Overview
The VITAVON CNC Alu 7075 V2 Rear Hub for ARRMA BLX4S Kraton and Outcast is a precision-engineered upgrade component designed for RC enthusiasts looking to enhance their 1/10 scale electric RC buggy or short course truck. Whether you're a serious basher pushing your brushless RC car to the limit or someone exploring the world of RC vehicles for the first time, this rear hub represents a significant upgrade from standard plastic components. VITAVON has built a reputation for manufacturing high-quality CNC-machined aluminium parts that transform RC performance, and this V2 rear hub exemplifies that commitment to excellence. The use of aerospace-grade 7075 aluminium alloy ensures durability, precision and reliability that RC enthusiasts across the UK have come to trust.
This is a genuine replacement part specifically engineered for ARRMA's BLX4S platform, including both the legendary Kraton 4S and the capable Outcast 4S models. If you own either of these 4S LiPo-powered machines, upgrading your rear hub assembly is one of the most impactful modifications you can make. The V2 designation indicates this is the second generation of VITAVON's design, incorporating lessons learned and refinements from the original V1 hub. It's important to note that this hub is exclusively for V2 models and will not fit V1 variants, so checking your vehicle's generation before purchasing is essential.
As a UK RC car retailer, we understand that RC enthusiasts demand products that deliver real performance gains, not just cosmetic changes. This rear hub addresses multiple needs simultaneously: it provides superior strength compared to the standard plastic hub, maintains precision engineering tolerances that keep your steering and acceleration consistent, and presents an investment in longevity. When you're bashing your RC short course truck or crawler through muddy terrain, pushing your drift car through tight courses, or running scale competitions, having confidence in your vehicle's structural integrity matters enormously.
Key Features
- CNC-Machined 7075 Aluminium Construction — This hub is manufactured from aircraft-grade 7075 aluminium alloy using precision CNC machining, which delivers exceptional strength-to-weight ratio and dimensional accuracy that plastic components simply cannot match, ensuring your rear hub maintains perfect geometry even under extreme driving conditions.
- V2 Generation Design — This is the second-generation design incorporating VITAVON's continuous improvement philosophy, meaning you benefit from refinements and optimisations that address real-world usage patterns that the V1 generation revealed.
- Direct ARRMA Compatibility — Engineered specifically for ARRMA BLX4S vehicles including both the Kraton 4S and Outcast 4S models, ensuring perfect fitment and optimal performance integration with your existing drivetrain and suspension geometry.
- Original Replacement Part — This component directly replaces the original ARRMA part number AR330522, making it a genuine upgrade path that respects your vehicle's original engineering while delivering enhanced durability and reliability.
- Included Assembly Hardware — The hub comes complete with all necessary screws and fasteners required for installation, eliminating the need to source additional components and ensuring you have everything required for immediate fitment.
- Silver Anodised Finish — The silver colour coating not only looks professional and matches modern RC aesthetics, but the anodising process also provides corrosion resistance and protection against the elements, important when running your RC buggy through wet terrain common in UK climates.
- Precision Engineering for Multiple Vehicle Types — Whilst designed for buggy and short course truck applications, this hub's strength and precision make it equally suitable for crawlers, drift cars, and scale vehicles, offering versatility across different RC disciplines.
Technical Performance
The VITAVON CNC Alu 7075 V2 Rear Hub represents a substantial step up from plastic hub components in almost every measurable way. By utilising 7075 aluminium alloy—the same material used in aircraft structures due to its exceptional strength and fatigue resistance—VITAVON ensures that your rear hub can handle the punishment of aggressive driving without flex, bend, or permanent deformation. This is particularly important on a 1/10 scale electric RC vehicle where the rear hub carries the entire rear axle assembly, wheels, tyres, and is subject to enormous lateral forces during high-speed cornering and aggressive acceleration. The CNC machining process creates perfectly perpendicular mounting surfaces and precisely toleranced bearing bores, which means your drivetrain maintains optimal alignment. This alignment precision directly translates to better handling characteristics, more consistent steering response, and reduced wear on your bearings and axles. The engineering of this component reflects VITAVON's understanding that RC performance depends on the accumulation of small improvements across many components—when your hub maintains perfect geometry, your suspension geometry stays true, your differential engages smoothly, and your entire vehicle responds predictably. The original AR330522 part number compatibility ensures this hub integrates seamlessly with all other ARRMA components on your Kraton 4S or Outcast 4S, maintaining the geometric relationships that ARRMA's engineers optimised during vehicle development.

Frequently Asked Questions
- Is the VITAVON V2 Rear Hub compatible with my ARRMA vehicle? — This hub is specifically designed for ARRMA BLX4S models, including both the Kraton 4S and Outcast 4S. It will not fit other ARRMA platforms or V1 generation BLX4S vehicles. If you own an Outcast 4S or Kraton 4S and it's a V2 generation model, this hub is the correct replacement part.
- What's the difference between V1 and V2 versions? — The V2 is the second-generation design from VITAVON, incorporating refinements and improvements over the original V1 design. The V2 addresses real-world usage feedback and represents the current best-practice hub design. You must verify that your vehicle is V2 before ordering, as the V1 and V2 are not interchangeable.
- Why should I upgrade from the standard plastic hub? — Plastic hubs flex under load, which compromises steering precision, causes alignment issues, and can crack under impact or hard driving. This CNC-machined aluminium hub maintains perfect rigidity, ensuring consistent performance lap after lap, reducing drivetrain wear, and providing peace of mind during aggressive RC driving sessions.
- Will this hub work with my existing drivetrain? — Yes, this hub is engineered as a direct replacement for the original ARRMA part (AR330522), so it interfaces perfectly with your existing axles, bearings, brakes, and drive shafts. No modification to other components is necessary.
- Do I need special tools to install this hub? — Installation requires basic RC maintenance tools—a hex driver set and possibly a small screwdriver for the fasteners provided. The actual installation process is straightforward as this hub is a direct swap for the original component. If you're unfamiliar with RC maintenance, visit an RC club or experienced RC friend for guidance.
- Is this suitable for beginners? — Whilst beginners can certainly benefit from upgrading to this hub (particularly if they bash aggressively), this is more of an intermediate upgrade suited to drivers who've already familiarised themselves with basic RC maintenance and want to improve their vehicle's durability and performance.
- How long does this hub last? — The 7075 aluminium alloy is extraordinarily durable. With proper maintenance (cleaning and occasional re-tightening of fasteners), this hub should provide years of reliable service. The main wear items will be the bearings inside, which are replaceable separately.
