Another Half Shaft question.....

[Hyprspec]

Don't think of it as "if you have "X" parts then your are probably going to break your half'shafts and if you don't have "X" parts then you are safe" thats just not the way it is. Do "X" parts make breaking them more likely, yes they do.

Remember, sometimes things just break. Thats just the way it is. Is it possible for a completely stock srt8 vehicle to break the halfshafts, yes it is. Is it possible for a highly moddified srt8 to NOT break the halfshafts, yes it is. However the latter is far far more likely to be false.

hey, it's simply this. TRACTION is what broke those halfshafts.

Pretty soon we're going to see the next weak link.

I just broke a passenger side half-shaft with simple mods listed below...
Then any solution....

Must've been the floor mats, hyth.

I wish that is true.....

I really think these shafts are poorly designed by DCX. They should not break that easy.

Here in Australia I know of plenty 1000hp+ HSV's etc running a similar rear end setup and you don't hear of this happening. I think the rear end in our cars are flawed to be honest.

Thanks, but what is the way out?

I have heard from some reliable sources that this is the main culpret. Something about the way it delivers the power and vibration. A couple of different "German" cars shops told me this.

For sure the converter and more power in general does not help with the weight of our cars too.

I would think with just nittos and not running them too low on tire pressure you would be fine for a while

Well, I showed it. Later the same day that it blew up my CV joint (inner race cratered) I blew up the Quaife in poetic retaliation.

That'll teach it to mess with My Sweet C.

oh, how the mighty have fallen!

So even the much lauded Quaiffe has its limits. Meister, are you running an SRT rear end or a standard 5.7 model??

If you compare the operation of our standard wheelspeed equalizing system with the Big "Q" it's easy to see that there is a significant difference in their operation. Seems logical to infer a difference in their effect on all the downstream parts!

And remember, NO ONE on any board has shown any real world improvement in drag strip ET's from the Big "Q". Huge real world improvements? Yes! Road Course? Yes!

And for those of you wondering, a higher stall torque converter can actually help these issues. It's not the problem. I would also want the option to disable the lockup for a run.

Hyperspec was right on it... it's TRACTION that breaks stuff. Hook up hard and you can break anything. Stick with street tires and you are nearly safe.
But not completely.
