Overview
Upgrade your 1/18 scale Arrma Grom to professional-grade performance with the RC Overhaul Metal CVD Drive Shafts Rear. Whether you're a dedicated RC enthusiast in the UK looking to improve your brushed Grom's durability or a weekend basher wanting to reduce maintenance downtime, these metal CVD shafts represent a significant step up from standard plastic components. The Grom has become one of the most popular entry-level RC cars in the UK, and upgrading the drivetrain is one of the smartest investments you can make to extend the life of your vehicle and improve reliability on the track or off-road.
These rear CVD drive shafts are engineered to replace the weak points in your Grom's transmission system. Instead of using separate components that can wear, bend or break under stress, RC Overhaul has designed a complete one-piece metal solution that combines the shaft, axle, hex and threaded insert into a single robust unit. This integrated design eliminates the failure points that plagued earlier Grom models and delivers the strength needed for consistent, reliable performance whether you're bashing in your garden or competing at your local RC club.
If you own an Arrma 1/18 Granite Grom or Typhon Grom in any colour variant (Blue/Red, Green, or Red/White), these metal CVD shafts are the upgrade you've been waiting for. They're specifically designed for the brushed versions of these vehicles, delivering immediate improvements in drivetrain strength and longevity. Ready to take your RC car UK experience to the next level? Read on to discover why these shafts are an essential upgrade for serious Grom owners.
Key Features
- Complete One-Piece Metal Construction — Rather than relying on separate shaft and axle components that can disconnect or fail, these CVD drive shafts integrate the shaft, axle, hex and threaded insert into a single machined metal unit, eliminating weak points and ensuring consistent power delivery to your wheels.
- Stronger Metal Wheel Axles and Hex Drives — The upgraded metal construction provides significantly greater strength than the standard plastic hexes, reducing the risk of stripping, cracking or bending during hard driving, jumps or aggressive cornering.
- Included Alloy Wheel Hex — Each shaft features an alloy wheel hex that provides additional support at the wheel interface, distributing load more evenly and preventing the looseness that develops in standard plastic hubs after extended use.
- Simplified Assembly — The one-piece design means fewer components to align, install and maintain, making installation straightforward and reducing the chance of misalignment that can cause vibration or premature wear.
- Direct Replacement for Standard Shafts — These CVD shafts are designed as a direct replacement for the factory rear shafts, axles and hexes on your Grom, making installation quick and requiring no modifications to your vehicle.
- Complete Rear Axle Solution — You receive a matched pair of rear CVD drive shafts, giving you everything needed to upgrade both rear corners of your vehicle in one purchase.
Technical Performance
The RC Overhaul Metal CVD Drive Shafts represent a substantial engineering improvement over standard Grom components. Built from precision-machined metal alloys rather than injection-moulded plastic, these shafts deliver superior strength-to-weight characteristics that make them ideal for the 1/18 scale Grom platform. The constant-velocity (CVD) design ensures smooth power delivery at various suspension angles, which is particularly important on a compact vehicle like the Grom where suspension articulation can be pronounced during aggressive driving. The one-piece construction eliminates the traditional failure modes seen in multi-component shaft assemblies — there's no weak joint between shaft and axle, no plastic hex that can strip under torque, and no threaded insert that can work loose. The included alloy wheel hex is precision-engineered to match the tolerance stack of the rest of the assembly, meaning your wheels will stay securely mounted and won't develop the wobble associated with worn plastic hubs. For brushed motor Grom models (the MEGA 380 variants), these shafts provide a dramatic improvement in drivetrain reliability and longevity, allowing you to spend more time driving and less time repairing.

Frequently Asked Questions
- Which Grom models are compatible with these metal CVD drive shafts? — These rear shafts are designed specifically for brushed Grom models, including the Arrma 1/18 Granite Grom MEGA 380 (available in Blue/Red, Green, and Red/White colour options) and the Arrma 1/14 Typhon Grom MEGA 380 (available in Blue/Silver and Red/White). They are not compatible with brushless versions of these vehicles. Always verify your model number before purchasing.
- Why are metal CVD shafts better than the standard plastic shafts that come with my Grom? — Plastic shafts and hexes are prone to stripping, cracking and bending, especially during hard driving, jumps or after extended use. Metal CVD shafts distribute forces more evenly, resist stripping even under high torque, and maintain their precision fit far longer. The one-piece construction also eliminates the weak joints that develop in multi-component assemblies, giving you more reliable drivetrain performance and fewer breakages.
- Is installation of these CVD shafts difficult? — No. These shafts are designed as a direct replacement for your Grom's factory rear shafts and require no modifications to your vehicle. If you're comfortable performing basic RC car maintenance, you can install these yourself. They simply remove and replace the existing rear shaft assembly. Many UK RC enthusiasts perform this upgrade during routine maintenance or when replacing worn components.
- Will these shafts work with my Grom if I've already upgraded other parts? — Yes. These CVD shafts are a standalone drivetrain upgrade that works with the standard Grom suspension, motor and transmission components. They can be installed without upgrading or modifying any other parts of your vehicle.
- How long will these metal CVD shafts last? — Metal construction provides dramatically longer service life compared to plastic components. With proper maintenance and regular cleaning to prevent dirt accumulation in the CVD joints, these shafts should last for hundreds of runs. Exactly how long depends on your driving style, maintenance regime and track conditions, but most users report significantly reduced wear compared to factory components.
- Are these shafts suitable for both casual and competitive use? — Absolutely. Whether you're a weekend basher exploring local green spaces or a competitive racer at your RC club, these metal CVD shafts provide the reliability and durability needed for consistent performance. Many competitive Grom drivers use metal CVD upgrades as part of their standard setup.
