Key Features
- High-quality anodised aluminium shock bodies — The use of anodised aluminium provides excellent corrosion resistance and a premium finish that will look great on your RC car whilst maintaining structural integrity through years of use. Anodising creates a protective oxide layer that guards against oxidation and wear, ensuring your shocks maintain their performance characteristics even after extensive driving sessions.
- Strong 3mm stainless steel shock shafts — The oversized 3mm stainless steel shafts deliver exceptional durability and resistance to bending or damage during aggressive driving or crashes. Stainless steel resists corrosion from moisture and dirt, ensuring smooth operation even in damp UK conditions, which is critical for maintaining consistent damping performance throughout the shock's lifespan.
- Pre-filled with 500cSt silicone shock oil — The inclusion of high-quality 500cSt silicone shock oil means these shocks arrive ready to use without requiring you to source and fill oil separately. This viscosity level provides a good balance between damping control and responsiveness, making it suitable for a wide variety of driving conditions and skill levels.
- Tough molded shock caps and seal cartridges — The precision-moulded shock caps and integrated seal cartridges prevent oil leakage and maintain consistent damping performance over extended use. Quality seal design is critical for reliability, as even small leaks can compromise the shock's tuning characteristics and lead to inconsistent handling.
- Tough composite shock rod ends, spring retainers and pivot balls — The use of durable composite materials for these wear components reduces weight compared to metal alternatives whilst maintaining excellent strength and reliability. Composite rod ends provide smooth articulation and resist corrosion, ensuring your suspension geometry remains consistent throughout your driving sessions.
- Smooth silicone o-rings — Premium silicone o-rings throughout the shock assembly provide reliable sealing and smooth operation, preventing premature wear and maintaining the integrity of the damping characteristics over time. Quality seals are essential for preventing dust and moisture ingress, which can degrade shock performance.
- Supplied assembled and ready to bolt on — These shocks arrive fully assembled, meaning you simply need to fit your choice of springs before installation. This saves considerable time compared to building shocks from individual components and reduces the risk of assembly errors that could compromise performance.
- 1.3mm x 2-hole pistons — The precision-engineered 1.3mm pistons with two damping holes are optimised for balanced suspension response, controlling compression and rebound movement smoothly. The two-hole design allows oil to flow through both holes, providing progressive damping that helps maintain traction whilst absorbing impacts effectively.
- Additional tuning preload spacers supplied — Three different preload spacer options (3mm, 5mm, and 7mm) are included, allowing you to fine-tune your vehicle's ride height and suspension geometry. This gives you the flexibility to adjust your shocks to match your driving style, track conditions, and vehicle setup preferences without purchasing additional components.
Technical Performance
The ARRMA Alum Shock Set represents serious engineering designed to handle the demands of modern RC racing and high-performance driving. With an 11mm internal bore diameter, these shocks provide a balance between strength and weight, whilst the 103mm centre-to-centre length makes them compatible with a comprehensive range of ARRMA vehicles. The 500cSt silicone shock oil provides the ideal viscosity for responsive damping without being overly stiff, making these shocks suitable for both competitive drivers and casual enthusiasts exploring the world of RC vehicles in the UK. The 1.3mm x 2-hole piston design has been proven to deliver consistent, predictable suspension behaviour across various driving speeds and impact scenarios. Build quality is exceptional throughout, with every component manufactured to precise tolerances to ensure reliability and consistent performance. The anodised aluminium bodies resist the wear and tear of regular use, whilst the stainless steel shafts offer superior corrosion resistance compared to standard steel alternatives. Whether you're driving on tarmac, grass, or dirt, these shocks will maintain their performance characteristics and continue to deliver responsive, controlled suspension action that translates directly to improved handling and faster lap times. The engineering philosophy behind these shocks emphasises durability without compromising the responsiveness that serious drivers demand from their suspension systems.
