This part is easy to install for anyone with basic RC maintenance experience, making it an accessible upgrade for intermediate and advanced RC enthusiasts across the UK hobby market.
Key Features
- Aluminium Construction — Manufactured from lightweight yet rigid aluminium alloy, this rear hub carrier offers substantially greater durability and strength compared to plastic alternatives, reducing the risk of failure during aggressive driving or high-impact collisions typical in RC bashing and off-road use.
- Precision Engineered Design — The component is precisely machined to exact tolerances, ensuring perfect fitment with your Grom or Granite rear suspension system and maintaining the critical geometric angles necessary for optimal handling and tyre wear characteristics.
- Pair Configuration — Supplied as a pair, this product gives you both left and right rear hub carriers, providing complete rear suspension support and allowing for consistent performance across the full width of the vehicle chassis.
- Direct Compatibility — Specifically engineered for the Arrma 1/18 Granite Grom range, including all colour variants of the Mega 380 brushed 4x4 monster truck, ensuring guaranteed fitment without modification or adaptation.
- Enhanced Rigidity — The superior material properties of aluminium compared to plastic reduce flex and deflection under cornering loads and impacts, improving overall chassis stiffness and responsiveness for more predictable handling and better control during fast driving.
- Extended Service Life — Aluminium components resist the stress cracking and brittle fractures that can affect plastic parts over time, meaning this upgrade will maintain its integrity through hundreds of hours of use, delivering better value for money in the long term.
- Easy Installation — As a direct OEM replacement component, the rear hub carrier integrates seamlessly into your existing suspension system with minimal tools and no special knowledge required, making it suitable for anyone with basic RC maintenance experience.
- Professional Grade Quality — The Fastrax brand is recognised across the RC hobby market as a producer of high-quality aftermarket upgrades, and this component reflects that commitment to engineering excellence and attention to detail.
Technical Performance
The Fastrax Arrma Grom/Granite Aluminium Rear Hub Carrier represents a thoughtful engineering solution for the 1/18 scale monster truck category. Constructed from aluminium alloy rather than the plastic found in stock components, this rear hub carrier pair delivers measurable improvements in structural integrity and longevity. The material choice is particularly significant for the rear suspension, where suspension loads, cornering forces, and impact stresses concentrate during dynamic driving. Where plastic components can develop stress cracks, warp under sustained load, or fail catastrophically upon hard impacts, aluminium maintains its dimensional stability and strength across thousands of driving cycles. The precision machining process ensures that the hub carrier geometry remains true and accurate, which is critical for maintaining proper suspension geometry, controlling tyre contact patch, and ensuring consistent handling characteristics across different driving conditions and surfaces. For users of the Arrma 1/18 Granite Grom Mega 380 brushed 4x4 platform, this upgrade delivers noticeable improvements in durability without requiring any modifications to the rest of your setup, making it an excellent value-for-money enhancement that will extend the operational life of your RC investment substantially.

Frequently Asked Questions
- Is this aluminium rear hub carrier compatible with my Arrma Granite Grom? — Yes, the Fastrax FTAR055B is specifically designed for the Arrma 1/18 Granite Grom Mega 380 brushed 4x4 monster truck. It is compatible with all colour variants including the Blue/Red, Green, and Red versions of this popular ready to run RC model.
- What is the advantage of aluminium over plastic hub carriers? — Aluminium offers superior strength-to-weight ratio, greater rigidity, and exceptional durability compared to plastic. Aluminium components resist stress cracking, maintain their shape under load, and can withstand thousands more driving cycles before requiring replacement. For serious RC bashers and users who want their vehicles to last, aluminium is the recognised upgrade choice.
- Will upgrading to these hub carriers improve my Grom's handling? — Yes, aluminium hub carriers will improve overall chassis rigidity and reduce flex during cornering and acceleration, resulting in more responsive steering, better traction control, and more predictable handling characteristics across different surfaces and driving styles.
- Is this suitable for beginners? — The rear hub carrier is a component upgrade that requires basic mechanical knowledge to install, such as removing the rear axles and suspension. Whilst not difficult, it is more suitable for intermediate to advanced RC enthusiasts who have experience maintaining their RC cars. If you're new to RC maintenance, we recommend seeking guidance or having an experienced friend assist with installation.
- Do I need any special tools to install these hub carriers? — Installation requires standard RC maintenance tools including hex drivers and possibly a small screwdriver set. No specialist equipment is necessary, making this a straightforward upgrade for anyone with basic RC service experience.
- What other Fastrax upgrades work well with these rear hub carriers? — The Fastrax Arrma Grom/Granite range includes several complementary upgrades such as aluminium front upper arms (FTAR050R or FTAR050BK) and aluminium rear upper arms (FTAR052BK), which work together to create a fully upgraded aluminium suspension system for improved durability across the entire platform.
