Fastrax Arrma Mojave Aluminium Front Upper Arms Pair FTAR075BK

Overview

The Fastrax Arrma Mojave Aluminium Front Upper Arms (PR) FTAR075BK are a premium suspension upgrade designed specifically for the Arrma 1/16 Mojave Grom family of RC vehicles. These replacement front upper arms are precision-engineered from high-quality aluminium to provide enhanced durability, improved handling characteristics and superior longevity compared to the standard plastic components. Whether you're an experienced RC enthusiast looking to fine-tune your Mojave Grom's suspension geometry or a dedicated basher seeking to reinforce your vehicle's front end for more aggressive driving, these aluminium upper arms represent a worthwhile investment in performance and reliability.

As a popular small-scale desert truck, the Arrma Mojave Grom has earned a strong reputation in the RC car UK market for delivering authentic off-road performance in a manageable 1/16 scale format. Upgrading to aluminium suspension components like these Fastrax arms is one of the most effective ways to extend your vehicle's lifespan and maintain consistent handling across extended driving sessions. The supplied pair of front upper arms will directly replace the OEM plastic versions, making installation straightforward for owners familiar with basic RC suspension work.

Fastrax is a recognised manufacturer of precision RC upgrade parts and accessories, known for producing components that strike an excellent balance between affordability and performance. The use of aluminium in these front upper arms means they offer significantly greater resistance to bending, cracking and fatigue compared to plastic alternatives, whilst remaining lightweight enough not to negatively impact your Mojave Grom's acceleration or handling dynamics.

Key Features

• Aluminium Construction — Manufactured from premium-grade aluminium alloy, these upper arms are considerably more durable and resistant to impact damage than the standard plastic components supplied with the vehicle, ensuring they will withstand repeated bashing and competitive racing without deforming or breaking.
• Direct OEM Replacement — These arms are engineered as a direct replacement for the front upper suspension arms on compatible Arrma Mojave Grom models, meaning they will bolt straight on without requiring any modifications to your vehicle's chassis or suspension geometry.
• Supplied as a Pair — The package includes both left and right front upper arms, so you have everything needed to complete a full front suspension upgrade in one purchase, eliminating the need to source components from multiple suppliers.
• Enhanced Suspension Geometry Control — The rigid aluminium construction helps maintain precise suspension geometry during hard cornering, acceleration and braking, which translates to more predictable handling and improved driving control during competitive racing or recreational driving.
• Longevity and Value — Upgrading to aluminium arms early in your vehicle's life can help prevent costly suspension damage repairs and reduce the frequency of component replacement, providing excellent long-term value for regular RC car enthusiasts in the UK.
• Compatible with Multiple Mojave Grom Variants — These arms are designed to fit the full range of 1/16 Mojave Grom models including the 223S BLX in multiple colour options and the Mega 380 brushed versions, making them a versatile choice for Arrma fans.

Technical Performance

The Fastrax Arrma Mojave Aluminium Front Upper Arms are engineered with precision and attention to detail that reflects Fastrax's commitment to delivering quality upgrade components. The aluminium material selection is critical to the performance profile of these arms—aluminium offers a superior strength-to-weight ratio compared to the plastic alternatives, meaning you gain durability without adding significant mass that could affect your Mojave Grom's acceleration characteristics. The arms are manufactured to exacting tolerances to ensure that they maintain the correct suspension geometry and ride height, which is essential for consistent handling performance on a small-scale 1/16 vehicle where every millimetre of suspension alignment makes a measurable difference to cornering speed and stability. The rigid construction significantly reduces the flex and deflection that occurs in plastic arms under load, particularly important during aggressive cornering or when landing jumps. For owners running their Mojave Grom regularly—whether on dirt tracks, outdoor terrain or carpet surfaces—these aluminium arms will dramatically extend the lifespan of your front suspension and reduce the likelihood of catastrophic failure during important races or casual weekend driving sessions.

Frequently Asked Questions

• Are these aluminium front upper arms compatible with all Arrma Mojave Grom models? — These Fastrax arms are designed to fit the following Arrma 1/16 Mojave Grom variants: the 223S BLX 4x4 Desert Truck in White, Black and Teal colours (models C-ARA2304ST2, C-ARA2304T1 and C-ARA2304ST1), the Mojave Grom Mega 380 Brushed 4x4 in Red and Blue (models C-ARA2104T1 and C-ARA2104T2), and the 1/16 Arrma Mojave Grom 4x4 RTA Race Kit (model C-ARA2104KT1). If you own any of these models, these arms will fit correctly without modification.
• Why should I upgrade from the standard plastic arms to aluminium? — The plastic upper arms that come standard on the Mojave Grom will flex under load, particularly during aggressive cornering or landing jumps, which can cause inconsistent suspension geometry and unpredictable handling. Aluminium arms are significantly stiffer and more resistant to bending and impact damage, which means your suspension will maintain its intended geometry throughout your driving session, providing more consistent handling and better turning performance. Additionally, aluminium arms will last considerably longer than plastic before requiring replacement, reducing your long-term maintenance costs.
• Will these aluminium arms improve my lap times in racing? — By maintaining more consistent suspension geometry and reducing flex, these aluminium arms can help you achieve more predictable and faster cornering performance, particularly valuable if you're competing in organised RC racing events. The improved suspension rigidity allows you to push your Mojave Grom harder into corners with greater confidence that the handling will remain consistent. Many serious RC racers in the UK consider aluminium suspension upgrades an essential component of their race setup.
• How difficult is it to install these front upper arms? — Installation is straightforward for anyone with basic RC maintenance experience. You will need to remove the old plastic arms by unbolting them from the suspension pivot points, then bolt the new aluminium arms into place using the same fastening points. The process typically takes less than 15 minutes per arm. Basic RC tools such as hex drivers and screwdrivers are required, but no specialised equipment is necessary.
• What is the warranty on these Fastrax arms? — The arms are subject to standard manufacturer's warranty for defects in materials and workmanship. Damage caused by impact, abuse or normal wear and tear is not covered by warranty, as these are consumable suspension components expected to be replaced periodically depending on usage intensity.
