RC car enthusiasts across the UK have long recognised the Losi Micro-B as one of the finest small-scale platforms available, and genuine Fastrax upgrade parts like this gearbox housing ensure your investment continues to perform at its peak. This is not merely a replacement part — it is a genuine performance upgrade that reflects the exacting standards of competitive RC racing and off-road driving.

Key Features

• Premium Aluminium Construction — Manufactured from high-grade aluminium rather than plastic, this gearbox housing provides superior strength and rigidity whilst remaining lightweight, which is crucial for maintaining the balance and handling characteristics of your Micro-B platform.
• Integrated Motor Mount — The design combines gearbox housing and motor mounting functionality in one precision component, eliminating multiple connection points and the associated wear, flex and misalignment that can develop over time with separate parts.
• Enhanced Heat Dissipation — Aluminium naturally conducts heat away from the gearbox and motor more effectively than plastic, keeping critical drivetrain components cooler during intense racing or bashing sessions, which directly extends component lifespan and maintains consistent performance.
• Perfect Motor Alignment — The precision-engineered mounting ensures your motor sits in perfect alignment with the gearbox, eliminating gear mesh problems and power loss that result from misalignment, whilst also reducing vibration and noise.
• Durability and Longevity — The rigid aluminium construction resists warping and deformation that can occur in plastic housings during intense use or temperature changes, meaning this upgrade will maintain its performance characteristics for years of reliable service.
• Fastrax Quality Assurance — As an authorised Fastrax component, this part is manufactured to the same exacting standards as all genuine Fastrax products, ensuring compatibility and performance with your existing Losi Micro-B setup.
• Direct Bolt-In Installation — Designed specifically for the Losi Micro-B platform, this component installs directly without modification, making upgrading straightforward for users of all experience levels.

Technical Performance

This gearbox housing represents a significant engineering upgrade over standard plastic components found on stock Losi Micro-B vehicles. The use of aluminium alloy provides superior rigidity compared to injection-moulded plastics, which means less flex during hard cornering, acceleration and deceleration. This directly translates into more predictable handling characteristics and improved consistency lap after lap. The integrated motor mount design ensures your brushed or brushless motor maintains perfect mesh with the gearbox pinion throughout extended driving sessions, eliminating the performance loss and premature wear that occurs when motor geometry shifts even slightly. The superior thermal conductivity of aluminium means heat generated during high-speed runs or continuous bashing is dissipated more efficiently, keeping the gearbox oil, bearings and motor windings at lower operating temperatures. This cooling benefit is particularly valuable during competitive racing events where maintaining consistent performance across multiple heats is essential. For RC enthusiasts running the popular Losi Micro-B platform with either brushed or brushless drivetrain configurations, this Fastrax component delivers measurable improvements in reliability, handling precision and longevity. The professional-grade materials and construction methods reflect the demands of competitive RC racing, making this suitable for both serious racers and dedicated hobbyists seeking the best performance from their Micro-B platform.
