Overview
These ARRMA Shock Springs are precision-engineered replacement suspension components designed to transform your RC car's handling characteristics in seconds. Whether you're piloting an ARRMA 1/10 Kraton 4S or Outcast 4S, these high-quality shock springs provide the tuning flexibility that serious RC enthusiasts demand. As an essential part of your RC model suspension system, these springs allow you to fine-tune your vehicle's ride height, cornering stability and overall on-track performance without needing specialist tools or complex adjustments. If you're looking for quality suspension spares for your brushless RC truck in the UK, these genuine ARRMA springs deliver the consistency and durability that you'd expect from an authorised manufacturer component.
Suspension tuning is one of the most effective ways to optimise your RC car's performance across different track conditions and driving styles. By selecting the correct spring rate, you can soften your ride for rough terrain or stiffen it for competitive racing surfaces. The ARRMA Shock Springs: 95mm 1.00N/mm (5.71lb/in) offer a medium spring rate that makes them versatile across a range of driving scenarios, from casual bashing to more serious track use. These springs are compatible with both the Kraton and Outcast 4S models, making them a must-have spare for owners of these popular ready-to-run RC trucks.
Built from precision-manufactured spring steel, these shock springs are engineered to deliver consistent performance session after session, with the durability to withstand the demands of regular use. Rather than settling for worn-out original springs that lose their rate over time, upgrading to fresh ARRMA springs ensures your vehicle maintains its intended handling balance and responsiveness. The fact that they're supplied as a pair means you have a complete spring set for either the front or rear suspension, or you can purchase multiple pairs to build a complete suspension refresh.
Key Features
- Precision-manufactured spring steel construction — These shock springs are crafted from high-quality spring steel that has been precision-engineered to maintain consistent spring rates and performance characteristics throughout their lifespan, ensuring your RC truck handles predictably lap after lap.
- Supplied as a pair — You receive two shock springs in this package, providing a complete spring set for either front or rear suspension, or allowing you to experiment with different spring rate combinations for advanced tuning.
- 95mm length — The 95mm overall length is specifically designed to fit ARRMA 1/10 scale models including the Kraton 4S and Outcast 4S, ensuring perfect compatibility without modification or fitment issues.
- 1.00N/mm spring rate (5.71lb/in) — This medium spring rate provides a balanced platform for various driving conditions, offering enough compliance for off-road terrain whilst maintaining the stiffness needed for controlled cornering and jump landings.
- Quick suspension tuning — By simply swapping out your existing shock springs for a different rate, you can transform your vehicle's handling characteristics without disassembling the rest of your suspension, making this one of the quickest performance adjustments available to RC enthusiasts.
- Genuine ARRMA component — These are original manufacturer parts, not third-party alternatives, guaranteeing fitment quality and performance consistency that matches your vehicle's engineering specifications.
Technical Performance
The ARRMA Shock Springs: 95mm 1.00N/mm represent precision suspension engineering at the heart of your RC truck's performance envelope. The 1.00N/mm spring rate (equivalent to 5.71lb/in in imperial measurement) sits in the middle of the suspension tuning range, making these springs suitable for drivers seeking a balanced approach to both recreational bashing and competitive driving. The 95mm length is specifically matched to the suspension architecture of ARRMA's 1/10 scale brushless 4WD trucks, ensuring proper ride height and maintaining the geometric integrity of your suspension geometry. The precision-manufactured spring steel used in these components has been engineered to resist fatigue over thousands of compression and extension cycles, meaning your shock springs will maintain their rate stability even after extended use. Spring rate selection is fundamental to RC vehicle tuning; softer springs (lower N/mm ratings) provide greater suspension travel and compliance over rough terrain, whilst stiffer springs (higher N/mm ratings) reduce body roll and improve responsiveness on smooth or competitive surfaces. By offering these springs in a standard 1.00N/mm rate, ARRMA provides an accessible entry point for tuning, with harder and softer alternatives available as separate part numbers for those looking to dial in their suspension further. When you upgrade to fresh shock springs, you're restoring your vehicle to its original handling characteristics and removing the performance degradation caused by worn, permanently deformed springs that have lost their original rate.

Frequently Asked Questions
- What RC models are these ARRMA shock springs compatible with? — These 95mm 1.00N/mm springs are designed for the ARRMA 1/10 Kraton 4S and ARRMA 1/10 Outcast 4S 4X4 models. They are listed as both standard parts and optional tuning parts for these vehicles, meaning they come fitted as original equipment but can also be swapped for alternative spring rates as part of suspension tuning.
- What spring rate options are available for ARRMA 1/10 trucks? — ARRMA offers shock springs in multiple rates for their 1/10 vehicles. The 1.00N/mm (5.71lb/in) springs in this product are a medium rate option. Other available rates include 70mm 1.34N/mm (7.65lb/in) for stiffer tuning and 70mm 1.16N/mm (6.62lb/in) as an alternative option, allowing you to progressively adjust your suspension stiffness based on track conditions and driving style.
- How do I change the shock springs on my ARRMA RC truck? — Whilst specific installation instructions aren't included in the product information, shock spring replacement on most RC vehicles is a straightforward procedure that typically involves removing the shock body from the vehicle and extracting the old spring before inserting the new one. This is one of the quickest suspension modifications you can perform.
- Why would I want to change my shock springs? — Springs soften over time and lose their original rate, causing your vehicle to sit lower and handle differently than intended. Upgrading to new springs restores your suspension geometry and handling characteristics. Additionally, switching to different spring rates allows you to adapt your vehicle's performance to different track conditions, weather, and driving styles without purchasing a completely new RC truck.
- Are these genuine ARRMA parts? — Yes, these are official ARRMA manufacturer components (part number ARA330762 or Z-ARA330762), not aftermarket alternatives. Using genuine parts ensures perfect fitment and maintains the engineering integrity of your vehicle.
- How many shock springs do I need? — A complete suspension typically uses four shock springs (two front, two rear). This product contains two springs, so you may need to purchase multiple packs depending on whether you're replacing just one end or doing a complete suspension refresh. Alternatively, you can purchase one pack for one end and experiment with different rates.
