V6 Driveshaft

[Riggs]

I have a few questions on driveshafts for my V6. First question is - is it too horsepower that causes it to fail or is it top speed? Secondly is it really worth it and are they benefitial on a V6?

Fail ? I haven't heard of them failing. They're heavy, and noisy, but there are people who have been over 130 mph w/the stock driveshaft. It's the same driveshaft as in the GT.

I was under the impression that over a certain speed they can break apart?

sorry not true... very different driveshafts.... I know of 3 guys that have had their driveshafts fly apart on the dyno... all seemed to report that it happened around 130MPH...

One more question - Is the V6 driveshaft the same as the V8? Because many websites sell two seperate driveshafts a V6 one and a V8 one.

They are different... also the manual and automatics are different lengths...

good info, thanks. I had no idea the driveshafts were different.

so from now on I'll keep it at 129

Actually the drive shaft in the V6 is rated at 115. It starts to vibrate at that speed. Personally, if you plan on going that fast I would replace it.

I just put in a new driveshaft yesterday!!! WOW... very noticeable difference... cars a bit peppier and a lot smoother a highway speeds!

doubt I can get there with the 118 mph speed limiter.
