Overview
The ARRMA Aluminum Chassis CNC 7075 T6 SWB Black is a premium upgrade chassis designed for serious RC enthusiasts looking to enhance their high-performance 1/8 scale brushless RC vehicles. This precision-engineered component represents the pinnacle of chassis technology, offering the kind of durability and performance tuning capabilities that competitive RC car UK drivers demand. Whether you're upgrading an existing Outcast, Notorious, or Typhon 6S model, or building a custom ready to run RC setup, this CNC machined aluminium chassis delivers the strength and handling consistency needed for both track racing and aggressive bashing.
Built from aerospace-grade 7075-T6 aluminium, this short wheelbase (SWB) chassis is manufactured using computer numerical control (CNC) machining to ensure tolerances so precise that every mounting hole aligns perfectly with your vehicle's components. The black anodised finish combined with laser etching creates a chassis that not only performs at the highest level but also looks distinctly ARRMA with professional styling. This is the kind of upgrade that transforms how your brushless RC truck or buggy handles, providing the perfect balance between raw strength and responsive performance characteristics.
RC car enthusiasts across the UK have come to trust ARRMA components for their reliability and performance. This chassis plate is designed to withstand the extreme stresses of high-speed running, competitive racing, and serious bashing sessions. The engineering focuses on providing durability without compromising the handling precision that makes your vehicle feel planted and predictable, whether you're carving corners on a track or launching over jumps off-road.
Key Features
- CNC Machined from 7075-T6 Aluminium — The chassis is precision-manufactured from aerospace-grade 7075-T6 aluminium, one of the strongest aluminium alloys available in the RC industry. This material delivers ultimate strength and rigidity, meaning your chassis maintains its shape and geometry even under extreme driving conditions and impacts that would damage lesser materials.
- Anodised Black Finish with Laser Etching — The chassis receives a premium anodised black coating that provides significantly increased durability against corrosion, scratches, and weathering. The laser etching adds authentic ARRMA branding and styling that stands out visually, while the anodised layer protects the bare metal underneath from oxidation and wear.
- Precision Manufactured Hardware Mounting Holes — Every mounting hole is engineered with exacting tolerances during the CNC manufacturing process, ensuring fast and easy servicing when you need to access components, adjust suspension, or perform maintenance on your RC vehicle. No stripped holes or misaligned fasteners—everything fits perfectly every time.
- Integrated Droop Setting Plates — Built directly into the chassis design are advanced tuning plates that allow you to adjust droop settings in minutes without requiring complex modifications or additional parts. This feature enables precise suspension tuning that directly impacts how your RC buggy or truck behaves on different surfaces and at different speeds.
- Front Kick-Up Formed Into Chassis — The chassis incorporates a front kick-up that is formed directly into the structure, preventing nose-diving during acceleration and improving overall handling balance during hard acceleration events. This subtle but important design feature helps maintain traction and prevents your vehicle from becoming unstable during aggressive driving.
- Angled Sides for Ground Clearance and Stiffness — The sides of the chassis are angled to provide increased ground clearance, preventing the chassis from high-centering on obstacles and allowing your RC truck or buggy to navigate rougher terrain more effectively. Simultaneously, these angled sides provide added structural stiffness to the overall chassis platform, reducing flex and improving handling response.
- Perfect Balance of Strength and Handling — This chassis is designed specifically to deliver the optimal balance between raw durability and responsive handling characteristics. Unlike chassis plates that prioritise only strength or only agility, this ARRMA component ensures your vehicle remains predictable and satisfying to drive while maintaining the toughness needed for serious RC action.
Technical Performance
The ARRMA Aluminum Chassis CNC 7075 T6 SWB represents cutting-edge manufacturing in the RC industry. The 7075-T6 aluminium alloy used in construction is the same material trusted in aerospace applications, delivering a strength-to-weight ratio that is exceptional within the RC car UK market. The CNC machining process creates a chassis with tolerances measured in fractions of millimetres, ensuring that when you install this component into your 1/8 scale brushless RC vehicle, everything aligns perfectly without adjustment or modification. The black anodised finish is not merely cosmetic—it is a protective coating that prevents galvanic corrosion and extends the service life of the component significantly. The integrated droop plates allow for suspension geometry adjustments that were previously only possible by purchasing multiple chassis options, giving you unprecedented tuning flexibility within a single component. The front kick-up geometry is engineered to work in harmony with the angled sides, creating a chassis that maintains a low centre of gravity while simultaneously offering excellent approach and departure angles for aggressive terrain navigation. Whether you are running your RC buggy or truck on a competitive racing track where precision handling is paramount, or bashng through rough outdoor terrain where durability is tested to the limit, this chassis delivers performance across all driving conditions.

Frequently Asked Questions
- Which ARRMA models is this chassis compatible with? — This SWB (short wheelbase) chassis is designed as a standard part for several 1/8 scale ARRMA models including the Notorious 6S 4WD brushless stunt truck, Outcast 6S 4WD brushless stunt truck, and Typhon 6S 4WD brushless buggy. It is compatible with multiple versions of these models including the EXB variants and TLR tuned versions. Always verify your specific model number against the compatibility list before ordering.
- What makes 7075-T6 aluminium better than standard aluminium? — 7075-T6 is an aerospace-grade aluminium alloy that is significantly stronger and more durable than standard 6061 aluminium commonly used in some RC chassis plates. The T6 designation refers to the heat-treatment process that maximises strength and hardness. This means your chassis will resist bending, warping, and cracking far better than lower-grade alternatives, translating to longer component life and more consistent handling over extended use.
- Can this chassis be upgraded into my existing ARRMA truck or buggy? — Yes, this chassis is designed as an upgrade component that can be installed into compatible ARRMA 1/8 scale models. Because it is a standard part rather than a custom modification, installation is straightforward for anyone with basic RC knowledge. The precision manufacturing ensures all mounting holes align correctly with existing components, meaning no modification to other parts of your vehicle is required.
- What is the difference between SWB and LWB chassis options? — SWB stands for short wheelbase, whilst LWB stands for long wheelbase. The wheelbase is the distance between the front and rear axles. A short wheelbase chassis like this one provides quicker turning response and more aggressive handling characteristics, making it ideal for tight courses and competitive racing. A long wheelbase chassis would provide more stability and higher-speed straight-line performance. Your choice depends on your intended driving style and the terrain or track you will be using.
- How does the integrated droop adjustment feature work? — Droop refers to how far the suspension can extend downward when the wheels are unloaded. The integrated droop setting plates built into this chassis allow you to adjust this parameter by simply changing which mounting holes you use, without requiring you to purchase additional chassis options or make complex modifications. This level of tuning flexibility was previously only available to competitive racers with multiple chassis options.
- Is the anodised finish just for looks? — Whilst the anodised black finish certainly looks professional and distinctly ARRMA, the anodising process serves critical protective functions. The anodised coating prevents oxidation of the bare aluminium underneath, protecting against corrosion from moisture, dirt, and the various liquids encountered during RC driving. This extends the service life of your chassis and maintains its performance characteristics over time.
