Overview

The Fastrax Mini Maxx 7075 Aluminium Rear Upper Arm Set represents a premium upgrade option for owners of the Traxxas Mini Maxx BL-2S brushless RC truck. Crafted from high-grade 7075 aluminium, these rear upper arms deliver exceptional strength and rigidity while maintaining minimal weight, making them an ideal choice for RC enthusiasts in the UK looking to enhance their vehicle's performance and durability. Whether you're a seasoned RC basher, a weekend racer, or someone discovering the world of ready-to-run RC cars for the first time, this suspension upgrade offers tangible improvements over the stock plastic components that come standard on your Mini Maxx.

Suspension geometry and arm integrity are critical factors in RC vehicle performance, affecting everything from handling precision to durability during aggressive driving. By upgrading to these aluminium rear upper arms, you gain not only superior structural rigidity but also the confidence that comes with knowing your suspension components can handle demanding terrain and high-speed impacts. The Mini Maxx platform has proven itself as a capable and fun 1/10 scale truck, and this Fastrax upgrade ensures your vehicle maintains its performance edge even after extended use and aggressive play.

RC Model Shop stocks this essential suspension upgrade as part of our comprehensive range of Fastrax spares and tune-up options for the Traxxas Mini Maxx BL-2S.

Key Features

• 7075 Aluminium Construction — These rear upper arms are manufactured from premium 7075 aluminium alloy, which is recognised in the RC industry as the gold standard for suspension components due to its exceptional strength-to-weight ratio, allowing you to upgrade your Mini Maxx without adding unnecessary mass that would compromise acceleration and handling.
• Pair Set Included — This product includes a matched pair of rear upper arms, meaning you receive both the left and right components needed to complete your rear suspension upgrade in a single purchase, ensuring symmetrical geometry and balanced vehicle behaviour.
• Direct Traxxas Mini Maxx Compatibility — These arms are specifically engineered to fit the Traxxas Mini Maxx BL-2S in all colour variants including black, orange, green and blue, providing a perfect drop-in replacement for the factory plastic arms and eliminating any fitment concerns or modification requirements.
• Enhanced Durability — Aluminium arms are significantly more resistant to bending, cracking and damage compared to plastic factory arms, extending the service life of your suspension and reducing the frequency of replacement parts you'll need to purchase for your RC car UK setup.
• Improved Suspension Response — The increased rigidity of aluminium components compared to plastic delivers more consistent and predictable suspension performance across varied terrain, improving cornering stability and jump landing control during high-speed driving sessions.
• Professional-Grade Upgrade — This is a genuine Fastrax OEM component rather than a generic aftermarket part, meaning it meets the same quality standards and precision tolerances as original Traxxas suspension arms, ensuring long-term reliability.

Technical Performance

The Fastrax Mini Maxx 7075 Aluminium Rear Upper Arm Set represents a significant engineering upgrade over the standard plastic suspension arms that ship with the Traxxas Mini Maxx BL-2S brushless RC truck. The use of 7075 aluminium alloy is particularly significant because this material is substantially harder and more rigid than the plastic alternatives, yet maintains excellent machinability and precision fit. The suspension geometry of a 1/10 scale RC truck depends critically on arm rigidity; when arms flex or bend under load, they alter the camber angle and suspension geometry, causing inconsistent handling and unpredictable vehicle behaviour. By upgrading to these aluminium arms, you eliminate deflection under aggressive cornering and jumping, maintaining precise suspension geometry throughout your driving session. The material selection also provides superior impact resistance, meaning your suspension will better withstand the inevitable crashes and hard landings that characterise off-road RC bashing. The engineering precision of Fastrax components ensures that these arms will integrate seamlessly with your existing Mini Maxx BL-2S suspension setup, maintaining factory specifications for mounting points, bearing locations and overall geometry. This is particularly important for owners of the brushless 2S LiPo-powered Mini Maxx variants, which deliver higher power outputs than many competing toy-grade RC vehicles, making durable suspension components essential for reliability and performance.

Frequently Asked Questions

• Will these aluminium rear upper arms fit my Traxxas Mini Maxx BL-2S? — Yes, these arms are specifically designed as direct replacement components for the Traxxas Mini Maxx BL-2S and are compatible with all colour variants of this model, including the black, orange, green and blue versions. They install in place of the factory plastic arms without any modification or additional components required.
• What is the advantage of upgrading to aluminium arms compared to keeping the stock plastic arms? — Aluminium arms offer significantly greater rigidity, which means they maintain consistent suspension geometry under cornering loads and impacts, resulting in more predictable handling and improved durability. Plastic arms flex and bend under the forces generated by the brushless 2S LiPo motor of the Mini Maxx, whereas aluminium arms maintain their shape, improving overall vehicle control and reducing the need for frequent arm replacement.
• Are these genuine Fastrax parts or aftermarket copies? — These are genuine original equipment manufacturer (OEM) Fastrax components, manufactured to the same specifications and quality standards as official Traxxas suspension upgrades. Fastrax is the recognised brand for Mini Maxx upgrade parts, and purchasing genuine components ensures compatibility, reliability and warranty protection.
• Do I need any special tools or expertise to install these rear upper arms? — Installation requires basic RC maintenance knowledge and standard hex wrenches and screwdrivers, tools that any RC hobby enthusiast should have in their toolkit. The installation process follows standard suspension arm replacement procedures and does not require specialist equipment or extensive technical knowledge, making this an ideal upgrade for intermediate RC car UK owners.
• Will upgrading to these arms improve my Mini Maxx's speed? — While these arms don't directly increase motor output or top speed, they do improve suspension responsiveness and geometry consistency, which can translate to better acceleration out of corners and more efficient power delivery to the ground, subtly improving overall lap times and handling performance during racing or timed courses.
• How durable are these aluminium arms compared to the plastic factory arms? — 7075 aluminium is significantly more durable than the plastic used in factory Mini Maxx arms, offering superior resistance to cracking, bending and fracturing from impacts and hard landings. Most users report that aluminium suspension arms last several times longer than plastic equivalents when subjected to the same driving abuse, making them a cost-effective upgrade over the long term.
