Air suspension has nothing to do with factory designated payload max and safe towing. In fact, the air makes for a softer and less planted rear end than leaf springs when towing. Coils and bags really are not as good as leafs.
Good sir, I will disagree with the first part of this.
Yes, I think the leaf springs in the rear are better at load management than COIL springs, On that part I agree.
But the ram air suspension handles heavy loads in the rear better than basically every other factory setup - save for perhaps MAYBE the uber high payload package Ford has. (With VERY heavy springs, like 10inches of rake,
and it rides like it too).
Yes, the Air suspension is cushy when unloaded, but the whole point is that it stiffens up as it senses weight in the back.
I kick myself for not saving the picture, I've seen a photo of an air suspension truck loaded with I want to say, 2,400lbs of material in the bed?
It had boxes that I believe had their weight on them, I want to say it was 47lbs a piece or more. There were a TON of these boxes in the back. I want to say it was a dark blue Ram, 2016 body style, the tailgate is down in the photo. He was WAY over GVWR. I can remember the damn image but I can't find it on my hard drive.
A 2,400lb+ load would have put another Ram on its bumpstops, and likely most leafspring 1/2ton trucks as well.
Not so for the air suspension.
While I fully, fully recommend everyone stick within manufacturers ratings? In a "on private roads only with no other drivers setting", the ram air suspension is stupid-strong, wayyyy over what the doorsticker says it will do.
I can say on my old ram with an air suspension, the door sticker "may or may not have been" Sub 900lbs.
I may or may not have had roughly 1,200lbs of payload in the bed. The control the suspension had over that load in turns and bumps was amazing. No porpoise-ing up and down at all.
It really is a beautiful system in terms of how nice it can ride on the road, AND how well it can handle loads.
That's what they're so proud of - and that's also why I believe we're seeing air suspensions in both the Cybertruck AND Hummer.
The Hummer's like 9000lbs BUT it also has to ride nice enough to justify being a $100,000 grocery getter for those who will buy them.
Air suspension is how they'll do it.
For the Gen5 Ram, I opted out of the air ride because I wanted to change the suspension and keep my options open for lifting it.
Lower cost as well.
AND I'm wary of how they will hold up in this cold climate up here longterm (I intend on buying the truck and keeping forever).
Not on the list? Ride and payload handling. Both are great!
