Overview
The Fastrax Arrma Grom/Granite Aluminium Steering Rod Arms represent a premium upgrade for your 1/18 scale RC monster truck. Whether you're an experienced RC enthusiast looking to enhance your Arrma Grom or Granite's handling characteristics, or a dedicated basher seeking improved steering precision, these aluminium steering rod arms deliver the durability and performance upgrade your vehicle deserves. As a UK RC hobby retailer, we recognise that investing in quality replacement parts is essential for maintaining your RC car UK collection in peak condition, and these Fastrax parts are engineered to provide years of reliable service.
Steering geometry is critical to the performance of any RC vehicle, and the stock plastic steering arms can wear or flex under aggressive driving conditions. These aluminium alternatives from Fastrax offer a substantial improvement in rigidity and longevity, ensuring your steering input remains precise and responsive lap after lap. Whether you're running your brushless RC monster truck on the track or enjoying casual weekend bashing sessions, upgrading to aluminium steering rod arms is one of the most cost-effective performance modifications you can make. The Fastrax brand has built a strong reputation within the RC community for producing high-quality, durable upgrade parts that genuinely enhance vehicle performance and lifespan.
Compatible with both the Arrma 1/18 Granite Grom Mega 380 Brushed 4x4 Monster Truck RTR models (available in blue/red, green, and red variants), these steering rod arms are a direct fit replacement that requires no modification or additional components. The pair format means you're receiving both left and right steering arms in a single convenient package, making this an ideal single-purchase upgrade that takes your RC car's steering performance to the next level.
Key Features
- Aluminium Construction — Manufactured from premium-grade aluminium rather than plastic, these steering rod arms provide significantly greater rigidity and resistance to bending under load, ensuring your steering inputs translate directly to predictable vehicle behaviour even during aggressive cornering or off-road bashings.
- Precision Engineering — Fastrax parts are designed and manufactured to exacting tolerances, guaranteeing perfect fitment with your Arrma Grom or Granite without any modification, shimming, or adjustment required during installation.
- Pair Format — This package includes both left and right steering rod arms, providing a complete steering upgrade solution in one purchase rather than requiring separate orders for each side.
- Direct Replacement Design — These arms are engineered as a direct replacement for the stock plastic components, meaning they install using your existing fastening points and require no additional hardware or modifications to your vehicle's steering linkage.
- Durability Enhancement — Aluminium steering arms resist the flexing and wear that occurs with plastic alternatives, dramatically extending the service life of your steering system and reducing the frequency of replacement part purchases over time.
- Performance Consistency — The rigid construction maintains steering geometry under all driving conditions, preventing the gradual steering drift that can occur as plastic arms wear or flex during extended driving sessions.
Technical Performance
These Fastrax steering rod arms represent a significant engineering upgrade from the stock plastic alternatives found on the Arrma 1/18 Granite Grom Mega 380 Brushed 4x4 Monster Truck RTR. The material science behind this upgrade is straightforward: aluminium exhibits a modulus of elasticity approximately three times greater than engineering-grade plastic, meaning the arms resist bending and flexing under the steering loads generated during spirited driving. This rigidity directly translates to more responsive steering feel, improved turn-in precision, and greater consistency throughout a driving session. The aluminium used in Fastrax components is typically 6061-T6 or similar aerospace-grade alloy, which balances weight savings with exceptional strength characteristics. For the 1/18 scale Arrma platform, this weight consideration is particularly important—whilst the aluminium arms are heavier than plastic alternatives, the mass difference is negligible at this scale, adding perhaps 2-3 grams per arm, yet providing measurable improvements in steering precision. The manufacturing process utilises CNC machining to ensure each arm meets exact dimensional specifications, guaranteeing that left and right arms are perfectly matched for balanced steering geometry. Installation is straightforward, utilising the same mounting points as the original plastic arms and requiring only standard RC tools such as a hex wrench set, which most RC enthusiasts already maintain in their tool collection. The arms are designed to work seamlessly with the standard servo system and linkage geometry of the Arrma Grom and Granite platforms, requiring no modifications to steering trim or servo settings.

Frequently Asked Questions
- Are these steering arms compatible with all Arrma Grom and Granite models? — These Fastrax aluminium steering rod arms are specifically engineered for the Arrma 1/18 Granite Grom Mega 380 Brushed 4x4 Monster Truck RTR platform, and are confirmed compatible with all three colour variants: the blue/red (C-ARA2102T1), green (C-ARA2102T3), and red (C-ARA2102T2) versions. They are direct replacements for the stock plastic steering arms and require no modification to install.
- What are the advantages of upgrading from plastic to aluminium steering arms? — Aluminium steering arms offer several key advantages over stock plastic components: they resist flexing under load, maintain steering geometry more precisely during aggressive driving, resist wear and degradation from UV exposure and heat cycling, and last significantly longer before requiring replacement. For any RC car UK owner who drives their vehicle regularly, upgrading to aluminium arms is one of the most effective performance modifications available.
- Will upgrading to these steering arms improve my handling? — Yes, these aluminium steering rod arms will improve handling consistency by eliminating the flex present in stock plastic arms. You'll notice more responsive steering feel, better turn-in precision, and more predictable cornering behaviour. The improvement is subtle but noticeable, especially during rapid directional changes or aggressive off-road bashings where the stock plastic arms are prone to flexing.
- Are these arms difficult to install? — Installation is straightforward and requires only basic RC tools. The arms use the same mounting points as the original plastic components, so no modification to your vehicle is necessary. Installation typically takes 5-10 minutes per side using standard hex wrenches. No special knowledge or experience is required.
- Will I need to adjust my servo trim after installing these arms? — No adjustment to servo trim or steering settings is required. These arms are engineered as direct replacements that maintain the original steering geometry, so your vehicle will drive exactly as it did with the stock plastic arms, but with improved precision and durability.
- How do these compare to other aftermarket steering arm options? — Fastrax is a recognised manufacturer specialising in high-quality RC upgrade parts. These arms are manufactured to precise specifications using quality materials, and represent excellent value for money when compared to other premium aftermarket steering solutions available for the Arrma platform.
