Key Features

• Hybrid Alu7075 and HD Steel Construction — The combination of aircraft-grade aluminium 7075 with hardened steel components creates an ideal balance between weight reduction and impact resistance, ensuring your differential housing can withstand the extreme stresses of high-power 6S LiPo RC driving without cracking or deforming.
• 29mm V2 Case Size — This is the correct case dimension for ARRMA Mojave EXB and Kraton EXB models with 29mm differentials, ensuring perfect fitment and compatibility with your existing drivetrain without requiring additional modifications.
• CNC-Precision Machined — Every component is manufactured to tight tolerances using computer numerical control machinery, guaranteeing consistent quality and perfect fitment between the case halves and internal bearing surfaces for smooth, reliable operation.
• Two-Piece Design for Easy Maintenance — Unlike single-piece cases that require complete drivetrain disassembly to access internal components, the two-piece construction allows you to open the differential quickly for cleaning, inspection, and maintenance without removing the case from your RC car.
• Enhanced Durability for 6S Brushless Power — Engineered specifically to handle the tremendous forces generated by modern 6S LiPo brushless RC cars, this case is substantially more robust than standard plastic housings, providing peace of mind during aggressive driving and racing.
• Direct Fitment for Multiple ARRMA Models — Compatible with the ARA7204 Arrma Mojave EXB, ARA8606V5 Arrma Typhon, ARA8708V5 Kraton 6S EXB, and ARA7618T1/ARA7618T2 Arrma Fireteam variants, making it a versatile upgrade for several models in the ARRMA 6S range.
• Available in Silver and Red Colours — Choose your preferred finish to match your RC car's aesthetics whilst benefiting from the same premium performance and durability regardless of colour choice.
• Proven Performance Upgrade — Vitavon components are trusted by RC enthusiasts worldwide, with extensive field testing demonstrating that this differential case upgrade significantly improves reliability during high-speed running and aggressive bashing.

Technical Performance

The VITAVON 29mm V2 Diff Case represents engineering at its finest, combining materials science with precision manufacturing to create a component that dramatically outperforms standard plastic differential housings. The use of aluminium 7075 — the same material specification used in aerospace applications — provides exceptional strength-to-weight ratio, allowing your RC car to maintain responsive handling whilst gaining bulletproof drivetrain reliability. The hardened steel inserts provide additional impact resistance in critical wear zones, ensuring that normal operating stresses and the occasional impact during aggressive RC driving won't cause premature failure. The hybrid construction approach is particularly clever because it allows Vitavon to place the strongest materials exactly where they're needed most, reducing unnecessary weight in non-critical areas. This is the kind of thoughtful engineering that separates premium aftermarket components from basic upgrades. For RC hobbyists running high-powered 6S brushless systems in their ARRMA Mojave EXB, Kraton EXB, or Kraton 6S EXB models, this diff case upgrade delivers the durability required for consistent, reliable performance session after session. The two-piece design innovation is particularly valuable during maintenance, as you can access internal differential gears, bearings, and lubricant without complete drivetrain disassembly, saving valuable time at the track or field. Internal bearing surfaces are CNC-machined to exacting tolerances, eliminating play and ensuring smooth gear rotation even under extreme cornering loads.

Compatibility and Model Verification

This 29mm V2 case is engineered for specific ARRMA models. The manufacturer emphasises checking your part number carefully before purchasing. This case is compatible with: ARA7204 Arrma Mojave EXB, ARA8606V5 Arrma Typhon, ARA8708V5 Arrma Kraton 6S EXB, and ARA7618T1/ARA7618T2 Arrma Fireteam. Please verify your vehicle's model designation before ordering to ensure compatibility. This differential case is NOT compatible with the 31mm diff cases found on some ARRMA 6S BLX variants — you must have a 29mm differential equipped vehicle for this part to fit correctly. If you're unsure about your model's specifications, we recommend contacting our expert RC team at RC Model Shop before purchase.

Frequently Asked Questions

• What is the difference between the 29mm V2 case and the 31mm case? — The 29mm V2 case (this product) fits ARRMA vehicles with 29mm differentials including Mojave EXB and Kraton EXB. The 31mm case is designed for larger-diameter differentials found in ARRMA 6S BLX models. These cases are not interchangeable, so verify your vehicle's differential size before purchasing. Vitavon also manufactures compatible upgrade gears for both case sizes, allowing you to customise your drivetrain performance.
• Will this diff case improve my RC car's performance? — The primary benefit is durability and reliability rather than increased speed. By upgrading to this aluminium and hardened steel case, you eliminate the risk of plastic case cracking or stripping, which is common under 6S power. The improved bearing surfaces and two-piece design also reduce friction slightly, and the rigid construction prevents case flex that can waste power. Real-world improvements include fewer mechanical failures during racing or bashing, faster maintenance access, and the confidence to push your RC car harder without worrying about drivetrain failure.
• Is this case compatible with my ARRMA Kraton 6S? — It depends on your specific Kraton variant. This 29mm V2 case fits the newer Kraton 6S EXB model (ARA8708V5). The original Kraton 6S and Kraton 6S V6 may use different differential sizes. Check your vehicle's part number carefully, and if you're uncertain, contact our RC Model Shop team to verify compatibility before ordering.
• Can I use my existing differential gears in the new case? — Yes, in most instances your factory gears will fit into the new case. However, Vitavon manufactures upgraded spider gear sets specifically designed for the 29mm case (such as the Arrma 6S EXB HD Spider Gear/Diff Gear Set Ar310985), which offer enhanced durability and performance if you want to fully optimise your drivetrain. Using upgraded gears in this premium case maximises the benefits of your investment.
• How much does this upgrade cost and is it worth it? — At £36.00, the VITAVON 29mm V2 Diff Case represents excellent value for a premium aftermarket upgrade. For serious RC enthusiasts running 6S brushless power, this is one of the most cost-effective reliability upgrades available. Factory plastic differential cases frequently fail under aggressive 6S driving, costing you far more in repair downtime and replacement drivetrain components. Investing in this proven, durable case at the outset saves money long-term.
• Is installation difficult? — If you're comfortable servicing your RC car's drivetrain, installation is straightforward as the case simply replaces your existing differential housing. The two-piece design makes removal of the old case and installation of the new one relatively simple. If you've never worked on RC drivetrain components before, we recommend our RC Model Shop team walk you through the process or assist with installation in-store.
• What colours are available? — The VITAVON 29mm V2 Diff Case is available in Silver and Red finishes. Both offer identical performance — the colour choice is purely aesthetic to match your RC car's paint scheme or personal preference.
• Will this case fit my stock ARRMA vehicle or do I need other upgrades? — This case is designed as a direct replacement for the factory plastic differential housing and requires no additional modifications. However, to fully benefit from the premium case, many RC enthusiasts also upgrade the internal differential gears to hardened steel versions for maximum durability. The upgraded spider gears are optional but recommended if you regularly push your 6S RC car to its limits.
