Manufactured by ARRMA with precision engineering standards, this replacement driveshaft ensures your GROM continues to deliver the explosive acceleration and reliable performance that the model is known for. Whether you're heading out for a weekend bash session or preparing for competitive racing with your RC buggy or desert truck, having genuine ARRMA spare parts in your toolkit demonstrates a commitment to maintaining your equipment to the highest standards.
Key Features
- Steel Construction — The driveshaft is manufactured from steel material, which provides extreme toughness and durability under the demanding conditions of 4x4 off-road racing and bashing. This material choice ensures the component can withstand the powerful torque delivery of your brushed motor without flexing or breaking, even during hard acceleration and aggressive driving on rough terrain.
- Hex Shape Design — The driveshaft features a hexagonal cross-section that connects to the hex-shaped sockets on your transmission and axles, providing a positive mechanical bond for reliable power transfer. This design prevents slipping and ensures all the power from your motor is efficiently delivered to propel your RC truck forward without energy loss.
- 181mm Length — Precisely measured at 181mm, this driveshaft is specifically dimensioned to fit the 204mm chassis platform found on ARRMA GROM models. The correct length ensures optimal geometry for suspension travel and prevents binding during full articulation of your 4x4 drivetrain.
- Authentic ARRMA Part — This is a genuine manufacturer spare part, not an aftermarket alternative. ARRMA's quality control and engineering specifications ensure perfect compatibility and reliability. When you purchase genuine spares, you're investing in your vehicle's longevity and performance consistency.
- Essential Replacement Component — The centre driveshaft is an ideal replacement for worn factory-supplied items, making this a cost-effective way to refresh your GROM's drivetrain without purchasing a complete new kit. Regular inspection and replacement of driveshafts is part of responsible RC vehicle maintenance.
Technical Performance
The ARRMA Center Driveshaft Steel 181mm is engineered with meticulous attention to detail to match the performance demands of the 1/16 scale MOJAVE GROM 4x4 platform. The steel construction provides exceptional rigidity and resistance to the torsional loads generated by ARRMA's MEGA 380 brushed motor, which delivers impressive torque output for a small-scale RC vehicle. The hexagonal connection points ensure zero play in the drivetrain, which is critical for maintaining responsive handling characteristics during cornering and maintaining linear acceleration delivery. For owners of the GROM running in competitive RTA race kit configuration or enthusiast RTR versions in red or blue, this driveshaft performs identically to the original component, making it the preferred choice for replacements over generic alternatives. The 181mm length has been precisely calculated to work with the 204mm chassis geometry, ensuring proper suspension travel clearance and preventing contact with suspension components during full articulation on rough terrain. Whether you're driving in wet conditions on grass fields, sandy desert-style tracks, or rocky terrain at your local RC car UK club, this steel driveshaft will maintain its integrity and torque transfer characteristics across a wide range of environmental conditions and driving intensities.

Frequently Asked Questions
- What ARRMA models is this driveshaft compatible with? — This 181mm centre driveshaft is compatible with the ARRMA MOJAVE GROM MEGA 380 Brushed 4x4 Small Scale Desert Truck RTR in both red (C-ARA2104T1) and blue (C-ARA2104T2) variants, as well as the 1/16 ARRMA MOJAVE GROM 4x4 RTA Race Kit (C-ARA2104KT1) that includes battery and charger. If you own any of these GROM models, this is the correct replacement part.
- Is this suitable for beginners? — Yes, this spare part is suitable for beginners because it's a straightforward replacement component. While it's not a complete RC car, beginners who have owned a GROM for some time and need to replace a worn driveshaft will find this part relatively easy to install with basic RC maintenance tools and a small amount of mechanical knowledge.
- How do I know if my driveshaft needs replacing? — Over time, driveshafts can wear, bend, or develop play in their hex connections. Common signs include clunking sounds when accelerating, loss of power transfer efficiency, or visible bending. If you suspect drivetrain issues, inspecting the centre driveshaft is a good first troubleshooting step.
- Why should I buy genuine ARRMA parts instead of aftermarket alternatives? — Genuine ARRMA parts like this driveshaft are engineered and tested to work perfectly with your vehicle's specific platform. They ensure compatibility, maintain the vehicle's performance characteristics, and offer peace of mind knowing you're using manufacturer-approved components. Aftermarket parts may fit but could introduce vibration, play, or reliability issues.
- Can this driveshaft be upgraded or modified? — This is a replacement spare part designed to match original specifications. For those interested in upgrades, ARRMA offers alternative drivetrain components through their tuning range, but for reliable replacement with identical performance, this genuine part is the ideal choice.
- How often do driveshafts need replacing? — The lifespan depends on your driving style and conditions. Weekend bashers might get many months or years of use, while competitive racers might inspect and replace driveshafts more regularly. Regular maintenance checks help identify wear early and prevent unexpected breakdowns during RC sessions.
