Overview
The Fastrax Losi Micro-B Aluminium Front Caster Block is a premium upgrade component designed for the Losi 1/24 Micro-B 2WD Buggy and 1/28 Micro-T 2WD Stadium Truck platforms. This precision-engineered pair of caster blocks represents a significant performance enhancement for RC enthusiasts in the UK looking to improve their micro-scale RC car handling and durability. Whether you are a seasoned RC car UK competitor or a weekend basher who demands reliability from every upgrade, this Fastrax component delivers the strength and precision engineering you need to take your Losi micro-scale buggy or truck to the next level.
Manufactured by Fastrax, a recognised brand for quality RC car upgrades and accessories, these front caster blocks are constructed from high-grade aluminium alloy, offering a perfect balance between lightweight performance and exceptional durability. The move from standard plastic components to full aluminium construction significantly improves the structural integrity of the front suspension geometry, ensuring consistent handling characteristics even after hundreds of hours of hard driving. This is especially important for micro-scale RC cars like the Losi Micro-B and Micro-T, where precision suspension geometry directly translates to competitive lap times and predictable cornering behaviour.
If you are looking to upgrade your ready to run RC buggy or stadium truck with components that offer real performance benefits, the Fastrax Losi Micro-B Aluminium Front Caster Block is an essential modification. These caster blocks maintain the original mounting points and compatibility whilst providing superior rigidity, better load distribution, and longer service life compared to the standard plastic versions. For RC enthusiasts across the UK who want to extend the lifespan of their Losi micro-scale vehicles and improve overall handling precision, this upgrade is a worthwhile investment.
Key Features
- Aluminium Construction — The caster blocks are manufactured from lightweight yet durable aluminium alloy rather than plastic, providing superior rigidity and structural integrity that resists flex and deformation during aggressive cornering and high-speed driving.
- Direct OEM Compatibility — These components are engineered to fit seamlessly onto Losi Micro-B and Losi Micro-T vehicles without modification, maintaining exact factory suspension geometry and mounting positions for hassle-free installation.
- Pair Configuration — This kit includes both front caster blocks (left and right), providing a complete front suspension upgrade in a single purchase rather than requiring separate orders.
- Enhanced Durability — Aluminium construction offers significantly improved longevity compared to plastic caster blocks, reducing the need for frequent replacement and providing better value over the lifetime of your RC car UK investment.
- Precision Engineering — Fastrax components are manufactured to tight tolerances, ensuring perfect fitment and consistent performance across multiple vehicles and multiple seasons of use.
- Performance Tuning Advantage — The improved rigidity of aluminium caster blocks can result in more predictable handling characteristics, better steering response, and more consistent lap times for competitive drivers.
Technical Performance
The Fastrax Losi Micro-B Aluminium Front Caster Block represents a meaningful engineering upgrade for micro-scale RC suspension systems. Constructed entirely from aircraft-grade aluminium alloy, these caster blocks are designed to replace the standard plastic factory components whilst maintaining 100% compatibility with the existing suspension architecture. The aluminium material choice is critical for performance—whilst slightly heavier than plastic, the improved rigidity eliminates flex and deflection that occurs under cornering loads, resulting in more consistent caster angles and better steering response. For the 1/24 scale Losi Micro-B 2WD Buggy and 1/28 scale Losi Micro-T 2WD Stadium Truck platforms, this translates to improved turn-in sharpness, more predictable mid-corner stability, and enhanced acceleration traction. The caster geometry—the angle of the steering knuckle relative to vertical—is critical for suspension performance, and the rigid aluminium construction ensures this geometry remains consistent throughout a race or driving session. For RC enthusiasts competing in micro-scale racing or weekend recreational bashing, these upgraded caster blocks are a proven performance modification that delivers tangible improvements in handling precision and vehicle longevity. Installation is straightforward for anyone with basic RC car maintenance skills, requiring only standard hex wrenches and a small amount of time. The pair configuration ensures both sides of the vehicle receive identical upgrades, maintaining perfect left-to-right symmetry essential for balanced handling.

Frequently Asked Questions
- Which Losi vehicles are compatible with these front caster blocks? — These aluminium caster blocks are designed specifically for the Losi 1/24 Micro-B 2WD Buggy (available in White and Silver versions) and the Losi 1/28 Micro-T 2WD Stadium Truck (also available in White and Silver). If you own either of these micro-scale ready to run RC vehicles, these upgrades are an ideal fit.
- Will these aluminium caster blocks improve my lap times? — Yes, upgrading to aluminium caster blocks from the standard plastic versions can improve handling consistency and predictability, which many competitive drivers translate into faster, more repeatable lap times. The improved rigidity ensures suspension geometry remains stable under braking, acceleration, and cornering loads, giving you confidence to push harder through tight corners.
- Are these caster blocks suitable for beginners to install? — Yes, installation is very straightforward for anyone with basic RC car maintenance experience and a small set of hex wrenches. The components bolt directly onto your existing suspension geometry without any modification or special tools required. If you have upgraded components on other RC cars before, you will find this installation process simple and quick.
- What is the difference between these Fastrax aluminium blocks and the original plastic version? — The primary difference is material construction—Fastrax uses precision-engineered aluminium alloy whilst Losi OEM caster blocks are plastic. Aluminium offers superior rigidity (eliminating flex under load), increased durability (longer service life before replacement is needed), and improved suspension geometry consistency. For competitive drivers and those who bash frequently, the performance and longevity benefits make the Fastrax upgrade worthwhile.
- Do I need any special tools to install these caster blocks? — No special tools are required beyond the basic hex wrench set you likely already use for RC car maintenance. The installation procedure follows standard RC car suspension work practices and should take only a few minutes per side.
- Can I use these on Micro-T and Micro-B simultaneously? — Yes, if you own both vehicles, a single pair of these caster blocks can only be installed on one vehicle at a time. However, many UK RC enthusiasts maintain separate upgrades for each vehicle to avoid having to swap components between platforms.
