10.25, 60 or 70 rear

My choice, The Beef, D70 for the 35 spline shafts and gear ratio selection all the way to 7.17. Plenty of locker options available, the carrier makes the D60 carrier look small, never thought I'd say that.
 
No fawking way I'd touch a 10.25.

Can't beat the 14b for cost-effectiveness and overall strength. 70U is another solid choice, but it really depends on what you're looking to do.
 
I've got a D70 1SU in the rear thats being converted for rear steer. Its what I had laying around, but its a nice strong, beefy axle. I'm glad I went with that versus the D60 I had laying around...

It does have 35 splines stock, I liked that feature.

yeah we dont know what exactly your application is here but id go with the 70 hands down. its stronger versus the 60 and more applicable than the 10.25. like saf-t scissors said another option is the 14bolt which is stronger than a 60 but not a 70 and with less gearing and locker options plus you gotta shave the hell out of it for ground clearance.

Fawk ground clearance, if you got enough horsepower you can just slap a pinion guard and diff cage on it and drag her all over the place. That or just hit the gas hard enough to clear the obsticle :driver:

Seriously thou for the cost and ease to find vrs strength, 14 bolt wins my vote
 
well my truck is a pathfinder and i'd like to run 38s-39.5s. I want to run lower gears than 5.13s so the 14bt is not an option. Im afraid that with the 70 its going to ruin the clearance underneath the diff unless I run something like 42s or cut some out of it...
 
While the 70 is 35 spline, the 14 bolt 31 spline is a heavier axle. The 14 bolt gives you an extra set of pinion bearings. The draw back is as stated, gear selection. Don't let ground clearance scare you. HCORE in Boone can give about the same clearance from a 14 bolt as you would get from a Dana 44. I don't know, but he may be able to do the same with a Dana 70.
 
10.25, 60 or 70 rear What would you use....

Like he mentioned in the 1st post, he's NOT thinking 14 bolt! What's with the 14 bolt answers? He want's lower gears than they can offer. Shark, the 70 can be shaved quite a bit I know. I'm looking into doing mine and with the cover off there is a LOT of material that looks like it can be removed. I've seen a few sites on the web where they have cut almost an inch. Also, I think the 60 would hold up fine with 38-39.5 tires. I've been running 42s and 44s for a year in a D60 with no problems but mine is a pretty liteweight rig.
 
a 70 is only hangs 1/2" lower than a 60 they look basically the same. a 70 is way stronger and more versatile than a 14bolt. do your homework kids. you can find 70's in junkyards all day long for cheap
 
like the tv commercial says "the more you know."

Some Specifications and Facts on the 14 Bolt:

Max gearing is 5.13:1 i think a 5.38 is gonna be available?
Very limited locker selection
1.5 30 Spline Shafts
Max Torque Rating: 6242 Lb-Ft of Torque
Cast Iron Housing
Some Specifications on the Dana 70:

Max gearing is a massive 7.17:1
Excellent Locker Selection
1.5†35 Spline Shafts
Max Torque Rating: 8,000 lb-ft or 8,800 lb-ft for the HD
Nodular Iron Housing
The two most significant of those are the gearing and torque ratings. You can gear a Dana 70 45% higher, and it is about 30% stronger than a 14 Bolt. Also to be noted is the different housings, nodular iron is much stronger (Ford fans know of the famed N marking on a 9†housing). It is also easier to weld to if you are doing an upper 4 link mount on the housing.
 
Why do people always say the 14 bolt has a "limited" locker selection?

Spool? Yes.
ARB? Yes.
Detroit? Costs 1/2 what a D70 one does.

Let's not forget that the D70 uses the same 29 spline pinion as the D60. I don't care what the factory torque ratings are, broken pinions suck.

14 bolt pinion shaft doesn't neck down like the Dana axles do.

Edit: and don't forget that it only takes about 5 minutes to do gear setup on a 14 bolt. You should be putting oil back in it within 20 minutes of assembling the pinion support. ;)
 
Back the the question ---

A dana 60 rear has about a 1" axle shaft and when I boke it I upgraded to a Dana 70. It's not even in the same league as the others.

Dana 70, 14 bolt, and sterling 10.25 are all similar with about 1.5" axle shaft.

The D70 is definately the best. The 14 bolt and sterling are similar as they both have weak points. Plenty of people run sterlings and 14 bolts for 44" and up.
 
I vote save some money and go with a 14 bolt. The D70U has better clearance but you really can't shave as much off of as you can a 14b. I think all the engineering that went into 14 bolts is just cool... side adjusters so you don't have to use shims when setting up gears, removable pinion housing, pinion support bearing, two piece carrier, the list goes on. If you do get the D70 make sure you get the right one, some are 23 spline and are impossible to find aftermarket gears or lockers for.

If you're worried about gear selection I think 5.38's are out now, or will be soon. Or just put some reduction gears in the transfer case and call it good.
 
oh yea... and WELD THE TUBES on the 14 bolt! Rosette welds are not your friend. :flipoff2:

read the post biotch!!! 5.38s are available but are not strong... they are easily breakable and that is the last thing I need. Please no more about 14blts in this thread! It is not an option...
Most of the people who have bought the 5.38s retruned then.. here is a picture of why...

There's little appreciable difference between 5.13s and 5.38s. Not enough of one to be the deciding factor in a build. If you're worried about whether you spin 2400rpm at 65 or 2500rpm, then possibly.

You said the "last thing you need" is a broken pinion.... so the D60 and D70 and 10.25 are all out. Looks like you're shopping for an Eaton, 14 bolt, D80 or Rockwell. :flipoff2:

give me a break. Im not going to knowing buy some gears that have been f-ed up by about everyone who has ran them.That is asking for a broken pinion. You don't hear about people breaking them as much on 60s or 70s.. at least I don't. I have done quite a bit of research and just wanted to get some more opinions. Elliott, as soon as you earn 1200 bucks and buy me those transfercase gears I'll do that. If you read the thread I wanted to step up to 38-39.5s and being that the pathfinder stock comes with 4.63s, 5.13s are not going to turn those tires on the road and I do not have a tow rig as this current moment so that ratio is one Im not going to choose. I ran 5.13s on my frontier with 35s and it wasn't enough. I wanted to go a lot lower than 5.38s anyway. Thanks for the people who have given quality opinions...
 
thought they offered advise for and against, and offered up an alternative, and this isn't quality ?

guess I missed something.

Im not trying to be a dick. I apoligize if I come off that way. Well quality but information I already knew and that would do me no good. If the nissan gear wasnt so low already it would be a perfect option, but being that it is much lower than your jeep, chevy, or ford it just wouldnt work for me as a street driven rig. If I had a tow rig and trailer then yes, I could consider just doing 5.13s and some t-case gears but unfortunately that is not an option right now. So advise for an against the 14blt won't do me any good. I do believe I will start looking for a dana 70 and just shave a tad off the bottom.
