1/2 ton to 3/4 ton suspension

I'm converting my 1/2 ton suspension over to 3/4 ton suspension but I have a few questions;
Rear: Are the 1/2 ton and 3/4 ton trailing arms the same?
Front: Is the only difference in front suspensions the upper and lower a-arms and spindles?
Thanx in advance
Dano

Re: 1/2 ton to 3/4 ton suspension

The trailing arms are exactly the same.

On the front, you are right about the A arms, spindles, ball joints, etc. Plus the idler arms are different, too. But it's an easy swap, and I've done it in the reverse direction a few times with no hassles.

The calipers are the same too, I think.

good luck, and take lots of pictures!

3/4 ton trailing arms are plated top and bottom. At least the ones I've seen have been.

Yep, the trailing arms on my '67 3/4 ton are plated top and bottom.

The are the same for that as best as I can tell.

Could be. I was thinking the length and bolt patterns and such. I've never actually taken them off a truck. Just swapped rear ends off what was there already. Sorry for the confusion...

They are identical other than the plating that was added to make them stronger.
