Overview
The ARRMA Shock Spring Set E delivers precision-engineered suspension tuning for your 1/16 scale GROM RC monster truck. These high-quality shock springs are an essential upgrade and tuning component for any RC enthusiast looking to optimise their vehicle's handling characteristics on the track or during weekend bashing sessions. Whether you're a seasoned RC competitor fine-tuning your setup or a dedicated hobbyist seeking to improve your GROM's performance, this spring set offers the reliability and consistency that ARRMA is recognised for across the UK RC community.
Suspension tuning is one of the most effective ways to customise your RC car's behaviour without major modifications. By swapping shock springs, you can dramatically alter how your vehicle responds to bumps, corners and rough terrain. The ARRMA Shock Spring Set E, rated at 50N/mm (0.55N/mm per spring), provides the stiffness needed to fine-tune your suspension geometry and achieve the exact handling balance your driving style demands. The distinctive bronze colour adds a touch of style to your build whilst maintaining the durability and performance standards expected from genuine ARRMA parts.
This genuine ARRMA component is designed specifically for the 1/16 GROM 4X4 RTR brushed monster trucks, ensuring perfect fitment and compatibility. Ready to run RC vehicles like the GROM benefit greatly from aftermarket suspension upgrades, and this spring set is one of the most effective modifications you can make to unlock your truck's full potential on any terrain.
Key Features
- Precision Manufactured Spring Steel — Each shock spring is crafted from high-quality spring steel using precision manufacturing techniques, ensuring consistent performance across the entire set and long-lasting durability even under demanding racing conditions or aggressive bashing.

- 50N/mm Spring Rate (0.55N/mm per spring) — The specific spring rate of 0.55N/mm (3.14lb/in) provides the ideal stiffness for tuning GROM suspension geometry, offering responsive handling and excellent bump absorption for both track and off-road driving.
- Bronze Colour Finish — Beyond aesthetics, the bronze colour coating helps protect the spring steel from corrosion and wear, whilst adding a premium visual touch to your RC build that complements GROM's aggressive styling.
- Quick and Easy Installation — Installing new shock springs takes only seconds, allowing you to adjust your vehicle's handling characteristics and experiment with different setups without disassembling major chassis components.

Technical Performance
The ARRMA Shock Spring Set E represents a critical suspension component for serious RC enthusiasts. Manufactured from precision spring steel, these springs deliver consistent performance and reliability throughout extended use. The 50N/mm spring rate provides the optimal balance between responsive handling and effective shock absorption, making this set suitable for a wide range of driving conditions encountered by GROM owners across the UK. Whether you're tackling loose gravel tracks, muddy off-road terrain or smooth concrete surfaces, the spring rate is engineered to maintain predictable vehicle behaviour. The bronze colour is not merely decorative; the finish provides additional corrosion resistance, ensuring your investment maintains its appearance and performance over extended periods of use. These springs work in conjunction with GROM's suspension geometry to control ride height, body roll and overall chassis balance. By selecting springs with the correct rate for your driving style and track conditions, you can significantly improve cornering performance, reduce understeer or oversteer, and achieve more consistent lap times. The springs are supplied as a matched set of four, ensuring that front and rear suspension articulation remains balanced and predictable.

Frequently Asked Questions
- What scale GROM models are these springs compatible with? — These springs are specifically designed for the ARRMA 1/16 scale GROM 4X4 RTR brushed monster truck, including both the ARA2130 GORGON GROM and ARA2137 QUAKE GROM variants.
- How do I know if I need new shock springs? — Springs should be replaced when they lose their stiffness over time, when you want to adjust your vehicle's handling characteristics, or if you're upgrading from a standard ready-to-run setup. Many RC enthusiasts carry multiple spring rates to optimise performance for different track conditions.
- What is the difference between spring rates and how do I choose? — Spring rate is measured in N/mm and determines how stiff the spring is. A higher N/mm rating means a stiffer spring that provides less suspension travel and a firmer ride, suitable for bumpy terrain and high-speed driving. A lower rating provides softer suspension, better for smooth tracks and improved traction. The 50N/mm (0.55N/mm per spring) on this set is the standard rate for GROM tuning.
- Can I mix different spring rates on my GROM? — Whilst technically possible, it is not recommended, as mismatched spring rates will cause uneven suspension behaviour and poor handling characteristics. Always use matched sets for balanced performance.
- How long do RC shock springs last? — Quality spring steel springs like these ARRMA components are designed for long-term use and will maintain their stiffness through hundreds of hours of driving. Over time, springs may gradually lose some stiffness due to material fatigue, at which point replacement is recommended for consistent performance.
- Are these genuine ARRMA parts? — Yes, these are official ARRMA parts manufactured to exact OEM specifications. When you purchase from RC Model Shop, you receive genuine components with full compatibility guarantee.
