dana 44s front and rear with cromo shafts

your dana 30 wont hold up your dana 35 will not hold up. if you have a rear dana 44 i would put the super 44 kit in. boggers are extremely hard on axles.

that should be ok, but if your hard on the throttle at all, you'll bust that 35 even with an axle kit... D44's should be on the TO-DO list if your thinking of 37's though.

Lock a 30 or 35 with 37's and you are pretty much guaranteed to break em - super or not.

There is not an upgrade that will make a 30/35 combo reliable on 37's. Lockers make it even worse.

A locked 44 with chromoly shafts can BARELY handle 37's.

Just for reference, I would like to see video of how you wheel to verify your statement. Are you kidding? 44s and chromos will last on 37s if you are legit and smart about your wheelin. I am very fond of telling people go nice or go twice but I think, depending on which 37s you go with, that a 44 is more than enough axle to stand up to 37s.

Im going with boggers, i dont do real hard wheeling, just mud but i do want to get locked up soon. So i can get just beef up my axles first then get the tires with proper gearing then the lockers correct?

I think you are misconstruing my statement. I don't disagree that alloyed 44's are "enough" for 37's if you wheel smart. Otherwise I wouldn't run them. My 37's and alloys are recent additions. I'm 30 spline in the front and I am light on the skinny pedal so I don't forsee any problems in the terrain I run.

Does that make a Cr 44 "more than enough"? For everyone? Not in my opinion as I know of failures (second hand) that were not in the most extreme of circumstances. It is nice however, that some manufacturers' alloy shafts have great warrantys.

Also take into consideration that not all Cr axles, u-joints or carriers are created equally and sometimes "accidents happen" even to experienced wheelers.

There is nothing on earth that can save a locked D35 with any 37" tire on it. You'd probably break it just turning a corner too fast.

What if i dont get a super kit no lockers no beefing up axle, just the 37"s on my d30 and d35?

To answer this question....

I'm going to revise what Jack said.

There is nothing that can save a DANA 35 from the wrath of a 37" tire.

A D35 is not an option.

if you want a head ache

YOU WILL BUST YOUR AXELS IF YOU DO NOT CHANGE OVER TO DANNA 44'S, But if you want to be broken in the woods go ahead I wont pull you out for stupidity:eek:

Then i need to get some 44's where do i start looking? how much will a set cost? What are all the components i need to change over in an axle swap?
Your Dana 30 can survive 37" tires. However you'd be better off if you at least put some alloy shafts in it and better u-joints. If you really want to keep the D30 and put extra beef to it then a Super 30 kit with 30 spline chromoly shafts in it would be the way to go.

So with that said if you are really wanting 37's then you either need to look into a TJ Dana44 swap in (Completely Bolt In) or a Ford 8.8 swap (Fab work required unless you spend a decent amount of $). It's funny Joe and I were just talking about this today and I had mentioned this thread. These days you can find a stock D44 bolt in for around 1200-1500.

And on a side note: Mr. Clifford was dead right in modifying my previous statement. No matter what you do to a D35 37's will shred it.

Please excuse my ignorance....So keep the 30 in the front and get a super 30 kit, (what exactly does this contain? a locker?) and beef it up, How would this be done, extra brackets?, welding? Also get the 30 spline chromoly shafts, i would assume there is a kit for this. Then swap the 35 out for a tj 44. What about a used wagoneer 44? what exaclty is a "bolt in", does the backspacing change for an axle?

A Wagoneer 44 would need fab work as it used leaf springs instead of coils like a TJ... it can be done, but you'd need the TJ mounts for springs and control arms welded on to it.

A "Bolt In" D44 from another TJ is exactly that... unbolt everything and drop kick your D35 to the curb and bolt the D44 into place. They are a perfect fit and don't require any welding.

The back spacing won't change if you get a D44 from a TJ, but if you get one from a Wagoneer, it would because the Wagoneer has "Full Width" axles wich are much wider than those of the TJ.

Yep - the D30 is quite a bit stronger than the D35, plus it helps that its up front and doesn't take all the abuse the rear axles would.

A D30 Super Kit usualy contains a locker of your choice(depending on whom you buy it from), new axle shafts(chomoly), new U-joints installed in axles, wheel bearings and seals. That would be all that is needed to "beef it up".

And the only other thing to consider when going with 37's are new gears for those axles :D
