Overview
The Fastrax Arrma Grom/Granite Metal Rear CVD Driveshafts represent a premium upgrade option for owners of the Arrma 1/18 Granite Grom monster truck range. If you're serious about maintaining peak performance from your RC car UK, these metal driveshafts are an essential consideration. The Grom and Granite platforms have become incredibly popular within the UK RC community, and upgrading to metal rear CVD driveshafts is one of the most effective ways to enhance durability and reliability during intense bashing sessions.
These driveshafts are engineered to replace the standard components found on your Arrma Granite Grom, providing superior strength and longevity compared to plastic alternatives. Whether you're a weekend basher tackling rough terrain or someone pushing your ready to run RC truck to its limits, metal driveshafts will significantly extend the lifespan of your drivetrain. The constant velocity (CVD) design ensures smooth power delivery to the rear wheels, maintaining consistent performance even when your truck is cornering or navigating uneven ground.
For RC enthusiasts in the UK looking to upgrade their Grom or Granite without breaking the bank, the Fastrax metal rear CVD driveshafts offer outstanding value. This is a genuine performance upgrade that transforms how your truck handles, reduces maintenance downtime, and keeps you racing or bashing rather than repairing. Fastrax is a recognised name in the RC industry, and their components are trusted by hobbyists and competitors alike.
Key Features
- Metal Construction — These driveshafts are manufactured from metal rather than plastic, providing significantly increased strength and durability. Metal components resist impact damage and wear far better than plastic equivalents, meaning your rear drivetrain will withstand the punishment of aggressive driving without breaking or wearing out prematurely.
- CVD Design — The constant velocity joint design ensures smooth power delivery throughout the entire range of motion. This translates to more consistent performance when accelerating, cornering, and navigating obstacles, while also reducing vibration and noise compared to standard shafts.
- Direct OEM Replacement — These shafts are designed as a drop-in replacement for the standard rear driveshafts on your Arrma Granite Grom, meaning installation is straightforward with no additional modifications or adjustments required. Simply remove the original shafts and install these upgrades.
- Supplied as a Pair — You receive both rear driveshafts in this package, so you have everything needed to upgrade the entire rear drivetrain in one transaction. No need to source components separately or make multiple purchases.
- Enhanced Longevity — By upgrading to metal components, you dramatically increase the service life of your rear drivetrain. This means fewer replacements over time, less downtime waiting for parts, and a more reliable truck ready for action whenever you are.
- Improved Off-Road Performance — Metal driveshafts handle the demands of rough terrain, jumps, and aggressive driving much more effectively than plastic components. If you regularly take your Grom or Granite off-road, this upgrade is highly recommended.
Technical Performance
The Fastrax metal rear CVD driveshafts represent a meaningful engineering upgrade for the Arrma 1/18 scale platform. Metal construction provides approximately three to five times the durability of plastic components, depending on driving style and terrain. The constant velocity joint technology eliminates the angular velocity errors that can occur with traditional universal joints, resulting in smoother acceleration and more predictable handling characteristics. This is particularly noticeable when the truck is under load during acceleration or when cornering at speed. The upgrade is especially valuable for drivers who regularly engage in high-impact activities such as jumps, rollovers, and aggressive terrain bashing. Fastrax has engineered these shafts to maintain perfect compatibility with the standard Arrma Granite Grom platform, ensuring they function seamlessly with the standard 380-sized brushed motor and existing drivetrain components. The metal construction also dissipates heat more effectively than plastic, helping to maintain optimal operating temperatures during extended driving sessions. Installation is tool-free on most Arrma vehicles, with the shafts simply inserting into the existing hub assemblies and locking in place with no additional fasteners or modifications required.

Frequently Asked Questions
- Which Arrma models do these metal driveshafts fit? — These Fastrax metal rear CVD driveshafts are specifically designed for the Arrma 1/18 Granite Grom range. They are compatible with the C-ARA2102T1 Arrma Granite Grom Mega 380 brushed 4x4 monster truck in blue and red, the C-ARA2102T3 in green, and the C-ARA2102T2 in red. Always verify your exact model number before ordering to ensure compatibility.
- Why upgrade from plastic to metal driveshafts? — Plastic driveshafts are prone to cracking, stripping, and breaking under heavy use, particularly during jumps or aggressive bashing. Metal driveshafts are substantially more durable and can withstand impacts and stress that would destroy plastic components. If you drive your Grom or Granite hard, this upgrade will save you money on replacements and keep your truck on the track or field rather than on the workbench.
- How difficult is installation? — Installation is extremely straightforward. The Fastrax metal rear CVD driveshafts are designed as direct replacements for the standard rear driveshafts on your Arrma Granite Grom. Simply remove the original shafts and insert the new ones into place. No tools, modifications, or additional parts are required. Most users can complete the upgrade in under five minutes per shaft.
- Will these driveshafts improve my truck's performance? — While these shafts won't increase your top speed, they will deliver power more smoothly and consistently thanks to the CVD design. You'll notice improved acceleration response and more predictable handling, especially during cornering and rough terrain driving. The primary benefit is reliability and durability rather than raw speed.
- Are these suitable for beginners? — Yes, absolutely. Upgrading to metal driveshafts is one of the most beginner-friendly performance modifications available for the Arrma Granite Grom. The installation requires no technical knowledge, no special tools, and no modifications to your truck. Even complete beginners can perform this upgrade with confidence.
- How do I know if my driveshafts need replacing? — Signs that your driveshafts need replacement include visible cracks or breaks, grinding or clicking sounds during acceleration, loss of traction in the rear wheels, or the shafts slipping out of the hub assemblies. If you experience any of these symptoms, it's time to upgrade or replace your driveshafts.
