Overview

The ARRMA Shock Set with 11mm bore and 87mm length is an essential replacement suspension component for RC enthusiasts maintaining or upgrading their ARRMA models. This assembled front shock set provides ideal replacement parts for kit-supplied items, delivering premium performance and durability for both weekend bashers and serious RC car UK hobbyists. Whether you're replacing worn suspension components or fine-tuning your ready to run RC vehicle's handling characteristics, this shock set represents genuine ARRMA quality engineering.

Designed specifically for ARRMA's 1/10 scale stadium trucks and other compatible models, these shocks come pre-assembled and pre-filled, eliminating the need for complex setup procedures. The high-quality construction ensures consistent performance across varied terrain, from smooth tarmac to rough off-road courses. This makes the shock set particularly valuable for anyone looking to maintain their RC car's suspension performance or upgrade from standard kit-supplied components.

Perfect for RC model enthusiasts across the UK seeking reliable, manufacturer-approved suspension upgrades, this shock set combines ease of installation with proven performance credentials. The ready-to-install nature of these assembled shocks means you can have your vehicle back on the track quickly, making this an excellent choice for competitive drivers and casual hobbyists alike.

Key Features

• Pre-filled with 500cSt silicone shock oil — The shocks arrive pre-filled with premium 500cSt silicone shock oil, eliminating the need to source and install oil separately and ensuring optimal damping performance immediately upon installation.
• Supplied assembled without springs — Each shock arrives fully assembled with no springs included, allowing you to select your preferred spring rate (#ARA330712 springs are required separately) to perfectly tune your vehicle's ride height and handling characteristics.
• 11mm bore diameter — The 11mm bore specification provides the precise internal dimensions needed for compatibility with ARRMA suspension systems and ensures proper piston engagement and smooth damping action.
• 87mm total length — This specific length measurement ensures perfect fitment with compatible ARRMA models including the 1/10 VORTEKS series, maintaining correct suspension geometry and ride height.
• Spring spacers included for ride height adjustment — The included spring spacers allow fine-tuning of your vehicle's ride height, giving you the flexibility to optimise ground clearance and suspension travel for different driving conditions and track layouts.
• High-quality materials throughout — ARRMA's reputation for engineering excellence is evident in the quality materials used in these shock bodies and internal components, delivering reliability and longevity even under demanding use.
• Ready to bolt on after spring fitting — Once you've selected and installed your choice of springs (via the separately available spring kit), these shocks are immediately ready to install on your vehicle with no further modification required.
• Set of 2 assembled shock absorbers — This package includes two complete shock units, providing the front suspension pair needed for most ARRMA RC car setups.

Technical Performance

The ARRMA Shock Set represents serious suspension engineering designed for 1/10 scale RC vehicles. The 11mm bore diameter is a critical specification that determines piston size and oil flow rates, directly affecting how your RC car handles bumps, jumps and cornering forces. The 87mm length positions these shocks specifically for front suspension applications on compatible ARRMA models such as the 1/10 VORTEKS 3S 4X4 RTR and 1/10 VORTEKS BOOST 2WD variants. The pre-filled 500cSt silicone shock oil provides the correct viscosity for balanced damping characteristics—thick enough to absorb impacts effectively but fluid enough to allow quick suspension movement during rapid terrain changes. This oil viscosity is industry-standard for 1/10 scale vehicles and ensures consistent performance across temperature ranges typical in UK climate conditions. The assembled construction means precision machining and internal component quality control have already been completed to ARRMA's exacting standards, guaranteeing proper piston rod alignment, seal integrity and smooth operation. These shocks work as a critical component of your vehicle's overall suspension system, controlling weight transfer during acceleration and braking whilst maintaining tyre contact through uneven terrain. For serious RC enthusiasts in the UK seeking reliable replacement or upgrade suspension, this shock set delivers engineering quality that translates directly to improved handling, better traction and longer component lifespan compared to worn original equipment.

Frequently Asked Questions

• Are these shocks compatible with my ARRMA RC car? — These shocks are designed as standard parts for the ARRMA 1/10 VORTEKS 3S 4X4 RTR brushless stadium truck and 1/10 VORTEKS BOOST 2WD variants. They're also listed as optional parts for these models, meaning they provide superior performance compared to kit-supplied items. Check your vehicle's manual or ARRMA parts diagram to confirm compatibility with your specific model.
• What oil viscosity do these shocks contain? — These shocks are pre-filled with 500cSt silicone shock oil, which is a medium viscosity suitable for balanced damping performance in 1/10 scale vehicles across typical UK driving conditions and temperatures.
• Do I need springs to use these shocks? — Yes, springs are sold separately. The ARRMA Shock Springs #ARA330712 (55mm, 1.2N/mm rating) are recommended for use with these shock bodies. The supplied spring spacers allow you to adjust ride height once springs are installed.
• What is the 11mm bore measurement? — The bore refers to the internal diameter of the shock cylinder where the piston rod moves. At 11mm, this is the correct specification for these particular shock units and must match your vehicle's suspension design for proper fitment and performance.
• Are these shocks pre-assembled? — Yes, these arrive fully assembled with internal components, seals and rod already installed. You simply need to add your choice of spring and bolt them onto your vehicle—no disassembly or internal setup is required.
• How do spring spacers affect my vehicle's handling? — Spring spacers allow you to adjust where the spring sits on the shock body, effectively changing your vehicle's ride height. Lowering ride height increases ground clearance and can change weight distribution; raising it affects suspension geometry and can alter cornering behaviour.
• Is this suitable for beginners? — Yes. Since these shocks arrive assembled and pre-filled, installation is straightforward—simply bolt them on after fitting springs. This makes them ideal for RC beginners looking to maintain or upgrade their vehicle without dealing with internal shock assembly or oil filling.
