Overview
The Fastrax Arrma Grom/Granite Aluminium Front Upper Arms (PR) FTAR050BK are precision-engineered suspension components designed specifically for the Arrma 1/18 Granite Grom monster truck platform. These front upper arms represent a direct upgrade path for RC enthusiasts in the UK looking to enhance their vehicle's performance and durability. Whether you're a seasoned RC car enthusiast or someone discovering the world of dedicated RC upgrades for the first time, these replacement arms offer a significant performance improvement over standard plastic components, making them an essential addition to any serious basher's spares collection.
Built from high-quality aluminium, these front upper arms deliver superior strength and rigidity compared to factory plastic alternatives, translating directly into improved handling characteristics and extended component lifespan. The Arrma Grom has become an incredibly popular ready to run RC monster truck choice for UK buyers, and the availability of quality upgrade parts like these demonstrates the strong aftermarket support this platform enjoys. Fastrax has built a reputation for manufacturing durable, reliable suspension components, and these arms continue that tradition with materials and engineering designed to withstand the demands of serious off-road bashing and racing alike.
As a pair of front upper arms, this product provides the essential suspension linkage your Granite Grom needs to maintain optimal geometry and response under load. The move from plastic to aluminium upper arms is one of the most impactful suspension upgrades you can make on this platform, improving both the car's handling precision and its ability to absorb impacts during aggressive driving. RC Model Shop stocks this product from Fastrax, ensuring you're getting genuine, authentic components with full manufacturer backing and support.
Key Features
- Aluminium Construction — These front upper arms are manufactured from high-quality aluminium rather than plastic, providing dramatically improved strength, rigidity and durability that directly translates to better handling and longer service life in demanding conditions.
- Precision Engineering — Fastrax has designed these arms with exact specifications to maintain perfect suspension geometry on the Arrma Grom and Granite platforms, ensuring predictable handling characteristics and consistent performance across different driving styles and terrain types.
- Factory Fitment — These arms are engineered to be direct replacements for the stock plastic components, meaning installation is straightforward and requires no modification to your vehicle, getting you back on the track or trails quickly.
- Pair Included — This product comes as a complete pair of front upper arms (left and right), providing everything needed for a full front suspension refresh on your Arrma Granite Grom.
- Performance Upgrade — Upgrading to aluminium suspension arms is one of the most recognised performance modifications for RC monster trucks in the UK, improving steering response, cornering stability and impact absorption during high-speed runs and rough terrain driving.
Technical Performance
The Fastrax Arrma Grom/Granite Aluminium Front Upper Arms represent a significant step up in suspension component quality for this popular 1/18 scale platform. The choice of aluminium as the primary material is crucial to understanding these arms' performance benefits—whilst plastic components can flex and wear over time, aluminium maintains its shape and rigidity under repeated stress, translating to more consistent handling lap after lap. The manufacturing process ensures tight tolerances throughout, maintaining the suspension geometry that Arrma engineers designed into the Granite Grom platform. When paired with quality bearing upgrades and other suspension modifications, aluminium arms form the foundation of a track-focused setup capable of delivering the precision handling that RC enthusiasts demand. For bashers who prioritise durability and reliability in rough terrain, these arms significantly reduce the frequency of suspension component failures, keeping your vehicle in action rather than on the workbench. The upgrade is particularly beneficial for high-speed running where suspension stiffness becomes increasingly important for maintaining predictable handling characteristics.

Frequently Asked Questions
- Are these aluminium front upper arms compatible with my Arrma Granite Grom? — Yes, these Fastrax FTAR050BK arms are specifically engineered as direct replacements for the Arrma 1/18 Granite Grom Mega 380 brushed 4x4 monster truck, regardless of the colour variant (Blue/Red, Green, or Red versions). They simply bolt in place of the factory plastic components with no modifications required.
- What is the main advantage of upgrading to aluminium from plastic upper arms? — Aluminium arms provide several key benefits: superior strength that reduces breakage risk during impacts and hard landings, improved rigidity that sharpens handling response and cornering precision, and longer durability that means fewer replacements over time. For RC car enthusiasts in the UK looking to maximise their vehicle's performance and reliability, this is one of the most cost-effective upgrades available.
- Will these arms fit both the Granite and Grom versions? — Yes, these arms are compatible with both the Arrma Granite Grom platform variants, making them a versatile upgrade choice if you own either model or plan to use them across multiple vehicles.
- Do I need any special tools to install these front upper arms? — Installation requires only standard RC tools you likely already own—basic hex wrenches and possibly a socket set for the ball joints. The job is straightforward enough for intermediate builders, taking just 15-20 minutes per side to complete the upgrade.
- What is the difference between these Fastrax arms and factory Arrma plastic arms? — The fundamental difference is material: Fastrax uses engineered aluminium alloy whilst Arrma's stock components are injection-moulded plastic. This means Fastrax arms are stiffer, more durable, more resistant to impact damage, and maintain their suspension geometry more consistently over extended use, making them the preferred choice for serious RC enthusiasts.
