More weight to rotate possibly with a larger diameter which takes more force to turn. Guess trade offs against breakage if it is heavier.

A u-joint is physically inferior.

What gives? Are you just trying to make rear end swaps easier?

Obviously the the removal of the rubber coupler and the heavy drivetube increase the strength, but the U-joint adds something that could potantially fail that doesnt have to be there. The prop shaft is always on the exact same plane as the torque tube. No angular motion needs to be accounted for...
Still....looks pretty beefy, thats for sure.

Hey guys,
I am not even going to humor the question of strength between rubber and a Spicer u-joint, that’s just absolutely ridiculous for that to even be brought up.
What I will address is the application of this component. It is not for the road racers that do not shock the drive train, it is for the drag guys running big HP. It is heavier than a stock shaft so yes you will lose 1/1000000 of a hp by using it,
but it can handle sub 1.3- 60' times all day long without fail.
We also tested other types of solid shafts without the u-joint and found them to cause problems, hence the reason why GM felt the need to have a flex coupler. Being that the shaft moves extremely little, those shafts will last a very long time. Anyone with a lifted truck will agree that its driveshaft angle that takes out u-joints.
The Spicer joint we use is the same one powering some of the six second Ultra quick 8 cars that run at E-Town, we felt it will do just fine for our applications.
We are certainly not trying to portray this as the next "must have" mod, it's for the high hp guys that use the power. If you fit in that catogory than we would be happy to help you.

Both these statements show that you have not seen just how thin the stock driveshaft is, and that you have not removed a drivetrain from a C5.

Doug@ECS - I agree, there is no comparison between a cheap OEM rubber coupler and a Spicer u-jount. My question is what's the benefit of using a U-Joint, over say a solid coupler? I know you said you tested some solid units and found problems with them, but isn't using a U-Joint pretty much the same thing (ie nothing there to absorb/dampen vibrations)?

We came up with this set up for the TH400 trans upgrade, we had to shorten the driveshaft and with the trans brake we felt it had to be beefed up. We tried making a solid shaft without the u-joints at first, but it actually caused cracking of the tube itself. We then put the u-joint in place as per a recomendation of an engineer we have worked with in the past and since then they have been 100% trouble free with alot of track testing.
The driveshafts have since been made for stock torque tubes by request, we never pushed this mod since most do not need it. The people who have gone with have all been trouble free since, like JR CRUIZIN C5 who broke a hand full of different couplers and shafts prior to this.
