Key Features
- CNC Machined from 7075-T6 Aluminium — This high-grade aluminium alloy is specifically selected for RC applications because it offers exceptional strength-to-weight ratio, meaning your chassis remains incredibly rigid and strong whilst keeping overall vehicle weight to a minimum, which directly translates to faster acceleration and better handling response.
- Anodised Black with Laser Etching — The black anodised finish provides a hard, protective layer that resists corrosion, scratches, and UV damage from outdoor use, whilst the laser etching adds authentic ARRMA branding and style that looks professional and aggressive on your RC monster truck.
- Precision Manufactured Hardware Mounting Holes — Every mounting hole is engineered to exact specifications, ensuring fasteners fit perfectly first time without stripping or wobbling, which means faster and easier servicing when you need to access components, replace parts, or perform maintenance on your brushless RC truck.
- Integrated Droop Setting Plates — These built-in adjustment features allow you to fine-tune your chassis droop settings in minutes without special tools or complex modifications, giving you advanced tuning options that competitive RC racers use to dial in perfect suspension geometry for different track conditions and driving styles.
- Front Kick-Up Design — The formed front kick-up reduces the risk of nose-diving during aggressive acceleration and helps maintain optimal weight distribution, which improves stability when launching from a standstill and prevents front-end damage when landing jumps.
- Angled Sides for Ground Clearance — The strategically angled side profile increases ground clearance, preventing the chassis from grounding out on obstacles, whilst simultaneously adding structural stiffness to the overall chassis design for improved rigidity and handling precision.
Technical Performance
The ARRMA Aluminum Chassis CNC 7075 T6 LWB represents the pinnacle of modern RC chassis engineering, specifically designed for the demanding world of 1/8 scale high-performance speed trucks. The 7075-T6 aluminium material is significantly stronger than standard aluminium alternatives, offering superior impact resistance and durability during aggressive bashing sessions or competitive racing. The long wheelbase (LWB) configuration provides enhanced stability at high speeds whilst maintaining manoeuvrability through corners. Every aspect of this chassis has been engineered for the 1/8 KRATON 6S platform, which is known for its brushless motor performance and 4WD capabilities. The CNC machining process ensures tolerances are held to exacting standards, meaning mounting holes align perfectly with suspension components and electronic systems. The integrated droop setting plates eliminate the need for additional shims or complicated adjustments, allowing you to modify suspension geometry quickly between runs. This chassis is specifically compatible with KRATON 6S models including the EXB variant, V5, V6, and EXB AVC versions, making it a versatile upgrade or replacement option. The angled sides not only improve ground clearance over obstacles but also contribute to chassis stiffness by increasing the effective wall thickness in critical areas. Whether you're running this on a standard ready to run RC setup or a fully tuned competition machine, the engineering and material quality ensure consistent performance and longevity. The black anodised finish means this chassis resists corrosion from moisture and salt, important for UK RC enthusiasts who may use their vehicles in various weather conditions.

Frequently Asked Questions
- Is the ARRMA Aluminum Chassis CNC 7075 T6 compatible with my KRATON 6S RC truck? — Yes, this chassis is designed as a standard part for multiple 1/8 KRATON 6S models, including the EXB, V5, V6, and EXB AVC variants. Check your specific model number against the compatibility list to confirm fitment before ordering.
- What makes 7075-T6 aluminium better than standard aluminium for RC chassis? — 7075-T6 is a high-strength aluminium alloy that offers significantly better impact resistance, durability, and rigidity compared to standard grades. This means your chassis can handle harder crashes, aggressive driving, and high-speed impacts whilst maintaining structural integrity, making it ideal for serious RC enthusiasts who don't want frequent replacements.
- Can I use this chassis as an upgrade, or is it just a replacement part? — This is primarily a replacement chassis plate compatible with 1/8 KRATON 6S models, though upgrading to this premium CNC-machined version from an older or inferior chassis would provide improved handling and durability. It functions as both a replacement and upgrade depending on what your current setup uses.
- How does the integrated droop setting feature help with my RC car UK performance? — Droop adjustments control how much the suspension hangs down when the vehicle is sitting still, which affects how the suspension responds to bumps, jumps, and cornering forces. The integrated plates let you change these settings quickly without removing the chassis, allowing you to experiment with different setups for various track conditions and driving styles without major disassembly.
- Is the black anodised finish durable? — Yes, anodising creates a hard, protective oxide layer that resists corrosion, scratches, and UV damage. This finish is particularly beneficial for UK users who may subject their RC vehicles to wet conditions, salt spray, or intense sunlight. The laser etching adds authentic styling whilst remaining protected under the anodised layer.
- What tools do I need to install this chassis? — This depends on your specific KRATON 6S configuration, but the precision-manufactured mounting holes mean standard RC tools and fasteners will fit perfectly. Refer to your vehicle's manual for specific installation instructions, though the straightforward design typically requires only basic RC screwdrivers and hex keys.
