Overview
The RC Overhaul Metal Differential Hub 4pcs set (G-RCO-AR010) is an essential upgrade for owners of Arrma 1/18 Granite Grom and 1/14 Typhon Grom RC vehicles. If you've damaged your standard plastic differential outdrives, this metal replacement set offers a cost-effective solution that gets you back on the track without the expense of replacing your entire differential assembly. Whether you're a weekend basher enjoying RC car UK entertainment or a serious hobbyist pushing your vehicle to its limits, differential hubs are critical components that endure significant stress during acceleration, cornering and aggressive driving.
Designed and manufactured by RC Overhaul, this four-piece metal hub set directly replaces the factory plastic outdrives, transforming your differential from a potential weak point into a significantly stronger, more durable component. The shift from plastic to metal construction delivers measurable improvements in reliability and longevity, particularly if you frequently tackle rough terrain, perform high-speed runs or engage in competitive racing with your Grom model. This is the kind of upgrade that serious ready to run RC enthusiasts make when they want to extract maximum performance and durability from their investment.
Unlike purchasing an entirely new differential unit, this targeted upgrade approach is both economical and practical. You retain your existing differential housing and internal components while reinforcing the output points where power is transferred to your drive shafts. For RC vehicle owners in the UK looking to strengthen their drivetrain without breaking the bank, the RCO Metal Differential Hub set represents genuine value and proven performance improvement.
Key Features
- Metal Construction for Superior Durability — Unlike the standard plastic outdrives that come factory-equipped on your Grom, these metal hubs offer dramatically improved strength and resistance to wear, meaning they'll withstand the punishment of regular bashing, racing and high-torque driving conditions far better than plastic alternatives.
- Direct Replacement Design — These hubs are engineered to fit perfectly into your existing differential assembly without requiring modification to your vehicle, making installation straightforward and hassle-free for owners with basic RC maintenance knowledge.
- Eliminates the Need for Full Differential Replacement — If you've only damaged the plastic outdrives, swapping in this metal set means you can avoid the significant cost and inconvenience of purchasing and installing a completely new differential unit, saving you both time and money.
- Pack of Four Hubs — This set includes all four differential hubs you need to completely restore your drivetrain, ensuring consistent performance across all drive outputs.
- Enhanced Drive Reliability — Metal construction reduces flex and distortion under load, meaning power delivery becomes more consistent and predictable, particularly noticeable when accelerating hard or navigating technical terrain.
- Proven RC Overhaul Quality — RC Overhaul is a recognised manufacturer of RC upgrade parts and tuning components, bringing engineering expertise and quality control to every product they produce.
Technical Performance
The RCO Metal Differential Hub set addresses a common durability concern in RC vehicles across the UK and beyond. The differential is the component responsible for distributing engine power to the drive wheels whilst allowing them to rotate at different speeds during cornering — a critical function that places significant mechanical stress on the output hubs. Factory plastic outdrives, whilst acceptable for casual driving, can crack, strip or deform under sustained acceleration, hard cornering or when tackling rough terrain. By switching to metal construction, you gain several measurable performance benefits: increased stiffness reduces drivetrain slop and improves power transmission efficiency; enhanced durability extends the service life of your differential significantly; and improved consistency ensures that your vehicle behaves predictably lap after lap or run after run. The metal material resists the flex that can cause plastic components to wear prematurely or fail suddenly, and it handles the repetitive stress cycles of RC driving far more effectively. This is particularly important if you're running your Grom with upgraded motors, ESCs or LiPo battery packs that deliver more torque and acceleration than factory specifications. The engineering principle is straightforward: stronger materials equal longer component lifespan and more reliable performance, which is why experienced RC enthusiasts across the UK routinely upgrade to metal drivetrain components as their first maintenance and performance enhancement.

Frequently Asked Questions
- Which RC vehicles are compatible with the RC Overhaul Metal Differential Hub 4pcs set? — These hubs are specifically designed for Arrma 1/18 Granite Grom models (available in Red, Blue/Red, and Green colour variants) and the Arrma 1/14 Typhon Grom (Blue/Silver and Red/White colour options). Compatibility is confirmed with the following models: C-ARA2102T2, C-ARA2102T1, C-ARA2102T3, C-ARA2106T1, and C-ARA2106T2. If you own a different Arrma model or vehicle from another manufacturer, these hubs will not fit.
- Do I need any special tools or technical expertise to install these metal hubs? — Installation requires basic RC maintenance skills and standard RC tools. You'll need to access your differential assembly, which typically involves removing the vehicle's suspension and chassis components. If you're familiar with RC car maintenance and have successfully serviced your Grom before, you should find installation straightforward. Many RC hobbyists in the UK perform this type of work themselves, though you can always consult your vehicle's manual or contact RC Model Shop for guidance.
- Why should I upgrade to metal differential hubs instead of buying a new differential? — Metal hub replacement is a cost-effective targeted upgrade that makes sense if your plastic outdrives are damaged but your differential housing and internal components are in good condition. A complete differential replacement is significantly more expensive and requires removing and reinstalling more components. By upgrading just the hubs, you preserve your existing differential investment whilst gaining the durability benefits of metal construction at a fraction of the cost.
- Will metal differential hubs improve the performance of my RC Grom? — Metal hubs won't increase your top speed or acceleration, but they will improve drivetrain reliability and consistency. You'll notice more predictable power delivery, reduced drivetrain slack, and increased durability during high-torque driving conditions. If you frequently experience plastic hub damage or wear, switching to metal will virtually eliminate that problem, allowing you to focus on driving rather than repairs.
- How do these compare to the factory plastic outdrives? — The key difference is material: metal provides superior strength, rigidity and wear resistance compared to plastic. Plastic outdrives are adequate for casual driving but can crack, flex or strip under stress. Metal construction resists deformation, lasts significantly longer, and maintains consistent performance throughout its service life. If you regularly bash your Grom hard or run upgraded powertrains, metal hubs are a worthwhile upgrade.
- Is this suitable for beginners? — These are replacement parts rather than complete vehicles or ready-to-run kits, so they're intended for RC enthusiasts who already own a compatible Grom model and have basic maintenance skills. If you're new to RC cars and own a Grom, these parts represent a sensible investment for improving durability, but you should have some familiarity with basic vehicle maintenance before attempting installation.
