Hey, that isn't fair......or unless you have some sweet parking lot fab session going on with the Jimmy
Did you just say IFS because you didn't anyone would know what a TTB is?
My dd has aN AAM 9.25 front and a AAM 10.5 rear... Burb has a d60 and a 14bff. I think that 10 bolts under anything more than 5k pounds is a joke.

60 & 14 here. The 14 was already in the truck it's a 81 3/4ton. P.O. tore the 10b up and fixed it then I busted a shaft a 60 seemed more economical than a ten in parts repairs and down time.

I have both
Horton has tons,
Jimmy has 10 bolts. Looking for a 6 lug SF right now. I even had a set of tons for the Jimmy, but thats not the direction I am going with it.
10 bolts are fine if you aren't breaking them. Once you start to break its time to upgrade.
Shoot I ran 38s on a 10 bolt front ( unlocked) for 2 years. Then I found my set of tons.
X2 on this.
I ran a set of factory, 8 lug 10 / 14bsf under my 86' GMC longed with a built 400ci and never broke anything...swapped them under my K5 and ran em for another year or so with no issues. I finally found a deal on a set of tons and could finally rest easy wheeling with the family, knowing at least my axles wouldn't send us hiking home.
On the other hand, I did have a 94' GMC IFS w/ a 10 rear and I shredded the ring gear teeth running 35's. It may have been a set up problem from the factory...dunno. I also busted the CV half shafts 3 times. This is why I am running a straight axle rig for wheeling now.
Nope. Just compensating. Everybody is post up big axles. So I figured I would go bigger. I did wheel it across a dirt lot the other day.
Well, I'd like to say so, but the plain fact of the matter is, it was almost midnight when I posted, I had been up since 4 in the morning, and I could not remember the term Twin Traction Beam.............
But I could remember Independent Front Suspension.......
I'm running locked 10 bolts front & rear.
...with 2 spare rear shafts in the back.
I'll be upgrading next year.

I'm running a d60/14bff in the blazer and I've grenaded the passenger inner/outer 35 spline... But that's what happens with 44s and mud that's 5 feet deep...
I don't do a lot of off pavement stuff. Mostly trails when I was in the Army going to training areas.
I have 35s and I tow a 4600 lb boat. With the factory 3.73s it was a dog on the stock 350 and I knew I needed to re-gear the thing.
Rather then pay someone to do the gearing front and rear which I'm sure would have ran near 2k I went and got a donor 1028 for 1200 bucks.
In hind-sight I wish I would have just re-geared the 10b/14sff now. I've still got the d60 in the shop torn down waiting for me to finish it.

I dont know about the rocks n stuff but around here guys running 38's and bigger with LOTS of hp all run d44's in the front of their mud trucks. I mentioned the 60 to a few and none of them wanted one due to weight. they say a 44 can be built just as tuff
I'm sure its a lot more money. but maybe not if you already have one to build

It's basically the same here, a "decent" 60 here goes for 800 and up. Usually way up. On top of that the rebuild, regear, locker, hubs, bearings. They can get pricey. It is a stronger axle all in all, just a bit expensive for some.

I wheeled a D44front, and front 10bolt for years with no issues granted they were open. I just came across a D60 for 100 bucks and had to take it.

Well to start, this is a great forum and i've learned so much with interaction with some of the knowledgeable people on here. I currently have an 89' k5 that has your typical suspension mods (shackle flip in rear, springs and zero rate, and etc etc) and even have a cv rear shaft. I currently run 37's on the 10 bolts. I do have a 14sf in my garage that i havnt got around to messing with yet, but plan to when funds are right along with some regearing.
My question is, does EVERYONE really have the 14ff/d60??? I know its a bullet proof combo, but damn, everyone and their moma seems to have them. My current 10bolts have a little $$ in them and have been fine (knock on wood) for a long time. I mean, if u rock crawl every weekend thats one thing, but for normal driving and occasional dirt/mud offroad, is it really needed?? Maybe its different for me since i live in eastern North Carolina, but is there anyone still running 10 bolts or just 14sf??
Yes, most people do after a while....
Save your money on the 14sf gear change and start looking and wheeling and dealing for a 60/14 combo. They pop up on craigslist from time to time at a decent price. Or find a donor truck with them on already. Pretty easy in the NW to do.
