Key Features
- Stronger Metal Wheel Axles and Hex Drives — The metal construction provides significantly greater durability than standard plastic components, resisting the stresses of high-torque acceleration and rough terrain. This means fewer replacements, less downtime, and more time actually driving your RC car.
- One-Piece CVD Assembly — Rather than separate components that can wear and loosen over time, these drive shafts combine the shaft, axle, hex and threaded insert into a single cohesive unit. This integrated design eliminates play and misalignment, resulting in smoother power delivery and better handling characteristics.
- Replacement for Standard Components — These CVD drive shafts replace the original shaft, axle, hex and threaded insert entirely, making installation straightforward for anyone familiar with basic RC maintenance. Simply remove the old parts and install the new one-piece assembly.
- Included Alloy Wheel Hex — The supplied alloy wheel hex provides additional support at the critical wheel interface where drive shafts typically experience the greatest stress. This feature ensures that power transfer to the wheels remains consistent and prevents the loose, sloppy feeling that develops in stock Groms over time.
- Matched Front Pair — This pack includes both front CVD drive shafts as a complete matched pair, ensuring symmetrical performance on both sides of your vehicle for balanced handling and predictable driving characteristics.
- Designed for Brushed Grom Models — These shafts are specifically engineered for brushed Grom variants, delivering the right balance of strength for these motors. Note that these are not compatible with the brushless version of the Grom.
Technical Performance
The RC Overhaul Metal CVD Drive Shafts represent a thoughtful engineering solution for a common weakness in budget-friendly RC vehicles. The original plastic drive shafts in the ARRMA Grom are prone to stripping, cracking and wearing, particularly in the hex drives where power transfers to the wheels. By upgrading to metal construction, you gain immediate benefits including reduced flex under load, improved power transmission efficiency, and dramatically extended component lifespan. The one-piece design eliminates the weak points created by threaded connections and separate hex inserts, creating a more robust assembly that handles the torque output of brushed 380-class motors effectively. The included alloy wheel hex is particularly important, as this is where most wear occurs in standard setups — by addressing this specific stress point with quality materials, RC Overhaul ensures that the entire drivetrain works in harmony. Whether you're running on carpet, dirt or concrete, these shafts maintain consistent performance and respond predictably to throttle inputs. For UK RC car owners looking to extend the life of their 1/18 Grom or Typhon and reduce frustrating breakage-related downtime, this upgrade delivers tangible improvements in reliability and performance.

Frequently Asked Questions
- Is this upgrade compatible with my ARRMA Grom? — Yes, these RC Overhaul Metal CVD Drive Shafts are fully compatible with multiple Grom variants including the 1/18 GRANITE GROM MEGA 380 Brushed 4x4 Monster Truck and the 1/14 TYPHON GROM MEGA 380 Brushed 4x4 Buggy. The product is specifically designed as a direct replacement for the standard drive shafts on these models. However, these shafts are designed for brushed Grom models only and are not compatible with the brushless version.
- What models is this compatible with? — The G-RCO-AR008 is compatible with the following models: ARRMA 1/18 GRANITE GROM MEGA 380 Brushed 4x4 Monster Truck RTR (available in Blue/Red, Green, and Red variants) and the ARRMA 1/14 TYPHON GROM MEGA 380 Brushed 4x4 Buggy RTR (available in Blue/Silver and Red/White). If you own a different scale Grom or a brushless variant, please verify compatibility before purchasing.
- How difficult is installation? — Installation is straightforward for anyone with basic RC maintenance experience. The shafts simply replace the original components by removing the old shaft, axle, hex and threaded insert and installing the new one-piece assembly. Most users can complete the upgrade in under 10 minutes per side. If you're new to RC maintenance, our team at RC Model Shop can provide guidance or you may prefer to have a technician perform the installation.
- Why do I need this upgrade if my Grom still works? — Whilst standard plastic drive shafts work initially, they gradually wear and develop play in the hex connections, resulting in a sloppy, unresponsive feel. More importantly, they are prone to sudden failure during hard acceleration or rough terrain driving. By upgrading proactively to metal CVD shafts, you prevent frustrating breakdowns, maintain consistent driving performance, and ultimately save money on repeated replacements and repairs.
- What does CVD stand for? — CVD stands for Constant Velocity Drive, a design that allows the drive shaft to transmit power smoothly and consistently across different angles. This is particularly important in RC vehicles where the suspension moves through a range of motion. The CVD design ensures that power delivery remains consistent regardless of suspension position.
- Can I use these on the brushless Grom model? — No, these shafts are specifically designed for brushed Grom models and are not compatible with the brushless version. The brushless variant has different drivetrain specifications. Please verify your Grom model type before ordering.
