Overview
The ARRMA Aluminum Shock Set is a premium replacement suspension upgrade designed specifically for the 1/16 scale GROM family of RC monster trucks. This assembled shock set represents a significant step up from kit-supplied items, offering higher-quality materials and pre-configured performance that enthusiasts across the UK have come to trust from ARRMA's engineering. Whether you're running an ARRMA GORGON GROM or QUAKE GROM 4x4, these 71mm aluminium shocks provide the reliability and adjustability that serious bashers and weekend warriors demand from their RC car UK setup.
Pre-filled with 500 cSt silicone shock oil and ready to bolt straight onto your vehicle, this four-piece shock set eliminates the hassle of having to source oil separately or spend time assembling shocks from bare components. The set comes with all four shocks you need to completely upgrade your vehicle's suspension system, making it the ideal choice for anyone looking to improve their GROM's handling characteristics without investing in a complete chassis overhaul. These assembled shocks are manufactured to ARRMA's exacting standards and represent genuine factory components designed to work in perfect harmony with your ready to run RC monster truck.
With threaded spring preload adjusters integrated into each shock, you'll have fine-tuning capability at your fingertips to dial in your ride height exactly as you prefer it. This level of adjustability is something many basher-grade RC vehicles simply don't offer, allowing you to adapt your suspension geometry to different terrain types, track conditions, or driving styles throughout a single day's bashing session.
Key Features
- Aluminium construction — The shock bodies are manufactured from high-grade aluminium alloy, which provides superior rigidity and durability compared to plastic alternatives whilst keeping weight to a minimum, ensuring your GROM maintains excellent handling balance and responsiveness.
- 71mm length specification — These shocks are precisely engineered to the 71mm length required by GROM variants, ensuring perfect fitment and maintaining the correct ride height geometry for optimal suspension performance and ground clearance.
- Pre-filled with 500 cSt silicone oil — Each shock arrives pre-filled with 500 cSt silicone shock oil, which provides the correct damping characteristics for GROM models straight out of the box, eliminating the need to purchase oil separately or wait for the shocks to be prepared before installation.
- Fully assembled and ready to install — Unlike bare shock components that require assembly, these shocks come completely assembled and tested, allowing you to bolt them directly onto your vehicle and get back to bashing within minutes rather than spending hours on preparation.
- Threaded spring preload adjusters — Each shock features threaded preload adjustment rings that allow you to raise or lower your vehicle's ride height with precision, giving you control over suspension geometry for different driving conditions, jumping angles, and handling characteristics.
- Four-piece set for complete suspension upgrade — This set includes all four shocks needed to fully replace your vehicle's suspension system, ensuring consistent performance across all corners and eliminating the need to source shocks from multiple suppliers.
- OEM ARRMA quality — As genuine ARRMA factory components, these shocks are manufactured to the same standards as those supplied in fresh-out-of-the-box ready to run RC trucks, guaranteeing compatibility and reliability with your GROM platform.
Technical Performance
The ARRMA Aluminum Shock Set represents a significant performance improvement for GROM owners looking to upgrade their suspension without replacing the entire chassis. The 71mm length has been specifically engineered to work with the GROM's geometry, maintaining the correct anti-dive and anti-squat characteristics whilst providing the suspension travel needed for aggressive bashing across varied terrain. The aluminium construction delivers superior stiffness compared to plastic alternatives, reducing flex and providing more consistent, predictable handling throughout a bashing session. The 500 cSt silicone oil fill provides medium-rate damping that balances responsiveness with bottoming-out resistance, making these shocks suitable for both smooth tarmac and rough off-road surfaces typical of UK garden gardens, parks, and terrain. The threaded preload adjusters offer infinite adjustment between fully compressed and fully extended spring positions, allowing you to fine-tune everything from jump landing characteristics to high-speed stability. Unlike cheaper shock alternatives, the fully assembled design means the internals have been precisely configured by ARRMA engineers, with properly matched springs and valving to work together as a system rather than individual components. The result is suspension geometry that maintains optimal ride height, consistent body roll characteristics through corners, and predictable damping feedback that allows you to confidently push your GROM to its limits whether you're bashing around obstacles or jumping off naturally formed ramps.

Frequently Asked Questions
- Will these shocks fit my GROM RC monster truck? — Yes, these shocks are specifically designed for GROM variants and will fit all GORGON GROM and QUAKE GROM 4x4 RTR models. They are confirmed compatible with the C-ARA2130T2, C-ARA2130T1, C-ARA2130T3, C-ARA2137T2, C-ARA2137T1, and C-ARA2137T3 GROM models available in the UK.
- Are these shocks pre-filled and ready to use immediately? — Absolutely. These shocks come fully assembled and pre-filled with 500 cSt silicone oil, meaning you can install them directly onto your GROM without any additional preparation, oil filling, or assembly work. Simply unbolt your old shocks and bolt these new ones on.
- What is the benefit of upgrading from kit-supplied shocks? — Kit-supplied shocks are often manufactured to cost targets rather than performance standards. These genuine ARRMA shocks feature higher-quality aluminium construction, superior internal engineering, and better oil formulation. The result is more consistent damping, better handling, improved durability, and the ability to adjust ride height precisely using the threaded preload adjusters.
- Can I adjust the ride height on these shocks? — Yes, each shock features threaded spring preload adjusters that allow you to easily raise or lower your vehicle's ride height. This adjustment capability lets you fine-tune your GROM's suspension geometry for different terrain types, jumping angles, or driving conditions throughout a single day's bashing.
- What does the 500 cSt oil specification mean? — The cSt (centistoke) measurement indicates the thickness or viscosity of the shock oil. 500 cSt represents a medium-rate damping oil that balances responsiveness with resistance to bottoming out. This specification has been chosen by ARRMA as the ideal starting point for GROM performance across varied terrain.
- Are these suitable for beginners? — Yes, these shocks are ideal for beginners because they arrive fully assembled and ready to install, requiring no technical knowledge beyond basic bolt removal and installation. However, the threaded preload adjusters also provide room for more advanced tuning as your skills develop, making these shocks a worthwhile investment that will grow with your RC experience.
- How do I install these shocks on my GROM? — Installation is straightforward and typically requires only basic tools like hex drivers or socket wrenches to unbolt the old shocks and install the new ones. Detailed installation instructions should be consulted for your specific GROM model variant, but the process is within the capability of any RC enthusiast with basic mechanical skills.
