RC Model Shop stocks genuine ARRMA spares and upgrades, ensuring you receive authentic components that match the quality and performance standards of your RC model. This is the kind of upgrade that serious RC enthusiasts in the UK turn to when they want to maximise the reliability and performance of their 4x4 brushless RC cars.
Key Features
- CVD Constant Velocity Design — The CVD (constant velocity) differential construction ensures smooth, consistent power delivery to the wheels throughout the full range of motion, which is essential for maintaining traction during aggressive cornering, acceleration and deceleration in RC 4WD vehicles.
- Designed for ARRMA 4x4 BLX Models — These outdrives are engineered specifically to work with ARRMA's 4x4 BLX brushless platform, ensuring perfect fitment and compatibility with your existing drivetrain components.
- Two-Pack Quantity — This pack contains two outdrives, providing you with a complete set of replacements or upgrades for both sides of your RC vehicle's drive system.
- Proven Durability — ARRMA components are recognised throughout the RC hobby for their robust engineering and reliable performance under demanding conditions, making these outdrives suitable for both casual bashing and competitive racing.
- Genuine OEM Component — As an official ARRMA part, you can be confident that these outdrives meet the manufacturer's quality standards and will integrate seamlessly with your existing setup.
Technical Performance
The ARRMA CVD Differential Outdrive represents the engineering philosophy that ARRMA brings to their 4x4 BLX brushless RC range. The constant velocity design is fundamental to smooth power delivery in modern RC vehicles, particularly when running high-torque brushless motors that can generate intense forces through the drivetrain. The CVD joint allows for consistent angular velocity transmission even when the joint is articulated at extreme angles, which is exactly what happens in the suspension geometry of a 4WD RC car or truck during aggressive driving. This design philosophy extends to professional-level RC competition, where reliability and consistent performance are non-negotiable. The outdrives are engineered from materials selected to withstand the repeated shock loads and torque spikes that characterise modern brushless RC driving, whether you're running a 3S LiPo setup for casual bashing or pushing the limits with higher-voltage battery packs in competitive settings.

Frequently Asked Questions
- Which ARRMA models are compatible with these CVD outdrives? — These outdrives are specifically designed for ARRMA 4x4 BLX models. They will not fit other ARRMA platforms or other manufacturers' RC vehicles, so ensure you verify your model compatibility before ordering.
- Are these genuine ARRMA parts? — Yes, these are official ARRMA components supplied as OEM spares. When you purchase from RC Model Shop, you receive authentic parts that meet ARRMA's quality standards and performance specifications.
- Do I need special tools to install these outdrives? — Most RC enthusiasts possess the basic tools needed for outdrive replacement, though specific installation procedures will vary depending on your particular ARRMA 4x4 BLX model. Refer to your vehicle's instruction manual or online guides for detailed installation steps.
- What is the difference between CVD outdrives and standard driveshafts? — CVD (constant velocity) outdrives use a joint design that maintains consistent angular velocity even when bent at extreme angles, delivering smoother power transmission and better traction compared to older standard designs. This is particularly beneficial in 4WD vehicles where suspension articulation is significant.
- How often should I replace my outdrives? — Outdrive lifespan depends on driving conditions and maintenance. Regular inspection is recommended, and replacement should be considered if you notice clicking sounds, excessive play, or vibration during acceleration. Many bashers carry spare outdrives for competition or extended bashing sessions.
- Can I upgrade to these CVD outdrives if my model came with standard outdrives? — Verify your model's compatibility first by checking your vehicle's manual or contacting RC Model Shop directly. Upgrading to CVD outdrives can improve performance and durability, but compatibility must be confirmed.
