What springs for ride comfort?
1997 F250. 7.3. D60 swapped.
Currently have ttb50 springs under it and they need to go.
I want the nicest smoothest ride ever. I don't want to lift my truck at all, unless it's VERY minimal to gain a lot of comfort.
Truck is normally towing 5-8k.
What front springs should I buy? Should I buy bilsteins for all around? Should I replace the rear springs with lighter duty springs and put bags back there that I can juice up to hold the weight when I'm towing? I read something about flipping a shackle?
Too many options and I'd like suggestions before I start spending. Thanks!

if I could pull a 6k trailer with a Cadillac and not get pulled over I most likely would.

Are you measuring a stock F350 shock at collapsed and extended lengths and then buying whatever is closest to that?

If you want the best ride you need a pmf rsk and use u code SD springs. That is MY plan in the future. I have 5125 bilsteins. You will have to measure your length and look at their lengths and get the correct one. Remember the 70% rule. At ride height the shock should be 70% extended. Also 5125 use a 1/2" bolt end. I drilled the mounts and got new bolts. With an rsk,5125s on worn out stock springs she is far from my wife's 2010 Lincoln town car... Its much better than when I bought it tho. I'm going to switch my sky kit for pmf and replace these old springs hopefully sooner than later.

fordman67 is spot on.
The TTB leafs are much stiffer than the F350 leafs...just this change will help...a lot.
Replacing the rear leafs with SD leafs, B codes, makes a lot of improvement too. This requires a hole slightly enlarged, otherwise a direct bolt in.
The PMF RSK is (in my opinion) the best bolt in RSK. I am going a slightly more fab involved method though.
The SD U codes leafs are almost the softest available. Mine settled to be almost perfectly flat. Very nice ride.
The selection of shocks is important. A brand name and shock series are not detailed enough. The rear shock most people use did not have enough rebound dampening and the rear leaf would give a kick after the bump. i went with a shock that had sufficient rebound dampening but with it came an increase in compression...which feels harsh. I would have been money ahead to buy shocks with a custom valving.

Tires play a role as well. I used a stock set of f350 front springs with my D60 conversion and Monroe gas-adjust shocks and the ride improved considerably. About 10k miles later it was time for new tires. I had a set of ATs but decided to go with a more aggressive pattern so I went with Cooper STT Pros. I was surprised to find that they were not any louder on the highway and they changed the ride as much as the springs did. I loaded heavy yesterday (19,750lbs gross) and they handled the weight well and look great too.

I think the front holes need to be drilled 1/16" larger and possibly the rear shackle.
Junior at atssprings dot com sends a new front front bolt that is a little larger. And then the front bolt gets moved to the rear.
It's been a while...
