If your trying to get a lift from the 2025 springs I have an alternative if your interested. I have 2024 OT front springs and shocks with the Westcott lift installed and rear shocks with the lift installed as well. Approximately 4K miles
I have a Fonttek. It only cost $150 on sale and runs off it's own battery. I just set the PSI to my desired setting and pressure up. It's quick and I can do several trips with one charge. I agree with Yellow Lab. Why pay $1,800.
I think it was designed to look more aerodynamic, but I'm not sure if it has all the functionally as others. It's good for what I need it for. Thanks, I really like my GX
