Technical Performance
The ARRMA Driveshaft Set, Short (2pcs) represents precision-engineered drivetrain technology designed for the demanding requirements of small-scale RC desert truck racing and recreational bashing. Driveshafts are critical power transmission components that transfer rotational force from your GROM's motor through the transmission system to the wheels, making them essential to your model's acceleration, top speed capability, and overall handling characteristics. The short configuration is specifically optimised for the GROM's compact chassis geometry and suspension layout, ensuring proper driveline angles and eliminating binding or premature wear that could result from incorrect shaft lengths. ARRMA's engineering expertise in small-scale RC vehicles means these driveshafts are manufactured from materials selected for their durability under the high-torque conditions generated by the MEGA 380 brushed motor system and the rugged demands of 4WD desert driving. Whether navigating rough terrain, executing high-speed manoeuvres, or competing in organised racing events, quality driveshaft components are fundamental to maintaining responsive steering input translation, consistent power delivery to all four wheels, and the reliability that RC enthusiasts across the UK demand from their models. Regular inspection and timely replacement of worn driveshafts helps prevent secondary damage to gearboxes and motor assemblies, ultimately protecting your investment in your GROM.

Frequently Asked Questions
- What GROM models are these driveshafts compatible with? — These short driveshafts are designed specifically for the ARRMA MOJAVE GROM MEGA 380 Brushed 4x4 small-scale desert truck, compatible with both the red (C-ARA2104T1) and blue (C-ARA2104T2) colour variants. Always verify your model's specific part number before ordering to ensure correct fitment.
- Why would I need replacement driveshafts for my RC car? — Driveshafts are precision drivetrain components that endure constant rotational stress and impact forces during normal operation. Extended use, particularly in competitive racing or aggressive bashing, can result in wear, bending, or breakage of these critical components. Keeping spare driveshafts on hand ensures your GROM remains race-ready or ready for weekend fun without extended downtime waiting for parts to arrive.
- How do I know if my driveshafts need replacing? — Common signs of driveshaft wear or damage include vibration or clunking noises from the drivetrain during operation, reduced power transmission to the wheels, visible bending or cracks in the shafts, or excessive play when manually rotating the wheels with the motor disengaged. If you experience any of these symptoms, replacement driveshafts should be fitted immediately to prevent damage to other drivetrain components like the gearbox or motor.
- Are these genuine ARRMA parts? — Yes, these driveshafts are authentic ARRMA components manufactured to the exact specifications required by the GROM platform. RC Model Shop is an authorised ARRMA retailer in the UK, guaranteeing that all parts we supply are genuine, not counterfeit or inferior aftermarket alternatives. This assurance of authenticity is crucial for maintaining your model's performance and reliability.
- What tools do I need to install these driveshafts? — Installation of driveshaft components typically requires basic RC maintenance tools such as hex keys and potentially small pliers or tweezers for removing retaining clips or fasteners. Consult your GROM user manual or instruction guide for specific installation procedures, torque specifications, and any lubricants recommended by ARRMA for optimal drivetrain performance.
- Can I use these driveshafts on other ARRMA models? — These driveshafts are engineered specifically for the GROM platform and are not compatible with other ARRMA models, as different chassis designs require different driveshaft lengths and configurations. Always verify your model's compatibility before purchasing replacement parts to avoid fitment issues and ensure safe operation of your RC vehicle.
