ARRMA Composite Chassis 200mm – GROM (ARA320809) | Durable RC Replacement Part

Meet the ARRMA Composite Chassis (200mm) designed as a robust replacement part for your GROM kit. Built from a tough composite material, this chassis is shaped to withstand the bumps and twists of intense RC action while preserving the original balance of your model. The 200mm wheelbase mirrors the layout of ARRMA's GROM configurations, helping maintain confident steering and predictable handling as you push speed and grip on varied terrain.

Why this chassis stands out

Precision manufacturing ensures a snug, secure fit with minimal setup fuss. Extra material is strategically added in high-stress areas to boost durability where contact, impact, and flex loads are most common. The integrated lower gearbox housings and lower suspension mounts simplify assembly and alignments, reducing guesswork during maintenance and rebuilds.

• Tough composite material provides long-lasting durability during extreme RC action
• Precision manufactured for a secure, reliable fit with your kit
• Extra material in high-stress zones to improve durability and fatigue resistance
• Integrated lower gearbox housings and lower suspension mounts for easier installation

What you get is a direct replacement that respects the geometry and handling of the original model. This component preserves the intended ride height, weight distribution, and chassis rigidity, so you can focus on tuning and drive direction rather than part-fit concerns.

Real-world use cases and benefits to consider

On muddy off-road tracks, rocky trails, or fast laps on a synthetic surface, a sturdy chassis helps you maintain form and control through corners and landings. While performance varies with setup and driving style, the durable design reduces the risk of chassis flex and deformation during hard landings or impact events.

• Replace worn or damaged chassis to restore original feel and geometry
• Upgrade for increased resilience on rough terrain

Designed specifically for ARRMA GROM models (ARA320809), the chassis aligns with the brand’s design language and component interfaces. For best results, pair with appropriate maintenance and inspection routines, and store or transport the kit to minimize stress on the chassis material.
