im a little confused

ok now this whole time iv been thinking that the # increase with the axles means a stronger axle. ex: dana 35 is weaker then a 44. ok well my question is, i just read that the dana 30 should work with up to 37 inch tires and the 35s will work with 33s at the biggest. ??????? huh was this person confused or no? cuz if thats true i may just get a super 35 kit and then throw lockers on them both and get my 35s and forget my dana 44s, that would be fine with me. that configuration sound like it would work with fairly agressive offroading if i stay off the stupid pedal???

Re: im a little confused

It all depends how much stupid pedal you use..

Strength wise, 30-35-44-60-70-80 As far as I know..

Sure there are people who break the stock axles.. but MOST of the people preaching "Dana 30/35 combo will break" have never broken, nor seen one break.

Everyone you talk to will say something different.. I'm of the mind that when I see one break because buddy wtih the 35" tires gently pulls out of the stopsign I will say it's crap.. but so far, I've seen 35" boggers on the 30/35 combo and the guy with that is just sensible.

Don't bounce your truck, don't pull backwards.. some simple rules will save you parts.

But... agreed the big benifit of a 44 or 60 is the full floater.. drive home in front wheel drive.. no worry of the wheel falling off

Re: im a little confused

Man, I have a Dana 25 up front with a locker and I think that if it has lasted 52 years it should last with me

I may trade up one day to a 44, the guys are right sensible driving will go a long way

I will agree on one thing though 37's on a 30 does seem crazy and seeing your axle slide out the side in your rear view mirror at 55 is a little scary.

Re: im a little confused

The Dana axles are generally stronger as the numbers go up, but there more to it than that alone. Ring and pinion size increases in the progression that infernox has set out, but depending on the donor, the number of splines on the internal axle and it's diameter will vary, as will the thickness and diameter of the outer axle tube. Within the axle series, such as a dana 44, there are other differences such as older 2 piece axles that are splined onto a hub at the outer ends and are weaker. As well, on front end, some dana 30's use the older small u joints like cj's did, and others have the larger 297x joints and are more desirable. Some front ends have axle disconnects that are troublesome as well.

Bottom line: If you find yourself an axle that you would like to swap in, tell us about it and someone will be able to advise you whether it's a good swap or not.

Re: im a little confused

The reason the dana 30 is "rated" for a bigger tire than the 35 is because the 30 is used in the front and the 35 is used in the rear. The front will usually have less load on it than the rear will. In climbing, the front has less weight/traction than the rear.

Re: im a little confused

The model # has nothing to do with it's strength...the D20 is better than a 30, 35 and likely a 44.

The D30 is a decent medium duty axle.

The D35 is an excellent boat anchor, think I'm kidding? look at this

Re: im a little confused

Might I STRONGLY suggest you do not waste ANY money on the D35 axle. It is merely a boat anchor, it just doesn't know it yet. The D30 is an "ok" axle, and can take a bit more abuse than the D35. If you think you need the strength, step up to a D44 or 8.8 in the rear. Like been said before, you can polish a turd, but in the end, it's still a turd, only shinier.
