Overview
The ARRMA Aluminum Shock Set, 58mm Length, 300cSt Oil (4) for GROM is a premium suspension upgrade and replacement component designed to keep your RC car performing at its absolute best. Whether you're a dedicated RC enthusiast in the UK, a weekend basher enjoying your favourite hobby, or someone looking to maintain their ready to run RC vehicle, this assembled shock set delivers the quality and performance you expect from ARRMA. These are genuine OEM parts that replace the factory-supplied shocks on compatible GROM models, ensuring your vehicle maintains its handling characteristics and ride quality through countless hours of driving.
This comprehensive shock set is ideal for RC car enthusiasts who want to maintain peak suspension performance, fine-tune their vehicle's handling, or simply replace worn components with factory-quality parts. The pre-filled, ready-to-bolt-on design means you don't need specialist tools or knowledge to install them—making them accessible to beginners and experienced RC hobbyists alike. With four complete assembled shock absorbers included, you have everything needed to refresh your GROM's entire suspension system in one purchase.
ARRMA is renowned throughout the RC car UK community for producing durable, high-performance vehicles and components, and this shock set is no exception. The combination of premium aluminium construction and precision engineering means these shocks will withstand the demands of aggressive driving, jumps, and technical terrain whilst maintaining consistent performance lap after lap.
Key Features
- Aluminium construction — The shock bodies are manufactured from high-quality aluminium, providing an excellent balance between lightweight design and rigidity, which means your suspension components won't flex under load and will respond predictably to terrain changes.
- Pre-filled with 300cSt silicone shock oil — These shocks arrive pre-filled with precisely-tuned 300cSt silicone shock oil, which damps suspension movement smoothly and protects internal components from wear, eliminating the need for you to source and fill oil yourself.
- Assembled and ready to install — Each shock absorber comes fully assembled with all internal components in place, allowing you to simply bolt them onto your vehicle without any additional preparation or assembly work.
- Threaded spring preload adjusters — Fine-tune your vehicle's ride height and suspension geometry with ease using the threaded spring preload adjusters, giving you the ability to dial in the perfect setup for different driving conditions and track layouts.
- Set of four units — You receive four complete shock absorbers, providing replacement for all four corners of your GROM and ensuring consistent suspension performance across the entire vehicle.
- OEM quality and compatibility — These are genuine ARRMA parts designed specifically for GROM models, guaranteeing perfect fitment and maintaining your vehicle's original handling characteristics.
Technical Performance
The 58mm length specification is precisely engineered for GROM-scale vehicles, providing the optimal suspension travel and response for these compact, hard-hitting RC machines. The 300cSt oil viscosity strikes an ideal balance for general-purpose driving, offering adequate damping for both high-speed runs and technical rock-crawling without being so stiff that it creates harsh, jarring feedback over bumpy terrain. The aluminium construction provides superior corrosion resistance compared to steel alternatives, which is particularly valuable if you intend to drive your RC car near water or in damp UK conditions. The threaded preload adjusters allow suspension tuning without requiring complete shock disassembly, meaning you can experiment with different ride heights and spring tensions to match your driving style and terrain preferences. Whether you favour smooth tarmac circuits, bumpy grass fields, or mixed terrain scrambling, these shocks provide the engineering foundation for excellent handling. The silicone oil filling is sealed within the shock bodies to prevent leakage and contamination, maintaining consistent damping characteristics even during extended driving sessions or after aggressive impacts.

Frequently Asked Questions
- Are these ARRMA shocks compatible with all GROM models? — These shocks are specifically designed for GROM vehicles. According to ARRMA's compatibility information, they fit the following models: GRANITE GROM MEGA 380 (1/18 scale in multiple colours), MOJAVE GROM 223S BLX (1/16 scale), MOJAVE GROM MEGA 380 (1/16 scale), and TYPHON GROM 223S BLX and MEGA 380 variants (1/14 scale). Before ordering, verify your specific GROM model matches one of these variants to ensure proper fitment.
- Do I need any tools or technical knowledge to install these shocks? — No, these shocks are supplied fully assembled and ready to bolt on. You'll need basic RC tools such as a hex wrench or screwdriver to remove your old shocks and install the new ones, but no specialist knowledge or internal assembly is required. Most RC enthusiasts can complete the installation in under an hour.
- What does 300cSt oil viscosity mean for my driving experience? — The 300cSt rating describes how thick the silicone oil is inside the shocks. Thicker oil (higher cSt rating) creates stiffer damping and a harsher ride, whilst thinner oil allows more suspension movement. The 300cSt specification provides a balanced, all-purpose damping rate suitable for diverse driving conditions, from smooth tracks to rough grass terrain. If you find the ride too harsh, ARRMA offers lighter oil options; if it's too soft, you can upgrade to higher viscosity shocks.
- Can I adjust the ride height with these shocks? — Yes, the threaded spring preload adjusters allow you to modify ride height by compressing or extending the springs. Simply rotate the adjusters to change the pre-compression of the springs, which alters both the ride height and the suspension's initial response. This adjustment is a fundamental tuning tool that lets you dial in your vehicle's handling without purchasing new shocks.
- Why would I need replacement shocks? — Shock absorbers wear over time due to repeated compression cycles, dirt ingestion, and impact damage from jumps and rough terrain. If your vehicle exhibits harsh, bouncy handling, uneven ride height between corners, or visible leaking from shock bodies, it's time to replace them. These genuine ARRMA parts restore your vehicle to factory performance specifications.
- Is this suitable for beginners? — Absolutely. These are genuine replacement parts that arrive fully assembled, making installation straightforward for newcomers to the RC hobby. The pre-filled oil means you don't need to understand oil viscosity or undertake messy filling procedures. Beginners will appreciate the ready-to-install convenience whilst still gaining valuable experience in basic vehicle maintenance and suspension tuning.
- How do these compare to the standard shocks that come with a GROM? — These are the same quality components that ARRMA uses in their factory builds. When you purchase them separately as a tune-up set, you're getting genuine OEM parts rather than potentially discounted or older stock. They're ideal for replacing worn factory shocks or maintaining consistency across your vehicle's suspension when one shock has been damaged.
