Technical Performance
Stub axles are precision-engineered components that connect the differential to the portal gearboxes in Traxxas TRX-4 portal drive setups. The extended profile of these TRX8255A units is specifically dimensioned to provide optimal geometry in portal drive configurations, where the differential sits higher on the chassis to maximise ground clearance. The extended design ensures proper alignment with the portal axles and maintains correct suspension geometry across the full range of articulation that modern rock crawlers demand. These components are manufactured to Traxxas's exacting standards using durable materials capable of withstanding the extreme forces encountered when crawling over rocks, roots, and uneven terrain. Users have confirmed excellent fitment with both standard and modified hubs, including compatibility with +3mm brass hubs, demonstrating the precision manufacturing tolerances Traxxas maintains. The portal drive system as a whole has become the benchmark configuration for serious 1/10 scale crawlers in the UK and worldwide, and maintaining genuine components like these stub axles ensures your TRX-4 performs at its intended level.
