Key Features
- CNC Machined 7075-T6 Aluminium Construction — The 5mm thick aluminium chassis plate is CNC machined from premium 7075-T6 material, which is recognised across the RC industry as one of the strongest and most durable alloys available, ensuring your vehicle can survive intense bashing and competitive use without cracking or bending under stress.
- Anodized Black Finish with Laser Etching — The chassis plate features an anodized black coating combined with laser etching, which not only gives it authentic ARRMA style and visual appeal but significantly increases durability and resistance to wear, corrosion and impact damage during aggressive driving sessions.
- Precision Manufactured Hardware Mounting Holes — Every mounting hole is precisely manufactured to exacting tolerances, allowing for fast and easy servicing of your RC vehicle without the frustration of stripped threads or misaligned components, saving you time and money on repairs.
- Integrated Droop Setting Plates — The chassis includes integrated droop setting plates that give you advanced tuning options in minutes, allowing you to dial in the perfect suspension geometry for your specific driving conditions and personal preferences without needing additional tools or components.
- Front Kick-Up Design — A front kick-up is formed into the chassis structure, which helps prevent nose-diving during aggressive acceleration and improves ground clearance when tackling obstacles, enhancing both performance and durability in challenging terrain.
- Angled Sides for Enhanced Performance — The angled sides of the chassis provide dual benefits: they increase ground clearance for better obstacle clearing and add structural stiffness throughout the chassis, which translates to improved handling characteristics and reduced flex during hard cornering.
Technical Performance
This EXtreme Bash (EXB) specification chassis plate is engineered using professional-grade materials and manufacturing processes to meet the demands of serious RC enthusiasts throughout the UK and beyond. The 5mm thickness of the 7075-T6 aluminium provides exceptional strength-to-weight ratio, allowing the chassis to absorb impacts and stress without unnecessary weight gain that would compromise acceleration and handling. The CNC machining process ensures dimensional accuracy across every component, which is critical for maintaining consistent performance and easy servicing. The integrated droop setting plates allow drivers to fine-tune suspension geometry on the fly, whether you need more aggressive downforce for high-speed cornering or a softer setup for technical terrain. At 445mm in length, this chassis is specifically designed for ARRMA's 1/5 scale platform, and the angled side walls work in conjunction with the front kick-up to provide superior ground clearance compared to conventional flat designs. The anodized finish provides genuine durability protection against the elements, making this chassis suitable for various weather conditions across the UK without fear of corrosion. The laser-etched ARRMA branding ensures the professional aesthetic remains visible even after extensive use and cleaning.

Frequently Asked Questions
- Which ARRMA vehicle is this chassis plate compatible with? — This Z-ARA320614 chassis plate is compatible with the ARRMA 1/5 Outcast 4x4 8S BLX EXB Brushless Stunt Truck RTR. It is a direct replacement part designed specifically for this model, ensuring perfect fit and optimal performance.
- What makes 7075-T6 aluminium better than standard materials? — 7075-T6 is an aerospace-grade aluminium alloy that offers superior strength and durability compared to standard aluminium or plastic alternatives. It resists bending and cracking under extreme stress, making it ideal for high-performance RC applications where durability is essential.
- Can I use this for both competitive racing and casual bashing? — Absolutely. This EXtreme Bash (EXB) specification component is engineered for both demanding competitive use and intense recreational bashing. The integrated tuning options and robust construction make it versatile enough to handle whatever driving style you prefer.
- How does the anodized finish help durability? — The anodized black coating creates a protective layer on the aluminium surface that resists corrosion, UV damage, and oxidation. This is particularly important in the UK where weather can be unpredictable, as it prevents rust and maintains the structural integrity of the chassis over extended use.
- What advantage do the integrated droop setting plates provide? — The integrated droop plates allow you to adjust suspension geometry quickly without removing the entire chassis or purchasing separate tuning components. This means you can optimise your vehicle's handling in minutes rather than hours, and experiment with different setups to find what works best for your driving conditions.
- Will this improve my vehicle's ground clearance? — Yes. The angled sides and front kick-up design increase ground clearance compared to flat chassis designs, helping prevent hang-ups on obstacles and allowing you to tackle more challenging terrain without damage to the chassis.
