D44 with 40" Boggers

Not really a question you'd ever face on any Ranger except a heavily modified one, but could a Dana 44 be built strong enough to hold up to 40" Boggers and a High HP/High Torque engine (we'll say roughly 350 HP, 350 Torque for the situation).

I know you could use 4340 Chromoly shafts and CTM U-joints and all the other fixen's to make it strong, but could you get a big enough spline shaft to hold up that kind of abuse?

Remember, this is coming from someone who is still fairly new the whole modification thing. I know how things work and why something breaks... I just don't have that much experience with parts and non-stock things.

Thanks for any help.

Agreed. A D44 has a smaller ring gear and pinion than an 8.8. It's a good axle, but you'd have to really build it and truss it to be sure with tires that big.

Time to consider a D60!

With an engine that powerful and tires that large, I'd look into rockwells myself.

Granted, if you are just lolly-gagging around town, a d44 would likely handle those tires and that engine relatively well because it wouldn't likely be engaged often. I don't think that's your intended use though. My guess would probably be a mud-bog, and in that case, you'll want a d60 or rockwells or some other much more heavy-duty axle.

Jey has broken his built-to-the-hilt d44 on 38.5s with a 3.0 motor.

Look at any INDIVIDUAL case you want. Look around at the other forums, magazines and so forth and you will find it AIN'T a good idea to even run 35's on a D30. He's been lucky so far or hasn't thrashed it.

It's just a matter of time and force, lol.

jey broke a yoke on his truck with the 42s on it because the angle of the driveshaft caused the two yokes to hit each other then blew up.

I would have to say it depends on the style of driving and vehicle setup.I've ran 38's with stock axles spooled with 5:12's,with a 90hp motor and they lasted as long as I didn't hammer on it with the wheels turn all the way to one side.I say go for
if it doesn't hold up you can alway resale the axle.

Read the mags, browse the net. I'm not going to do your research for you, lol. Believe what you want to believe, but it's too weak to thrash with tires that big. Some soft mud bogging, maybe. Rocks and rough stuff, I don't think so.

Hey, as I've found myself: you can do it right, or you can do it your way. It'll cost you more in time to do it your way, lol.

as long as you gears are setup properly,drive shaft angles are descent,and you have bumpstops to prevent you tires from biting the fender it will live for a while

Yeah, and maybe the stuff was breaking back when he ran the other tires, lol. My spindles broke 4 mounts after the "insult" to them.

You had a drive shaft on FOR A WHILE, lol? Well, that's not so much of a test is it? As I like to tell people at work: one data point does not make a trend, lol.

And I like the Jeep guys comment: it'll live for awhile...

You just can't make any point here that it'll be okay with any authority. Look around.

i say run what you want to run, if it breaks its not like it can't be fixed. heck i've learned a lot just from the stuff ive broke and it wasnt much.

just remember you are doing it your own risk and if it breaks dont be pissed.

Precisely. It annoys me when people live in denial: you can rebel against the experts if you're willing to run the risk -- but you can't say you're some kind of expert on the subject. There's just too much information out there to the contrary.

What's annoying about that is when they tell OTHERS, "It's Okay". That's just plain wrong, sorry y'all.

You CAN (as I often have) decide to risk a "cheap mod" -- but never fool yourself on it. It just makes no sense.

Ha ha! Simple: get one and paint the bezel, lol -- that's what we did who have such things. Mine is modified Taurus keypad from early 90's Taurus's.
