These precision-engineered suspension components are specifically designed to enhance the handling, durability and performance of your mini RC truck, whether you are a weekend basher enjoying outdoor terrain or a serious enthusiast looking to optimise your vehicle for competitive racing. Built from premium 7075-grade aluminium alloy, these rear lower arms offer a perfect balance between lightweight construction and exceptional rigidity, ensuring your Mini Maxx performs at its absolute best across varied driving conditions.

If you are searching for quality RC car parts UK retailers stock, look no further than this genuine Fastrax option part. The Mini Maxx platform has become increasingly popular among RC enthusiasts seeking a ready to run RC car that delivers genuine thrills in a compact, manageable package. Upgrading your suspension with these aluminium lower arms is one of the smartest performance investments you can make, as factory plastic arms can flex and wear over time, particularly if you regularly bash your RC vehicle or push it to its limits on challenging terrain.

This is a pair of rear lower arms, meaning you receive both left and right components needed for complete rear suspension replacement. Installation is straightforward for anyone with basic RC mechanical knowledge, and the upgrade process typically takes just a few minutes with standard hobby tools. Whether your Mini Maxx is brand new or has seen plenty of action, these Fastrax aluminium arms will improve responsiveness, stability and overall driving experience across grass, dirt, tarmac and mixed terrain.

Key Features

• 7075-Grade Aluminium Construction — These rear lower arms are manufactured from premium 7075 aluminium alloy, which is renowned in the aerospace and precision engineering industries for its exceptional strength-to-weight ratio. This material choice means you get significantly greater rigidity compared to standard plastic arms, resulting in more predictable handling, reduced flex during cornering, and improved overall chassis geometry consistency even under hard driving conditions.
• Pair Included — You receive both left and right rear lower arms in a single purchase, eliminating the need to buy two separate items and ensuring perfect matching between sides. This symmetrical design is crucial for balanced suspension performance and predictable handling characteristics across both sides of your RC vehicle.
• Direct Compatibility with Traxxas Mini Maxx BL-2S — These arms are specifically engineered to fit the Traxxas Mini Maxx BL-2S in all colour variants including green, blue, black and orange models. This perfect fitment ensures no modification is required and you can achieve immediate performance gains without compromise or adjustment issues.
• Lightweight Performance Design — Despite being significantly stronger than plastic alternatives, aluminium construction keeps overall weight minimal, preserving the Mini Maxx's excellent power-to-weight ratio and responsiveness. Lower unsprung weight in the suspension contributes to improved ride quality and more precise control inputs.
• Precision Engineered Geometry — The arm geometry is carefully calculated to maintain factory suspension angles and characteristics while providing superior durability. This means you upgrade to aluminium strength without altering the handling characteristics you have come to know and enjoy.
• Genuine Fastrax Quality — Fastrax is a recognised and respected manufacturer of RC option parts throughout the UK and Europe. Their components are engineered to original specifications and manufactured to exacting quality standards, ensuring every part performs exactly as intended.

Technical Performance

The rear lower suspension arms are fundamental to your RC car's handling dynamics, and upgrading from plastic to premium aluminium represents one of the most cost-effective performance improvements available. During aggressive cornering, braking and acceleration, plastic arms can flex and twist, causing the suspension geometry to deviate from manufacturer specifications. This flex translates directly to unpredictable handling, inconsistent steering response and premature wear on suspension components. By switching to 7075 aluminium, you eliminate this flex entirely, maintaining rock-solid suspension geometry regardless of driving intensity. The engineering behind these Fastrax components ensures they deliver enhanced steering response, improved cornering grip, and greater stability on technical terrain. The material's inherent damping characteristics also contribute to improved ride quality, absorbing vibration more effectively than plastic while maintaining precise control feel. These arms are manufactured to exacting tolerances, ensuring perfect fitment and alignment with other suspension components. Whether you are driving on loose gravel, groomed dirt tracks, grass fields or concrete surfaces, these arms will maintain their shape and performance characteristics, whereas plastic components may fatigue and crack over extended use. For anyone serious about RC car performance in the UK market, this represents genuine engineering quality at an accessible price point.

Frequently Asked Questions

• Are these compatible with my Traxxas Mini Maxx BL-2S? — Yes, these Fastrax rear lower arms are specifically designed for the Traxxas Mini Maxx BL-2S and are compatible with all colour variants including the green, blue, black and orange models. They are a direct bolt-on replacement for the factory plastic arms with no modification required.
• What is the advantage of aluminium over plastic arms? — Aluminium offers significantly greater rigidity and durability compared to plastic. Plastic arms flex during aggressive driving, which causes suspension geometry to shift and handling to become unpredictable. Aluminium maintains strict geometry consistency, improving steering response, cornering grip and overall stability. Additionally, aluminium resists cracking and fatigue that can occur in plastic components after extended use, making these arms a long-term investment in reliability.
• Will upgrading to aluminium arms change how my RC car handles? — These arms are engineered to maintain the original factory suspension geometry and angles, so you will not experience unexpected handling changes. What you will notice is improved precision, more responsive steering inputs, and more consistent performance across all driving conditions. The Mini Maxx will feel more planted and controllable, particularly during fast cornering and aggressive driving.
• Can I install these myself? — Yes, replacing the rear lower arms is straightforward and requires only basic RC mechanical knowledge and standard hobby tools such as a hex wrench set. The original arms simply unscrew from the rear hub carriers and upper chassis rail, and these Fastrax components bolt directly in place. Most users can complete the installation in just a few minutes. If you are unfamiliar with RC car maintenance, RC Model Shop's team of experienced enthusiasts are happy to provide guidance.
• Are these suitable for beginners? — Absolutely. These arms are an excellent upgrade for beginner and intermediate RC drivers who own a Mini Maxx and want to improve reliability and handling without adding complexity. Installation is simple enough for newcomers to tackle, and the performance improvement is immediately noticeable. Many beginners find that upgrading suspension components like these significantly improves their driving experience and enjoyment.
• What makes Fastrax a trusted brand? — Fastrax is a recognised manufacturer of RC option parts used and recommended by enthusiasts throughout the UK and Europe. Their components are engineered to match or exceed original specifications and are manufactured to consistent quality standards. They offer genuine upgrades rather than cheap copies, meaning you are investing in reliability and performance.
• How long do these aluminium arms last? — With proper care, 7075 aluminium arms will outlast multiple sets of plastic components. They are resistant to cracking, fatigue and degradation, and will maintain their strength and geometry for years of regular use. Many RC enthusiasts find that aluminium suspension components are a one-time upgrade that they never need to replace.
