Overview

The ARRMA Composite Chassis, 204mm for the Mojave GROM is an essential replacement part designed for serious RC enthusiasts who demand durability and precision in their small-scale desert truck. Whether you're a weekend basher exploring rough terrain or a competitor pushing your RC car UK to the limits, this composite chassis provides the perfect foundation for extreme RC action. The 204mm wheelbase configuration is specifically engineered to deliver the optimal balance between stability and manoeuvrability, making it an ideal upgrade or replacement for your GROM platform. If you've damaged your original chassis during intense off-road sessions or simply want a spare ready to deploy, this professionally manufactured component ensures your ready to run RC truck stays competition-ready.

ARRMA has built a reputation for engineering RC vehicles that withstand the punishment of genuine off-road terrain, and this composite chassis exemplifies that commitment to quality. The Mojave GROM range has become synonymous with affordable, high-performance small-scale RC action in the UK market, and maintaining your vehicle with genuine ARRMA spare parts ensures you're investing in reliability and longevity. This chassis component is manufactured to exacting standards, meaning every mounting point, every structural element, and every integrated feature aligns perfectly with your GROM's other components. When you choose this composite chassis, you're choosing peace of mind and the confidence that comes from using factory-specification parts.

The GROM's compact 1/16 scale makes it perfect for bashing in confined spaces, whilst the 4x4 drive system delivers impressive off-road capability. With brushless or brushed motor options available depending on your GROM variant, this chassis supports both high-performance and budget-conscious builds. From absolute beginners discovering the world of RC vehicles for the first time through to experienced competitors, the GROM platform paired with quality replacement components like this chassis delivers serious fun at an accessible price point.

Key Features

  • Tough Composite Material — The chassis is manufactured from durable composite material specifically selected to withstand the extreme forces generated during aggressive RC action, ensuring your investment remains intact through countless bashing sessions and competitive runs.
  • Precision Manufacturing — Every component is precision manufactured to deliver a secure and reliable fit with all compatible GROM components, eliminating play and ensuring consistent performance during high-speed manoeuvres and technical terrain navigation.
  • Strategic Reinforcement — Extra material has been strategically added in high-stress areas throughout the chassis, significantly increasing durability where impacts and stress concentrations are most likely to occur during aggressive driving.
  • Integrated Lower Gearbox Housing — The chassis features integrated lower gearbox houses that provide robust support for your drivetrain, maintaining alignment and protection for critical transmission components during hard impacts.
  • Integrated Lower Suspension Mounts — Lower suspension mounts are built directly into the chassis structure, ensuring precise geometry and eliminating flex that could compromise handling or suspension performance.
  • 204mm Wheelbase Configuration — The 204mm wheelbase is optimally proportioned for the GROM's compact scale, delivering the perfect balance between stability on high-speed runs and agility in tight technical sections.
  • Factory-Specification Component — As a genuine ARRMA part, this chassis maintains complete compatibility with your GROM platform and integrates seamlessly with all optional upgrades and aftermarket accessories.

Technical Performance

The ARRMA Composite Chassis represents the engineering foundation of the Mojave GROM platform. Composite materials offer an exceptional balance of lightweight construction and impact resistance, critical factors in small-scale off-road RC vehicles where weight distribution directly affects handling characteristics and battery runtime. The 204mm wheelbase configuration has been specifically engineered to provide optimal weight distribution across the front and rear axles, ensuring that whether you're running a brushless 4WD variant with high-performance electronics or a brushed 4x4 configuration, the chassis geometry supports predictable handling and maximum traction delivery. The integrated gearbox housings and suspension mounts eliminate potential weak points, creating a unified structure that absorbs impacts rather than concentrating them at bolt points. This integrated design approach is particularly valuable in small-scale RC vehicles where chassis flex can cause handling inconsistencies and component damage. Whether you're operating your GROM with 3S LiPo batteries on high-speed circuit runs or exploring technical boulder-strewn terrain at moderate speeds, this chassis provides the structural foundation necessary for reliable performance. The strategic reinforcement in high-stress areas means that the chassis maintains its dimensional accuracy even after thousands of impacts, ensuring your suspension geometry and drivetrain alignment remain consistent session after session.

Frequently Asked Questions

  • Is this composite chassis suitable for replacement if I've cracked my original GROM chassis? — Absolutely. This is a genuine factory replacement part manufactured to identical specifications as the original chassis in your GROM. Simply transfer your electronics, suspension components, and drivetrain to this new chassis and you're back to bashing. The precision manufacturing ensures all mounting points align perfectly, meaning installation is straightforward with no modification required.
  • Will this chassis work with both the brushless and brushed GROM variants? — Yes, this chassis is compatible with multiple GROM configurations including the brushless 223S BLX versions and the brushed MEGA 380 versions. The integrated gearbox housings accommodate both motor and ESC configurations, making it a universal replacement across the GROM range.
  • What makes this composite chassis better than an aftermarket alternative? — As a genuine ARRMA factory component, this chassis is engineered specifically for the GROM platform and has been validated through extensive testing by ARRMA's engineering team. The material composition, wall thickness, and reinforcement placement are optimised for the exact drivetrain configuration, weight distribution, and intended use of the GROM, meaning it delivers superior durability and reliability compared to generic composite alternatives.
  • Can I use this chassis to upgrade my existing GROM? — Whilst your existing GROM may function well, upgrading to this composite chassis is beneficial if you're increasing power output, upgrading to more aggressive suspension, or running your GROM in particularly demanding terrain. The strategic reinforcement in high-stress areas provides additional durability margin when pushing your vehicle harder than standard use.
  • How long will this composite chassis last with regular bashing? — Composite materials are inherently durable and maintain their structural properties through countless impacts. With normal care and maintenance, this chassis will last for years of regular use. The strategic reinforcement means that even in high-stress areas, material degradation is minimal, ensuring the chassis remains a reliable foundation for your GROM long-term.
  • Is this suitable for beginners new to RC cars UK? — If you're a beginner with a GROM and you've damaged your original chassis, this replacement component is absolutely suitable. Installation is straightforward as you're simply transferring existing components from your old chassis, and no special tools or advanced mechanical knowledge is required.
