high strength axles

im still determined to run 35s lol. If I replace my crappy stock 27 spline d35 axles with the alloy usa 30 spline kit will this be enough to handle the 35's?

also does anyone have experience installing these? if so how hard is it..

It would probably be cheaper now to pick up a salvage 8.8 (97 or newer ford exploder) and do a conversion (they are all over for 250.00-350.00) + gears (if you have a i6). I dont know what shafts exactly you are looking at but price is probably about the same. Plus any more you would spend on an 8.8 would compensate for your new rear disk brake set-up.

yea i looked into doing an axle swap...found a good price for a dana 44 but i dont want to go through welding the perches and whatnot. figured itd be easier to just stick with the 35 and do some upgrades to it

You are going to get a lot of opinions on this. I ran 35's with the stock D35 for a couple of years without isssues, but I didn't push it. Having said that, a member of our club broke their D35 with only 33" tires... I think if you upgrade the shafts, you will be OK but it depends how hard you wheel... the tubes are also prone to bending so you may also want to look into an axle truss.

The 30 spline shafts for the d35 are pretty strong. The weakness is the housing, carrier, and gears. But if you take it easy it can be wheeled with 35s.

The tubes are the same tubes used on the TJ 44.

30 spline shafts, a c-clip eliminator kit,a truss,heavy duty cast iron diff cover is what will work the best but the problem will still remain is the weak carrier. Putting all the money that will be needed to beefing up the D35 just isn't worth it. Go find a Ford 9" out of a Crown Victoria, weld on a few brackets and your well on your way to a much better rear end than even a D44 or 8.8 .

My husband did some upgrading to his d35, Shoot him a pm (adamag25) and ask him.

You refered to the housing as weak, last i checked the tubes were part of the housing. So if you were not referring to the tubes I guess your talking about the pumpkin, and last I checked I have never seen anyone that had pumpkin flex issues. Judging by your standards I guess 44 housings are weak to correct?

LMAO, man you are pulling a lot of assumptions from very little typing on my part. The OP asked about upgrading shafts in a D35, so I addressed this. He specifically said he didn't want to go through the trouble of putting in a D44, so I didn't bring that up. Though if you really want to dig into details, he didn't want to have to put brackets on a D44, which means it's not a TJ D44, which means it may have bigger axle tubes than the D35... but that's not the point.

Saying the housing is a weakness doesn't mean it's a weak axle. Even tanks have a "weakness". Upgrading one part, the shafts in a D35, moves the weakess to a different part. You're right that pumpkins (part of the housing) don't flex much, but I've seen more than a few crack. I've also seen grenaded spider gears and carriers in D35s. I haven't personally seen a broken D44 pumpkin, but I'm sure it happens. Lots of axle housings can be considered a weakness. That's what trusses are for. BTW, if you want to have a technical discussion, I'm happy to participate. Ending you post with rolleyes made me think you had something else in mind.

You said they have a weak housing, what kind of assumptions am I making?

You said it had a weak housing, Im waiting for an explanation. Tubes are the same as the so called "stouter TJ 44" (nobody seems to have many issues with it). So what are you referring to if its not the pig or tubes?

OK, you still have not answered my question. Tons of people upgrade to a superior super 35 kit and run 35s on it with no issues or truss, how does that make the weak housing stronger?

You sure are jumping around the bush alot, the housing is the diff and tubes right?

If you upgrade to a Super 35 like i believe you suggested, you have to use a full case locker (detroit, arb, etc) set up for 30 sline shafts which eliminates the weak stock carrier. So you have now upgraded the shafts (weak point), carrier (weak point), no more spiders (weak point), add a CCE kit tokeep the axle from walking if it does break, and you are left with the ring and pinion which usually break do to the shafts either breaking or flexing, and you also have the stock housing itself left.

Hardly believable. Diff cover maybe, pumpkin itself...... Not to many people are going to buy that one. Have you even even changed your own diff fluid? I would venture to say you have never seen the inside of a diff, let alone have a clue about the strength and thickness (hence, your statement above).

Yes they "can crack" but it is so uncommon in 11 years of trails and wheeling I have never seen it, and I have seen about everything.

I am sure you have ever seen a broken/cracked pumpkin at all.

I know. But it is all realitive to what stage your build is in. What tires, motor, tcase, tranny, etc determines axles.

I am still waiting for your response to the weak point of the housing.

The fact that you are avoiding the question makes me think you are doing alot of research right now to find an answer to something you think you read online somewhere.
