Overview
The ARRMA Shock Springs 70mm 1.5N/mm (8.6lbf/In) are precision-engineered suspension components designed for serious RC enthusiasts who demand professional-grade performance tuning capabilities. These high-quality shock springs are essential for any RC car UK builder or experienced hobbyist looking to fine-tune their vehicle's handling characteristics across different terrain conditions and track surfaces. Whether you're running a 1/7 scale ARRMA desert truck or other compatible brushless RC models, these springs offer the adjustability you need to dial in your suspension setup for optimal performance.
Manufactured by ARRMA, a brand renowned for delivering reliable and competition-grade RC components, these shock springs represent the kind of meticulous engineering that separates casual RC car enthusiasts from those serious about extract maximum performance from their vehicles. The springs enable rapid chassis tuning adjustments, allowing you to adapt your ready to run RC truck or buggy to varying track conditions, weather environments, and driving styles without requiring complete suspension overhauls. This modular approach to suspension tuning is the hallmark of professional RC development and is now available to UK RC enthusiasts at RC Model Shop.
At 70mm in length with a spring rate of 1.5N/mm (8.6lbf/In), these springs provide the precise compliance characteristics needed for responsive handling and consistent performance whether you're bashing in your local park or competing in organised RC events. The set includes two springs, providing enough components for a complete front or rear suspension setup, depending on your vehicle configuration and tuning requirements.
Key Features
- Precision Spring Rate of 1.5N/mm (8.6lbf/In) — This specific spring rate is engineered to provide the ideal balance between suspension compliance and responsive handling, allowing your RC vehicle to absorb impacts whilst maintaining predictable steering feedback and stability during aggressive manoeuvres across varied terrain.
- 70mm Length Design — The 70mm length is specifically engineered to integrate seamlessly with compatible ARRMA shock absorber assemblies, ensuring correct suspension geometry, proper weight transfer characteristics, and optimal ride height for your brushless RC truck or buggy.
- Manufactured from Premium Spring Steel — These shock springs are precision-engineered from high-quality spring steel, which delivers consistent performance characteristics over extended periods of use and maintains its spring rate even after thousands of compression and extension cycles during intense RC driving sessions.
- Rapid Suspension Tuning Capability — By simply changing your shock springs, you can quickly adapt your RC car's suspension characteristics to different track conditions, driving styles, and weather environments without requiring complex mechanical adjustments or complete suspension rebuilds.
- Constant Performance and Longevity — The premium materials and precision manufacturing ensure that these springs deliver reliable, consistent performance throughout their lifespan, providing excellent value for RC enthusiasts and competitors who demand dependable components they can trust.
- Includes Two Springs — This package contains two individual springs, providing enough components to upgrade either the front or rear suspension of your RC vehicle, or to maintain a complete spare set for competition or recreational use.

Frequently Asked Questions
- What ARRMA models are these shock springs compatible with? — These springs are designed to fit ARRMA vehicles including the 1/7 MOJAVE 6S 4X4 RTR Brushless Desert Truck and related ARRMA models with compatible shock absorber assemblies. Always verify your specific model number against the compatibility list before purchasing to ensure perfect fitment.
- How do shock springs affect my RC car's handling? — Shock springs are fundamental to your vehicle's suspension setup, directly influencing how quickly your chassis rises and falls when encountering bumps and terrain variations. A softer spring (lower N/mm rating) allows more suspension travel and smoother ride characteristics, whilst a stiffer spring (higher N/mm rating) provides more responsive handling and quicker weight transfer during aggressive cornering. The 1.5N/mm rating of these springs provides a balanced setup suitable for diverse track conditions.
- When should I replace my shock springs? — Shock springs should be inspected regularly for signs of fatigue, permanent deformation, or loss of spring rate. If your vehicle feels less responsive, sits lower than previously, or doesn't recover quickly from bumps, it may be time to replace your springs. Even without visible damage, springs can gradually lose effectiveness through normal use, making replacement part of regular RC maintenance.
- Can I use these springs with different shock absorbers? — These springs are specifically engineered for ARRMA shock absorber assemblies. Whilst the physical dimensions may appear similar to other brands, using them with incompatible shock absorbers could result in improper suspension geometry, compromised handling, and potential safety issues. Always use springs rated for your specific shock absorber design.
- What is the difference between 1.5N/mm and other spring rates? — Spring rate is measured in force per unit of compression. The 1.5N/mm rate means that each millimetre of compression requires 1.5 Newtons of force. Lower ratings (softer springs) compress more easily but may result in excessive chassis squat; higher ratings (stiffer springs) resist compression but can create a harsher ride. The 1.5N/mm rating of these ARRMA springs represents a well-balanced choice for general-purpose RC driving across varied conditions.
- Do I need to buy these springs in pairs? — These springs are sold as a pair, providing two individual springs. Depending on your suspension setup, you might use both for a complete front or rear suspension upgrade, or maintain one set for spares. Most RC builders keep multiple spring rates on hand to quickly adapt their setup to different driving conditions and track environments.
