Overview

The Fastrax ARRMA Aluminium Diff Housing for 1/8 Kraton 6S is a premium upgrade component designed for serious RC enthusiasts who demand durability and performance from their high-speed brushless RC cars. Whether you're running your ARRMA Kraton 6S hard on the track or bashing in the backyard, this aluminium differential housing offers a significant step up from standard plastic components. Built by Fastrax, a recognised name in RC performance parts, this housing is engineered to withstand the extreme torque and stresses generated by powerful 6S LiPo setups, making it an essential upgrade for anyone looking to extend their vehicle's lifespan and improve reliability.

The distinctive red anodised finish isn't just for looks—it represents quality engineering and precision manufacturing. This diff housing is specifically engineered for ARRMA 6S vehicles (excluding the EXB models), making it a perfect fit for the Kraton 6S and other compatible 6S models in the ARRMA lineup. If you're serious about RC performance, UK-based RC enthusiasts know that upgrading critical drivetrain components like the differential housing can make the difference between frequent repairs and reliable long-term performance. This is exactly the kind of upgrade recommended for anyone running their RC truck or buggy regularly.

Fastrax components are trusted by RC competitors and weekend bashers alike across the UK and internationally. This aluminium diff housing combines lightweight construction with exceptional strength, ensuring your ARRMA 6S can handle the power delivery of high-performance brushless systems without compromising durability. Whether you're upgrading from a stock plastic housing or replacing a damaged component, this Fastrax unit represents a smart investment in your RC car's longevity and reliability.

Key Features

• Aluminium Construction — The housing is manufactured from aluminium alloy, which provides superior strength and durability compared to plastic alternatives whilst keeping weight to a minimum, resulting in better handling characteristics and improved power delivery from your brushless motor.
• Premium Anodised Red Finish — The anodised coating not only gives the housing an attractive appearance but also provides corrosion resistance and additional surface hardening, protecting the component from wear and environmental damage during outdoor use.
• ARRMA 6S Compatibility — Specifically designed for ARRMA 6S vehicles (excluding EXB models), ensuring a perfect mechanical fit and optimal performance with your existing drivetrain components, including the stock gearing and internal diff mechanisms.
• High-Torque Performance — Engineered to withstand the extreme stresses generated by 6S LiPo batteries and brushless motors, which can deliver significant torque to the drivetrain, making this housing ideal for aggressive driving styles and competition use.
• Fastrax Quality Assurance — Manufactured by Fastrax, a trusted supplier of RC performance parts, ensuring precision engineering and consistent quality across all units, backed by a company with extensive experience in the RC hobby sector.
• Direct Replacement Component — This is a transmission tune-up option that installs as a direct replacement for the stock housing, making the upgrade straightforward and requiring no additional modifications to your vehicle setup.

Technical Performance

The Fastrax ARRMA Aluminium Diff Housing represents a significant engineering upgrade over standard plastic housings commonly found on stock ARRMA 6S vehicles. Aluminium alloy construction provides approximately three to four times the tensile strength of engineering plastics, meaning it can withstand the enormous forces generated when running a 6S LiPo battery pack through a brushless motor system. The 6S power envelope—typically 22.2 volts at full charge—can produce sustained current draws exceeding 100 amps under load, generating rotational forces that frequently cause plastic housings to crack or strip. This Fastrax unit absorbs those stresses with ease, distributing loads evenly across the housing walls through precision manufacturing. The anodised finish adds a hardened surface layer, further improving resistance to impact damage and corrosion from dirt, water, and salt exposure. For UK RC enthusiasts running their vehicles in variable weather conditions, this corrosion resistance is particularly valuable. The housing maintains tight tolerances throughout, ensuring smooth differential operation and consistent power delivery to both wheels under acceleration, cornering, and braking scenarios. Weight savings from the aluminium construction compared to heavier plastic reinforced options contribute to improved acceleration and handling characteristics, particularly noticeable during high-speed runs and competitive racing where every fraction of a second counts.

What's in the Box

• Fastrax ARRMA Aluminium Diff Housing in red anodised finish

What You Need to Complete

Frequently Asked Questions

• Is the Fastrax aluminium diff housing compatible with all ARRMA 6S models? — This housing is specifically designed for ARRMA 6S vehicles but does not fit EXB models. It is compatible with the ARRMA Kraton 6S and other standard 6S platform vehicles. Always verify your specific model before ordering to ensure correct fitment.
• What are the advantages of upgrading to an aluminium diff housing? — Aluminium housings offer substantially improved durability, corrosion resistance, and strength compared to plastic alternatives. They can withstand higher torque loads from brushless motors and 6S LiPo batteries without cracking, making them ideal if you drive aggressively or run your RC car frequently.
• Will this housing improve my RC car's performance? — While the housing itself doesn't increase top speed or acceleration directly, upgrading to aluminium prevents performance loss caused by damaged or stripped plastic housings. By maintaining structural integrity under load, you preserve the efficiency of power transfer from motor to wheels, ensuring consistent performance.
• Is installation difficult for someone new to RC maintenance? — Installation is straightforward for anyone with basic RC maintenance experience. The housing is a direct replacement component requiring only standard hex wrenches and screwdrivers. If you've performed basic RC upgrades before, you'll find this installation routine. However, if you're entirely new to RC maintenance, consider watching online installation guides or visiting a local RC shop for guidance.
• How long does an aluminium diff housing typically last? — Aluminium housings are extremely durable and can last through thousands of hours of driving. Longevity depends on your driving style, maintenance practices, and maintenance of internal diff gears. Regular inspection and appropriate diff oil changes ensure maximum lifespan.
• What diff oil should I use with this housing? — The appropriate diff oil thickness depends on your driving conditions and style. Lighter oils work well for racing and high-speed running, whilst thicker oils suit bashing and demanding terrain. Fastrax produces diff oils in various viscosities; check their recommendations for your specific driving application.
• Can I use this housing with a 4S or 3S LiPo battery instead of 6S? — Yes, the housing is compatible with lower voltage systems as well. However, it's engineered to handle the extreme demands of 6S power. Using it with 3S or 4S batteries will actually reduce stress on the component, extending its life even further if you decide to run variable setups.
