This genuine Traxxas spare part is designed to fit either the left or right side of your RC crawler's rear portal axle assembly, making it incredibly versatile for repairs, maintenance, or performance upgrades.

The portal drive housing is a critical component in the TRX-4's legendary crawling capability, enabling the extreme ground clearance and articulation that makes these vehicles perfect for rocky terrain and challenging obstacle courses across the UK.
Portal drive housings are integral to the TRX-4's unique design philosophy, which prioritises maximum wheel travel and suspension geometry over traditional approaches. If you own any TRX-4 variant—whether it's the Chevrolet K10 Cheyenne High Trail Edition, Ford F-150 Ranger XLT, 1972 Chevrolet K5 Blazer, 1979 Chevy Blazer, Nissan Pathfinder SE-V6, or 2021 Ford Bronco edition—this spare part is directly compatible with your crawler. This replacement housing ensures your vehicle's front and rear axles operate at peak efficiency, maintaining the precise angles and tolerances that Traxxas engineers designed into these premium RC trail trucks.
RC Model Shop stocks genuine Traxxas spare parts because we understand that serious RC enthusiasts demand authenticity and reliability. These portal drive housings come as a pair (two pieces), allowing you to replace or upgrade both sides of your rear axle assembly simultaneously, or to keep a spare set on hand for intensive driving sessions. For anyone exploring the world of scale RC crawling in the UK, understanding and maintaining these critical drivetrain components is essential to getting the best performance and longevity from your investment.

Technical Performance
The Traxxas Portal drive housing, inner, rear (TRX8253) represents decades of RC engineering refinement at the forefront of scale crawling technology. Portal axles are distinctive to premium Traxxas TRX-4 vehicles and represent a significant departure from traditional RC truck designs, positioning the differential above the tyre centreline rather than through the middle. This engineering choice provides massive benefits for trail performance: it maximises ground clearance, allows extreme wheel articulation, and enables the TRX-4 to tackle obstacles that would stop conventional RC vehicles. The inner portal drive housing specifically contains critical bearing surfaces and gear engagement points that must maintain precise tolerances to ensure smooth operation, positive power delivery, and minimal drivetrain noise. Traxxas engineers have specified exact material properties and manufacturing tolerances for these housings to withstand the constant stress of rock crawling, mud running, and serious off-road use. The housing works in conjunction with the outer portal drive housing, portal gears, and differential assembly to create a robust yet refined drivetrain system. Whether you're running on rocky hillsides, technical obstacle courses, or challenging trail routes throughout England, Scotland, Wales, and Northern Ireland, these housings maintain the engineering integrity that makes TRX-4 crawlers the benchmark for serious RC enthusiasts.

Frequently Asked Questions
- Which TRX-4 models does the TRX8253 fit? — This portal drive housing is compatible with a comprehensive range of TRX-4 variants including the Chevrolet K10 Cheyenne High Trail Edition (available in red, metallic blue, black, and metallic copper), Ford F-150 Ranger XLT High Trail Edition (brown, blue, and black), 1972 Chevrolet K5 Blazer High Trail Edition (blue and red), 1979 Chevy Blazer with Clipless Body (black and red), Nissan Pathfinder SE-V6 3S (red and silver), 2021 Ford Bronco (red, white, orange, and black), TRX-4 Defender (red, silver, green, and sand), TRX-4 Sport (multiple colours), and the unassembled TRX-4 chassis kit. If you own a TRX-4 model, this part almost certainly fits your vehicle.
- Do I need to replace both housings at the same time? — Whilst you only need to replace one side if just one housing is damaged, Traxxas recommends replacing both rear portal drive housings simultaneously to maintain balanced performance and even wear characteristics across the rear axle assembly. The pair packaging makes this convenient and cost-effective.
- How do I know if my portal drive housing needs replacement? — Signs that your portal drive housing may need replacement include visible cracks or breaks in the plastic housing, metallic debris in your differential oil, grinding or unusual noises from the rear axle during crawling, or difficulty maintaining traction during rock crawling. If you've had a serious impact or crash, inspecting the housings is recommended.
- Is this a suitable spare part for a beginner RC crawler enthusiast? — Whilst the TRX-4 itself is renowned as an excellent platform for both beginners and advanced users, replacement of the portal drive housing requires some mechanical knowledge and familiarity with differential and axle assembly. However, if you're operating a TRX-4 actively, having spare housings on hand is a smart investment for continued operation.
- How do portal drive housings differ from standard axle housings? — Portal axles position the differential above the tyre centreline, creating a distinctive housing that provides maximum ground clearance and wheel travel—critical features that make the TRX-4 superior for technical rock crawling compared to traditional RC truck designs.
