Its anodised black finish with laser etching provides that distinctive ARRMA style whilst delivering real-world durability benefits that keep your truck looking sharp through countless bashing sessions.
Key Features
- CNC Machined 7075-T6 Aluminium Construction — This aerospace-grade aluminium alloy is machined to precise specifications, delivering superior strength-to-weight ratio compared to standard steel chassis plates. The 5mm thickness provides exceptional rigidity whilst maintaining the lightweight characteristics essential for optimal RC performance, allowing your motor and battery to deliver maximum acceleration and handling responsiveness.
- Anodised Black Finish with Laser Etching — The anodised coating provides a hard, durable surface that resists corrosion, impacts and the general wear that comes with aggressive RC bashing. The laser-etched ARRMA branding ensures the styling remains crisp and visible long after countless hours of action, giving your truck that professional factory appearance.
- Precision Manufacturing Hardware Mounting Holes — Every fastening point is CNC-produced to exact tolerances, eliminating the frustration of stripped threads or misaligned components. This precision engineering means faster and easier servicing, allowing you to strip down your truck for maintenance or upgrades without wasting time on poor fitment or damaged holes.
- Integrated Droop Setting Plates — Advanced tuning capabilities are engineered directly into the chassis design, allowing you to adjust droop settings in minutes without requiring additional components or tools. This feature enables experienced RC racers and bashers to fine-tune suspension geometry and handling characteristics to match their driving style and track conditions.
- Front Kick-Up Design — The formed kick-up at the front of the chassis helps prevent nose-diving during aggressive acceleration and landing from big air, improving stability and reducing the risk of front-end damage during high-impact manoeuvres typical of 1/5 scale monster truck bashing.
- Angled Sides for Ground Clearance and Stiffness — The strategically angled side sections serve dual purposes: they increase ground clearance to help your truck clear obstacles and rough terrain, whilst simultaneously increasing overall chassis stiffness to provide better handling consistency and more predictable vehicle dynamics across various bashing scenarios.
- Balance of Strength and Handling — This chassis plate is engineered to deliver the perfect equilibrium between raw durability and consistent handling characteristics. The material selection, thickness, and design geometry work together to ensure your ARRMA monster truck maintains predictable, responsive handling whether you're cruising casually or pushing it hard through competitive sessions.
Technical Performance
The ARRMA Chassis represents a masterclass in precision engineering for high-performance RC applications. Manufactured from 5mm thick 7075-T6 aluminium—the same alloy used in aerospace and high-performance engineering applications—this chassis delivers exceptional strength without compromising on weight efficiency. The CNC machining process ensures every aspect of the chassis is produced to exact specifications, with perfectly aligned hardware mounting holes that guarantee reliable fastening and eliminate play or vibration. The anodised black finish isn't merely cosmetic; it's a functional coating that provides genuine corrosion resistance and impact protection, extending the lifespan of your chassis through hundreds of hours of bashing. The integrated droop setting plates allow advanced tuning adjustments that would normally require separate components, making this chassis a feature-rich solution for anyone serious about optimising their 1/5 scale monster truck's performance. The 510mm length positions this chassis in the mid-range of monster truck sizing, providing excellent balance between agility and stability. The front kick-up and angled side design work together to improve ground clearance whilst increasing torsional stiffness, resulting in a chassis that can handle the demands of 8S LiPo power whilst maintaining predictable, responsive handling characteristics even when you're pushing the limits.

Frequently Asked Questions
- What is the ARRMA EXtreme Bash (EXB) specification? — EXB is ARRMA's designation for components engineered from extremely strong and durable materials built to survive the most gruelling action. This means the chassis plate is designed and manufactured specifically to withstand the impacts, stress and demanding conditions of aggressive RC bashing and racing, rather than being a standard component with limited durability expectations.
- Is this chassis compatible with my ARRMA truck? — This 510mm chassis plate is specifically designed for the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck (model C-ARA5808V2T1). Always verify your truck model before purchasing replacement chassis components to ensure perfect compatibility.
- What makes 7075-T6 aluminium special for RC applications? — 7075-T6 is an aerospace-grade aluminium alloy renowned for its exceptional strength-to-weight ratio and fatigue resistance. Unlike softer aluminium alloys, 7075-T6 resists bending and deformation under the repeated stresses of high-performance RC use, whilst remaining lighter than steel alternatives. This makes it the material of choice for precision RC components where performance and durability are equally important.
- Can I adjust the droop settings myself? — Yes, the integrated droop setting plates allow you to make suspension geometry adjustments in minutes without requiring additional parts or special tools. This advanced tuning capability is built directly into the chassis, enabling both experienced racers and committed bashers to fine-tune their truck's handling to match their driving style and local terrain conditions.
- Is this suitable for beginners? — This is a replacement chassis plate rather than a complete ready-to-run RC car, so it's best suited to users who already own an ARRMA Kraton and understand RC maintenance and assembly. If you're new to RC, we'd recommend starting with a complete ready-to-run RC car from RC Model Shop and learning the basics before upgrading individual components.
- Will this chassis work with my existing ARRMA components? — As a precision CNC-manufactured component designed specifically for the ARRMA Kraton 4X4 8S BLX EXB, this chassis is engineered to work seamlessly with all standard ARRMA components and hardware. The precision-manufactured mounting holes ensure perfect alignment and fitment with your existing drivetrain, suspension and electronic components.
