Built from premium aluminium alloy, these front upper suspension arms are engineered to withstand the demands of aggressive driving whilst maintaining precise suspension geometry under load. The pair of arms provides balanced front-end handling characteristics, essential for maintaining traction and stability across varied terrain. For RC car enthusiasts in the UK looking to upgrade their Mojave Grom, these Fastrax components offer an affordable yet significant performance enhancement that will noticeably improve handling characteristics and extend the service life of your suspension system.

ARRMA Mojave Grom owners seeking to enhance their ready to run RC truck will find these aluminium front upper arms to be an excellent investment in reliability and performance. The upgrade from plastic to aluminium suspension arms is one of the most impactful modifications you can make to any small-scale desert truck, as it directly affects how your vehicle responds to inputs and maintains consistent geometry during high-energy driving sessions.

Key Features

• Aluminium Construction — These front upper arms are crafted from durable aluminium alloy rather than plastic, providing superior strength-to-weight ratio and exceptional resistance to bending or warping under aggressive driving conditions. Aluminium suspension components maintain their geometry more consistently over extended use compared to plastic alternatives, resulting in more predictable and responsive handling characteristics.
• Precision Engineering — Manufactured by Fastrax, a respected name in RC suspension upgrades, these arms are engineered to exact specifications matching OEM geometry requirements for the ARRMA Mojave Grom 1/16 scale platform. This precision ensures that the suspension geometry remains true and consistent, allowing your RC vehicle to perform at its potential without unwanted handling changes caused by component flex or deflection.
• Pair Configuration — This product includes both left and right front upper suspension arms, providing a complete front suspension upgrade solution. Rather than purchasing individual arms, getting a matched pair ensures symmetrical suspension geometry and balanced handling characteristics across both sides of your RC vehicle.
• Compatibility with Multiple Mojave Grom Variants — These front upper arms are compatible with a comprehensive range of ARRMA Mojave Grom variants, including the 1/16 Mojave Grom 223S BLX 4x4 DT models in various colour options (Teal, Black, and White), the Mojave Grom MEGA 380 brushed 4x4 small scale desert truck, and the 1/16 ARRMA Mojave Grom 4x4 RTA Race Kit. This broad compatibility makes these arms a practical upgrade choice regardless of which specific Mojave Grom model you own.
• Direct Drop-in Replacement — Installation is straightforward as these arms are designed as direct replacements for the factory plastic components on compatible models. No modifications or custom fabrication is required, making this a user-friendly upgrade suitable for owners of varying experience levels.
• Suspension System Enhancement — As part of the suspension tune-up category, these aluminium arms represent a critical component in optimising your vehicle's handling characteristics, ride quality and overall responsiveness across different driving conditions and terrain types.

Technical Performance

The Fastrax Arrma Mojave Aluminium Front Upper Arms represent a substantial upgrade in suspension system engineering. By transitioning from plastic to aluminium construction, you gain measurable improvements in chassis rigidity, suspension consistency and overall vehicle control. Aluminium is significantly stiffer than plastic whilst remaining lightweight, meaning your front suspension geometry will remain constant during cornering, acceleration and over bumps, rather than flexing slightly with each input as plastic components would. This translates directly to more predictable handling, improved traction delivery to the ground, and a vehicle that responds more precisely to your transmitter inputs. The material's inherent strength also means these arms will withstand the repeated stresses of aggressive driving, high-speed runs and rough terrain impacts far better than plastic alternatives, extending the service life of your entire suspension system. For builders of race kits or owners of ready to run RC Mojave Grom models looking to achieve competitive performance levels, upgrading to aluminium suspension components like these is considered a foundational modification. The engineering tolerances of these Fastrax components ensure perfect fit and function when installed on compatible ARRMA platforms, maintaining precise suspension geometry that directly influences how your RC truck performs in the field. These arms work in concert with your vehicle's shocks, anti-roll bars and geometry settings to create a balanced, responsive suspension system capable of handling demanding terrain and driving styles.

Frequently Asked Questions

• Are these aluminium front upper arms compatible with my ARRMA Mojave Grom? — Yes, these Fastrax FTAR075B front upper arms are specifically designed for multiple ARRMA Mojave Grom variants. Compatible models include the 1/16 Mojave Grom 223S BLX 4x4 DT (available in Teal, Black and White colour options), the Mojave Grom MEGA 380 brushed 4x4 small scale desert truck in both blue and red, and the 1/16 ARRMA Mojave Grom 4x4 RTA Race Kit. Check your specific model designation to confirm compatibility before ordering.
• What are the advantages of upgrading from plastic to aluminium suspension arms? — Aluminium suspension arms provide significantly greater rigidity and strength compared to standard plastic components, which means your suspension geometry remains precise and consistent even under aggressive driving or rough terrain. This enhanced stiffness translates to more predictable handling characteristics, improved traction, faster response to steering inputs, and a noticeably longer service life. Plastic components can flex subtly under load, causing handling inconsistencies, whereas these aluminium arms maintain their intended geometry throughout extended driving sessions, making them an excellent investment for anyone serious about RC performance.
• Is this a complete suspension upgrade solution? — This product includes only the front upper arms (a pair for left and right sides). Whilst this represents a significant suspension improvement, a complete front suspension upgrade would typically also include front lower arms, front hub carriers and potentially other components depending on your vehicle and desired performance level. However, upgrading the upper arms is an excellent starting point and delivers noticeable handling improvements on their own.
• How difficult is installation of these front upper arms? — Installation is relatively straightforward as these arms are direct replacements for the factory plastic components. No special modifications or fabrication is required. Basic RC tools and mechanical knowledge are typically sufficient for installation. If you're unfamiliar with suspension work, many RC hobby shops in the UK and online communities can provide installation guidance or support.
• Will these arms improve my lap times in competitive racing? — Yes, upgrading to aluminium suspension arms can improve consistency and handling precision, which often translates to faster, more predictable lap times, particularly on rough or technical tracks. The enhanced rigidity and maintained geometry provide a more stable platform for precise throttle and steering control, allowing you to drive with greater confidence and consistency.
• Are these arms suitable for beginners? — Absolutely. Whilst these are a performance-oriented upgrade, they are simple to install and require no special expertise to fit to your vehicle. Beginners will benefit from the improved handling consistency and increased durability, making them an excellent upgrade choice regardless of experience level.
