SD Front drive shaft installed.

[OBS-Addiction97]

My truck originally had the TTB D50 with a single joint drive shaft. I finally got tired of not being able to go over 20 mph in 4 high with out it vibrating like crazy.

I considered finding a obs F350 drive shaft but they are pretty rare and utilize the smaller 1330 U-joint. SD drive shafts utilize the larger 1350 U-joints. I picked up a Sd drive shaft for $100 off Craig's list.

Some one suggested I call Jesse at http://highangledriveline.com/f-350.html. He makes a conversion flange that bolts up to the 4407 BW T case. I also got a forged 1350 pinion yoke for my D60 from him.

The only thing I had to do was get the SD drive shaft shortened 1" and re balanced.

Thats awesome, nice work thank you for posting this! About how much was the flange for the transfer case if you dont mind me asking?

 

[OBS-Addiction97]

I paid about 300 for both the flang and yoke. I believe the flange was $140 ish. I didn't have to get the pinion yoke forged either. I just like over doing stuff some times.

*** Also a side note for anyone considering this *** when looking for a super duty drive shaft make sure the CV joint Is spicer. Apparently the 99-00 trucks didn't have a spicer CV and it won't work with this flange. The later SD have the spicer CV joint.

Nice, how was the quality of yhe flange on the 4407?

 

[OBS-Addiction97]

It was a very nice piece. No issues at all.

Good. I was planning on ordering one and onstalling it before winter

I did the same thing with the conversion flange and 1350 forged yoke but the register hits the front output shaft nut. I know 03 and up have the hole in the middle to clear it. Might take a 1 1/2 holesaw to the middle to get it to fit on the cv flange. I spit my stock driveline out after hammering it through a rock pit in 4low and 37s lol

Ya that's what happened to me. I bought the early drive shaft and realized immediately it wasn't gonna fit. A quick look on Craig's list and I found the later model drive shaft.

I also proly broke my stock 250 shaft 3-4 times off roading or pulling some one out. I never did a 4hi boost launch with it. I was too scared of taking out my bts with it.

I think I can get a newer flange off the inter webs with the hole in it to fit. Yeah I was surprised how easily it broke. Curious to see how it holds up for you.

I guess I got lucky with mine. Both the 95 and SD shaft were 1350 joints so it was a direct bolt up to the axle. The flange wasn't a issue because the shaft came with the NP271 transfercase.
