SF 14 bolt

[tylerd13]

How will a semi floating 14 bolt hold up with a 37's and 4.27s locked.
Also how much wider are these axles than my stock w/t dana 44 axles.

[unclethumbtack]

I am no expert on sf 14 bolts but as far width I think it close. But for 37's it might be pushing it.

[tylerd13]

ok cool, would a Full Floating be wider, I don't think I wanna go ff becasue I don't wanna carry 2 spares or convert the front d44 to 8 lug.

a FF14 bolt would stand 37's right?

[unclethumbtack]

not that hard to convert the front. A 10 bolt is the same outers, dime a dozen.

[tylerd13]

what about convertin the 14 bolt to a 6 lug ( I already have rims and tires)

[unclethumbtack]

Converting to 6 lug is lots of work way more work that converting a 44 to 8 lug. You have a 77 Cherk right? Why not run 35's on your 44's until you have enough money to go up to a 14 bolt and a 60 front. Do you really want to do all that work just so you can run 37's? I am going to swap 14 rear and 60 front but after all that work I plan on running at least a 40 inch tire.

[tylerd13]

That would make more sence. But I'm tryin to get this done ASAP and money is a problem. I went looking for a dana 60 passenger drop couldn't find one, found a few driver drops but my junk yards around here wanted something like 700 for just the front. I already ordered heavy duty outer and inner shafts with 297x U-joint trying to beef up the 44s for 37's.

I don't want to run into a lot of carnige on the trail, and I don't want to baby it.. but I also don;t want to spend 700 plus gears and locker. for a d60
now I'm pissed because I will have almost 700 into my d44 after gears, shafts, locker.

In your opion/experince how reliable would 14bolt FF and d44 with upgraded shafts and u joins be with 37's. I havn't got drive shafts made yet (waiting on exact lift) so I could also upgrade the drive shaft ujoints for strength.

A d60 isn't out of the question because I can get my money back from parts for the d44 and sell the d44. but it would be way easyer to use the 44.

Sorry about all the questions I just want to get it done right.

I also got a buyer for my 35's and right now mickey thompson is having a 200 dollar mail in rebate so I can get 37's for almost the same price.

you can find factory 6-lug 14bolt rearends.GM used them in 88-98 light duty 3/4 ton trucks. They can be had in stock form for about $200. I found one here locally with 4.56's already in it for $400.

Shop around and be patient with the money you have.

You can find an 8-lug semifloat 14bolt for about $150 and convert your front Dana44 to 8lug for cheap.(converting Dana44's or corporate 10bolt's from 6 to 8-lug is a DIRECT bolt-in swap) Besides,by the time you take all of the outer parts off your Dana44 to put the new heavy duty axleshafts/u-joints in you can basically reassemble the Dana44 with 8-lug parts. That would make the project all come together ,for cheap.

and a semi-float 14bolt is plenty strong enough for up to 40" tires

If you got a Full Float 14bolt you can expect to run 44's or larger without strength issues

[tylerd13]

ok Thats what I'm going to do. Get a FF 14 bolt and run 37's on my d44 and If I'm breakin stuff I will upgrade to a d60 all the parts have good warrantys so If I do snap a shaft I can get a new one. and if I do go with a 60 I will move up to 40+" range. :cool:

Most Dana 60 fronts go for around $1000. You can find them cheaper, but not cheaper than $600 unless you get really lucky. Then add gears, lockers, steering arms, etc. You're going to spend a lot on a Dana 60, whether you want to or not. Check it out:

If you're going to run 8 lug rear, do the FF 14 bolt. A semi float 8 lug 14 bolt is useless. If you have to switch from 6 lug to 8 lug, you mine as well upgrade to an axle that can handle beef! The front is a different story. A lot of guys around here run baby jeeps with HD44's up front and FF14 out back, and break driveshafts and ujoints before breaking axle parts, but they're light weight vehicles compared to our monsters.

Just some things to think about.

Some of the later 88-98 K1500 Z71 trucks have the sf 14 bolt with 6 lug hubs as well. I've seen a few of them.

I know first hand that a SF 14 bolt holds up to 4.0 power and 37" tires.

This rig has a 4.0/904/D300, CUCV 60 front with/ 4.56s - Detroit E-Z, SF 14 bolt without rear brakes and a Detroit E-Z. It's on H2 rims and 37" red label Crawlers. The frame was stretched 7" in the front using Wagoneer springs.

That thing is like a spider on the rocks. :drivin:

[tylerd13]

Ya I plan on getting a Full floating 14 bolt, and converting the front to 8 lug.. and I will run it for now. But if guys with smaller jeeps are breakin stuff then I probably won't lock the front.

this is the best advice

I have a D44Hd and 14bolt combo on the sandgorgon with 38's. Same reason, D60 is pricey. If you put a good LSD in the front (I have true-trac) you will get good traction while limiting the stress on the 44. Go for it!

[unclethumbtack]

I don't think a SF 14 bolt is going to live very long running 40's.

[jeeping1974]

SF 14 bolt might be able to handle 37s if built right. you would be so much better off with a FF14 bolt.

you will regret not locking the front if you want to go places.

my HD44 lasted about 6 months with 39.5IROKS but i hammered on my junk pretty hard, i even broke a rear 60 shaft with my IROKS. get the FF 14bolt and run the hell out of your 44 till it blows. warranty the shaft if you can and sell that thing so you can get a 60 up front.

go with a limited slip like some of the above mentioned ones, i prefer a lock right my self and you should be golden if you can use the skinny pedal correctly
