VITAVON CNC Aluminum 7075 Main Chassis 4mm Thickness For Arrma Kraton 6S - Vitavon VITARA320623

Overview

The VITAVON CNC Aluminium 7075 Main Chassis 4mm Thickness is a premium upgrade component for the Arrma Kraton 6S family of RC buggies. This heavy-duty chassis represents a significant step up from the stock 3mm unit, offering enhanced durability and rigidity for drivers who demand maximum performance from their 1/10 scale RC car UK models. Whether you're a competitive racer pushing your Kraton to its limits or a weekend basher looking for a tougher platform that can handle aggressive driving, this precision-engineered chassis delivers the structural integrity you need.

Manufactured by VITAVON, a recognised name in RC performance upgrades, this chassis is machined from aerospace-grade aluminium 7075 using CNC technology to ensure perfect tolerances and consistency. The decision to increase thickness from 3mm to 4mm is not arbitrary—it's a deliberate engineering choice that addresses a common weak point in stock chassis designs. For UK RC enthusiasts running high-powered brushless setups on their 6S LiPo-equipped Kraton models, this upgrade provides the peace of mind that comes with knowing your chassis can handle the punishment that serious RC off-road racing demands.

This main chassis is compatible with multiple variants of the Arrma Kraton 6S platform, including the earlier generation models and the newer EXB ARA8708V5 specification. The compatibility extends to the Arrma Notorious 6S as well, making this a versatile upgrade option for anyone with these vehicles in their collection. Available in both silver and red finishes, you can choose the colour that best suits your aesthetic preferences whilst gaining the same structural benefits.

Key Features

• CNC-Machined Aluminium 7075 Construction — This aerospace-grade aluminium alloy is renowned for its exceptional strength-to-weight ratio and superior fatigue resistance compared to standard aluminium. The CNC machining process ensures that every chassis is manufactured to the same exacting standards, eliminating the dimensional inconsistencies that can occur with injection-moulded alternatives and providing a solid foundation for your RC buggy UK setup.
• 4mm Thickness versus 3mm Stock Chassis — By increasing the chassis thickness by one full millimetre, VITAVON has significantly improved the structural rigidity of the platform. This extra material helps prevent bending and flexing under load, which is particularly important when running powerful brushless motors and demanding 6S LiPo batteries. The result is better handling characteristics, improved durability under stress, and a longer lifespan for your chassis investment.
• Extended Compatibility Range — This chassis fits the original Arrma Kraton 6S (models ARA8608V5T1 and ARA8608V5T2) as well as the newer Kraton 6S EXB ARA8708V5 specification, plus the Arrma Notorious 6S (ARA8611V5T1 and ARA8611V5T2). This broad compatibility makes it an attractive upgrade option for drivers with multiple 6S vehicles or those considering expanding their fleet, as a single upgrade can serve multiple platforms.
• Precision Engineering for Optimal Performance — The CNC manufacturing process guarantees that mounting points are perfectly aligned and dimensional consistency is maintained throughout the part. This precision ensures that your suspension geometry remains accurate, steering response stays predictable, and overall handling maintains the fine-tuned characteristics you've dialled in on your RC model.
• Dual Colour Options — Available in both silver and red finishes, you can select the colour that complements your vehicle's body shell and personal aesthetics. Both finishes utilise the same high-quality aluminium 7075 material and offer identical performance characteristics.
• Direct OEM Replacement — This chassis is designed as a direct replacement for the stock unit, meaning installation is straightforward without requiring modifications to mounting points, suspension components, or other chassis-dependent parts. Simply remove your existing chassis and bolt on the VITAVON upgrade.

Technical Performance

The VITAVON CNC Aluminium 7075 Main Chassis represents a genuine performance upgrade backed by material science and engineering principles. Aluminium 7075 is the choice of aerospace manufacturers and high-performance racing applications for good reason—it offers approximately 73% higher tensile strength than standard 6061 aluminium while maintaining a lighter weight profile than steel alternatives. When VITAVON engineered this chassis for the Arrma Kraton 6S platform, they recognised that the stock 3mm chassis was a potential weak point in vehicles running modern brushless motors with 6S LiPo battery power.

The upgrade to 4mm thickness provides a 33% increase in material, which translates to measurably improved bending resistance and fatigue life. In practical terms, this means your chassis will maintain its geometry better during high-speed runs, resist damage from impacts that might crack or bend a stock chassis, and maintain consistent handling characteristics for longer periods. The CNC machining process ensures that every mounting point is precisely located, every corner radius is consistent, and the overall tolerance stackup is controlled to within tenths of a millimetre. This level of precision is critical when dealing with suspension geometry, as even small variations can affect how your RC car UK model handles and performs on the track or off-road course.

For drivers running the Arrma Kraton 6S with high-performance setups—whether that's competitive racing with premium servo systems and tuned suspension geometry, or aggressive bashing with maximum power delivery—this chassis provides the structural foundation that modern RC drivetrain components demand. The aluminium material also benefits from excellent thermal properties, helping to dissipate heat generated by high-current electrical components, whilst the rigid construction minimises flex that could compromise steering precision or suspension performance.

What's in the Box

• VITAVON CNC Aluminium 7075 Main Chassis 4mm Thickness (choice of silver or red)

What You Need to Complete

Frequently Asked Questions

• Is this chassis compatible with my Arrma Kraton 6S? — This VITAVON chassis is designed specifically for the Arrma Kraton 6S family and is confirmed compatible with models ARA8608V5T1, ARA8608V5T2, and the newer Kraton 6S EXB ARA8708V5. It also fits the Arrma Notorious 6S variants ARA8611V5T1 and ARA8611V5T2. Check your vehicle's model designation to confirm compatibility, though the vast majority of Kraton 6S owners will find this a perfect direct replacement.
• What is the advantage of 4mm thickness over the stock 3mm chassis? — The additional 1mm of aluminium provides a 33% increase in material thickness, which translates to significantly improved structural rigidity, better resistance to bending and twisting under load, and superior fatigue resistance during extended use. This is particularly valuable if you run high-powered brushless setups or bash your vehicle aggressively, as it reduces the risk of chassis damage and maintains more consistent handling characteristics throughout your RC sessions.
• Is this a direct replacement for my stock chassis? — Yes, this chassis is designed as a direct OEM replacement. All mounting points align with the original specification, meaning you can transfer your suspension arms, steering components, electronics tray, and other chassis-dependent parts directly without modification. Installation is simply a case of unbolting your old chassis and bolting on the new one.
• Will this chassis improve my RC buggy's performance? — Whilst this is a structural upgrade rather than a performance upgrade in the traditional sense, it does improve performance by maintaining better handling consistency. The increased rigidity prevents flex-induced geometry changes that can occur with stock chassis under hard driving, meaning your suspension tuning remains more predictable and your steering response more precise. For competitive racers, this translates to faster, more consistent lap times.
• What colours are available? — The VITAVON CNC Aluminium 7075 Main Chassis is available in both silver and red finishes. Both offer identical performance characteristics and are manufactured from the same aerospace-grade aluminium 7075 material.
• Does this chassis require any special maintenance? — Aluminium 7075 is a durable material that requires no special maintenance beyond standard RC vehicle care. Rinse away mud and dirt after outdoor running, allow components to dry properly, and periodically check that fasteners remain tight. The anodised finish on this chassis provides good corrosion resistance in typical UK weather conditions.
