Overview

The Fastrax Arrma Grom/Granite/Mojave Aluminium Shock Set offers UK RC enthusiasts a premium suspension upgrade that transforms the handling characteristics of these popular small-scale RC monster trucks. Whether you're a seasoned basher looking to fine-tune your rig or someone new to the world of RC car customisation, this four-piece shock absorber set delivers the quality engineering and performance you'd expect from a trusted brand in the RC hobby market. These aluminium shocks are specifically engineered to work seamlessly with Arrma's compact but capable truck range, giving you the ability to dial in precisely the suspension characteristics your driving style demands.

Built with durability and precision in mind, this shock set represents excellent value for money and a straightforward upgrade path for anyone running Arrma's 1/18 and 1/16 scale models. The blue colour scheme complements the factory aesthetics of these trucks while the aluminium construction ensures long-lasting performance through countless sessions of off-road bashing. If you're serious about getting the most from your RC car in the UK, suspension upgrades are one of the most effective investments you can make, and this Fastrax set makes that upgrade accessible and hassle-free.

RC suspension tuning has always been the domain of serious competitors, but modern retailers and manufacturers have made it easier than ever for hobby enthusiasts to access quality components. This shock set exemplifies that democratisation of performance—it's the kind of upgrade that separates casual bashers from those who truly understand their machine and want to optimise every aspect of its behaviour.

Key Features

• Premium Aluminium Construction — The shock bodies are manufactured from high-quality aluminium, which provides an excellent strength-to-weight ratio whilst maintaining the durability needed for regular RC car use. Aluminium is significantly stiffer and more durable than plastic alternatives, meaning your shocks will maintain their performance characteristics over extended periods of use and won't degrade through flexing or impact damage.
• Complete Four-Piece Set — This set includes all four shocks needed to equip your Arrma monster truck, eliminating the need to purchase components individually. Having matched shocks across all corners ensures consistent handling balance and allows you to fine-tune your truck's ride height and spring rates with confidence that the geometry remains symmetrical.
• Precision Engineering — Fastrax is a recognised brand in the RC hobby space, known for producing high-quality aftermarket parts that meet exacting standards. These shocks have been engineered specifically for compatibility with Arrma's Grom, Granite, and Mojave models, meaning fitment is guaranteed and performance is optimised for these platforms.
• Enhanced Handling and Control — Upgrading to quality aluminium shocks from factory components typically results in improved suspension response, better bump compliance, and more predictable handling characteristics. This translates to better cornering performance, improved stability over rough terrain, and a more enjoyable driving experience whether you're bashing casually or pushing harder.
• Easy Installation — These shocks are designed as a direct replacement for the factory units on compatible Arrma models, meaning installation requires only basic RC car knowledge and standard tools. No extensive modifications or custom work are needed—simply remove the old shocks and install the new ones.
• Tuning Capability — Quality shocks like these allow you to experiment with different oils and spring rates, opening up a world of suspension tuning possibilities. As you develop your RC car skills, you'll be able to fine-tune your truck's behaviour to suit different driving styles, track conditions, and weather.

Technical Performance

The Fastrax Arrma Grom/Granite/Mojave Aluminium Shock Set represents a genuine engineering upgrade over factory plastic suspension components. Aluminium construction offers superior rigidity compared to polymer shocks, which means the shock bodies won't flex under load, maintaining precise geometry and consistent damping characteristics throughout your driving session. This is particularly important in small-scale RC trucks like the 1/18 Granite Grom and 1/16 Mojave Grom, where suspension performance directly impacts handling precision and off-road capability. The shock set's compatibility with Arrma's brushed and brushless variants—including the Granite Grom MEGA 380 Brushed 4x4, the Mojave Grom MEGA 380 Brushed 4x4, and the Mojave Grom 223S BLX 4x4 models—demonstrates how Fastrax has engineered these components with deep knowledge of the platform they're designed for. The four-piece configuration ensures that all four corners of your truck benefit from upgraded suspension, which is essential for achieving balanced handling characteristics. These shocks work in concert with your truck's existing geometry and drivetrain, whether you're running the brushed MEGA 380 motor found in the entry-level models or stepping up to the brushless 223S BLX platform. Build quality is paramount in RC components, and these aluminium shocks have been manufactured to withstand the punishment of regular use, including high-speed impacts, rough terrain, and the kind of aggressive driving that characterises weekend bashing sessions. The engineering focus is on durability without compromising the responsive feel that makes driving an RC truck enjoyable.

Frequently Asked Questions

• Which Arrma models does this shock set fit? — This Fastrax aluminium shock set is compatible with the Arrma 1/18 Granite Grom (MEGA 380 Brushed, available in Blue/Red, Green, and Red variants), the Arrma 1/16 Mojave Grom 223S BLX 4x4 (available with or without battery and charger in Black, White, and Teal colours), and the Arrma 1/16 Mojave Grom MEGA 380 Brushed 4x4. Whether you're running a brushed or brushless variant, this shock set has been engineered to work perfectly with your truck's suspension mounting points and geometry.
• Why should I upgrade my shocks from the factory components? — Factory plastic shocks are adequate for casual driving, but they're prone to flexing under load, which causes inconsistent damping and unpredictable handling. Aluminium shocks like this Fastrax set are significantly stiffer, maintain their geometry better during hard driving, and allow you to experiment with different shock oils and spring rates to fine-tune your truck's behaviour. The result is better handling precision, improved cornering performance, and a more connected, responsive driving experience—especially noticeable if you're pushing your truck hard or driving on technical terrain.
• Will this shock set improve my RC truck's performance on rough terrain? — Yes. Upgraded shocks improve bump compliance and suspension response, meaning your truck will handle rocky, bumpy, and uneven ground more predictably. The aluminium construction resists flex, so the shocks maintain consistent damping characteristics whether you're hitting small pebbles or larger obstacles, which translates to better traction and more predictable vehicle behaviour in challenging conditions.
• Can I tune the shocks after installation? — Absolutely. One of the main advantages of quality aftermarket shocks is that they open up tuning possibilities. You can experiment with different viscosity shock oils to change damping rates, adjust ride height using different spring preload settings, and fine-tune your truck's behaviour to match your driving style and local conditions. This makes these shocks an investment in the future enjoyment and performance of your RC truck.
• How difficult is it to install these shocks? — Installation is straightforward for anyone with basic RC car knowledge. The shocks are designed as direct replacements for the factory units, so you simply remove the old shocks and install the new ones using standard tools. No modifications, no custom work, and no special knowledge required—just about thirty minutes with basic hex wrenches and you'll be done.
• Is this set suitable for both brushed and brushless Arrma trucks? — Yes. These shocks are compatible with both brushed variants like the Granite Grom MEGA 380 and Mojave Grom MEGA 380, as well as the brushless Mojave Grom 223S BLX. The shock compatibility is determined by the truck's physical mounting points and suspension geometry, not by the motor type, so whether your truck has a brushed or brushless motor, this shock set will fit and perform equally well.
