Yeah it does seem pretty weak, but here's my thinking. I would say they used that same setup on the big block cars. A 409/425hp should have broke it probably as easy as I do, let alone those special few cars who had the 427 in them. I've seen some upgraded bearings and entire driveshaft with a slip yoke in the second piece for some drag racing and stuff, but wasn't really wantin to fork out a bunch of money for it. Can't afford it. Wish I was a little more car wise then I am. Only 20 so lots of learning to go lol.

Couple of things. If you want to upgrade to a beefier unit you can try Inland Empire Driveshafts. http://www.iedls.com/
I haven't checked the prices myself but have heard that the carrier bearings are strong. Supposedly used for hydraulics and airride setups. One question, do you install the carrier bearing with the rear suspension under a load or not?
I belive the proper way to install is to have the rearend supported with jackstands so that the suspension is compressed like it would be when sitting level on the ground. This may be affecting the bearing when it is installed. Also I dont think that it is a good idea to try and upgrade to a 1 piece driveshaft on these x frame cars. With suspension travel you would run the risk of the drive shaft making contact with the frame. That is why people use slip yokes on the rear shaft when the have modified suspension systems like hydraulics.
