Fastrax Mini Maxx 7075 Aluminium Rear Upper Arm Set Pair FTTX508G

Overview

The Fastrax Mini Maxx 7075 Aluminium Rear Upper Arm Set (pr) FTTX508G is a premium suspension upgrade component designed specifically for the Traxxas Mini Maxx BL-2S brushless RC truck. This pair of high-quality aluminium arms represents a significant performance enhancement over the standard plastic components, offering improved durability, precision and reliability for serious RC enthusiasts in the UK. Whether you're running an RC car for weekend bashing, competitive racing or regular trail use, upgrading to aluminium suspension components is one of the most effective ways to improve handling characteristics and extend the lifespan of your vehicle.

Fastrax is a renowned manufacturer of professional-grade RC spares and upgrade parts, trusted by RC hobbyists and competitors worldwide. The Mini Maxx 7075 range specifically targets the Traxxas Mini Maxx platform, providing drop-in replacement parts that maintain factory fitment whilst delivering genuine performance and durability improvements. This rear upper arm set is manufactured from aerospace-grade 7075 aluminium alloy, which is significantly stronger and more rigid than plastic alternatives, making it the perfect choice for anyone looking to build a more responsive and durable ready to run RC truck.

Available in the UK through RC Model Shop, this suspension upgrade is an excellent investment for Mini Maxx owners who want to maximise their RC car's potential. The combination of lightweight construction and exceptional strength makes this arm set ideal for aggressive driving conditions, rough terrain and high-speed bashing sessions where standard plastic components might flex or break.

Key Features

• 7075 Aluminium Alloy Construction — These rear upper arms are crafted from premium 7075 aluminium, which is the same material specification used in aerospace and high-performance engineering applications. This material offers superior strength-to-weight ratio compared to plastic arms, meaning better suspension geometry maintenance during aggressive driving and jumps whilst keeping overall vehicle weight minimal.
• Pair Included — The set includes both left and right rear upper arms, providing a complete upgrade for the rear suspension geometry of your Traxxas Mini Maxx. This pair configuration ensures perfectly matched components that work together to deliver consistent handling characteristics across both sides of the vehicle.
• Direct Replacement Design — These arms are engineered as drop-in replacements for the standard Mini Maxx suspension components, requiring no modification to your RC truck. This means installation is straightforward and returns your vehicle to running condition quickly, without needing to adjust geometry or mounting points.
• Enhanced Rigidity and Precision — Aluminium components provide significantly greater rigidity than plastic arms, which means less flex under load and more predictable handling dynamics. This translates to improved steering response, better cornering control and more consistent lap times whether you're racing or bashing on UK trails.
• Improved Durability in Demanding Conditions — Whether you're running your RC car on rocky terrain, through water crossings or over rough ground, aluminium arms resist impact damage far better than their plastic counterparts. This durability advantage means fewer broken suspension components and longer time between rebuilds.
• Perfect for Traxxas Mini Maxx BL-2S Models — This set is specifically engineered for compatibility with all colour variants of the Traxxas Mini Maxx BL-2S, including black, orange, green and blue models. Fastrax ensures perfect fitment and alignment with these vehicles.

Technical Performance

The Fastrax Mini Maxx 7075 Aluminium Rear Upper Arm Set represents a significant step up in suspension component quality and engineering. Built from genuine 7075-T6 aluminium alloy, these arms deliver the kind of precision and durability demanded by serious RC enthusiasts who run their vehicles regularly in challenging conditions across the UK. The material selection is crucial to performance: 7075 aluminium is harder and more rigid than standard 6061 aluminium, whilst remaining lighter than steel alternatives. This means suspension geometry is maintained more accurately during cornering, braking and acceleration phases, translating directly to improved handling predictability and driver control. The arms are precision-manufactured to exact tolerances, ensuring that both left and right components are identically matched for balanced handling characteristics. When installed as a pair on the rear suspension of your Mini Maxx, these arms work in conjunction with the vehicle's shock absorbers and other suspension components to provide a more responsive, controlled driving experience. The rigidity advantage of aluminium also means reduced flex during weight transfer, which is particularly important during high-speed cornering or aggressive off-road driving where suspension compliance can negatively impact stability. For RC car owners in the UK running 2S LiPo-powered brushless systems like the Mini Maxx BL-2S, the combination of brushless motor performance and upgraded aluminium suspension components creates a significantly more capable vehicle platform.

Frequently Asked Questions

• Will aluminium arms improve my Mini Maxx RC truck's handling? — Yes, significantly. Aluminium arms are much more rigid than the plastic components used in standard Mini Maxx builds. This rigidity reduces flex during cornering and acceleration, which means the suspension geometry stays more consistent and delivers more predictable handling. You'll notice sharper steering response, better control in fast corners and more confidence when pushing the vehicle hard on challenging terrain across the UK.
• Are these Fastrax arms a direct fit for my Traxxas Mini Maxx? — Yes, these are engineered as direct drop-in replacements for the standard plastic upper arms on the Traxxas Mini Maxx BL-2S. No drilling, modification or geometry adjustment is required. Simply remove the stock plastic arms and install these aluminium arms in their place. The mounting points are identical to the OEM components.
• What makes 7075 aluminium better than plastic or other metals? — 7075 aluminium offers an optimal balance of strength, weight and rigidity. It's significantly stronger than plastic (which can crack or flex under load) whilst being much lighter than steel. The material is used in aerospace applications, meaning it's engineered for precision and reliability. For RC trucks, this translates to suspension arms that maintain their shape under stress, delivering consistent performance lap after lap.
• Will these arms fit other Traxxas models? — No, these arms are specifically engineered for the Traxxas Mini Maxx platform and are not compatible with other Traxxas models. The Mini Maxx has unique suspension geometry and mounting configuration. However, Fastrax manufactures 7075 aluminium upgrade parts for many other Traxxas models, so you may find compatible options for other vehicles in their product range.
• How do I install these rear upper arms? — Installation is straightforward: simply unbolt the existing plastic upper arms from your Mini Maxx and replace them with these aluminium components. Use the existing hardware (bolts and bearings) from your standard arms. The process typically takes 5-10 minutes per arm and requires no special tools beyond a hex wrench set.
• Will I need to adjust my RC truck's geometry after fitting these arms? — No, these arms maintain the same geometry as the OEM plastic components, so no camber, toe or caster adjustment is needed. They are true drop-in replacements. Your Mini Maxx will be ready to run immediately after installation.
• Are these suitable for beginners? — Absolutely. Whilst these are premium upgrade components, they're suitable for RC drivers of any skill level. Even beginners will benefit from the improved durability and handling characteristics. Installation is simple enough for newcomers, and there's no complex setup required.
• What's the difference between these and the plastic stock arms? — The primary differences are material (7075 aluminium versus plastic), rigidity (aluminium is significantly stiffer and resists flex), durability (aluminium won't crack or break as easily), and precision (aluminium maintains tighter tolerances). These lead to measurably better handling, longer lifespan, and more predictable performance during driving sessions.
