Key Features

• Premium Alu7075 Aluminium Construction — The case is machined from aerospace-grade Alu7075 aluminium, which provides exceptional strength-to-weight ratio and superior durability compared to standard plastic or cheaper aluminium alternatives. This material choice means your differential case will resist damage from high-speed impacts and extreme conditions whilst remaining lightweight enough not to impact vehicle performance or handling characteristics.
• Hardened Steel 45# Internal Components — The internal gears and mechanisms utilise hardened steel grade 45#, which dramatically extends the lifespan of differential components under heavy acceleration, cornering loads, and sustained high-speed running. Steel components resist stripping and deformation far better than plastic alternatives, meaning your investment will last through countless bashing sessions and competitive events.
• 29MM Full Differential Case Assembly — The 29mm case diameter is optimised for ARRMA 6S-scale vehicles, providing the perfect balance of strength and weight distribution. A full differential case assembly means all internal components are included and precisely matched, ensuring smooth operation and predictable handling characteristics across all driving conditions.
• 44-Tooth Spur Gear Included — The 44T spur gear is included in this set, eliminating the need to source this critical component separately. The tooth count directly affects your vehicle's speed and acceleration characteristics, and this specification is engineered to work perfectly with the ARRMA 6S drivetrain architecture.
• Centre Bulkhead Compatibility — This differential case is designed to fit the centre bulkhead position on compatible ARRMA vehicles, making it a straightforward upgrade for existing owners. The precise manufacturing ensures alignment with your vehicle's chassis and other drivetrain components without modification.
• Broad Vehicle Compatibility — Compatible with the ARRMA Mojave 6S, Kraton 6S, Outcast 6S, Typhon 6S, Notorious 6S, Limitless 6S, and Fireteam models, as well as the newer EXB versions (including the ARA8708V5 Kraton 6S EXB). This wide compatibility means you can confidently order knowing it will fit your specific model variant.
• Silver and Black Colour Finish — The attractive two-tone silver and black finish not only looks professional but also helps with identification and maintenance tracking. The colour combination is designed to complement most ARRMA vehicle colour schemes whilst maintaining a premium appearance.
• CNC-Precision Manufacturing — Every component in this set has been CNC-machined to tight tolerances, ensuring perfect fit, minimal play, and consistent performance. This precision manufacturing is what separates quality aftermarket components from budget alternatives, and directly impacts how smoothly your vehicle handles and accelerates.

Technical Performance

The VITAVON Center Full Diff Case Set represents a significant engineering achievement in RC drivetrain components. The use of Alu7075 aluminium combined with hardened steel 45# creates a material combination that offers superior performance characteristics compared to standard OEM plastic differential cases. The 29mm case diameter is specifically engineered for ARRMA 6S-scale vehicles, which operate with 4WD drivetrain systems, short-course truck architecture, and buggy-style suspension geometry. The 44-tooth spur gear provides the correct gear ratio for these vehicles, optimising the power delivery from your brushless motor and ESC to the wheels whilst maintaining appropriate acceleration and top-speed characteristics. This centre differential assembly is designed to handle the extreme loads generated by 6S LiPo batteries, brushless motors rated in the 3000-5000KV range, and ESCs capable of handling 160+ amp discharge currents. The full differential case set means all internal components—including spider gears, thrust washers, and bearing surfaces—are included and pre-assembled to exact specifications. This eliminates the need for field assembly and potential misalignment issues. The CNC-precision manufacturing ensures that component tolerances are held to within hundredths of a millimetre, which directly translates to smooth differential action, predictable handling, and minimal drivetrain noise. Whether you're running on tarmac surfaces for drift cars, rocky terrain for crawlers, or high-speed off-road circuits for buggies and short-course trucks, this differential case set will distribute power smoothly across the wheels whilst allowing the vehicle to turn through corners without binding or over-locking.

Frequently Asked Questions

• Is the VITAVON Center Full Diff Case Set compatible with my ARRMA Kraton 6S? — Yes, this set is explicitly designed for ARRMA Kraton 6S models, including both standard and EXB versions. The manufacturer confirms compatibility with ARA8608V5T1, ARA8608V5T2, and the newer ARA8708V5 Kraton 6S EXB. If you own any of these specific model variants, this differential case will fit your centre bulkhead without modification.
• What makes Alu7075 aluminium better than standard plastic differential cases? — Alu7075 is an aerospace-grade aluminium alloy that provides dramatically superior strength and impact resistance compared to injection-moulded plastic. Whilst plastic cases can crack or shatter under heavy impacts, Alu7075 cases flex slightly and absorb energy without permanent damage. Additionally, aluminium dissipates heat better than plastic, which becomes important during extended high-speed running sessions. The material choice directly impacts the longevity and reliability of your vehicle's drivetrain.
• Will this upgrade improve my vehicle's performance? — This differential case upgrade improves performance in several ways. Firstly, the precision CNC manufacturing ensures minimal internal play and smooth power delivery compared to standard cases. Secondly, the hardened steel 45# internal components resist wear and maintain consistent differential action over time, whereas plastic components can degrade and cause sloppy handling. Thirdly, the full case assembly is pre-set to optimal specifications, eliminating guesswork in differential tuning. For racing applications or high-performance driving, these improvements translate to better acceleration feel, more predictable cornering, and reduced drivetrain noise.
• What is the difference between this VITAVON set and the standard ARRMA factory differential? — The factory ARRMA differential case is typically injection-moulded plastic and designed for cost-effectiveness rather than ultimate performance. This VITAVON upgrade features aerospace-grade Alu7075 aluminium that won't crack or break under extreme loads, hardened steel internal components that resist stripping and wear, and CNC precision manufacturing that ensures tight tolerances. The result is a component that lasts significantly longer, performs more smoothly, and maintains consistency throughout its lifespan. For serious RC enthusiasts in the UK who run their vehicles frequently, this upgrade is considered a worthwhile investment.
