    What do you mean they are 3/4 ton and have 1 ton stuff? If you mean a 14b in a 3/4 ton its not a 1 ton 14b. Has a smaller ring gear and its a semil float instead of full float axle.

    If that wasn't what you were talking about then I have no idea.

    No that was along the lines of what I was talking about. I know some of them were 14sf/d44 setups instead of a 14ff/d60 like a one ton but basically I just wanted to know what a "heavy" half ton was.

    A heavy half was the half ton truck with a SF 14bolt. They were 3/4ton light duty if you will. And as far as 3/4 ton 14 bolts not the same as 1 ton that is just incorrect. The 14FF was offered in a 3/4 ton and to my knowledge was a more available option than the 14SF.

    I know nothing about "heavy" half tons but it just so happens a guy mentioned those trucks to me just the other day. He said they had a 12 bolt?????? I have no idea if that's correct. I am still learning all this stuff and I've heard people talk 10 bolts and 14 bolts but never a 12.

    Only 12 bolts I have seen are in the older half ton pickups and blazers but never heard then refered to as a heavy half. I always though 12 bolts were before they had a 10 bolt rear:dunno: . I have always heard of heavy half as a pickup with a 14SF. I cannot see what lug this truck is but they did have 6 lug 14SF.

    you sure? Because When I asked that question a LONG time ago it was explained to me as 14sf 3/4 14ff 1 ton never heard of a 14ff 3/4 ton.

    All the heavy halfs I have seen were 5 lug 2wd or 6 lug 4wd this is of course prior to the new stuff in the late 80's 90's and currently .

    I am talking about the real trucks prior to losing the SFA :thumb:

    Heavy halfs were designed to "outsmart the government". Something to do with gvwr and emissions.

    All the 70's 3/4 tons had 14bff's to my knowledge. I didn't think the 14sf came along until the early 80's. I have seen plenty of 14bff's that were 3/4 ton, those are the ones that swap easily into your half ton, cause they had the same perch width as a 1/2 ton. The 1-ton 14bff's have a different perch width, and have to be cut off and relocated in order to work on a 1/2 ton. So there's definitely a TON of 3/4 ton 14bff's out there.

    Yep I have a 3/4 ton 10.5" ring gear 14FF with a 2 piece carrier with a drop in Detroit No spin. A 14FF is 10.5 and a 14SF is a 9.5:D . All 14FF are the same except for spring pad width and shock location. Well that and the newer ones have a slide on drums.

    What I was always told was
    Half tons have 305s
    Heavy Halfs have 350s


    The 14SF was after the body style changed in 88 and the 14sf and 14ff were jocketed between 2500s not 1500s as far as I know

    The 14SF came out in like 79 as I have seen some old CKs with 14SFs in them. In reality it is not worth getting Avery over J/K:D .

    basically 1/2 ton tow package probably a 350
