Overview
The ARRMA Rear Suspension Arm Set A for GROM is an essential replacement part for RC enthusiasts who demand durability and consistent performance from their RC vehicles. Whether you're a seasoned basher pushing your GROM to the limit or a dedicated racer looking for reliable spare parts, this suspension arm set delivers the quality and reliability you need to keep your RC car UK-ready for action. ARRMA's reputation for engineering robust RC components is evident in every detail of this suspension upgrade, making it an ideal choice for anyone serious about maintaining their 1/16 scale and 1/18 scale GROM models.
Suspension arms are critical components in any RC vehicle's chassis, responsible for maintaining proper wheel alignment, absorbing impacts from rough terrain, and ensuring smooth, predictable handling characteristics. The rear suspension arms work in tandem with your shocks and chassis to deliver consistent performance whether you're racing on a circuit, bashing through gardens, or tackling technical off-road courses. By choosing genuine ARRMA replacement parts, you're investing in components that have been tested and validated to work seamlessly with your GROM platform.
This complete rear suspension arm set transforms the handling dynamics of your RC car. With precision engineering and tough composite construction, it delivers the crash resistance and durability that modern RC bashers and racers demand. If you're in the UK RC hobby scene and running an ARRMA GROM, having quality spare suspension arms in your workshop is essential maintenance practice.
Key Features
- Tough Composite Material Construction — The suspension arms are manufactured from high-quality composite material that provides exceptional crash resistance and durability during intense driving sessions. This material choice is crucial because it absorbs impacts from obstacles, jumps, and rough terrain without cracking or breaking, ensuring your RC vehicle can handle extreme action without requiring constant repairs.
- Precision Molding for Superior Performance — Each suspension arm is precision-molded to exacting tolerances, ensuring perfect fit and compatibility with your ARRMA GROM chassis. This precision engineering translates directly into smooth suspension operation across all driving conditions, from smooth indoor tracks to bumpy outdoor terrain, maintaining consistent handling characteristics no matter the environment.
- Complete Rear Suspension System — This set includes both upper and lower rear suspension arms, providing a comprehensive solution for rear suspension maintenance or upgrade. Rather than ordering individual components, you get everything needed for complete rear suspension renewal in one package.
- Genuine ARRMA Components — As an official ARRMA product, these suspension arms are engineered to OEM specifications and tested to work flawlessly with your GROM platform. Choosing genuine parts over aftermarket alternatives ensures compatibility and maintains the manufacturer's intended performance characteristics.
- Includes Precision Ball Joints — The set includes precision 4.8 x 4.9 x 2.5mm ball joints that ensure smooth articulation and proper suspension geometry. These ball joints are critical for transferring control inputs smoothly from your radio to the wheels, maintaining responsive handling and predictable cornering behaviour.
Technical Performance
The ARRMA Rear Suspension Arm Set A represents ARRMA's commitment to engineering suspension components that perform reliably across the full range of GROM models in the 1/16 and 1/18 scale categories. The composite material selection is particularly noteworthy, offering the ideal balance between weight and durability — light enough to maintain responsive handling characteristics but tough enough to withstand the impacts and stresses of aggressive RC driving. The precision molding process ensures that each arm maintains consistent dimensions and geometry, which is essential for maintaining proper suspension alignment and delivering predictable handling across all driving speeds and terrains. The included ball joints are manufactured to tight tolerances, ensuring smooth articulation without excessive play that could lead to unpredictable handling or accelerated wear. For UK RC enthusiasts running GROM models including the GORGON GROM, GRANITE GROM, QUAKE GROM, and TYPHON GROM variants, these suspension arms provide the genuine replacement parts needed to maintain peak performance and extend the service life of your investment.

Frequently Asked Questions
- Which ARRMA GROM models are compatible with this rear suspension arm set? — This suspension arm set is compatible with a comprehensive range of ARRMA GROM models, including the GORGON GROM 4X4 RTR Brushed Monster Truck (available in Red, Yellow, and Bronze), GRANITE GROM MEGA 380 Brushed 4X4 Monster Truck RTR (available in Blue/Red, Green, and Red), QUAKE GROM 4X4 RTR Brushed Monster Truck (available in Green, Red, and Purple), and TYPHON GROM variants including the 223S BLX 4X4 and MEGA 380 Brushed 4x4 Buggy RTR models. If you own any GROM-series RC vehicle from ARRMA's current or recent lineup, these arms should be compatible with your model.
- When should I replace my ARRMA GROM suspension arms? — You should consider replacing your suspension arms if you notice visible cracks, splits, or damage to the composite material, if your vehicle's handling becomes unpredictable or unstable during driving, if you notice excessive play or looseness in the suspension geometry, or if you've had a major crash that may have bent or damaged the arms. Regular inspection is recommended, especially if you bash frequently or race competitively.
- Are these suspension arms better than aftermarket alternatives? — As genuine ARRMA components, these suspension arms are engineered to the manufacturer's exact specifications and performance standards. They integrate seamlessly with your GROM's chassis, geometry, and suspension setup. While some aftermarket options may offer different materials or performance characteristics, these genuine arms provide the assurance of proper fit, compatibility, and the performance that ARRMA engineered into your vehicle.
- Do I need to replace all four arms at once? — While this set includes both upper and lower rear arms, you can replace individual arms as needed. However, many experienced RC enthusiasts recommend replacing suspension arms in complete sets to maintain consistent handling and suspension geometry across the entire vehicle. If you've had a major impact or crash, replacing the complete set ensures uniform performance characteristics.
- What tools do I need to install these suspension arms? — Basic RC maintenance tools including hex keys (Allen keys), screwdrivers, and potentially a suspension arm puller may be helpful, depending on whether you're replacing worn arms or installing them new. ARRMA provides detailed instruction manuals with their GROM vehicles that outline the suspension assembly and replacement procedure step by step.
- Is this suitable for beginners? — Suspension arm replacement is an intermediate-level maintenance task that requires some mechanical knowledge and RC-specific tools. Beginners who are new to RC vehicle maintenance might benefit from having an experienced RC enthusiast assist them or having the replacement performed by a local RC hobby shop. However, with patience and the official ARRMA instruction manual, dedicated beginners can successfully perform this maintenance task.
