Overview
The ARRMA Spring Tuning Set (2): MINI is an essential suspension upgrade for owners of the ARRMA MINI KRATON 3S who want to fine-tune their RC car's handling characteristics. These precision-engineered shock springs allow you to adjust your vehicle's performance in seconds, making them perfect for both casual weekend bashers and serious RC enthusiasts looking to optimise their setup. Whether you're exploring different terrain types or simply want to dial in the perfect ride height and suspension response, this tuning set gives you professional-level control over your 1/16 scale brushless RC monster truck without requiring complex modifications.
Spring tuning is one of the most effective ways to improve an RC car's handling on the track or trail. Stiffer springs increase ground clearance and reduce body roll during cornering, while softer springs provide better traction and a smoother ride over bumpy terrain. By having alternative springs on hand, you can quickly experiment and find the exact setup that suits your driving style and local conditions. The ARRMA Spring Tuning Set (2): MINI makes this process straightforward and accessible to all skill levels, from newcomers to the RC car UK hobby through to experienced racers fine-tuning their competition vehicles.
ARRMA has long been recognised as a leader in producing durable, high-performance RC models, and these shock springs reflect that commitment to quality. Manufactured to exacting tolerances, each spring maintains consistent performance characteristics throughout its lifespan, ensuring reliable handling behaviour whether you're running on tarmac, grass, or loose terrain. For anyone serious about maximising their ready to run RC experience, this tuning set is an affordable and practical addition to any toolbox.
Key Features
- Precision manufactured spring steel — Each spring is crafted from high-quality spring steel to ensure consistent performance and exceptional durability. This precision manufacturing means springs maintain their rate and tension reliably over extended use, preventing unpredictable handling changes and guaranteeing that your tuning efforts deliver repeatable results every time you take your brushless RC mini monster truck out.
- Marked for easy identification — Every spring in this set is clearly marked, making it simple to identify which springs are installed and swap them out for different spring rates without confusion. This labelling system saves valuable time when you're experimenting with setups at the track or field, allowing you to quickly reference your notes and recreate winning configurations.
- Two different spring rates included — The set provides both front and rear springs with different stiffness ratings, giving you the flexibility to adjust handling balance. The included springs allow you to experiment with various suspension characteristics and dial in the perfect balance for your specific driving style and terrain.
- Quick and easy installation — Spring tuning requires no special tools or technical knowledge beyond basic RC car maintenance. You can change springs in seconds, making it practical to test multiple setups during a single session and find the configuration that works best for you.
Technical Performance
This spring tuning set is engineered specifically for the 1/16 MINI KRATON 3S DSC 4WD RTR brushless speed monster truck, ensuring perfect fitment and optimal performance. The set includes two rear shock springs rated at 0.70N/mm with a 45mm length, and two front shock springs rated at 1.28N/mm with a 32mm length. These spring rates provide a solid foundation for handling adjustment, with the stiffer front springs offering more support during acceleration and cornering, whilst the softer rear springs allow the rear suspension to absorb terrain imperfections and maintain traction. The material specification of precision spring steel ensures that the springs maintain their characteristics over thousands of compression cycles, whether you're running aggressive high-speed terrain bashing sessions or technical obstacle courses. For UK-based RC enthusiasts running brushless RC 1/16 scale vehicles, having multiple spring options is essential for adapting to changing weather conditions and different track layouts. Spring tuning is one of the most cost-effective ways to improve handling without upgrading expensive components, making this set an exceptional value addition to your ARRMA MINI KRATON setup.

Frequently Asked Questions
- Will these springs fit my ARRMA MINI KRATON? — Yes, this spring tuning set is designed specifically for the ARRMA MINI KRATON 3S and MINI KRATON 3S DSC models, ensuring perfect compatibility and fitment to your shock absorbers.
- What do the spring rate numbers mean? — The N/mm rating indicates the spring rate or stiffness. The rear springs at 0.70N/mm are softer, whilst the front springs at 1.28N/mm are stiffer. Stiffer springs reduce body roll and increase ground clearance, whilst softer springs improve traction and provide a smoother ride over rough terrain.
- How often should I change my springs? — Springs don't wear out like moving parts, but you might change them to suit different conditions. Experiment with different setups to find what works best for your driving style and the surfaces you're running on most frequently.
- Do I need special tools to install these springs? — Spring installation on most RC shock absorbers requires only basic tools you likely already have. The marked springs make identification straightforward, and installation takes just seconds per spring.
- Are these springs suitable for beginners? — Absolutely. Spring tuning is one of the safest and easiest ways for beginner RC enthusiasts to learn about suspension setup and vehicle handling. There's no risk of damaging electronics or the chassis, and the learning curve is very manageable.
- What's the difference between front and rear spring rates? — Front and rear springs are rated differently because they serve different purposes in the suspension. Front springs handle steering and cornering forces, whilst rear springs manage acceleration traction and jump landing impact. The included springs are matched to provide balanced handling for the MINI KRATON.
