Overview
Upgrade your Traxxas TRX-4 crawler with genuine Traxxas Portal housings, inner (Rear) in striking red-anodised aluminium. These precision-engineered components are essential for anyone serious about maximising their RC crawler's performance and durability. Whether you're a dedicated trail enthusiast tackling challenging terrain across the UK or a weekend basher pushing your rig to its limits, these portal housings deliver the strength and reliability that Traxxas is renowned for. As official Traxxas spare parts, they guarantee perfect factory fit and compatibility with your TRX-4 platform every single time.
Portal housings are critical structural components that house your differential gears and provide the mounting point for your portal axles. When you're crawling over rocks, splashing through water, or navigating technical terrain, these housings bear significant stress. The original equipment may show wear over time, or you might want to upgrade to a fresh set to breathe new life into your RC car. Traxxas Portal housings, inner (Rear) in red-anodised aluminium represent a genuine factory upgrade that serious RC enthusiasts and competitive crawlers depend on.
This pack includes everything you need for a complete rear housing upgrade: two portal housing units plus four stainless steel fasteners (2.5x10 CS screws). The red anodised finish not only looks fantastic on your TRX-4 but also provides enhanced corrosion resistance and durability compared to bare aluminium. If you're building a custom colour scheme or replacing damaged housings, these rear inner portal housings from Traxxas are the authentic choice for genuine TRX-4 owners throughout the UK.
Key Features
- 6061-T6 Aluminium Construction — Machined from premium 6061-T6 aluminium alloy, these portal housings deliver exceptional strength-to-weight ratio that serious RC crawlers demand. This specific alloy is chosen by manufacturers worldwide for its excellent machinability, corrosion resistance and structural integrity under load, ensuring your differential gears are protected in the toughest conditions.
- Red-Anodised Finish — The brilliant red anodised coating serves multiple purposes: it provides superior corrosion protection against moisture and mud exposure, enhances visual appeal with a professional factory appearance, and helps prevent galvanic corrosion between different metal components when used alongside other aluminium and steel parts on your TRX-4.
- Genuine Traxxas Factory Parts — These are authentic Traxxas components designed and manufactured by Traxxas themselves, ensuring perfect fit and compatibility with your TRX-4 platform. Unlike generic alternatives, genuine Traxxas spares are engineered to exact specifications and have been tested to work seamlessly with all other OEM components on your vehicle.
- Rear Inner Portal Configuration — Specifically designed for rear axle installation, these inner portal housings are precisely engineered for the TRX-4's advanced portal axle system, which provides excellent ground clearance and articulation for extreme trail crawling and obstacle navigation.
- Complete Hardware Included — Each pack includes two portal housing units plus two stainless steel 2.5x10 CS screws, providing everything needed for installation. The stainless steel fasteners resist corrosion and seizure, particularly important when your RC crawler is exposed to wet conditions and mud.
- Maximum Durability Under Load — The machined aluminium construction and robust design mean these housings can withstand the immense torque and stress placed on them during aggressive crawling, rock crawling, and competitive off-road use without flexing or failing.
Technical Performance
These Traxxas Portal housings, inner (Rear) represent the pinnacle of RC crawler component engineering. Machined from 6061-T6 aluminium, they combine exceptional strength with minimal weight addition to your TRX-4 platform. The material choice is deliberate: 6061-T6 offers outstanding machinability for precision tolerances, excellent fatigue resistance during repeated articulation cycles, and superior corrosion resistance compared to lower-grade aluminium alloys. The red anodised finish adds approximately 0.025mm of protective coating, providing a barrier against moisture, salt spray, and chemical exposure from trail environments. For TRX-4 owners in the UK who regularly crawl in wet conditions, this corrosion protection is invaluable for maintaining resale value and component longevity. The inner portal housing design works in conjunction with the TRX-4's portal axles to create the vehicle's legendary approach and departure angles, essential for navigating boulder-strewn trails and technical rock crawling sections. Installation requires basic mechanical knowledge and standard RC tools, making these suitable for intermediate to advanced builders and enthusiasts. When combined with other quality Traxxas components, these housings ensure consistent performance season after season of serious crawling.

Frequently Asked Questions
- Are these portal housings compatible with all TRX-4 models? — These inner portal housings are designed specifically for rear axle installation on Traxxas TRX-4 platform vehicles. They are compatible with all current and recent TRX-4 variants including the TRX-4 Sport, TRX-4 Defender, TRX-4 Chevrolet Blazer, TRX-4 Ford F-150 Ranger, TRX-4 Nissan Pathfinder and many other TRX-4-based models. As genuine Traxxas parts, they guarantee perfect factory fit. Always verify your vehicle uses the TRX-4 platform before ordering.
- What is the advantage of aluminium portal housings over plastic alternatives? — Aluminium housings offer significantly superior durability, strength, and longevity compared to plastic. They resist deformation under load, provide better heat dissipation from the differential, maintain precise tolerances over extended use, and ultimately deliver better value through longer service life. For serious crawlers and competitors, aluminium is the standard choice.
- How do I install these portal housings on my TRX-4? — Installation involves removing your existing rear inner portal housings and fasteners, then installing these new units with the included 2.5x10 CS screws. You'll need basic tools like hex wrenches and screwdrivers. Detailed installation guides are available in the Traxxas TRX-4 assembly manual. If you're unfamiliar with RC maintenance, consider having these installed by an experienced friend or local RC hobby shop.
- Why choose the red-anodised finish? — The red-anodised finish is not just cosmetic. Anodising creates a protective oxide layer that significantly improves corrosion resistance, particularly valuable when your RC crawler is exposed to wet UK conditions, mud, and salt environments. The finish also helps prevent galling and seizure of fasteners, and creates a professional appearance that matches factory TRX-4 aesthetics.
- Are these suitable for competitive rock crawling? — Absolutely. These are genuine Traxxas factory parts used by competitive crawlers and serious enthusiasts throughout the world. The 6061-T6 aluminium and robust machining make them perfectly suited for aggressive rock crawling, competition events, and extreme trail use.
- What tools do I need to install these? — Basic RC maintenance tools including hex wrenches, screwdrivers, and possibly a small adjustable wrench for removing fasteners. No specialised equipment is required. A service manual for your specific TRX-4 model will provide detailed installation steps.
