Overview
The ARRMA Shock Set with 15mm bore and 111mm length is a premium suspension component designed for serious RC enthusiasts running high-performance brushless RC vehicles. This complete shock absorber set provides a ready-to-install solution for maintaining or upgrading the suspension on your ARRMA 4X4 RC truck, ensuring optimal handling and performance on any terrain. Whether you're a competitive racer, weekend basher, or dedicated hobbyist exploring the world of RC car UK culture, quality shocks are essential for maintaining your vehicle's performance and longevity.
This shock set comes fully assembled and pre-filled with high-quality 500cSt silicone shock oil, eliminating the need for time-consuming assembly and fluid filling. The shocks are engineered to deliver smooth suspension action, precise handling characteristics, and durability that matches the demands of modern brushless RC trucks. With a reputation for excellence in the RC community, ARRMA has designed these shocks to work seamlessly with their latest generation of 4S brushless RC vehicles.
What sets this shock set apart is the comprehensive package of included tuning components and robust construction methods. You're getting not just replacement shocks, but a fully customisable suspension solution with multiple preload spacer options to dial in your preferred ride height and handling balance. Whether you're preparing for competition or simply maintaining your ready to run RC truck, this is a professional-grade component that delivers genuine performance improvements.
Key Features
- High-quality anodised aluminium big bore shock bodies — The 15mm bore diameter provides increased volume for the suspension fluid, which translates to more consistent damping performance and better heat dissipation during extended running sessions. Anodised aluminium offers excellent corrosion resistance and durability, essential for vehicles that may encounter moisture or salt spray in UK outdoor environments.
- Strong 4mm stainless steel shock shafts — The thick stainless steel shaft construction ensures long-lasting durability and resistance to bending or failure, even under the extreme stresses of high-speed running and aggressive landings. Stainless steel resists rust and corrosion, maintaining smooth operation over many seasons of use.
- Tough molded shock caps, shock seal cartridges and preload adjusters — These precision-molded components work together to maintain consistent seal integrity, prevent fluid leakage, and allow for easy preload adjustment without the need for additional tools or modifications.
- Tough composite shock rod ends, spring retainers and pivot balls — The composite construction of these connection points provides the perfect balance between strength and weight savings, while maintaining smooth articulation and preventing binding in the suspension movement.
- Smooth silicone o-rings — Premium silicone o-rings ensure excellent sealing properties and smooth piston movement throughout the shock stroke, maintaining consistent damping feel and preventing oil leakage that could compromise performance.
- Pre-filled with 500cSt silicone shock oil — The shocks arrive completely assembled and filled with professional-grade silicone oil, ready to bolt straight onto your vehicle without any additional preparation or risk of installation errors.
- Supplied assembled and ready to bolt on — Save valuable setup time with fully assembled shocks that require no internal modifications or fluid filling, allowing you to get back to running your RC truck immediately.
- Additional tuning preload spacers supplied — This shock set includes six preload spacers in three different thicknesses (2 x 3mm, 2 x 5mm, and 2 x 7mm), giving you multiple options to fine-tune your suspension geometry and ride height for different track conditions or personal preferences.
Technical Performance
These ARRMA shocks represent professional-grade suspension engineering designed specifically for the demands of modern brushless RC 4X4 trucks and stunt vehicles. The 111mm centre-to-centre length and 15mm internal bore diameter are precision specifications that ensure perfect compatibility with ARRMA's current generation of vehicles including the Kraton and Outcast 4S models. The 1.3mm x 4 hole piston design provides carefully calibrated damping characteristics, offering the ideal balance between responsiveness and stability. The 500cSt silicone shock oil provides medium damping resistance suitable for general-purpose running, delivering smooth suspension action across varied terrain. The construction combines aluminium bodies with stainless steel shafts and composite connection points, resulting in a shock absorber that is simultaneously lightweight, durable, and corrosion-resistant. Whether you're running on tarmac, grass, dirt, or in wet UK weather conditions, these shocks are engineered to deliver consistent performance and maintain their functionality season after season. The comprehensive preload spacer kit allows you to adjust the suspension geometry to suit your personal driving style and the specific conditions of your local RC track or running area.

Frequently Asked Questions
- What ARRMA vehicles are these shocks compatible with? — These shocks are standard parts for the ARRMA 1/10 Kraton 4S V2 4X4 RTR Brushless Speed Monster Truck and the ARRMA 1/10 Outcast 4S V2 4X4 RTR Brushless Stunt Truck. They are designed as direct replacement components for these models, though they may also fit other ARRMA vehicles with compatible suspension mounting points.
- Do these shocks come pre-assembled and filled? — Yes, absolutely. These shocks arrive completely assembled with the 500cSt silicone shock oil already installed, eliminating the need for any internal assembly work or fluid filling. You simply fit your chosen springs and bolt them directly onto your vehicle.
- What oil viscosity do these shocks contain? — The shocks are pre-filled with 500cSt silicone shock oil, which provides medium damping resistance. This viscosity is suitable for general-purpose running and works well for both indoor and outdoor environments. If you prefer a different damping characteristic, you can purchase alternative viscosity oils separately from ARRMA.
- How do the preload spacers affect my vehicle's handling? — The preload spacers adjust the amount of spring preload, which affects your vehicle's ride height and how much of the suspension stroke is used during normal operation. Using different spacer thicknesses allows you to fine-tune the suspension geometry for different track conditions, personal preferences, or driving styles. More preload raises the ride height and reduces suspension travel, whilst less preload lowers the vehicle and increases suspension travel available.
- What springs do I need to fit to these shocks? — ARRMA supplies three different spring rate options: part numbers ARA330758, ARA330759, and ARA330760. The correct spring for your vehicle depends on your weight, driving style, and the conditions you typically run in. Check your vehicle's manual or contact ARRMA support to determine which spring rate is most suitable for your situation.
- Are these suitable for a beginner to RC? — Yes, these shocks are suitable for beginners to the RC hobby, provided your vehicle is a compatible ARRMA model. The shocks arrive fully assembled and ready to use, requiring no technical knowledge to install. However, you should have basic mechanical skills to remove and fit suspension components, or be prepared to learn these skills as part of your RC experience.
- Why should I replace my original shocks? — Over time, shock absorbers can wear out, lose oil, or develop seal leaks that compromise suspension performance. Replacing your shocks restores the handling characteristics of your vehicle and can improve acceleration, cornering, and landing performance. Additionally, upgrading to fresh shocks is a good maintenance practice for vehicles that see regular use.
