Key Features

This premium material provides exceptional strength-to-weight ratio, ensuring your portal axles can withstand extreme forces without adding unnecessary mass to your TRX-4, which is especially important for maintaining agility and handling on technical terrain.
• Blue Anodised Finish — The brilliant anodised coating isn't merely cosmetic; it provides a protective barrier against corrosion, oxidation and the elements, ensuring these housings maintain their appearance and structural integrity through countless bashing sessions, water crossings and muddy adventures. The vibrant blue colour also gives your crawler that custom, high-tech look that stands out from stock builds.
• Precision Machining — Each housing is carefully machined to exact tolerances, guaranteeing perfect fit with all TRX-4 portal axle components. This precision engineering means hassle-free installation and optimal performance without any fitment issues or modifications required.

• Included Fasteners — The package includes two 3x12mm ball-cap screws (BCS) that are specifically engineered for these housings, ensuring you have everything needed for a complete installation without hunting for correct fasteners elsewhere.

Technical Performance

The structural integrity of your RC crawler depends entirely on the quality of its portal housings, and these Traxxas 6061-T6 aluminium components represent the gold standard in the industry. Machined from aerospace-grade 6061-T6 aluminium alloy, this material offers superior strength characteristics compared to cheaper plastic alternatives, resisting flex and deformation even under extreme articulation and high-traction climbing scenarios. The anodised finish provides a hardened surface layer that resists scratching, UV damage and corrosion from moisture, mud and salt water exposure—crucial for UK RC enthusiasts who frequently bash in varied weather conditions. These housings are engineered to work seamlessly with the TRX-4's advanced portal axle system, which has become the industry standard for serious rock crawlers and trail explorers. The precision tolerances ensure that drive forces are transmitted efficiently through the drivetrain without play or movement, maintaining the precise handling characteristics that make the TRX-4 such a respected platform among UK RC crawler enthusiasts. Installation is straightforward thanks to the included fasteners and the housings' perfect fit with OEM TRX-4 components, meaning you can upgrade your crawler in minimal time and get straight back to exploring those challenging trails. Whether you're upgrading from worn stock housings or building your TRX-4 for the first time, these aluminium components will provide years of reliable service and maintain the resale value of your machine.

Frequently Asked Questions

• Which Traxxas TRX-4 models are these portal housings compatible with? — These front inner portal housings are compatible with a wide range of TRX-4 models including the Chevrolet K10 Cheyenne High Trail Edition (available in red, metallic copper, blue and silver finishes), the Ford F-150 Ranger XLT High Trail Edition (in blue and black), the 1972 Chevrolet K5 Blazer High Trail Edition (in red and blue), the 1979 Chevrolet Blazer with clipless body mounting (in red and black), the Nissan Pathfinder SE-V6 3S model (in silver and red), the 2021 Ford Bronco 1/10 crawler (in red, white, orange and black), the Defender 4WD RTR (in green, sand, red and silver), and the TRX-4 Sport models (in various finishes). If you're unsure whether these housings are compatible with your specific TRX-4 variant, we recommend checking the official Traxxas compatibility list or contacting our UK team at RC Model Shop for confirmation before purchasing.
• Are these portal housings difficult to install? — No, installation is straightforward and hassle-free. These are genuine Traxxas components engineered to fit perfectly with OEM TRX-4 parts, meaning no modifications or special tools are required. The included 3x12mm ball-cap screws provide all the fasteners you need, and if you're familiar with basic RC car maintenance, you'll be able to swap these housings in under an hour. We recommend consulting your TRX-4's instruction manual for detailed installation guidance.
• Why choose aluminium portal housings over plastic alternatives? — Aluminium housings offer several significant advantages over plastic. Firstly, 6061-T6 aluminium is substantially stronger than injection-moulded plastic, resisting flex and deformation under the extreme loads experienced during rock crawling and technical terrain driving. Secondly, the anodised finish provides superior protection against corrosion, UV damage and wear compared to uncoated plastic. Thirdly, aluminium housings help maintain the precision of your drivetrain by eliminating play and movement, which translates to more precise steering, better articulation and improved climbing ability. Finally, aluminium components retain their appearance and structural integrity far longer than plastic, making them a better long-term investment for serious crawler enthusiasts.
• Will these blue housings match my other TRX-4 components? — The blue anodised finish is a popular colour choice that coordinates well with many TRX-4 builds and other Traxxas upgrades. However, Traxxas also offers these portal housings in red anodised finish (model TRX8252R) if you prefer a different colour scheme. The choice between blue and red is largely a matter of personal preference and how you want your crawler to look. Many UK RC enthusiasts choose to mix and match anodised colours to create unique, personalised builds.
• How durable are these housings for bashers and racers? — These housings are engineered for serious use, whether you're a competitive racer pushing your TRX-4 to the limit or a weekend basher enjoying rough terrain. The 6061-T6 aluminium material and anodised finish are designed to withstand countless impacts, articulation cycles and environmental exposure. However, like any RC component, durability depends on proper maintenance and use. Regular inspection, keeping fasteners tight, and protecting your crawler from extreme impacts will maximise the lifespan of these housings.
• Can I use these housings with aftermarket suspension upgrades? — Yes, these portal housings are compatible with the standard TRX-4 suspension geometry and will work with most aftermarket upgrades such as suspension arms and shock absorbers. However, if you're making significant modifications to your TRX-4's suspension setup, we recommend verifying compatibility with the specific aftermarket components you're using. The precision engineering of these housings means they'll work optimally with OEM and quality aftermarket parts that maintain the TRX-4's suspension geometry.
• Do I need any special tools to install these housings? — Installation requires only basic RC maintenance tools that most enthusiasts already have: a small hex wrench or Allen key set to remove fasteners, and potentially a small screwdriver for any clips or retainers. You won't need specialised tools or equipment. The straightforward design of these housings means installation is accessible to RC hobbyists of all experience levels.
