Overview
The ARRMA Shock Spring 84mm M 56.6gf/mm represents a high-quality suspension tuning solution designed for RC enthusiasts who demand precision handling adjustments on their ARRMA vehicles. Whether you're a competitive racer fine-tuning your buggy setup or a weekend basher looking to optimise your RC car's performance, these shock springs offer the flexibility to dial in exactly the suspension characteristics your vehicle needs. As a spare part compatible with ARRMA's range of RC buggies and trucks, these springs are an essential component for any serious RC model shop visitor seeking to improve their machine's handling dynamics without expensive overhauls.
Shock spring selection is one of the most effective tuning methods available to RC car enthusiasts in the UK and beyond. By simply swapping out your existing springs for a different rate, you can fundamentally alter how your vehicle behaves through corners, over jumps, and across varied terrain. The ARRMA Shock Spring 84mm M 56.6gf/mm provides a medium stiffness option that sits perfectly in the middle of the available range, making it an excellent choice for drivers seeking balanced performance across multiple driving conditions. This flexibility in tuning means you can adapt your ready-to-run RC buggy to suit track conditions, driving style, or personal preference in seconds rather than hours.
These high-quality springs are manufactured to exacting standards using premium steel materials, ensuring they maintain consistent performance characteristics throughout their working life. Unlike budget alternatives, genuine ARRMA shock springs retain their rate consistency and don't lose their stiffness prematurely through compression cycles. For RC enthusiasts in the UK looking to get the absolute most from their ARRMA RC vehicle, investing in genuine replacement springs is a cost-effective upgrade that delivers tangible performance improvements.

- Smooth and Reliable Action — The springs are engineered to provide smooth and reliable shock absorber action in all conditions, whether you're racing on tarmac, bashingthrough grass, or tackling muddy off-road terrain, maintaining predictable handling characteristics throughout your driving session.
- Medium Stiffness Rating — At 56.6gf/mm, these springs offer a medium rate that provides balanced performance, absorbing impacts effectively whilst maintaining sufficient support for precise cornering and stable high-speed running.
- Fast Tuning Capability — Changing your shock springs takes mere seconds, allowing you to instantly adjust your vehicle's handling characteristics without dismantling your entire suspension or requiring specialised tools and technical knowledge.

- Wide Range of Options Available — ARRMA offers shock springs in multiple lengths and stiffness rates, allowing RC enthusiasts to select the perfect combination for their specific vehicle and driving style, with softer options like the 52.3gf/mm and stiffer alternatives like the 61.7gf/mm also available.

Technical Performance
The ARRMA Shock Spring 84mm M 56.6gf/mm represents a carefully engineered suspension component manufactured to deliver repeatable, predictable performance in real-world RC driving scenarios. The specification of 56.6 grams-force per millimetre refers to the spring rate—the amount of force required to compress the spring by one millimetre. This medium rating places these springs firmly in the centre of ARRMA's shock spring range, making them suitable for balanced driving that doesn't demand extreme softness for absorption or extreme stiffness for support. The 84mm length is specifically engineered for 1/8 scale ARRMA vehicles, ensuring that the springs integrate seamlessly with your existing suspension geometry and deliver the intended performance characteristics. The premium steel construction means these springs maintain their specified rate consistently throughout their operational life, avoiding the gradual softening that can occur with lower-quality materials. Whether you're adjusting for track conditions that demand softer absorption, or seeking stiffer support for high-speed stability, the availability of multiple spring rates means you can dial in your vehicle's performance with precision. The springs work in conjunction with your shock absorbers to manage weight transfer, maintain consistent ride height, and ensure your tyres maintain optimal contact with the track surface throughout acceleration, braking, and cornering manoeuvres.

Frequently Asked Questions
- What spring rate should I choose for my ARRMA RC car? — The spring rate you select depends on your specific vehicle, driving style, and track or terrain conditions. The M (medium) rate at 56.6gf/mm offers balanced performance suitable for general driving. If you find your car bottoming out or feeling too bouncy, you might try the softer S rate (52.3gf/mm). If your car feels harsh or doesn't absorb impacts well, consider the stiffer H rate (61.7gf/mm). Experimenting with different rates is part of the tuning process that helps you dial in your perfect setup.
- Are these compatible with all ARRMA vehicles? — The 84mm length is compatible with ARRMA 1/8 scale vehicles such as the TYPHON 6S 4WD BLX Buggy. However, ARRMA offers springs in different lengths including 70mm and 76mm options. Always verify your vehicle's shock length before ordering to ensure compatibility. Fitting incorrect length springs will compromise your suspension geometry and handling characteristics.
- How often should I replace my shock springs? — Under normal use, high-quality steel springs like these ARRMA components maintain their rate consistency for extended periods. However, if you notice your vehicle sagging at rest or responding sluggishly to bumps, your springs may have weakened and replacement is recommended. Aggressive racing or bashing may accelerate wear compared to casual driving.
- What is the difference between the S, M, and H spring rates? — ARRMA offers shock springs in three stiffness levels for the 84mm length. The S (Soft) rate measures 52.3gf/mm and provides maximum absorption for rough terrain and big impacts. The M (Medium) rate at 56.6gf/mm balances absorption and support for general purpose driving. The H (Hard) rate at 61.7gf/mm provides maximum support and stiffness for high-speed running and precise cornering. Choose based on your driving conditions and preference for how your vehicle handles bumps and weight transfer.
- Do I need any special tools to change my shock springs? — Shock springs can typically be changed with basic tools like hex keys and screwdrivers. The process usually involves removing your shock bodies, uncompressing the springs with a spring compressor or by hand, removing the old springs, and installing the new ones. Refer to your vehicle's manual for specific installation instructions. This is one of the easiest tuning modifications you can perform on your RC car.
- Can I mix and match different spring rates on my vehicle? — Some advanced drivers do experiment with different front and rear spring rates to fine-tune their vehicle's behaviour. However, for most users, matching rates front and rear provides predictable, balanced handling. If you're new to spring tuning, start with matching rates and only experiment with mixed rates once you understand how spring rate affects your vehicle's performance.
