Key Features

• CNC-Machined Precision Engineering — Every rear hub is manufactured using advanced CNC machining processes that guarantee exact tolerances and consistent quality, ensuring perfect fitment to your ARRMA Grom chassis and eliminating the play or slop common in standard plastic components.
• Premium 7075 Aluminium Alloy Construction — Crafted from aerospace-grade 7075 aluminium, this rear hub offers exceptional strength and rigidity whilst maintaining a lightweight profile, delivering the durability needed for demanding RC use without compromising performance.
• Enhanced Durability Under Load — Aluminium construction significantly resists the cracking, warping, and wear that can occur with plastic components, meaning your rear hub will withstand thousands of impacts, high-speed cornering, and aggressive driving without degradation.
• Improved Handling and Response — The rigid design of this CNC-machined hub reduces flex and movement in the rear drivetrain, resulting in more predictable handling characteristics, sharper steering response, and more consistent cornering performance on track or trail.
• Universal Compatibility Across Grom Range — Designed to fit seamlessly on ARRMA Granite Grom 1/18, ARRMA Mojave Grom, and ARRMA Typhon Grom 1/18 models, making this a versatile upgrade if you run multiple Grom platforms in your RC collection.
• Direct Bolt-On Installation — This rear hub is designed as a direct replacement component, requiring no modification to your existing chassis or suspension, making installation straightforward for experienced builders and RC technicians.
• Professional-Grade Quality — VITAVON's reputation for precision engineering and attention to detail means you're investing in a component trusted by competitive RC racers and serious hobbyists throughout Europe and beyond.
• Weight Optimisation — The aluminium construction provides the strength of steel components whilst maintaining a lightweight package, helping to keep your ARRMA Grom's overall weight distribution optimal for better acceleration and agility.

Technical Performance

The VITAVON CNC Alu7075 Rear Hub represents a significant upgrade over standard plastic rear hub assemblies commonly found on stock ARRMA Grom models. Manufactured from 7075 aluminium alloy through precision CNC machining, this component exhibits exceptional rigidity and resistance to deformation under the high loads and impact forces generated during aggressive RC driving. The aerospace-grade aluminium material possesses tensile strength comparable to many steel alloys whilst maintaining a significantly lower density, resulting in a component that is both stronger and lighter than traditional plastic hubs. The CNC manufacturing process ensures tolerances held to within fractions of a millimetre, guaranteeing that when installed, the rear hub maintains perfect axial alignment with minimal runout or wobble. This precision translates directly into improved drivetrain efficiency, as the rear wheels remain perfectly centred within the chassis geometry, reducing friction losses and improving power transmission from the motor through the transmission to the ground. The rigid construction also minimises the flex that occurs in plastic components during hard cornering and aggressive acceleration, allowing the suspension geometry to perform as the designers intended without compromise. For competitive racers, this means lap times can be more consistent and predictable, as the chassis behaviour becomes more linear and responsive to driver inputs. For weekend bashers and casual users, the extended service life of aluminium components compared to plastic means fewer repairs, more time enjoying your ARRMA Grom, and better overall value from your investment in RC equipment. The anodised finish typical of quality aluminium RC components also provides corrosion resistance, helping the hub maintain its appearance and structural integrity even after exposure to wet conditions common in British RC venues. Weighing significantly less than steel alternatives whilst offering superior strength to plastic, this rear hub represents the optimal balance of performance, durability, and weight management for 1/18 scale RC vehicles like the ARRMA Grom series.

Frequently Asked Questions

• Is this VITAVON rear hub compatible with all ARRMA Grom models? — Yes, this CNC Alu7075 rear hub is specifically designed to fit ARRMA Granite Grom 1/18, ARRMA Mojave Grom, and ARRMA Typhon Grom 1/18 models. Before purchasing, verify your exact Grom variant to ensure compatibility, as the part is engineered specifically for these 1/18 scale platforms.
• What advantages does this aluminium hub offer over the standard plastic component? — The CNC-machined 7075 aluminium construction provides superior durability, enhanced rigidity, improved precision, and extended service life compared to stock plastic hubs. Aluminium resists cracking and warping under stress, maintains tighter tolerances that improve handling, and can withstand significantly more impacts before requiring replacement. For serious RC enthusiasts investing in their vehicles, this upgrade delivers measurable improvements in reliability and performance.
• Will upgrading to this rear hub improve my ARRMA Grom's handling? — Yes, the rigid aluminium construction reduces flex in the drivetrain, resulting in more predictable handling characteristics and sharper steering response. By minimising play and wobble in the rear hub assembly, the suspension geometry performs more consistently, leading to improved cornering precision and more linear chassis behaviour during aggressive driving manoeuvres.
• Is installation difficult for someone new to upgrading RC cars? — This is a direct replacement component that bolts in place of the standard rear hub, requiring no chassis modifications or special tools. However, it is recommended that installation be performed by someone with basic RC maintenance knowledge. If you're unfamiliar with disassembling and reassembling RC drivetrain components, our team at RC Model Shop can provide guidance or installation support.
• How much weight does this aluminium hub add compared to the plastic original? — The 7075 aluminium construction is significantly denser than plastic, meaning this component will weigh more than the OEM plastic hub. However, the overall weight addition is modest and is offset by improved durability and performance benefits. For most RC drivers, the performance gains from reduced flex and improved precision outweigh the marginal weight increase.
• What makes CNC machining superior to injection moulding for RC components? — CNC machining produces components with precision tolerances measured in fractions of a millimetre, whereas injection-moulded plastic components have broader tolerances due to material shrinkage and manufacturing limitations. This precision results in better fitment, reduced play, and more consistent performance across every unit produced. Additionally, aluminium material is inherently stronger and more durable than plastic when subjected to impact and stress.
• Will this rear hub improve my lap times at RC racing events? — For competitive racing, this upgrade can contribute to improved lap consistency by providing more predictable handling and reduced play in the drivetrain. Combined with other performance upgrades and driving skill development, this rear hub is one component in a comprehensive performance optimisation strategy. Results will vary depending on your driving technique, track conditions, and other vehicle setup factors.
• Is the VITAVON rear hub suitable for beginners? — This component is ideal for beginners who want to upgrade their ARRMA Grom's durability and reliability. The direct bolt-on installation requires only basic mechanical knowledge, and the improved durability means fewer repairs and longer intervals between maintenance. However, beginners should ensure they have basic RC maintenance skills or access to guidance before attempting installation.
