Does anyone know if/when the AT4X HD suspension will be available as a standalone purchase to upgrade, for example, a regular AT4? Asking for a friend who has some hardcore parking lot terrain to deal with...

Thanks! As gemarsh said, I'm looking for the HD version (updated title to reflect that).ZR2/AT4X Spec Front and Rear DSSV Shock System

I would not jump to it just yet. I'm still struggling with my 2024 Sierra 2500HD AT4X AEV Edition purchased less than a month ago and ride issues from day 1. GMC were no help. I changed all five tires at my own expense which somewhat improved the situation yet there is strange intolerable vibration coming up through the seats (likely suspension issues). I'm still trying to figure it out and now looking for a more sympathetic and intelligent dealer/tech who is familiar with this vehicle.Does anyone know if/when the AT4X HD suspension will be available as a standalone purchase to upgrade, for example, a regular AT4?

Dang, sorry to hear that's happening to you. Super frustrating dealing with issues on a new vehicle. Is it only at certain speeds or does it happen at some level all the time?I would not jump to it just yet.
