One ton will have floating axles, Meaning, bolted in from the sides of the drums. Semi floating are c-clipped inside the diff.

3/4 tons are full floating as well, nick is talking about the pregnant 10 bolt thing

the spring perches are narrower on a one ton then a 3/4 ton or 1/2 ton

3/4 ton c14's are both semi and full floaters, depending on the gvw of the truck. The one ton axles have a 3" wide shoe's on them, where the 3/4's are 2 or 2.5 wide. The ff 3/4's are just fine for wheeling with, just the smaller brakes. It's the semifloating ones that are crap. They work, but for the added weight, your loosing on the trade.

dont the 3/4t have the 11'' drums and the 1tons have the 13'' drums? i might be wrong, my 83 k2500 has the 13'' drums though.

If it's a full floater it should have the 13" drums but they are narrower than the 1 ton axles, also with the 13" drums.

by narrow on the 1t you mean dualies, i would assume that 3/4t and 1t SRW's would have the same re-end?

Assuming both are full-floating and SRW....

1-ton drums are 13x3.5", and backing plates have more dish to them; spring spacing is 40.5" with pass. shock angled backwards, driver's shock angled forwards.

3/4-ton has either 11x2.5 or 13x2.5" drums; flatter backing plates, 42.5" spring spacing. Shock stagger is opposite 1-ton.
