1979 2500HD, what axles?
« on: July 17, 2004, 08:07:00 PM »
My buddy just bought a '79 2500HD longbed. Its fulltime 4-wheel drive. We're just wondering what axles it has. If anyone knows, plz reply.

BTW, he got a sweet 5ton Warn winch with the truck for almost nothing, it was a good deal.

Thanks in advance for any responses. :evil

Is it a 79 K20, or is it a 89K2500, or a 99K2500HD?

If it's a 79 K20; You will have a 14bolt gm corporate full floater rear and you will probably have a gm 10 bolt front.

If it's a 89 K2500; You will have a 14bolt gm corporate semi floater rear with IFS.

If it's a 99K2500HD; You will have a 14bolt gm corporate full floater rear with IFS.

As far as your differential carrier in the IFS applications; I don't know which is which.
