what should i be paying for a good rebuildable set of 3/4 ton chevy axels?
I bought a 10bolt front, open, 3.73 and 14Bff, limited slip, 3.73 for $250.
It depends a lot on condition, ratio, and what axles you are are actually looking for.
73-79 have d44/14bff
80-87 have 10b/14bsf
Make sure it has a gear ratio you like because if you have to regear, it will be $1000 for both.
I paid $600.00 (US) for my 3/4 ton Dana 44 and 14 bolt with 3.73's plus a SM465 and NP205. Both axles were open and not in need of rebuilding. I have 40,000 miles on the drivetrain already and no problems yet.
Oh yeah I got the front and rear driveshafts too
I paid $25 for my 8 lug 44.... But that was just luck.
Usually you see them for about $75 to $200 ea. depending on where and who you buy it from.

Doesn't the 80-87 3/4 ton trucks have 14 bolt FF axles? I think the "Heavy Halfs" and some later 3/4 Subs came with SF 14 bolts. Just trying to give some more options to smp if he is looking for a FF 14.
SMP> Do you have anymore pics of your rig, cause I just love that thing! If you do...........e-mail them to me!
Blazin' in TEXAS!
The 80-87 k20s came with the 14bolt SEMI-floating. Probably depending on option, you could get a FF, but all the k20s from these years that I've seen have had 14 bolt SF (and usually but not always Corp 10 bolt front.)
By the way, there is nothing really wrong with a 14B SF. It's still way stronger than a 10 or 12 bolt, the ring gear is 9.5" I believe. People will always jump up and shout "c-clip", which is true, but do you think most people can break a 14b SF?
I personally went for the FF because I got a good deal on mine, and it's true that i'll probably never have to worry about breaking it.....ever....for any reason. Lol. Esp. with the measly 33's I have on there now.
My old 80 GMC 3/4 ton and 2 friends with 3/4's (84 and 87) all came with full floats. Maybe we all had a HD towing option or maybe it's just a Texas thing...
Oh well, I guess the main thing is to check the axle to see what you really have. I do agree that a 14 SF will be strong enough to handle almost anything. Here in Denver, the FF axles seam to be easier to find and cheaper. For what I run, I prefer the FF.
All of the 3/4 tons I have seen have had FF rears in them all ! Subs are the only thing I have ever seen the SF !!

Do SF's come with 6 lugs or 8... or both?
BLAZE IT UP!!!
Both. I think the 6 lug versions are harder to find. If you do find one that's 88 or newer (truck), you will have to move the perches.
i have found alot of sf on 3/4 2wd. i was also wondering if a d60 front on a dodge 1ton would work on a k5?
My 82 K20 4x4 burb is a 350 gass Th400 208 TC
It is 8,600 GVW to escape the cat blues and has the trailer package rated at 12,000 GCW
came factory with 14 bolt semi floater in rear and 10 bolt in front (with 4 shocks in front).
8 lug 16" steel wheels
One question is their any way thru the axle codes to tell the ratio and if open or limited slips when looking at 14 SF or FF at the salvage yards.
Most Dodge Dana 60's are 1/2" wider. With narrow springs like BDS, you could make a Dodge D60 work.
Hey turbo, I don't know about codes and such to tell you what the ratio is or if it is a posi or not, but I would strongly recommend pulling the cover off of any bone yard diff. That way you can have a good look at the condition of what your buying as well as answering the ratio/posi/open question.
I paid $550 for my 14FF and Dana44 From Zackoff.Both needed completely rebuilt,But they did come with stock rims.The $550 did not include the $130 in gas and $110 ticket my bro got in Indy.Which i paid for cause he was the only one willing to let me use the truck for the trip.So..about $800 just to get them home.I dont even want to go into what it cost to rebuild these things.....=) later
