Overview
Upgrade your 1/18 scale RC buggy or monster truck with the RC Overhaul Front Hubs in striking red aluminium. Whether you're running an Arrma Granite Grom or Typhon Grom, these precision-machined front hubs are the perfect enhancement for any serious basher. If you're looking to improve the durability and reliability of your RC car UK setup, these hubs deliver both performance and aesthetics in one affordable upgrade. The stock hubs (ARA330807) can take plenty of punishment, but over time they flex and weaken with repeated bashing. These RC Overhaul hubs eliminate that flex, giving you the confidence to push your vehicle harder without worrying about component failure.
Designed specifically for the 1/18 scale Grom platform, these front hubs are manufactured from quality aluminium and anodised in red to perfectly complement your vehicle's factory colour scheme and other factory accents. This is not just a performance upgrade—it's a visual one too. When fitted to your GROM, these hubs blend seamlessly with the existing design, maintaining that clean, factory-style appearance whilst delivering noticeably improved strength and durability. For weekend bashers, regular competitors, and anyone serious about keeping their RC vehicle on the track or bashing course rather than in the workshop, this is an essential upgrade.
RC Overhaul has built a reputation for producing quality aftermarket components that enhance reliability without compromising aesthetics. The machined aluminium construction means these hubs won't let you down when you need them most, offering a tougher, more stable alternative to the original plastic units. At just £22.99, this represents outstanding value for money and is the kind of inexpensive hop-up that makes a tangible difference to your RC experience.
Key Features
- Precision-Machined Aluminium Construction — These front hubs are CNC machined from quality aluminium, delivering superior strength and durability compared to the factory plastic originals. Machined components are held to tight tolerances, ensuring perfect fitment and consistent performance across multiple vehicles.
- Anodised Red Finish — The hubs are anodised in red to match the other details and factory accents in your Arrma GROM vehicle, creating a cohesive and professional appearance when fitted. The anodised coating also provides corrosion resistance and colour longevity.
- Reduced Flex and Improved Steering Stability — By eliminating the flex found in stock plastic hubs, these aluminium components help maintain consistent steering performance even during aggressive bashing sessions, giving you more predictable handling and better control.
- Enhanced Bash-Ability and Long-Term Reliability — These hubs are built to withstand the rigours of regular RC bashing and competition use. They significantly extend the lifespan of your drivetrain by reducing stress on other components and preventing premature wear caused by hub flex.
- Direct Replacement for Stock Part ARA330807 — These hubs are a plug-and-play upgrade that replaces the front hubs found in the original Arrma pack ARA330807. No modification is required, making installation straightforward for most RC enthusiasts.
- Inexpensive Upgrade Solution — At £22.99, this represents excellent value as a hop-up upgrade that noticeably improves vehicle performance and reliability without breaking the bank.
- Compatible with Multiple Grom Variants — These hubs work with both the Granite Grom and Typhon Grom platforms across multiple colour variants, making them a versatile upgrade option for the entire 1/18 Grom product range.
Technical Performance
The RC Overhaul Front Hubs represent a significant step forward in chassis durability for 1/18 scale RC enthusiasts in the UK. Machined from quality aluminium rather than the plastic used in factory units, these hubs deliver noticeably superior rigidity and strength. The precision machining process ensures that each hub meets tight tolerances, resulting in perfect fitment when replacing the original ARA330807 components. Aluminium's inherent properties make it far less prone to flex during cornering, acceleration, and impacts—common scenarios during aggressive RC bashing. This reduction in flex directly translates to more consistent steering response and improved handling characteristics. The anodised red finish not only matches the vehicle's aesthetic but also provides a protective oxide layer that resists corrosion and wear from dirt, moisture, and repeated use. For bashers running their vehicles regularly, the improved durability of aluminium hubs means fewer component failures, less downtime, and more reliable performance session after session. The engineering behind these hubs recognises that front suspension geometry depends on rigid mounting points; when hubs flex, suspension geometry changes, affecting how the vehicle handles. By providing a solid, unyielding mounting point, these hubs ensure that your suspension works as designed, delivering the handling characteristics you've come to expect from your Grom.

Frequently Asked Questions
- Are these RC Overhaul front hubs suitable for bashers and beginners? — Absolutely. These hubs are particularly well-suited to bashers and regular drivers who want to improve their vehicle's durability and reliability. Because they're a straightforward drop-in replacement with no special knowledge required to install, even beginners can upgrade their Grom. The improved durability means fewer component failures and less time spent repairing, allowing you to spend more time driving.
- Will these hubs fit my Arrma GROM? — Yes, these RC Overhaul front hubs are specifically designed for 1/18 scale Grom variants. They're compatible with the Arrma 1/18 Granite Grom Mega 380 (all colour variants including Blue/Red, Green, and Red) and the Arrma 1/14 Typhon Grom Mega 380 (Blue/Silver and Red/White). They directly replace the factory part ARA330807 with no modification needed.
- What makes aluminium hubs better than the plastic originals? — Aluminium is significantly stronger and more rigid than plastic, and it doesn't flex under load the way plastic hubs do. When your Grom's plastic hubs flex, it changes your suspension geometry and handling characteristics. Aluminium hubs maintain rigid geometry, ensuring consistent steering response and handling. Additionally, aluminium resists fatigue and cracking far better than plastic, extending the lifespan of your front end considerably. For regular bashers, the difference in durability is night and day.
- Do I need any special tools to install these hubs? — Installation is straightforward and requires only standard RC tools you likely already have. Remove the old hubs from the suspension carriers and install these new ones using the existing mounting points and screws. Thread lock on the fixing screws is recommended to prevent them coming loose during aggressive driving.
- Will these improve my GROM's handling? — Yes. By eliminating hub flex, these aluminium components allow your suspension to maintain its designed geometry throughout corners, acceleration, and impacts. This results in more predictable and responsive handling, particularly noticeable during aggressive bashing or competitive driving.
- Are these front hubs anodised and corrosion-resistant? — Yes, the hubs are anodised in red, which provides both the colour match to your vehicle and a protective oxide layer that resists corrosion from dirt, moisture, and repeated use. This means they'll maintain their appearance and performance for years of bashing.
- What is the difference between these RC Overhaul hubs and aftermarket alternatives? — RC Overhaul hubs are precision-machined to tight tolerances, ensuring perfect fitment and consistent performance. The quality of the machining and the grade of aluminium used make a significant difference in durability and performance. Many budget alternatives use lower-grade materials or looser tolerances, which can result in fitment issues or premature wear. RC Overhaul's reputation is built on delivering quality components that last.
