Whether you're a seasoned RC car UK competitor or a weekend basher, this hub set delivers the reliability needed to keep your MOJAVE GROM performing at its best. The GROM has earned its reputation as one of the most capable small-scale RC trucks available, and maintaining it with genuine ARRMA replacement parts ensures consistent performance and longevity. This composite hub set is engineered to withstand the rigorous demands of extreme RC action, from high-speed desert runs to technical course work.
If you've experienced hub damage from crashes, impacts, or general wear and tear, the ARRMA Hub Set B provides a straightforward replacement solution that restores your truck to factory specifications. RC enthusiasts appreciate the ready-to-run nature of ARRMA vehicles, and the availability of genuine spare parts means you can keep your investment performing like new. The precision-engineered design ensures that your suspension geometry remains true, which directly impacts handling, stability, and overall driving experience. This is not just a cosmetic replacement — it's a critical component of your truck's suspension system that affects everything from cornering behaviour to jump landing characteristics.
The Hub Set B covers both front and rear hubs in a single package, making it the logical choice for comprehensive maintenance or rebuilding. Available at RC Model Shop, this authentic ARRMA component is backed by the manufacturer's quality standards and engineering expertise. Whether you're preparing for competitive racing, casual bashing, or simply maintaining your fleet, investing in genuine ARRMA replacement parts like this hub set demonstrates a commitment to getting the most out of your RC investment.
Key Features
- Tough Composite Material — The hub set is constructed from high-quality composite material that provides increased crash resistance compared to weaker alternatives. This durability is crucial for RC enthusiasts who subject their vehicles to demanding terrain and impacts, as the material absorbs shock energy without shattering or deforming permanently, extending the usable life of the component.
- Precision Molding — Each hub is manufactured using precision molding techniques that ensure smooth suspension operation in all conditions. This precision is essential for maintaining consistent handling characteristics, as any deviation in hub geometry can cause steering bind, alignment issues, or unpredictable suspension response, particularly noticeable during high-speed cornering or technical driving.
- Front and Rear Coverage — The set includes both front and rear hubs, providing a complete solution for full-vehicle maintenance or repair. This comprehensive approach means you can replace both front and rear components as a matched set, ensuring symmetrical suspension behaviour and consistent performance across the entire truck.
- King Pin Screws Included — Four king pin screws are supplied with the hub set, ensuring you have all the fastening hardware needed for installation. King pins are critical for proper hub assembly and bearing retention, so including quality fasteners eliminates the need to source these components separately and ensures proper assembly specifications.
- Genuine ARRMA Component — As an official ARRMA replacement part, this hub set meets all the manufacturer's engineering specifications and quality standards. Using genuine components ensures compatibility, reliability, and performance that matches the original design intent of your MOJAVE GROM.
Technical Performance
The ARRMA Hub Set B is engineered specifically for the 1/16 scale MOJAVE GROM and compatible models, delivering the structural integrity and dimensional precision required for optimal suspension performance. The composite material selected for this component represents a balance between durability and weight, providing exceptional crash resistance that absorbs impacts from jumps, collisions, and rough terrain without permanent deformation. The precision molding process ensures that each hub maintains exact specifications for bearing fitment, steering geometry, and suspension alignment — factors that directly influence how your RC car performs during acceleration, cornering, and braking. The material composition chosen by ARRMA engineers has been proven through extensive testing to withstand the extreme stresses of high-speed running, repeated impacts, and harsh environmental conditions that UK RC enthusiasts encounter when bashing their vehicles outdoors. The inclusion of four king pin screws with the set demonstrates ARRMA's commitment to providing a complete, install-ready package that requires no additional sourcing or guesswork during assembly.

Frequently Asked Questions
- What is a hub and why would I need to replace it on my RC car? — A hub is the central component of the wheel assembly that connects the suspension components to the wheel and tyre. Over time, hubs can crack, wear, or suffer impact damage from crashes or rough driving conditions. Replacing damaged hubs restores proper wheel alignment, suspension geometry, and handling characteristics. If your GROM's steering feels loose, the wheels don't sit true, or you've experienced a significant impact, a hub set replacement may be necessary to maintain safe, predictable performance.
- Is this hub set suitable for both beginners and experienced RC drivers? — Absolutely. Whether you're new to the RC hobby or an experienced RC car UK enthusiast, maintaining your truck with genuine replacement parts is essential. Beginners benefit from using authentic ARRMA components because they ensure their vehicle performs as designed, whilst experienced drivers appreciate the reliability and consistency that genuine parts provide. Hub replacement is a straightforward maintenance task that most RC enthusiasts can accomplish with basic tools and a little guidance.
- How do I know if my GROM needs new hubs? — Inspect your hubs regularly for visible cracks, splits, or severe wear. Common signs that replacement is needed include loose steering response, wheels that sit at odd angles, suspension that feels sloppy or unpredictable, or obvious impact damage. If you've had a significant crash or noticed any of these symptoms, it's wise to replace the hub set to ensure optimal performance and prevent further damage to related suspension components.
- Are these hubs compatible with other ARRMA models? — No, these hubs are specifically engineered for the 1/16 scale MOJAVE GROM and the compatible models listed in the compatibility section. Different ARRMA models have different suspension geometries and hub dimensions, so always verify compatibility with your specific model before purchasing replacement parts. Using incorrect hubs can result in poor handling, misalignment, and potential suspension damage.
- What is included with this hub set and what else might I need? — The set includes four hubs (two front, two rear) and four king pin screws. You may need additional components depending on the condition of your other suspension parts — such as bearings, axles, or washers — but the hub set itself provides everything specifically included in this product. Check your user manual or consult with RC Model Shop if you're uncertain about what else your truck might need during a rebuild.
- How difficult is it to install these hubs? — Hub replacement is a moderate-difficulty task that requires basic tools such as screwdrivers and possibly a small wrench or hex key set. If you're comfortable with basic RC maintenance and have replaced components before, you should find this straightforward. However, if you're new to RC maintenance, you might benefit from consulting your GROM's instruction manual or watching an online tutorial. RC Model Shop can also provide guidance if you have specific questions about installation.
