- Wide Model Compatibility — This part is engineered to fit a comprehensive range of ARRMA's most popular 4WD and 4x4 brushless RC models, from 1/10 scale monster trucks and short course trucks to 1/8 scale buggies and desert trucks, making it a versatile upgrade suitable for multiple vehicles in your collection.

Technical Performance
The Metal Center Diff Outdrive Set is engineered to enhance the drivetrain performance and longevity of ARRMA's brushless 4WD and 4x4 vehicles. The metal construction provides substantially greater resistance to bending, cracking and stripping compared to plastic outdrive components, which makes these parts ideal for drivers who regularly push their RC cars to high speeds or who run them in aggressive conditions. The outdrives work as part of the centre differential system, which is critical to how power is distributed between the front and rear axles during cornering and acceleration. By upgrading to metal outdrives, you're directly improving the efficiency of power transfer and reducing drivetrain losses that occur when plastic components flex or degrade under load. This results in more responsive handling, better traction distribution, and ultimately a more enjoyable and faster RC vehicle. The set is compatible with ARRMA's DSC-equipped models and their latest V2 and V4 generation vehicles, spanning scales from 1/10 to 1/8, which means whether you're running a 4WD stadium truck, a 4x4 monster truck, or a 4x4 buggy, these outdrives represent a genuine performance and reliability enhancement. Installation is straightforward for anyone with basic RC maintenance skills, and having a spare set on hand ensures minimal downtime when drivetrain maintenance is required.

Frequently Asked Questions
- Which ARRMA RC models are compatible with the Metal Center Diff Outdrive Set Z-ARA311168? — This part is compatible with a wide range of ARRMA's most popular brushless 4WD and 4x4 models including the Big Rock 223S DSC (all colour variants), Granite 223S DSC (all colour variants), Kraton 4x4 4S V2 BLX, Outcast 4x4 4S V2 BLX, Senton 223S BLX with DSC, Typhon 223S BLX with DSC, Vorteks 223S BLX with DSC, and the Mojave 4x4 4S BLX desert truck. If you own any of these models, this is a direct replacement and upgrade component.
- Should I upgrade to metal outdrives or stick with plastic? — Metal outdrives offer superior durability and performance compared to the plastic alternatives, particularly if you regularly bash your RC car hard or run it at high speeds. The metal construction resists bending and stripping much more effectively, which means longer component life and better power transmission efficiency. For serious RC enthusiasts running brushless 4x4 vehicles, metal outdrives are a worthwhile upgrade that will save you money on replacement parts over time.
- Is this a difficult upgrade to install on my ARRMA RC truck or buggy? — Installation of the centre diff outdrives requires basic RC maintenance skills and some mechanical knowledge, as you'll need to access the centre differential on your model. While not particularly complex, it's not a task for complete beginners. If you're not confident working on your RC vehicle's drivetrain, your local RC hobby shop may be able to help with installation.
- What is the difference between metal and plastic outdrives? — Metal outdrives are significantly more durable and resistant to damage compared to plastic versions. Plastic components can bend, crack or strip under heavy loads, particularly during aggressive driving or when running a brushless motor with high power output. Metal outdrives maintain their shape and structural integrity much better, resulting in improved long-term reliability and consistent performance.
