Whether you're an experienced RC enthusiast looking to maintain your investment or a dedicated basher pushing your vehicle to its limits, this composite chassis delivers the performance and longevity expected from ARRMA's engineering excellence.
Composite chassis designs have become the gold standard in RC car UK culture, and this V2 iteration represents ARRMA's commitment to continuous improvement. The medium wheelbase configuration strikes the perfect balance between stability and manoeuvrability, making it suitable for a wide range of driving styles and terrain conditions. If you've suffered chassis damage during aggressive driving or simply want to upgrade your existing setup with the latest V2 technology, this single-piece composite chassis is engineered to withstand the demands of modern RC stunt truck performance.
This is not just a replacement part—it's an investment in the longevity and performance of your ARRMA 4S vehicle. The composite material used throughout the construction has been specifically formulated to resist the impacts, stresses and strains that come with serious RC action, whether that's high-speed bashing, freestyle tricks or competitive racing on UK circuits.
Key Features
- Tough Composite Material — The chassis is manufactured from a durable composite material that provides excellent impact resistance and longevity during extreme RC action. This material choice means your chassis will withstand repeated impacts, jumps and hard landings far better than traditional plastic alternatives, keeping your RC car UK-ready for season after season.
- Precision Manufacturing — Every chassis is precision manufactured to exacting tolerances, ensuring a secure and reliable fit with all compatible components. This attention to detail during production means you won't experience loose connections or fitment issues that could compromise performance or cause unexpected failures during operation.
- Strategically Reinforced High-Stress Areas — Extra material has been intelligently added to areas of the chassis that experience the greatest stresses during driving, such as suspension mounting points and drive train connections. This targeted reinforcement approach extends the service life of the chassis without adding unnecessary weight to the entire assembly.
- Integrated Lower Gearbox Houses — The chassis features integrated lower gearbox houses that provide precise mounting for your transmission components. This integrated design ensures proper gear alignment and reduces flex during aggressive acceleration and cornering, translating to more consistent handling and better durability.
- Lower Suspension Mounts — Integrated lower suspension mounts mean your shocks and suspension geometry are secured to the most rigid part of the chassis possible. This rigid connection improves suspension response and handling consistency, giving you better control over your RC stunt truck during dynamic driving situations.
- Centre Diff Module Compatible — This chassis is engineered to work seamlessly with centre differential modules, allowing you to upgrade your drivetrain setup as your driving needs evolve. The centre diff compatibility opens up a range of performance tuning options for enthusiasts looking to optimise their vehicle handling.
- Slipper Clutch Module Compatible — The chassis accepts slipper clutch modules, giving you the ability to protect your drivetrain during acceleration spikes and sudden impacts. This compatibility means you can configure your vehicle exactly how you want it for your particular driving style and conditions.
Technical Performance
The ARRMA Composite Chassis: MWB V2 represents a complete rethinking of how composite chassis should be engineered for modern RC stunt trucks. The medium wheelbase configuration provides the optimal balance between wheelbase length and overall vehicle dynamics that professional and recreational RC enthusiasts demand. The use of composite materials throughout the construction delivers a chassis that is both lightweight and exceptionally strong, crucial characteristics for any serious RC vehicle. The integrated gearbox houses and suspension mounts are manufactured as a single unified piece, eliminating the flexibility and potential failure points that come with multi-piece chassis designs. The precision manufacturing standards ensure that when you fit this chassis to your ARRMA 1/10 OUTCAST 4X4 4S V2 BLX Stunt Truck, everything aligns perfectly with no gaps, warping or fitment issues. The strategic reinforcement of high-stress areas means that impact zones, suspension mounting points and drivetrain connection areas are built to withstand repeated extreme stresses. This is a chassis designed not just for casual weekend driving but for the serious demands of competitive RC car UK environments where reliability directly impacts performance.
