Fastrax Arrma Granite Grom 1/18 Aluminium Front Upper Arms Pair FTAR050B

Overview

The Fastrax Arrma Grom/Granite Aluminium Front Upper Arms (PR) represent a genuine upgrade for owners of the popular Arrma 1/18 Granite Grom monster truck. These precision-engineered suspension components are crafted from high-quality aluminium, making them significantly more durable than the standard plastic alternatives supplied with your RC car. Whether you're a committed hobbyist running your Granite Grom through demanding bash sessions or a more serious RC enthusiast looking to improve your vehicle's handling and reliability, these front upper arms deliver tangible performance benefits that justify the investment.

In the UK RC hobby community, upgrading suspension components like upper arms is one of the most popular and effective ways to enhance both the durability and handling characteristics of your monster truck. The move from plastic to aluminium is particularly important on the front suspension, where these arms experience constant stress during jumps, landings, and cornering. By choosing Fastrax aluminium upper arms for your Granite Grom, you're making a smart decision that will extend your vehicle's lifespan, reduce maintenance requirements, and improve your driving experience on any terrain.

RC Model Shop stocks this genuine Fastrax component as part of our comprehensive range of suspension upgrades and tuning parts for the Arrma range. These upper arms are engineered to the exact specifications required by Arrma vehicles, ensuring perfect fitment and compatibility without any modification or adjustment needed.

Key Features

• Aluminium construction — These upper arms are manufactured from durable aluminium rather than plastic, providing superior strength and rigidity under the intense forces generated during aggressive driving, jumps, and collisions.
• Precision engineering — Fastrax components are manufactured to strict tolerances that match OEM specifications, ensuring perfect fitment and eliminating any play or wobbling in your suspension geometry.
• Pair included — You receive both left and right front upper arms in this package, allowing you to upgrade both sides of your Granite Grom's front suspension in one purchase.
• Direct compatibility — These upper arms are specifically designed for the Arrma 1/18 Granite Grom range and require no modification or adjustment to install, making them ideal for upgrading your existing vehicle.
• Extended durability — Aluminium's superior material properties mean these arms will withstand repeated impacts, vibration, and stress far better than plastic alternatives, reducing the frequency of breakages and repairs.
• Improved handling geometry — By replacing worn or flexing plastic arms with rigid aluminium components, you'll notice improved steering response, better cornering consistency, and more predictable vehicle behaviour.
• Cost-effective upgrade — At under £9, these suspension components represent outstanding value for money when considering the durability and performance improvements they deliver to your RC monster truck.

Technical Performance

The Fastrax Arrma Grom/Granite Aluminium Front Upper Arms are engineered with precision manufacturing standards that ensure they maintain the exact suspension geometry specified by Arrma for optimal vehicle performance. These components are manufactured from high-grade aluminium, a material chosen specifically for its superior strength-to-weight ratio compared to the standard plastic upper arms. The aluminium construction provides exceptional rigidity under load whilst remaining lightweight enough to preserve your vehicle's handling balance and suspension response characteristics. The arms feature precision-drilled mounting points that align perfectly with your Granite Grom's chassis, ensuring zero play or misalignment issues that could affect steering accuracy or suspension performance. These front upper arms work in conjunction with your vehicle's steering system and shock absorbers to maintain consistent geometry during aggressive driving, jumps, and high-speed cornering. The material's inherent durability means you'll experience fewer breakages and reduced downtime for repairs, allowing you to spend more time enjoying your RC car and less time in the workshop. For owners of the Arrma Granite Grom who take their bashing seriously, upgrading to aluminium suspension components is one of the single most effective ways to improve both performance and reliability.

Frequently Asked Questions

• Are these aluminium upper arms compatible with my Arrma Granite Grom? — Yes, these Fastrax components are specifically engineered for the Arrma 1/18 Granite Grom range. They are compatible with the C-ARA2102T2, C-ARA2102T1, and C-ARA2102T3 Granite Grom models in all colour variants. Simply remove your existing plastic upper arms and install these aluminium replacements—no modification required.
• Why should I upgrade from plastic to aluminium upper arms? — Aluminium upper arms offer several significant advantages over plastic. They are substantially more durable and resistant to impact damage, maintain their shape under stress (preventing geometry changes that affect handling), last considerably longer before requiring replacement, and provide a noticeably more rigid and responsive feel during driving. For serious bashers and anyone who drives their Granite Grom frequently, the durability upgrade justifies the modest investment.
• Will these improve my RC car's handling? — Yes, upgrading to aluminium upper arms will improve your vehicle's handling characteristics. Plastic arms can flex under acceleration, braking, and cornering loads, which compromises steering accuracy and suspension geometry. Rigid aluminium arms maintain precise suspension geometry in all driving conditions, resulting in sharper steering response, more consistent cornering, and better overall driving feel.
• Are these difficult to install? — No, installation is straightforward. These upper arms are designed to bolt directly onto your Granite Grom without any modification. Simply unbolt your existing plastic upper arms and install the aluminium replacements using the same mounting points. Installation typically takes just a few minutes with basic RC tools.
• Do I need to replace both arms at the same time? — Whilst you can replace just one arm if needed, we recommend upgrading both the left and right upper arms as a pair. This package conveniently includes both components, and replacing both ensures consistent handling and symmetrical suspension geometry across your vehicle.
