"Realistically these new portal axles aren’t for everyone. They are not recommended for highway use, and the leverage of the portal design places additional stress on suspension mounting points and control arms. Electronic controls such as ESP and ABS cannot be retained with the portal boxes, as they can with Dynatrac’s traditional ProRock, Pro, and Trail Series axles. There is no provision for a standard parking brake; however a driveline brake at the transfer case can easily be added to address this issue. Final suspension design will be determined by many factors and it is crucial that the suspension design address the added torque and leverage of the portal system. The end user will need to design proper steering and a strong 4-link suspension. Therefore, it’s important that a qualified specialist with fabrication skills and a thorough knowledge of suspensions install it. In short, this isn’t a ‘turn-key’ assembly that fits any application. With the caveats out of the way, it becomes clear that if you require the absolute greatest ground clearance, with gear reduction to overcome the most severe, boulder-strewn trails and obstacles, there is no substitute for Dynatrac and Mopar axles equipped with AIM portal housings."
