    I started my new job raking concrete and part time trench monkey so I will finally have the cash to get a 14bff under my rig and maybe an 8 lug d44. What rig would be best to pull these from? I have an 88 1/2 ton k5 silverado with 10b's front and rear.

    Also i will be looking for a d60 somewhere in the scrap and need to know what rigs they came on.

    Any K20 from 1973 to 1987 will work.

    Don't worry about the D60, you won't find one at a junk yard. Even if you did it will be out of your price range.

    3/4 ton 14BFF's are a direct bolt in. 10b's are all the same, thats obvious. 44's are nearly bolt in. I think brake lines or something need to be changed, not sure, never was interested in 44's.

    the 3/4 ton are stright bolt in. the 1 tons have the spring perches spaced differently. wider out i think. you would have to cut and weld the spring perches if you used a 1 ton axle.

    I think around 1980 they started putting 14BSF in the K20s so make sure you specify the FF.

    The only real difference btw the 3/4 and one ton 14BFF is the width of the spring perches.

    Aren't the Dana 44's from 1973 to around 1976 the ones with a smaller axle tube diameter meaning he will also need new spring plates? The early Dana 44's also have a smaller inner bearing.

    The spring perches on a tonner are like 2 1/2" narrower than a 3/4 ton so you'll have to cut 'em off and redo them. Not hard. Also, the shock mounts are different so if you buy one out of a 1 ton you'll need new shock mounts.

    1/2 and 3/4 trucks have a perch width of 42", 1 tons have a 40" width, IIRC.

    Moral of the story, out of the dozens of 14BFF's at every yard....just get a 3/4 ton version! :D

    Like mentioned above , the early D44's were slightly different in the hubs or something, but will still work. I would look for an 8 lug 10B myself.

    Maybe You could give an answer instead of being rude. Why not just say.
    D60's came in 77-87 1 tons and 88-91 crew cabs, but they can be pricey.
    Just cause the kid is starting a new job does not mean that He wont be able to afford a D60 later down the road.

    I've gotten used to it... :cool1:


    I'm thinking about a parts truck.... i've seen some on ebay for 1k that come with a d60 and 14bff but I'd hate to pay shipping on a 6000 lb truck.

    For now i think i'll keep the 10b up front but if i could find a d60 for 600 i'd buy it.

    I plan to put a 2" body lift on her, clock the tcase, fab a full skidplate like estaban's, and then get some 36x12.50 tsl's or 13.50 iroks.

    for now i guess the 10b will hold up fine but it would be nice to have 3/4 ton brakes front and back.

    Just go to the junk yard and come up with a 3/4 14BFF and 44/10B 8 lugger with matching gears. You don't need a D60 anyway for a smaller, light 36x13.50 tire. I've got considerably more torque than your '88 with grippier 35x16 boggers with a front 10B and have done about everything but rocks without a single part breaking up front. What do you have to loose? You grab a 10B for cheap and you break something, no biggie. If you start breaking frequently then I would say a 60 should be on your mind, but I doubt you'll ever break a thing, especially if you drive with a brain and don't hammer on it with the wheels cocked, on a rock, the usuall. Just use some common sence and you should be fine.

    I personally think D60's are over rated for our smaller K5's. YOu would be pretty much in the same catagory as me with 36" Iroks and your motor. A little power, decent rubber, average wheeling, but not over what a 44/10 can handle. ;)
