    Im looking at these axlesthat are currently under an '84 3/4 ton with a 6.2 diesel eng.

    Here is the front axle that I'm having trouble figuring out what it is.

    Here is the rear that I think is a 9 1/2" 14 bolt corporate.

    I've used the axle identification chart which is how I come to the conclusion for the rear axle but cant figure out the front. /forums/images/graemlins/confused.gif

    So are these worth a darn compared to a D44/12bolt rear?

    the rear 14bs/f is stronger than the 12 bolt, but the 44 and 10 bolt front are very similar in strength. just more affter market parts for the 44.

    That 3/4 ton stuff should be an 8bolt pattern, shouldn't it? My '80 K25 had a Corp 10 up front and a 14FF rear with 8bolt pattern. I thought 6bolts only came on 1/2tons.

    yeah the axle in the pics are all 8 lug. The 12 bolt/D44 are 6 lug stock units that are currently on my '77 blazer. I was thinking I might swap these 3/4 ton axles in if they were better. /forums/images/graemlins/confused.gif

    If I were you, I would keep what I have. IMO, for the money you will spend on thay swap, including the new 8 lug rims, you will not be provided with a proportionate upgrade in overall durability. Some of the most hardcore wheelers on here (Marv Springer comes to mind) run a similar setup to what you already have. I would either upgrade your current setup or, if you have been bitten by the bigger is better bug (I certainly have), keep looking for the 1-ton stuff. /forums/images/graemlins/smile.gif Just my .02.

    Whoops!! Everyone thinks the pics and the 8-lug stuff is YOUR truck, but those are the axles he's looking at!!! Yes, buy them and swap them in. That 14 bolt rear is stronger that your 12 bolt and the front 10 bolt will have larger brakes. This will set you up to run larger tires. If you don't rock crawl, these can handle 35" tires. The rear axle I'd stick with up to 38's. The C-clips can suck, but at least you will be 8 lug so you can buy a 14 bolt Full Floater later.

    I dont rock crawl. I'm on the forever quest of creating the most badass hunting rig known to man. (but if there are some rocks between me and where the deer and antelope are playing, well....) I've got an '84 jimmy parked and ready to tear down.

    As for these axles, the rear 14bsf in the pic, will it have any type of gov lock or limited slip as I now have in my 12bolt rear? I plan on an air locker in front. What will the differance be with an air locker in the 10 bolt VS the D44? /forums/images/graemlins/confused.gif
