what smooths out the ride is the use of SD springs...unfortuneatly on the stock F-250 front axle (D50 TTB) they require a stiffer spring pack so I dont think the SD springs would work...Just a shackle reversal without a D60 monobeam swap/SD springs; you will gain lift but not smooth the ride IMO.

I don't remember anybody doing it that way, but if you boxed the front of the frame to move the shackle forward, I don't see why you couldn't do it.
Did you also swap to the springs when you did the swap? The ttb springs are a lot stiffer then the monobeam axle springs.
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: chillmastr</div><div class="ubbcode-body">I have Super Duty springs but no D60 are you sure SD leaf springs wont work with the TTB Axel </div></div>
which question are you repling too?
the TTB springs are stiffer then the monobeam axle springs, so everybody says that they would be too soft.
I do not have the TTB so I can't say for sure.
Going back to your op, yes it has been done, you can put the rs kit on a ttb, you would need to also use or make ttb center drop down brackets in addition to the rs kit.
Sorry for the confusion, I think you have already ansewered my question. I was wounderin if you could use SD springs and a rs kit with the ttb axel and drop down brackets.
From what I was told when I was going to do the same thing the RSK allows for the SD springs. And you can use it on the TTB as long as you use drop brackets to adjust the offset of the lift.
And from what I hear the ride is alot smother not sure if it's because the shackles now on the rear of the front spring or because the f-250 springs in general.
BTW sorry for hijacking your thread earlier, It's kinda the same question I was going to ask but for the Dana 60 instead.

What makes the ride better is the SD springs..they are longer and the axel is almost centered on the spring. The shackel relocation without SD springs is a little improvement over stock.

Mr. Cary not to highjack his thread again but I can use SD without the RSK correct? I'm almost thinking about getting another truck because it's riding so rough now after the dana 60 conversion. Was hoping all I had to do was get a 6" lift SD springs but will they be any better?

No problem highjacking its kinda cool im learning two things at once. I think i m going to try to do the RSK with SD springs and the TTB axel. If it dosent work ill just put the stock springs back on. I know i will have to ajust for the length of the springs. It seem no one knows for sure if it will work so ill give it a try and let every onr know how it turns out.

You need to install a RS kit for 2 reasons..1 is to get the shackels in the correct spot. 2nd is since you must move the front shackel forward 4"aprox to install SD springs ya just as well do it correct...see #1
A few choices...A RS kit and SD X code springs will ride better than even Donahoe 6" springs but you would have to use a 4"+ RS kit. Best ride is with V code SD springs with a 5'+ RS kit.
Next best would be a Shannon RS mod with Donahoe 6" springs. Both will require properly valved Bilsteins...not the valving that Bilstein or Donahoe recommends but correct anyway IMO.

I was wondering the same thing. I've noticed the way Cary has worded this lately... properly valved Bilsteins. Cary????
