Alright, what the... F-250 vs. F-350 front leafs

[NotMatt]

Alright... so I'm swapping a TTB out of an '89 F-250 into my '90 F-350 so I can sell it (I'm keeping the 60). Apparently the springs are different. I have the stock TTB brackets bolted in, and with the two sides of the TTB bolted up and the rig sitting with weight on the springs, both sides are well beyond "droop" still.

So an FYI, even though I was told the springs are the same, they aren't... F-350 springs have much more arch to them.

So, tonight I'm going to measure and see what I can do... both leafs have a 1/2" "lift block" leaf attached to the bottom of them, I can take that out, but it doesn't look like it will net me enough of a difference to make the TTB assembly ride right..

My other option is to dig out the TTB brackets that the guy gave me that are for a lift, and measure and see if things will line up that way... which is probably my better option, since I want the truck to ride level, not raked out and nose low.

I figure this might be helpful info for anyone doing the same project as me down the road. Those kingpin HP 60's are overkill for a "tow rig", and can be put to much better use under a Jeep. :awesomework:

You're selling it right?...Just put in a set of air shocks in the rear...Tell the new owner the shocks are there to raise the rear. No reason to be dishonest.

You didn't state if this was a diesel or not.

But generally for the diesels, the F250 have a negitive arch, and the F350 have a slight positve arch.

I plan on doing the same with mine, swapping in the TTB( and saving my 60) , if and when I sell it.

This is a 460 gasser.

Anyway, I dug out the lifted TTB mounts that the guy who gave me the TTB setup threw in with the whole deal. I think I can make it work like this. The holes might need to be re-drilled, but the lifted mounts have lots of room for that, so we'll see how far other way they throw the camber tonight

Definitely good info Matt.....I thought they were the same as well, but now I know!!!

just curious but why didnt you go with a dana 44 solid axle instead of dealing with that TTB bs

Because the TTB was free, an F-250 8 lug D44 is not... I bought this truck for $750 bucks, made it into a good runner and drove it for a while... now that I have a new one, I'm just swapping the TTB in so I can sell the truck as a whole good runner.

My original plan was to go with a solid D44... in fact, I went to Yakima to buy one, and it turned out the guy also had a TTB setup sitting there that he gave me. I ended up buying the D44 anyway, and selling it to my brother for his comanche for what I paid for it.

Also, the 8 lug D44 from early F-250's is not a "direct" swap, the spring perches have to be moved and the drag link needs to be shortened because the early trucks had narrower frame rails, and I'm sure there would be more little "problems" to overcome. The TTB is a direct swap, IF you have the right springs. Everything bolts up.

That answered my question
