Key Features
- Composite Construction — The differential case is manufactured from composite material, providing an excellent balance between weight savings and structural durability, ensuring your centre diff can withstand the stresses of aggressive driving without unnecessary bulk.
- Complete Power Module Set — This is a full power module package rather than individual components, meaning all the internal gearing and mechanical elements are pre-matched and engineered to work together seamlessly for optimal differential action.
- Factory-Engineered Design — As an official ARRMA component, this centre diff module has been developed and tested by the manufacturer to ensure compatibility and performance across their vehicle lineup, giving you confidence in quality and reliability.
- Drivetrain Optimisation — The centre differential is critical to how your RC car distributes power between front and rear axles, and upgrading to this module can improve traction, handling balance, and overall drivetrain responsiveness during cornering and acceleration.
- Direct OEM Compatibility — As an official ARRMA part, this module integrates perfectly with ARRMA vehicle platforms, ensuring hassle-free installation without modification or adaptation.
Technical Performance
The ARRMA Composite Center Diff Power Module represents the manufacturer's commitment to precision engineering in drivetrain components. The composite material construction provides the ideal combination of rigidity and impact resistance, whilst internal mechanical components are engineered to precise tolerances for smooth operation and minimal parasitic losses. This centre diff module manages the critical function of power distribution in your RC car's transmission, allowing the front and rear axles to rotate at different speeds during cornering whilst maintaining traction during acceleration. The composite casing integrates with ARRMA's broader drivetrain architecture, and the internal design reflects lessons learned from extensive testing and real-world racing feedback. The module's performance characteristics make it particularly valuable for drivers running their RC cars in demanding conditions, whether that's high-speed desert driving, technical off-road courses, or competitive racing circuits. The engineering quality ensures consistent performance across multiple drive sessions without degradation, whilst the material choice balances durability with the weight considerations important in competitive RC racing.

Frequently Asked Questions
- What is a centre differential and why would I want to upgrade to this module? — The centre differential is the component that manages power distribution between your RC car's front and rear axles, allowing them to rotate at different speeds when cornering. Upgrading to this composite power module can improve handling characteristics, traction response, and drivetrain efficiency, making it a worthwhile upgrade for owners looking to optimise their vehicle's performance or replace worn factory components.
- Is this suitable for beginners or mainly for experienced RC enthusiasts? — This is a replacement component rather than a complete ready to run RC set, so it's primarily suitable for RC car owners who already have an ARRMA vehicle and possess basic mechanical skills for drivetrain maintenance and upgrade work. Beginners should ensure they have the necessary tools and technical knowledge before attempting installation.
- Which ARRMA vehicles is this centre diff module compatible with? — Whilst the source material indicates this is an ARRMA individual part, we recommend checking the specific model compatibility section or contacting our RC Model Shop team to confirm which ARRMA platforms use the Z-ARA311236 module, as ARRMA manufactures centre diffs for various scales and vehicle types.
- What materials and construction methods does this centre diff use? — The power module features composite material construction combined with internal mechanical components engineered by ARRMA. The composite casing provides durability and weight efficiency, whilst the internal drivetrain elements are designed for consistent power delivery and minimal mechanical resistance during normal operation.
- How does upgrading to this composite centre diff module improve my RC car's performance? — A quality centre differential upgrade can enhance your vehicle's cornering ability by allowing smoother speed differential between front and rear axles, improve traction response during acceleration, and provide more responsive handling feedback. These improvements accumulate to give you better overall vehicle control and driving satisfaction.
