Overview

The ARRMA Composite Chassis - SWB (Short Wheelbase) is a premium replacement chassis designed specifically for serious RC enthusiasts who demand durability and precision performance. Whether you're a dedicated basher, weekend racer, or experienced RC hobbyist in the UK, this short wheelbase composite chassis delivers the strength and reliability needed to withstand extreme RC action. This is the ideal replacement part for your ARRMA kit, engineered to restore your RC car to factory specifications or upgrade your existing setup with enhanced durability.

Built from tough composite material, this chassis represents ARRMA's commitment to delivering performance-grade components that can handle the demands of high-speed running, technical terrain, and competitive racing conditions. The short wheelbase configuration provides superior manoeuvrability and responsive handling characteristics, making it an excellent choice for drivers who value agility and control. Whether you're running a 1/10 scale monster truck, stadium truck, or other ARRMA platform, this chassis component is engineered to keep you on the track or trail for countless runs.

If your current chassis has sustained damage from aggressive riding, jumps, or racing impacts, the Composite Chassis - SWB is your direct replacement solution. This genuine ARRMA part ensures perfect fitment with integrated lower gearbox housings and suspension mounts, maintaining the exact geometry and performance characteristics your RC vehicle was designed around.

Key Features

• Tough Composite Material Construction — The chassis is manufactured from durable composite material specifically selected for its ability to absorb impacts and maintain structural integrity during extreme RC action, ensuring your vehicle can handle aggressive driving without cracking or breaking.
• Precision Manufactured Mounting Holes — Every mounting hole is manufactured to exacting tolerances, guaranteeing a secure and reliable fit with all associated components, eliminating flex or rocking that could compromise handling or durability.
• Strategic Material Reinforcement in High-Stress Areas — Extra composite material has been deliberately added in critical stress zones where impacts and forces are concentrated, dramatically increasing the chassis's resistance to damage during collisions, jumps, and hard landings.
• Integrated Lower Gearbox Housing — The chassis features an integrated lower gearbox housing that provides structural support for the drivetrain while maintaining clean, compact design that reduces overall vehicle weight and complexity.
• Integrated Lower Suspension Mounts — Suspension mounting points are built directly into the chassis structure, ensuring perfectly aligned geometry and eliminating the need for separate mounting components, which improves reliability and reduces assembly time.
• Short Wheelbase Configuration — The SWB design delivers enhanced turning radius and improved manoeuvrability, allowing you to navigate technical courses with greater precision while maintaining stability during aggressive cornering and high-speed direction changes.

Technical Performance

The Composite Chassis - SWB represents a precision-engineered component manufactured to the highest standards of RC vehicle production. This short wheelbase chassis is designed as a direct replacement part for multiple ARRMA 1/10 scale models, including the GRANITE series (3S, 4X4, and BOOST variants) and the VORTEKS series (3S, 4X4, and BOOST variants). The composite construction provides an optimal balance between weight savings and structural rigidity, critical factors in RC vehicle performance. The integrated lower gearbox housings mean that drivetrain geometry remains perfectly aligned with the original equipment specifications, maintaining the performance envelope your vehicle was designed to deliver. The reinforced stress areas ensure that even in demanding conditions—whether competing on track, racing in off-road environments, or engaging in weekend bashing sessions—the chassis will maintain its integrity and deliver reliable performance run after run. The precision-manufactured mounting holes ensure that assembly is straightforward and that all components sit flush and secure, eliminating any potential for movement that could introduce handling inconsistencies or durability issues. This is an OEM-quality replacement part manufactured to ARRMA's rigorous engineering standards, suitable for both competitive and recreational RC enthusiasts across the UK.

Frequently Asked Questions

• Which ARRMA models is this Composite Chassis - SWB compatible with? — This chassis is a direct fit for multiple ARRMA 1/10 scale vehicles including the GRANITE 3S 4X4 RTR Brushless Monster Truck (ARA4302V3), GRANITE 4X4 RTR Brushed Monster Truck (ARA4202XV3 and ARA4202V3), GRANITE BOOST 2WD RTR Brushed Monster Truck (ARA4102V4 and ARA4102SV4), VORTEKS 3S 4X4 RTR Brushless Stadium Truck (ARA4305V3), and VORTEKS BOOST 2WD RTR Brushed Stadium Truck (ARA4105V4 and ARA4105SV4). It is listed as a standard parts item for these models.
• Is the Composite Chassis - SWB suitable for beginners? — Yes, this is a genuine OEM replacement chassis suitable for all skill levels. Beginners will appreciate its durability and reliable fitment, while experienced bashers and racers will benefit from its reinforced construction and precision engineering. As a replacement part rather than a complete vehicle, basic mechanical knowledge is recommended for installation.
• What makes this short wheelbase design better than a long wheelbase chassis? — The short wheelbase (SWB) configuration delivers superior manoeuvrability and a faster steering response, allowing you to navigate tight corners and technical sections with greater precision. The reduced distance between front and rear axles means the vehicle turns more sharply and requires less steering input, which many drivers prefer for aggressive driving styles and technical terrain.
• Why does this chassis have extra material in high-stress areas? — ARRMA engineers identified the zones where impacts and forces are concentrated during intense RC action—typically around mounting points and suspension areas. By strategically adding extra composite material to these zones, the chassis resists cracking and breaking far better than a chassis with uniform thickness, dramatically extending its lifespan under demanding conditions.
• Can I use this chassis on a damaged vehicle to restore it to factory specifications? — Absolutely. This genuine ARRMA part is designed as a direct replacement for worn or damaged chassis units. The integrated gearbox housings and suspension mounts ensure your vehicle returns to factory geometry and performance specifications, making it an ideal restoration component for any damaged ARRMA platform.
• What is the difference between the SWB and other wheelbase options? — The short wheelbase configuration offered in this chassis provides enhanced manoeuvrability and faster steering response compared to longer wheelbase variants. This makes it ideal for technical courses, tight spaces, and aggressive driving styles where quick directional changes are advantageous.
