Technical Performance
The Fastrax Losi Micro-B Aluminium Rear Arm Mount represents the kind of engineering refinement that serious RC competitors expect. By replacing the factory plastic rear arm mount with this precision-engineered aluminium assembly, you gain measurable improvements in chassis rigidity and suspension response. The aluminium construction resists flex and deformation under cornering loads and impact events far more effectively than plastic, meaning your suspension geometry remains consistent throughout aggressive driving. This consistency translates directly into more predictable handling, improved traction control, and the confidence to push harder through technical sections of a track. The two-piece design allows for height adjustment and fine-tuning, enabling drivers to optimise their suspension setup for specific track conditions or driving preferences. Whether you're running a competition setup on a UK racing circuit or enjoying casual bashing, this upgrade delivers noticeable performance gains. The material choice also provides superior thermal stability, meaning the component performs consistently across varying ambient temperatures and extended driving sessions. For drivers committed to maximising their Losi Micro-B platform, this rear arm mount is a logical and effective upgrade that forms part of a complete performance enhancement strategy alongside suspension arms, shock towers, and other Fastrax Micro-B components.

Frequently Asked Questions
- Is the Fastrax Losi Micro-B Aluminium Rear Arm Mount a worthwhile upgrade for my Micro-B? — Absolutely. Upgrading from the factory plastic rear arm mount to this precision-engineered aluminium assembly delivers noticeable improvements in chassis rigidity, suspension consistency, and overall durability. If you're running your Micro-B competitively or driving aggressively, this upgrade will improve handling predictability and reduce component wear over time. The enhanced durability also means fewer replacement parts and longer service life between rebuilds.
- Will this rear arm mount fit my Losi Micro-B without modification? — Yes, this component is engineered specifically for the Losi Micro-B platform and guarantees perfect fitment. No drilling, cutting, or modification of any kind is required. Installation is straightforward and can be completed in minutes using standard tools.
- What is the difference between this aluminium rear arm mount and the factory plastic version? — The primary difference is material construction. The factory plastic mount flexes under load, which can compromise suspension geometry and handling consistency. This aluminium upgrade provides superior rigidity, preventing flex and maintaining precise suspension alignment throughout driving sessions. Aluminium also resists impact damage far better than plastic, delivering improved durability and a longer service life. The two-piece design also allows for height adjustment and fine-tuning capabilities not available with the original part.
- Can I use this with other Fastrax Micro-B upgrades? — Yes, this rear arm mount is fully compatible with the complete range of Fastrax Losi Micro-B upgrade components, including the aluminium front arm mount, shock towers, suspension arms, hub carriers, and all other aftermarket parts. Many competitors build complete upgraded Micro-B platforms by combining multiple Fastrax components for optimal performance.
- Is this suitable for beginners? — While this is primarily an upgrade component best suited to drivers already familiar with their Micro-B platform, installation is very straightforward and requires only basic RC knowledge. However, beginners would benefit from understanding suspension setup and geometry before upgrading to performance components. Once installed, this mount will improve handling predictability, which can actually benefit drivers at all skill levels.
- How does this upgrade affect my Micro-B's performance? — The primary performance improvements are in handling consistency and suspension response. By eliminating plastic flex, your suspension geometry remains precise and predictable throughout driving sessions. This translates into better traction control, more responsive steering input, and improved cornering stability. You'll notice reduced tramlining, better bump compliance, and the confidence to drive harder through technical sections.
