Technical Performance
These Traxxas portal housings represent the pinnacle of aluminium RC component engineering. Fabricated from 6061-T6 aluminium—the same aerospace-grade material used in demanding applications across the aviation and automotive industries—these housings deliver exceptional rigidity without unnecessary weight. The 6061-T6 alloy is renowned for its excellent machinability, which allows Traxxas engineers to achieve the precise tolerances and complex geometries necessary for perfect fitment with your TRX-4 chassis. The green anodised finish is applied through a specialised electrochemical process that creates a hard, protective oxide layer bonded directly to the aluminium surface. This anodised coating is significantly harder than the base aluminium and provides exceptional resistance to corrosion, abrasion, and the chemical attack from saltwater, mud, and aggressive cleaning products commonly encountered during UK off-road RC driving. The anodising process also provides excellent colour depth and vibrancy, ensuring your truck maintains its striking appearance through countless hours of use. The front inner portal housings are critical structural components that support your truck's portal axle system and transmit steering and suspension forces to the chassis. By upgrading from plastic alternatives to precision-machined aluminium, you dramatically increase the stiffness of this joint, reducing flex and improving responsiveness. This translates directly to more predictable handling, sharper cornering, and improved stability on rough terrain. The included 3x12mm ball cap screws feature pre-applied threadlock, eliminating the need for additional thread-locking compound and ensuring your housings remain secure through aggressive driving, jumping, and rock crawling without rattling loose.

Frequently Asked Questions
- What is the difference between inner and outer portal housings? — Inner portal housings sit closest to the truck's chassis and form the primary load-bearing interface between the portal axle and the main frame. Outer housings mount to the wheels and support the wheel hubs. Both sets can be upgraded for maximum durability, but inner housings are especially important for maintaining chassis rigidity and overall truck stiffness.
- Are these housings compatible with my TRX-4? — Yes, these Traxxas-designed housings are engineered specifically for the TRX-4 platform and guarantee perfect fitment. Traxxas manufactures these parts for Traxxas vehicles, ensuring complete compatibility without modification. If you own a TRX-4, TRX-4M, or TRX-4 Tactical Unit, these will fit perfectly.
- Can I mix and match anodised colours? — Absolutely! Many RC enthusiasts create custom colour schemes by combining different anodised colours from the Traxxas lineup. The green anodised housings coordinate beautifully with other Traxxas anodised components, allowing you to develop a cohesive, professional appearance across your entire truck's aluminium components.
- Will upgrading to aluminium housings improve my truck's performance? — Yes, upgrading from plastic to aluminium housings noticeably improves handling and responsiveness. Aluminium is approximately four times more rigid than the plastic used in standard components, which significantly reduces flex in the portal axle assembly. This results in crisper steering response, improved suspension geometry consistency, and better overall handling dynamics during competitive rock crawling and trail driving.
- How difficult is installation? — Installation is straightforward for anyone with basic RC maintenance experience. Simply remove the old housings using the appropriate hex wrench, clean the mounting surfaces, apply the included threadlock to the new screws, and install the new aluminium housings. The entire process typically takes 10-15 minutes per side with no special tools beyond your standard RC tool kit.
- Are these suitable for beginners? — While these housings are suitable for all skill levels, they are typically purchased as an upgrade rather than a part for new trucks. If you already own a TRX-4 and want to improve durability and appearance, these are an excellent beginner-friendly upgrade. Complete beginners should start with a ready-to-run TRX-4 kit and add these housings after gaining some experience.
- How does anodising compare to other finishes? — Anodising is superior to paint or powder coating for RC applications because the coloured oxide layer is actually bonded into the aluminium itself rather than sitting on top like paint. This means the colour is far more durable, resists chipping and fading better, and maintains its appearance through countless hours of use. The green anodised finish will look vibrant for years of RC adventure.
