front drive shaft

The 7" DC lift will be done this weekend. I need a longer front drive shaft. I live where it snows all winter and i have to drive the Truck on snow days to get around. Iv read that most shafts are for slow speeds or you can burn them up, I will see speeds of 35-40mph.

at stock lift, you can do 55-60 with no probs.

Ive ran my Tom woods shaft at 70 MPH in 4wd before without issue
I just remember reading that you can burn up the CV with higher speeds on a bad boy jr.

Don't mean to be an a$$. But is this your first 4wd? The reason I'm asking is your own question concerning reading VS driving. Anybody that use's 4wd at those speeds is UMMMM?

I don't understand. ummmm what. Thats pretty average for around here when driving in the snow. I really couldn't imagine going any slower on a snow covered road. Experience is the key when driving on snow not exactly speed. I know a guy that could out perform any of us in our 4x4's in the snow and he drove a 76 camaro year around. Well atleast when he the snow wasn't up to his rockers.
I think he is talking about buying like a bad boy jr or something like that and it saying their not made for high way speed
I don't think it is the speed that will kill the shaft (or u-joints), more the angles. You should get a t-case indexing ring, and get a better angle on the shaft, and you'll be set. I've run my stocker in 4Hi at 70mph+ for long periods of time without issue. That is w/ about 6" of lift too.

:withstupid:
The only problem you may have, is if you flex too much and bind the u-joint.
I wouldnt worry about it at HW speeds.
The CV on a bad boy JR is not meant to see very high RPMs. It is what's used on tractors... like the shaft between a tractor and a bush hog. It's engineered to get high angles so they can cut sharp corners but they don't see very high RPMs. If you run it at highway speeds it will burn up, but I don't know what is considered "highway speeds."

No this is not my fist 4x4. Iv lived in the high country my whole life and have owned nothing but 4x4s for about 15 years now :flipoff:. 35-40mph in the snow and ill get passed sometimes. So a BAd boy Jr is out. So maybe re-index the t-case(looks like alot of work). Ill call high angle in the morn and see what they can do. Is there a vendor on P.S. that can help me out?
re indexing is a cinch :bigthumb: Just pull the t-case and install the seal adapter and indexing ring and walla....your done :D:
Well I forgot you have to hack your factory crossmember a little to make it work. :hack:

I was looking for some feed back, you know differnt ideas. i know what my options are, but i would like to know what problems and what not others have had. You have not offered up anthing to help. But like you said you dont mean to be an A$$ so if you cant help oh well.
