional strength-to-weight ratio, combined with hardened steel gears. These materials resist the cracking, stripping and wear that affect cheaper cast or plastic differentials, providing reliability through years of aggressive driving.
- Can I use this diff case on multiple ARRMA 6S models? — Yes, the 31mm full diff case design is compatible across all ARRMA 6S BLX platforms including Mojave, Kraton, Outcast, Typhon, Limitless and Big Rock models, making this a smart upgrade choice if you own multiple vehicles or plan to switch models in future.
- What tools and skills do I need to install this differential case? — You will need basic RC mechanical knowledge including the ability to remove your vehicle's existing differential, strip components, and reassemble the new case with the provided hardware. We recommend consulting the ARRMA 6S manual and watching installation guides from experienced RC mechanics. If you're uncomfortable with mechanical work, RC Model Shop staff can advise on professional installation options.
- Is this suitable for beginners or only competitive racers? — This component is suited to intermediate and advanced RC enthusiasts with mechanical knowledge. Beginners can certainly use it, but should either educate themselves on differential maintenance and installation or seek assistance from experienced RC mechanics.
