Key Features

• 6061-T6 Aluminium Construction — Each housing is carefully machined from tough 6061-T6 aluminium, which is an aerospace-grade alloy renowned for its exceptional strength-to-weight ratio, precision machinability, and resistance to corrosion. This material choice ensures your portal housings will withstand the stresses of rock crawling, bashing, and trail running without flexing, cracking, or deforming over time.
• Brilliant Red-Anodised Finish — The aluminium is coated with a high-tech anodized finish that provides both visual impact and functional protection. Anodising creates a hard oxide layer on the surface that resists corrosion, prevents oxidation, and protects the underlying aluminium from weathering, ensuring your housings maintain their vibrant red appearance for years to come.
• Precision Machining — These portal housings are machined to exacting tolerances, ensuring perfect dimensional accuracy and ideal fit on all compatible TRX-4 models. The precision engineering guarantees smooth axle rotation, minimal play, and reliable long-term performance even under extreme load and stress.
• OEM Traxxas Design — Manufactured by Traxxas specifically for Traxxas vehicles, these housings are designed to integrate seamlessly with all compatible TRX-4 platforms. Unlike generic aftermarket alternatives, you can be confident that these parts will fit perfectly and perform exactly as intended without modification or adjustment.
• Includes Hardware — The set comes complete with all necessary 2.5x10 mm cross-slot machine screws (12 pieces), so you have everything needed to install the housings immediately upon receipt. No hunting for the correct fasteners or making additional purchases required.
• Portal Axle Enhancement — Portal housings are critical to the structural integrity and performance of your portal axles, and upgrading to aluminium options significantly improves rigidity, heat dissipation, and overall reliability compared to plastic alternatives commonly found on entry-level crawlers.

Technical Performance

The 6061-T6 aluminium used in these portal housings represents a significant upgrade in material quality and engineering precision. 6061-T6 is a heat-treated aluminium alloy that offers exceptional strength combined with excellent machinability, making it the preferred choice for precision-engineered RC components used in demanding applications. The machining process ensures that every housing is produced to exact specifications, eliminating the dimensional variance that can occur with plastic moulded parts. The red-anodised finish applied post-machining creates a protective oxide layer approximately 0.0005 inches thick that prevents corrosion and oxidation whilst also adding visual distinction to your build. These housings are engineered to work flawlessly with all compatible TRX-4 models, including the Chevrolet K10 Cheyenne High Trail Edition, Ford F-150 Ranger XLT High Trail Edition, 1972 Chevrolet K5 Blazer, 1979 Chevy Blazer, Nissan Pathfinder SE-V6, 2021 Ford Bronco, TRX-4 Defender, TRX-4 Sport, and unassembled TRX-4 chassis kits. The precision fit ensures optimal portal axle alignment, smooth articulation, and maximum durability whether you're running a brushless or brushed motor configuration with battery power in your RC crawler.

Frequently Asked Questions

• Are these aluminium portal housings compatible with my TRX-4 model? — Yes, these Traxxas OEM portal housings are engineered for use across the entire TRX-4 range, including all High Trail Edition models (Chevrolet K10 Cheyenne, Ford F-150 Ranger XLT, Chevrolet K5 Blazer, 2021 Ford Bronco), the 1979 Chevy Blazer, Nissan Pathfinder SE-V6, TRX-4 Defender, TRX-4 Sport, and unassembled chassis kits. Always verify your specific model against the provided compatibility list, but virtually all standard TRX-4 variants will accept these housings without modification.
• Will these red-anodised housings scratch or fade? — Anodised aluminium is significantly more durable than painted finishes, and the oxide layer created during anodising is actually harder than the underlying aluminium itself. Whilst normal use and maintenance may result in some minor surface marks over extended periods, the red-anodised finish is engineered to resist corrosion and maintain its appearance in challenging UK outdoor conditions. Minor scuffs can often be polished out, and the protective properties of anodising mean the housings will remain functional and visually appealing for years.
• What is the advantage of aluminium portal housings over plastic ones? — Aluminium offers multiple performance advantages over plastic moulded housings found on entry-level crawlers. Aluminium has superior strength and rigidity, which means zero flex under load and improved axle alignment consistency. It dissipates heat more effectively, which is beneficial during extended running sessions. Aluminium does not warp or degrade from UV exposure or temperature extremes. Precision machining ensures tighter tolerances and better fit. Finally, aluminium housings simply look more professional and finished, enhancing the overall aesthetic of your build.
• Do I need to modify my TRX-4 to install these housings? — No modification is required. These are OEM Traxxas components engineered specifically for Traxxas TRX-4 vehicles, so they install with a perfect fit using the provided 2.5x10 mm screws. Simply remove your existing housings and bolt these aluminium versions in place—installation takes minutes with basic tools.
• Are these housings suitable for high-speed running or just rock crawling? — Portal housings are a structural component that contributes to overall axle rigidity and reliability regardless of running style. Whilst these housings are optimally suited for the TRX-4 platform which is primarily designed for low-speed rock crawling and trail running, the upgraded aluminium construction will improve durability and performance in any TRX-4 configuration you're running, whether that's primarily crawling, light bashing, or mixed-use trail running.
• What tools will I need to install these portal housings? — You'll need a screwdriver suitable for cross-slot (Phillips head) fasteners and a socket or wrench set to remove existing housings if they're currently installed. The installation process is straightforward and within the capabilities of any RC enthusiast, even those relatively new to the hobby of RC cars in the UK.
