Yep. Before anyone tells you its bad, bad, bad--I've had mine on for 2-3 years and it works just great. Do a search, as I've said my peace about it several times now.

Sure I've done it and like Brad said, I've had no problems.
Additonally mine is stock height with nice, normal springs that haven't been butchered :p. It connects a standard 12-bolt rear to a 700-R4 transmission.

It will fit, it requires you to remove the carrier bearing and housing leaving an oval hole. If there hasn't been any damage done to the truck, the driveshaft will fit right through and leave you an inch or so on each side (or at least mine did, but mine is a pretty big driveshaft because I'm running a fair amount of power through it).

A few notes of caution:
1) Get it built by someone that knows what they're doing. Find a good speed shop and get their guy to do it. Tell him what it's for and all that. It'll save you a lot on down the road. As a general idea the driveshaft should be somewhere around 4 inches in diameter. More if aluminum or going behind a strong engine.

2) If you are planning to run a lot of power through it make sure to tell them that too, and then get ready to widen the oval where the carrier bearing sat. Otherwise it'll rub.

3) If when installing the driveshaft you find that it is more than 1/2" or so out of alignment, it would behoove you to find a way to get that aligned. As long as the truck hasn't been damaged too bad or hasn't had the rearend dropped and not realigned correctly this shouldn't be a problem, but it's a good idea to check.

4) Check the u-joints a little more often than you normally would. Especially if you start feeling any vibration at all. You could save some pretty important stuff.

As long as the above are satisfied, the idea of a one piece driveshaft not working on a LWB is pure bunk. If not all are satisfied, well you're sorta at risk.:p

What are the advantages to the one piece? I have the 2 piece on mine with no problems. I am thinking of going 700R4. Will it hold up to more power?
Thanks

If you change the ride height of the rear end, the carrier bearing has to move. If you don't move it, it gets extra stress from the new driveshaft position, and will wear out more frequently.

My '67 GMC long bed came from the factory with 1-piece. I'm still using it, howver it's been shortened to accomodate the 700R4 and short wheel base

Can you remove the carrier bearing, and the... well I don't exactly know what its called.(the thing that the carrier bearing resides in)
Because what I'm understanding, if you drop your truck, or some other things it wont work right. Can you just remove the whole thing and then just build a crossmember?

would take alot to build a new crossmember...

the trailings arms are mounted to it.....

Crank · 09-26-2002, 03:54 PM

Well could you do it if you were not planning to keep the trailing arms? Like say if I was to like jack up a truck or use a triangulated 4 link?
