The anodised finish in green gives your TRX-4 a distinctive, professional appearance that sets it apart from stock builds.

Key Features

• 6061-T6 Aluminium Construction — These portal housings are machined from tough 6061-T6 aluminium alloy, a material renowned for delivering maximum strength without excessive weight. This grade of aluminium is stronger than standard grades whilst remaining lightweight, making it ideal for high-performance RC crawler applications where durability under stress is critical.
• Green Anodised Finish — The brilliant green anodised coating provides dual benefits: it delivers a striking, professional appearance that enhances the visual appeal of your TRX-4, and it offers superior corrosion resistance and wear protection. This protective layer ensures your housings remain in pristine condition even after extended use in challenging terrain and weather conditions typical of UK trail driving.
• Genuine Traxxas Manufacturing — These are authentic Traxxas accessories made by Traxxas specifically for Traxxas vehicles, guaranteeing perfect factory fit every time. This eliminates compatibility concerns and ensures seamless integration with your TRX-4's drivetrain, transmission, and differential systems without modification or adjustment.
• Precision Machining — Each housing is precision-machined to exact specifications, ensuring perfect alignment and fit within the portal axle assembly. This level of precision is critical for maintaining the integrity of your crawler's four-wheel drive system and ensuring optimal weight distribution across all four wheels.
• Rear Portal Housing Configuration — Specifically designed as rear inner portal housings, these components mount on the inside of the rear portal axle assembly. The rear placement is crucial for maintaining the TRX-4's articulation and ground clearance in demanding crawling scenarios.
• Includes Hardware — Each package includes two portal housings plus two 2.5x10 CS (cap screw) fasteners, everything needed for a complete installation without hunting for additional hardware or making trips to specialist shops.

Technical Performance

The engineering behind these Traxxas portal housings speaks to the company's commitment to RC crawler excellence. 6061-T6 aluminium is an aerospace-grade material that delivers exceptional tensile strength of approximately 275 MPa (40,000 PSI), making it significantly stronger than cast alternatives whilst remaining considerably lighter. This material choice means your TRX-4's portal axle assembly can handle the stresses of extreme articulation, rock crawling, and high-load scenarios without flexing or fatigue cracking. The anodising process adds a protective layer measuring 0.0008 to 0.002 inches thick, which not only shields the aluminium from oxidation and corrosion but also increases surface hardness, reducing wear from mechanical friction during assembly and disassembly. For UK RC enthusiasts tackling wet, muddy, and challenging terrain, this corrosion resistance is invaluable. These rear inner housings work in conjunction with the front portal housings to create the complete portal axle system that defines the TRX-4's exceptional ground clearance and articulation capabilities — key features that make the TRX-4 one of the most capable crawlers available for serious scale rock crawling and technical terrain navigation.

Frequently Asked Questions

• Will these portal housings fit my TRX-4 model? — Yes, these rear inner portal housings are specifically designed as genuine Traxxas components for the TRX-4 range, including all TRX-4 variants such as the TRX-4 Chevrolet K10 Cheyenne High Trail Edition, TRX-4 Ford F-150 Ranger XLT High Trail Edition, TRX-4 Nissan Pathfinder, TRX-4 1972 Chevrolet K5 Blazer, TRX-4 1979 Chevy Blazer, TRX-4 2021 Ford Bronco, TRX-4 Defender, and TRX-4 Sport models. Traxxas guarantees perfect factory fit every time with genuine accessories.
• What makes aluminium portal housings better than plastic ones? — Aluminium portal housings offer several significant advantages over plastic alternatives. Aluminium is considerably stronger and more durable, resisting the cracking and flexing that can occur in plastic components under load. The 6061-T6 grade used here provides excellent strength-to-weight ratio, meaning you gain durability without adding unnecessary weight to your crawler. Additionally, the green anodised finish provides corrosion resistance and a more professional, finished appearance that makes your TRX-4 stand out at the track or trail.
• Can these be used on the front of my TRX-4? — These are specifically rear inner portal housings. Whilst the manufacturer page notes that standard portal housings fit front or rear, these TRX8253G units are identified as rear-specific components. For a complete matched set, consider also upgrading your front portal housings for consistency and optimal performance across your entire crawler.
• Are these components suitable for beginners? — Yes, absolutely. These are genuine OEM Traxxas parts, meaning they install using standard tools and Traxxas' well-documented assembly procedures. If you're comfortable performing basic maintenance on your RC crawler — and these housings may be replaced during routine maintenance — then installation is straightforward. However, if you're new to RC and unsure about drivetrain work, we recommend consulting your vehicle manual or contacting RC Model Shop for guidance.
• How do I know these are genuine Traxxas parts? — Genuine Traxxas components like these portal housings come with proper packaging, clear part numbering (TRX8253G), and EAN coding (020334825360). When you purchase from RC Model Shop, an authorised Traxxas retailer, you receive guaranteed genuine products with full manufacturer backing and warranty support.
• Will green anodised housings fade or discolour? — The anodising process creates a protective oxide layer that is integral to the aluminium surface, not a paint or coating that can chip away. The green colour is exceptionally durable and resistant to fading from UV exposure or weathering. Normal use in UK outdoor conditions will not noticeably affect the colour or finish. The anodising also provides excellent protection against salt spray, mud, and moisture.
