Overview
The ARRMA Shock Spring Set B represents an essential upgrade and tuning component for owners of the ARRMA MOJAVE GROM series RC vehicles. Whether you're running the MOJAVE GROM MEGA 380 brushed 4x4 small scale desert truck in RTR configuration or the 1/16 ARRMA MOJAVE GROM 4x4 RTA race kit, having a selection of quality shock springs allows you to dial in your vehicle's handling characteristics with precision and speed. These high-quality shock springs are manufactured to exact specifications and offer the performance tuning capability that serious RC enthusiasts demand from their hobby-grade RC cars and trucks in the UK market.
Shock spring selection is one of the most effective and accessible ways to fine-tune your RC model's suspension behaviour without requiring extensive mechanical knowledge or specialist tools. By adjusting your spring rates, you can instantly modify how your vehicle responds to track conditions, driving style, and terrain challenges. The ARRMA Shock Spring Set B at 0.45N/mm (2.57lb/in) spring rate gives you the flexibility to experiment with suspension geometry and find the sweet spot for your driving preferences, whether you're bashing at weekends, preparing for competitive RC racing, or simply enjoying the thrill of high-speed RC action.
These springs represent genuine ARRMA factory parts, ensuring perfect fitment and compatibility with your existing GROM platform. When you're investing in an RC model truck or any ready to run RC vehicle, access to quality spare parts and tuning components like these shock springs is crucial for long-term enjoyment and performance optimisation. RC Model Shop stocks authentic ARRMA spares so you can upgrade and maintain your RC collection with confidence.
Key Features
- Precision Manufactured Spring Steel — Each shock spring is manufactured from high-quality spring steel using precision engineering techniques, ensuring consistent performance characteristics and long-lasting durability through countless hours of RC driving and racing. This means your suspension will maintain predictable handling behaviour over extended periods of use.
- Set of Four Springs — This package includes four shock springs, providing a complete replacement or upgrade set for all four shock towers on your GROM chassis. Having a full set ensures balanced suspension geometry across the entire vehicle and eliminates any handling inconsistencies that might result from mixed spring rates.
- 0.45N/mm Spring Rate Specification — The 0.45N/mm (2.57lb/in) spring rate represents a specific stiffness rating that defines how resistant the spring is to compression. This rate is designed to work optimally with GROM suspension geometry and provides a versatile middle-ground setup suitable for diverse terrain and driving styles across UK RC tracks and off-road areas.
- Easy Installation and Tuning — Shock spring replacement is one of the quickest and most effective ways to alter your vehicle's suspension behaviour without complex mechanical work. You can experiment with different spring rates to find the perfect setup for your driving style, track conditions, or terrain preferences in minutes rather than hours.
- Genuine ARRMA OEM Parts — These are official factory parts from ARRMA, guaranteeing perfect compatibility with your MOJAVE GROM models and ensuring that you're fitting components designed and tested specifically for your vehicle's suspension requirements.
- Compatible with Multiple GROM Variants — These springs work with the C-ARA2104T1 (MOJAVE GROM MEGA 380 in red), C-ARA2104KT1 (1/16 GROM 4x4 RTA race kit), and C-ARA2104T2 (MOJAVE GROM MEGA 380 in blue), giving you flexibility if you own multiple GROM models or upgrade your platform in future.
Technical Performance
The ARRMA Shock Spring Set B is engineered around the proven MOJAVE GROM chassis platform, which combines brushed motor technology with genuine 4x4 drive capability in a compact 1/16 scale format. The shock springs work as a critical component of the independent double-wishbone suspension system, controlling how rapidly and how far the suspension compresses and extends when the vehicle encounters bumps, jumps, and track obstacles. At 0.45N/mm, these springs strike a balance between providing adequate support for the vehicle's weight whilst remaining responsive enough to track uneven terrain effectively. The precision manufacturing process ensures that all four springs in the set have identical spring characteristics, eliminating any side-to-side handling bias that could result from springs with inconsistent rates. This level of engineering consistency is particularly important in the ready to run RC and race kit segments where predictable handling allows you to develop driving skills and confidence. The spring steel construction provides excellent fatigue resistance, meaning these springs will maintain their performance characteristics through thousands of compression cycles without permanent deformation or loss of stiffness. For UK-based RC enthusiasts looking to maximise performance from their GROM investment, upgrading or replacing stock suspension components with quality aftermarket springs like these represents one of the highest-return modifications available.

Frequently Asked Questions
- What models are these shock springs compatible with? — The ARRMA Shock Spring Set B is designed specifically for the MOJAVE GROM series, including the MOJAVE GROM MEGA 380 brushed 4x4 small scale desert truck in both red and blue variants, and the 1/16 ARRMA MOJAVE GROM 4x4 RTA race kit that comes with battery and charger included. Always verify your specific model code before ordering to ensure compatibility.
- How do I know which spring rate to choose for my RC vehicle? — Spring rate selection depends on your driving style, typical terrain, and vehicle weight. The 0.45N/mm rate in this set represents a versatile middle option suitable for mixed conditions. Softer springs (lower numbers) provide more suspension travel and comfort on rough terrain, while stiffer springs (higher numbers) offer more responsive handling and better control for aggressive driving. Experimenting with different rates is part of the tuning process that makes RC driving so engaging.
- Are these genuine ARRMA parts or aftermarket reproductions? — These are genuine ARRMA factory OEM parts, manufactured to the exact specifications required for perfect fitment and performance on GROM models. Purchasing authentic parts ensures you're getting components designed and tested by ARRMA engineers specifically for your vehicle's suspension geometry and performance requirements.
- Do I need any special tools to install these shock springs? — Shock spring installation typically requires only basic RC tools such as a hex wrench or socket set to remove the existing springs and install the new ones. The actual installation process is straightforward and can be completed in minutes, making this one of the most accessible performance modifications available for RC enthusiasts of any experience level.
- How often should I replace my shock springs? — Quality shock springs like these ARRMA components can last for extended periods under normal use. However, if you notice your suspension feeling softer, your vehicle bottoming out more easily, or inconsistent handling across axles, it may indicate spring fatigue or permanent deformation. Regular inspection during routine maintenance will help you identify when replacement is necessary.
- Can I mix different spring rates on my RC vehicle? — Mixing different spring rates across your vehicle's suspension is possible and sometimes intentional for advanced tuning, but for most users and especially beginners, using a matched set of identical springs like this provides the most predictable and balanced handling characteristics. Once you're experienced with suspension tuning, experimenting with mixed rates can help fine-tune behaviour for specific track conditions.
