So I’m sure some of yoy are aware of my overbuilt dually but I’m getting ready to paint this winter (hopefully) and what better time to address the suspension, right?

So I have the shackles flip I acquired from @sweetk30 a few years back that raise the rear an additional 4”.
The front is still sporting an unknown brand of 6” leafs that ride pretty decent with a big block overhead.
This setup leaves the truck almost level with maybe 1” shorter in the rear even with the tall one ton leaf packs. Yes I hate the squat too.

The plan is to make the truck a little better on the highway. Even with the Allison overdrive the 4.56 at a little short so 4.10 eventually with the doubler shout ensure it’s still very capable.

The other issue in question is the the ride. If you have a one ton you know exactly what I’m talking about. Anyway the hamster wheels of my brain are turning.

What ifffff, I swap to a 3/4 ton rear spring with auxiliary helper bags and lose an inch or 1.5 then I can swap the front springs for a +2” leaf essentially getting the rig back down to a height I may just be able to squeeze under a gooseneck trailer and use it as the tow rig it’s intended for.
Just wanted to see if you guys had any opinion on the idea or personal experience before I dive into parts. I’m already changing the perches on the rear axle to correct the pinion angle and move the axle back 1.5” to correct for the shackles flip.

That’s a lot of work for very little change. Been there done that and I chose to have ORD springs. It is a jarring feeling with any stock rear spring compared to a custom spring. For reference, the tailgate doesn’t sound like it fell off when you go over a speed bump.

If you're up for the work and the expenses you can't beat a softer spring and airbags especially if you plan on towing with it.
As for height I prefer the least amount of lift to clear the tires.
The lower the better
 
So LESS springs and will pull a goose neck if it’s low enough?? Seems counterintuitive.

I agree that, regardless of final lift height, custom springs is probably the best compromise.

Exactly what I’m goin for. I figure with the 35”s I should be fine with a 2-3” lift
 
My reply was primarily about going from 1 ton springs to 3/4 tons.
I didn’t think there was an option to stick with one ton springs. Is there a softer one ton that can be custom made? I just figured a lighter spring and mount the air bags for overload so it still rides nice when aired down.
 
Ideally if I had the cash I would link it front and rear and make it adjustable by air alone but I’m trying to finished the suspension on my k5 as well and I’m only one guy
