Overview
The ARRMA Aluminum Chassis CNC 7075 T6 XLWB Black (Z-ARA320610) is a precision-engineered replacement chassis designed for serious RC enthusiasts who demand superior performance and durability. This high-quality aluminium chassis component is manufactured by ARRMA, a recognised leader in the RC car UK market, and represents the pinnacle of CNC machining technology applied to RC car chassis construction. Whether you are upgrading an existing ARRMA model, repairing damaged chassis components, or building a custom RC vehicle setup, this XLWB (extra-long wheelbase) chassis provides the structural foundation you need for reliable, competitive performance.
Built from premium 7075 T6 grade aluminium alloy and precision CNC machined, this chassis combines lightweight construction with exceptional rigidity and durability. The extended wheelbase design (XLWB) provides improved stability during high-speed runs and cornering, making it an ideal upgrade for drivers who push their RC cars to the limit. This is a component-level part, not a complete ready-to-run RC car, making it perfect for experienced modellers and enthusiasts who are building or customising their own RC vehicles. If you are serious about your RC hobby in the UK and want to ensure your chassis is built from the finest materials available, this ARRMA chassis delivers uncompromising quality.
RC Model Shop stocks this genuine ARRMA part as part of our comprehensive range of RC car spares and tune-ups. Whether you race competitively or bash for fun at the weekend, having access to authentic OEM replacement parts and upgrades ensures your RC vehicle remains in peak condition. This chassis is an essential addition to any serious RC enthusiast's workshop or spares box.
Key Features
- Premium 7075 T6 Aluminium Alloy Construction — The chassis is manufactured from military-grade 7075 T6 aluminium, which is significantly stronger and more rigid than standard aluminium while remaining lightweight, resulting in improved handling characteristics and durability for demanding RC applications.
- Precision CNC Machining — Every component is machined to exact tolerances using computer numerical control, ensuring perfect fitment, consistent quality, and optimal performance across every unit produced.
- Extra-Long Wheelbase (XLWB) Design — The extended wheelbase geometry improves stability during acceleration, braking and high-speed cornering, whilst enhancing traction and reducing chassis flex for more predictable handling.
- Black Anodised Finish — The durable black anodised coating protects the aluminium from corrosion and oxidation whilst providing an attractive professional appearance that complements any RC build.
- ARRMA Genuine OEM Part — This is an authorised ARRMA original equipment manufacturer component, guaranteeing compatibility with ARRMA vehicles and meeting the exact specifications set by the manufacturer.
- Lightweight Performance Benefits — Aluminium chassis construction delivers reduced unsprung weight compared to steel alternatives, improving acceleration, braking response and overall handling characteristics on the track or field.
Technical Performance
The ARRMA Aluminum Chassis CNC 7075 T6 XLWB Black represents cutting-edge engineering in RC chassis design. The 7075 T6 grade aluminium alloy is chosen specifically for its exceptional strength-to-weight ratio, delivering a chassis that weighs significantly less than comparable steel components whilst offering superior rigidity and impact resistance. The CNC precision machining process ensures that every mounting point, bearing pocket and structural feature is manufactured to exacting tolerances, eliminating variances that could compromise performance or fitment. The XLWB (extra-long wheelbase) configuration extends the distance between front and rear axles, distributing the vehicle's mass more effectively and improving stability during dynamic driving. This longer wheelbase geometry reduces the likelihood of the chassis twisting or flexing during acceleration and braking, whilst the rigid aluminium construction absorbs and dissipates impacts without permanent deformation. The black anodised surface treatment provides a protective barrier against moisture, salt spray and UV degradation, ensuring the chassis maintains its structural integrity and appearance through extended use in various weather conditions. Whether you are running this chassis at high speeds on an asphalt track, bashing through muddy terrain, or competing in organised RC events across the UK, the precision engineering and premium materials ensure reliable performance and longevity.

Frequently Asked Questions
- What vehicles is the ARRMA Aluminum Chassis CNC 7075 T6 XLWB Black compatible with? — This is a genuine ARRMA OEM component designed for specific ARRMA RC car models featuring XLWB chassis configuration. Check your vehicle's parts diagram or contact RC Model Shop to confirm compatibility with your specific model before ordering.
- Is this a complete ready-to-run RC car or just a chassis component? — This is a chassis component only, not a complete ready-to-run RC car. It is designed as a replacement part or upgrade component for experienced modellers and builders who are constructing or servicing their own RC vehicles. You will need to transfer or source additional components including motor, ESC, battery, wheels and body to complete a functional RC car.
- What are the advantages of 7075 T6 aluminium for RC chassis? — 7075 T6 is an aerospace-grade aluminium alloy that offers exceptional strength and rigidity whilst remaining lightweight. Compared to standard aluminium or steel, it provides superior resistance to bending and flexing, delivers faster acceleration due to reduced weight, and offers better durability during impacts and high-stress driving conditions.
- How does the XLWB wheelbase improve performance? — The extra-long wheelbase distributes the vehicle's centre of gravity more effectively, improving stability during acceleration and cornering whilst reducing chassis twisting. This geometry is particularly beneficial for high-speed running and provides more predictable handling characteristics compared to standard wheelbase configurations.
- Why choose aluminium chassis over steel? — Aluminium chassis components offer significant weight savings compared to steel whilst maintaining excellent rigidity through precision engineering and quality alloy selection. The reduced weight improves acceleration, reduces power consumption, and enhances overall handling responsiveness, making aluminium the material of choice for serious RC enthusiasts and competitors.
- Does the black anodised finish offer protection? — Yes, the anodised coating provides a protective layer that prevents oxidation and corrosion of the underlying aluminium, extending the chassis lifespan and maintaining its appearance through exposure to moisture, UV light and environmental contaminants.
