Question:
What is the difference between this model and PB56SV? They both say they fit a 2025 Trail Boss. Is there anything else you would recommend for a 2025 Chevy Silverado 2500HD Trail Boss?

Hey Ken!
The Pacbrake Alpha HD Pro Air Bag # PB36SV you're looking at has internal jounce bumpers while the Kit # PB56SV you're comparing it to doesn't. Internal jounce bumpers help to ensure your Trail Boss won't bottom out (metal on metal) if there ever is a time that the air bags fail.
I know it seems like Pacbrake isn't as confident in their air bags if they have this feature built-in, but it's more like an insurance policy than anything.
What's the main purpose of using the air bag kit on your Trail Boss? Would you be interested in a compressor kit as well?

I have a gas 2500, not diesel, and would like to make the ride a bit more comfortable when towing. I was hoping to just put bump stops on, but none say they fit the trail boss.
