Overview
The ARRMA Alum Shock Set represents a premium suspension upgrade solution for RC enthusiasts looking to enhance their vehicle's performance and handling characteristics. This pair of assembled aluminium shock absorbers comes filled with high-quality 500cSt silicone shock oil, delivering the fast and efficient suspension upgrade your RC car UK needs to perform at its best. Whether you're upgrading from stock suspension on your ARRMA stadium truck or fine-tuning an existing setup, these shocks provide the foundation for exceptional ride quality and responsiveness on the track or during freestyle bashing sessions.
Designed with precision engineering and attention to detail, these shocks feature an 11mm internal bore diameter with an 87mm centre-to-centre length, making them compatible with a range of ARRMA models including the 1/10 Vorteks series. The shocks arrive fully assembled and ready to bolt onto your vehicle after you select and fit your choice of springs, eliminating the hassle of manual assembly and ensuring consistent quality from the moment you open the box. For RC enthusiasts in the UK seeking performance upgrades for their brushless RC stadium trucks and other four-wheel-drive models, this shock set delivers genuine value and measurable improvements in suspension response.
The inclusion of multiple tuning preload spacers means you're not locked into a single setup—instead, you gain the flexibility to adjust your suspension geometry and characteristics to suit different track conditions, driving styles, and terrain types. This versatility makes the ARRMA shock set an intelligent investment for anyone serious about optimising their RC vehicle's performance, whether you're competing at a local club or enjoying weekend bashing at your favourite spot.
Key Features
- High-quality anodised aluminium shock bodies — The anodised aluminium construction provides excellent durability and corrosion resistance whilst keeping weight to a minimum, ensuring your RC car maintains optimal handling balance without unnecessary mass in the suspension system.
- Tough molded shock caps, shock seal cartridges and preload adjusters — These precision-engineered components work together to create a reliable seal that prevents oil leakage whilst enabling smooth and consistent damping action throughout the shock's travel range.
- Strong 3mm stainless steel shock shafts — The substantial stainless steel shafts resist bending and corrosion, providing long-lasting durability even under the demanding conditions of competitive racing or aggressive bashing with your brushless RC model.
- Tough composite shock rod ends, spring retainers and pivot balls — These composite materials combine strength with light weight, maintaining precise geometry whilst reducing unsprung mass that could compromise handling response and traction.
- Smooth silicone o-rings — The silicone o-rings provide a consistent, reliable seal that prevents damping fluid from escaping whilst maintaining smooth operation across varying temperatures and driving conditions throughout the year.
- Supplied fully assembled and ready to bolt on — Receiving your shocks fully assembled eliminates build time and ensures factory-quality assembly, allowing you to focus on fitting springs and getting your RC vehicle on the track without delay.
- 500cSt silicone shock oil included — The pre-filled high-quality silicone shock oil ensures immediate optimal damping characteristics right out of the box, with the specific viscosity tuned to deliver predictable and responsive suspension behaviour.
- Additional tuning preload spacers supplied — You receive 2mm, 5mm, and 7mm preload spacers in pairs, enabling you to fine-tune your ride height and suspension geometry to match track conditions, driving style, and vehicle setup preferences.
Technical Performance
These aluminium shocks represent a significant step up from many standard suspension systems, combining precision engineering with premium materials throughout. The 11mm bore diameter provides the internal space required for smooth damping action, whilst the 1.3mm piston with 2 holes ensures consistent oil bypass characteristics across the shock's full range of motion. The 87mm centre-to-centre length integrates seamlessly with ARRMA's suspension geometry, maintaining the intended suspension angles and ride height whilst the 3mm stainless steel shafts deliver exceptional strength-to-weight ratio. The 500cSt silicone oil specification has been carefully selected to provide responsive damping that suits a broad range of driving conditions and skill levels, making these shocks equally at home on a technical club track or during casual outdoor bashing sessions. The anodised aluminium body construction not only looks premium but also resists corrosion from moisture and salt, extending the working life of your suspension components even in challenging UK weather conditions. Build quality throughout is exceptional, with tight tolerances and precision machining evident in every component from the molded shock caps to the preload adjusters, ensuring consistent performance lap after lap or run after run.

Frequently Asked Questions
- What vehicles are these ARRMA shocks compatible with? — These 11mm bore, 87mm length shocks are listed as compatible with the 1/10 ARRMA Vorteks range, including the Vorteks 223S 4x4 RTR Brushless Stadium Truck, Vorteks 2WD RTR Brushed Stadium Truck, and Vorteks 3S 4x4 RTR Brushless Stadium Truck. Always verify compatibility with your specific model before ordering.
- Do these shocks come assembled? — Yes, the shocks arrive completely assembled and filled with 500cSt silicone oil, ready to bolt onto your vehicle after you select and fit suitable springs. This saves significant build time and ensures factory-quality assembly standards.
- What springs do I need to use with these shocks? — The shocks require springs to be fitted; ARRMA recommends springs such as the ARA330712 Shock Springs which measure 55mm with a spring rate of 1.2N/mm (6.9lbf/in). Springs are sold separately and must be selected based on your vehicle weight and driving conditions.
- How do the preload spacers affect performance? — The included 3mm, 5mm, and 7mm preload spacers allow you to adjust ride height and suspension geometry without replacing springs. Adding spacers reduces overall suspension travel slightly and increases the spring pre-compression, enabling fine-tuning to suit different track conditions and driving styles.
- What makes 500cSt oil suitable for my RC car? — The 500cSt viscosity has been specifically selected to provide responsive damping that works well across a variety of conditions and skill levels. The silicone formulation resists temperature changes, maintaining consistent performance whether you're driving during UK summer heat or cooler autumn sessions.
- Can I change the shock oil? — Whilst these shocks arrive pre-filled with quality 500cSt silicone oil, they are serviceable components. However, this requires disassembly and should only be attempted by experienced builders with appropriate tools and knowledge of shock servicing procedures.
- Are these suitable for beginners? — Yes, these shocks are excellent for beginners as they arrive fully assembled and ready to install. The included preload spacers provide simple tuning options without requiring advanced mechanical knowledge, making them accessible to newcomers to the RC hobby.
- What is the difference between these and stock ARRMA shocks? — These premium aluminium shocks represent a significant upgrade from many standard ARRMA shocks, featuring anodised aluminium bodies, stainless steel shafts, quality silicone seals, and precision-engineered components throughout. The anodised finish offers superior corrosion resistance and durability, whilst the stainless steel construction ensures long-lasting reliability under demanding use.
- How often should I service these shocks? — Regular maintenance depends on usage frequency and conditions. After significant use, especially in wet or dusty conditions, you may wish to have shocks professionally serviced to replace seals and refresh the damping oil, maintaining optimal performance and reliability.
