Dana 60 vs 14blt
- Thread starter MR.4x4
- Start date
I am assuming you are talking about a 14B full floater. From what I seen the 14BFF is stronger, I know it has a larger ring gear, I can say for a fact they are very strong, I have broken several 12 bolts in the past but since I put my 14BFF in I haven't had any more problems.
In most cases the 14 bolt FF will be stronger. Typically most of the rear D60's have 30 spline / 1.31" axles, where the 14 bolt FF has 30 spline / 1.5" axle. The 14 bolt FF also has a ring that that is almost an inch larger in diameter and the pinion stem is a fair amount thicker. In most cases the 14 bolt FF will also have larger drum brakes.
The drawback to the 14 bolt FF is that it is fat. It does have less ground clearance than the D60 which may or may no be an issue for you.

The 14-bolt is stronger. It is closer to a Dana 70 than to a Dana 60. /forums/images/icons/cool.gif

I agree the 14 bolt is a better comparison to a Dana 70.

12 bolt is a hair under 8.8" ring gear with C clips, so it's a step up from a 10 bolt (8.5"), but doesn't come close to the strength of a floating setup like the 14 or big Danas. I prefer the 14 over a Dana 60 or 70 because generally the GMs are easier to work on and set up and parts are usually cheaper although there currently are no manual locker options for a 14bFF, but you can get an ARB for a 60, if that makes any difference. /forums/images/icons/smile.gif
One thing I forgot to mention (that you may already know) was the gear ratio selection. The Dana axles have a much greater selection of available ratios than the 14 bolts (limited to 5.13). The trade off to gear selection though is that the locker cost for a Dana is a good bit higher.
The 12 bolt is a good rear end for a 1/2 ton, but unfortunately it is just that - a 1/2 rear end. With big tires it will not have the life span of the D60, D70 or 14 bolt axles.

What Harry said.....
The 14FF is stronger than the D60. It's also evenly matched to the D70 instead. /forums/images/icons/wink.gif

disk brakes conversions, rebuild kits, lockers, gears, bearings you name it. The 44s are pretty common so they are easy to get parts for, but the big ones with all the variations can be tricky to track down. With all the online sellers now, maybe they are getting closer in price to the GM stuff?

i will give you disc brakes because of the members of this site selling them for cheap though I am betting the cost would be exactly the same to do a run for a dana
and the detroit is just a lunch box for the 14ff but as that is the only thing available for it and the danas have almost everything under the sun that may or may not be a win if you want an ARB or something

Only if you consider 2004 to be "here shortly". /forums/images/icons/wink.gif I haven't seen an Ox Locker for a 14-bolt FF either. /forums/images/icons/mad.gif

Looks like I could be flat wrong on some of the parts. All I know is that when I decided to swap my front 10bolt for a 44, the gears and rebuild parts were more expensive for the 44 than the 10bolt would have been. Not a whole lot, but enough to make me think maybe it was a bad idea. I also toyed with the idea of swapping to a D60 front, but everything was a whole lot more expensive than the 44 stuff in addition to finding a good housing and I decided to save that for the next stage of the build up (whenever that might be). /forums/images/icons/smile.gif Maybe it was a bad comparison because there is no 14 bolt front end (except for custom ones) but with as cheap and readily available as the 14 bolts are, I wouldn't recommend going with a Dana rear, unless money is no object. Plus, I know by reputation that Dana 60s and 70s are strong but I know firsthand that 14 bolts are virtually bombproof. The one I used had around 200K miles on it and the gears were still in good shape whereas the D44 front off the same truck had to have everything replaced.
Whenever someone develops a good reliable manual locker for the 10.5" 14 bolt, I will be all over it. I've got an Ox locker in my D44 front (although I haven't even tested it out much) and was told that there are currently no plans to design one for the 10.5" 14bolt by both Drivetrain Direct and Oxtrax. They seem to be only interested in marketing to the jeepster crowd (their loss) so they are only designing for the smaller Dana axles that jeeps use. Hopefully they will come to their senses. /forums/images/icons/smile.gif

I have a D60 rear and the only real weakness is the small axleshafts. I've broken 2 so far, but they were under extreme conditions. Although, last time I checked, one of my shafts had slightly twisted splines. Unless you get disc brake brackets from a member of this forum, the brackets for a D60 are cheaper than for a 14FF, ($180 vs. $240), from TSM. I like the increased ground clearance I get over a 14FF, but I'd like to get a 35-spline conversion kit and a spool to make it almost bulletproof.
