Overview
The ARRMA CVD Driveshaft 50mm (2) Z-ARA311180 is an essential replacement drivetrain component for ARRMA RC enthusiasts across the UK who demand reliability and performance from their vehicles. Whether you're a seasoned RC basher pushing your monster truck to the limits or a weekend racer looking to maintain your GROM model in peak condition, these precision-engineered driveshafts deliver the durability and smooth power transfer your RC car UK experience demands. CVD (Constant Velocity Differential) driveshafts represent a significant upgrade over traditional dogbone designs, offering superior performance across a wider range of driving conditions.
These 50mm CVD Driveshafts are specifically engineered for ARRMA's popular GROM-series vehicles, including the 1/16 GORGON GROM, GRANITE GROM MEGA 380, and QUAKE GROM monster trucks, as well as the 1/14 TYPHON GROM buggies. The pack contains two complete driveshaft assemblies, making it ideal for full drivetrain replacement or keeping spares ready for your next RC adventure. If you're running a brushed or brushless RC monster truck, RC buggy, or any ARRMA GROM platform vehicle, these driveshafts are the perfect fit.
ARRMA has built a reputation for engineering durability into every component, and these CVD driveshafts are no exception. Constructed from tough steel with precision-manufactured components, they're designed to withstand the demanding environments that RC enthusiasts encounter, whether you're bashing through rough terrain, competing in races, or exploring your local RC track.
Key Features
- Tough Steel Construction — Manufactured from high-quality steel, these driveshafts offer exceptional durability and resistance to wear, ensuring they maintain their performance even after extended use in challenging conditions. Steel construction provides superior strength compared to composite alternatives, making these ideal for high-torque applications and aggressive driving styles.
- Precision Engineered CVD Coupling — The CVD (Constant Velocity) coupling system delivers ultra-smooth power transfer to your wheels without the jerky engagement typical of older drivetrain designs. This sophisticated engineering reduces stress on other drivetrain components and provides more consistent acceleration and deceleration characteristics, resulting in better handling and control across all driving conditions.
- Low-Maintenance Design — The sealed CVD coupling requires minimal maintenance compared to traditional open designs, saving you time and money in the long run. You'll spend less time servicing your RC car UK setup and more time enjoying the sport.
- Precision Manufactured Dogbone Pin — Each driveshaft features a precisely engineered dogbone pin that ensures smooth operation in all conditions. This critical component is manufactured to exact tolerances, guaranteeing perfect fit and eliminating play or slop in the drivetrain that could compromise handling or create noise during operation.
- Perfect Replacement Component — As an official ARRMA part, these driveshafts are engineered to exact OEM specifications, ensuring perfect compatibility with your existing drivetrain. No modifications or adjustments required—simply install and enjoy restored performance.
Technical Performance
The ARRMA CVD Driveshaft 50mm represents the pinnacle of drivetrain engineering for GROM-scale RC vehicles. At 50mm in length, these driveshafts are precision-engineered to deliver consistent velocity transfer across the entire range of suspension movement, eliminating the binding and jerky power delivery associated with traditional universal joint designs. The CVD coupling technology employs internal ball bearings that maintain constant velocity regardless of the angle at which the shaft operates, a critical advantage when your RC monster truck or buggy is navigating uneven terrain or aggressive cornering. The steel construction, combined with ARRMA's meticulous manufacturing standards, ensures that these components can handle the high-torque outputs of both brushed and brushless RC drivetrain systems. Whether you're running a GORGON GROM 4x4 RTR brushed monster truck, a GRANITE GROM MEGA 380 with its robust motor, a QUAKE GROM 4x4 brushed setup, or one of the brushless TYPHON GROM models with their enhanced power delivery, these driveshafts provide the performance and reliability you expect from ARRMA components. The precision dogbone pin ensures zero backlash at the connection points, critical for maintaining responsive handling in competitive RC racing or weekend bashing scenarios.

Frequently Asked Questions
- What is a CVD driveshaft and why is it better than traditional dogbone designs? — CVD stands for Constant Velocity Differential, a drivetrain design that maintains equal power delivery to wheels regardless of suspension angle or terrain undulation. Unlike traditional universal joints that can bind and cause jerky power delivery, CVD couplings use internal ball bearings to provide smooth, continuous power transfer. This results in better handling, faster acceleration, reduced drivetrain wear, and superior performance on uneven terrain—making CVD the preferred choice for serious RC enthusiasts across the UK running GROM-series vehicles.
- Will these driveshafts fit my ARRMA GROM RC vehicle? — Yes, these 50mm CVD Driveshafts are specifically designed as OEM replacement components for ARRMA's GROM-series vehicles. They are engineered to ARRMA's exact specifications and will install directly into any compatible GROM model without modification. Compatibility includes the GORGON GROM, GRANITE GROM, QUAKE GROM, and TYPHON GROM platforms in their various brushed and brushless configurations.
- How many driveshafts come in this package? — This package contains two complete 50mm CVD Driveshaft assemblies. Since most ARRMA vehicles require one driveshaft per axle (front and rear), this package provides sufficient components for a full drivetrain replacement. Having a spare driveshaft on hand is also recommended by experienced RC enthusiasts for competitive racing or intensive bashing sessions.
- Do I need any special tools to install these driveshafts? — Installation of these driveshafts requires only basic RC tools typically found in any enthusiast's workshop. You may need a hex wrench or screwdriver to remove the old driveshafts and install the new ones, depending on your specific GROM model. Refer to your vehicle's instruction manual for detailed installation procedures and torque specifications.
- How long will these driveshafts last? — ARRMA's tough steel construction and precision engineering means these driveshafts are built for durability. With proper maintenance and normal usage, they should provide thousands of miles of reliable service. Lifespan depends on driving intensity, terrain conditions, and maintenance practices. Inspect them regularly for damage and replace if bent, cracked, or exhibiting excessive play.
- Can I use these on a brushless ARRMA GROM vehicle? — Yes, absolutely. These CVD Driveshafts are fully compatible with both brushed and brushless ARRMA GROM vehicles, including the TYPHON GROM 223S BLX models. The increased power output of brushless systems actually benefits from the smooth, consistent power delivery that CVD technology provides.
- What makes ARRMA driveshafts different from aftermarket alternatives? — As genuine ARRMA components, these driveshafts are engineered and manufactured to the exact specifications of your vehicle. They undergo rigorous quality control testing and are designed to work seamlessly with every other component in your RC drivetrain. Using official ARRMA parts ensures perfect fit, optimal performance, and compatibility with your vehicle's existing systems.
