Dana 35 ifs axle strength??

[4x4junkie]

Agreed, a Jeep rear isn't really comparable, for the simple fact it's in the rear (where much of the vehicle's weight ends up going toward during launch/acceleration/climbing a hill). I've seen Jeep rears pop axles even behind the little 4-cyl.

A front D35 is able to tolerate more than a Jeep 35 simply because the exact opposite happens (weight shifts off of it during launch/climbing/etc.). However there still are limits to it (plus the fact it's low-pinion will work against you).

I s'pose you could always try it and see... Maybe you'll get lucky and it all holds together. If not, you can then start looking into other options.

Yeah I might try retrofitting a Dana 35 out of a ttb if I break the sla one.

If you have a complete TTB D35 with gears, the carriers are all the same if I remember right so you can put whatever ratio you want in it... I went from 3.55 to 5.13...

Mine has a 3.27? The large carrier if I remember correctly is 3.50 and up, I have the one for the high ratio gears.

I'm already building the 4r70w out of the explorer, it should be able to hold around 550 at the crank when I'm done with it. Basically it'll be a little stronger than my factory block will handle.

Stock block won't live long at 550 hp. Limit is around 500hp even then depending how hard it's used. Stock block will split right down the center. At power level you want plus using spray better off with Ford Racing block

You have to remember that only a percentage of the power is distributed to the front wheels. And you can't really compare different manufacturers axles, think how much stronger a ford Dana 44 hp is than a chevy Dana 44.

With the power you want to make that percentage is already going to be over the top for a D35 no matter its position in the driveline. If you are after hard launches with oversized tires that hook up the front end is susceptible to the same fate as the rear end in the overall picture.

For about 4 years before I got into Rangers I was very heavy into building 5.0L engines. In that time I helped out on a few Mercury Mountaineer builds and they were all RWD applications for a reason. Not saying the D35 is going to explode and take out half the universe but I wouldnt expect much from it. If you build your transmission correctly for the application youll be more than surprised the kind of power you get to the front wheels. Automatics soak up around 15-20% of power in their stock form. With a built automatic you can knock that down to 7-10%.

Also you can use the D35 TTB case for lower gears. Both my trail rigs were 3.27 and now 4.56. Its all the same.

I know the limitations of the stock block, that's why I said the transmission built for 550 hp would be stronger than the block. I want the transmission rated at that so I can pull a trailer without worrying. Also I can run a stroker kit with a cam that pulls to 6,000 rpms all day long with a 75 shot of nitrous without worry.

Just so everyone is aware... You cannot put high-pinion gears into a low-pinion housing (and vice-versa). You would have to swap the entire housing. And with the amount of work it would take to sling a D35 TTB under a SLA IFS truck I'd just go the one step further to a D44 (SAS) for it's bigger ring gear.
IFS & TTB D35s carriers do not swap either (the IFS one is narrower I recall).

This is why I mentioned looking into a possibility of using a IFS 8.8" if you must keep it IFS.
