is this a direct bolt in...is it any better than the stock 3rd gen shaft?

 

It's a straight bolt in and its lighter than the steel shaft.

 

any stronger?

 

The LS-1 makes more horseys, so I'm gonna go out on a limb and say yes.
I did this swap as well. It's one of the few where you actually notice a difference.

 

ic ic...couldn't hurt tho...whats a good price to pay for one?

 

Max price for a used one in good condition with both end yokes, $150.

 

alright...thanks..

 

I paid $125.00 for mine so that sounds about right.

 

I went to a parts lot to look for one, and they told me there were two different sizes. Which one fits?

 

Go back and tell them thier morons.

 

im with pasky.....but yeah i got a LS1 alum. driveshaft on mine and it was easy to put on .....as for performance i do hear my transmission thump 3-4 times more than with the original driveshaft-broken rubber trans mount i guess it spins it easier or something

 

Mine had a 4.11 in it with a t5, maybe it was more noticeable.

 

They are right. There are 2 different LS1 shafts. You moron

There are 2 types of LS1 shafts, steel and aluminum. They both directly bolt on.

 

They actually told me there were two lenghts available. Is there a difference between an auto and manual car?

Marc, the electron blue must look great on the car

 

I have a feeling they might be confused. There are 2 different types:

The 2.5" steel shaft. Found on 2.73 geared autos.

The aluminum 3" shaft. Found on 3.23 geared autos and all 6 speeds.

And although there might be a difference in length, it is very minimal, and the 2 are still interchangeable.

I am running an original 6 speed LS1 shaft in my 700r4 equipped car. And other than a lighter wallet, a slightly lightened driveline, and the inability to remove my driveshaft with the rear drooping (4" Mufflex), I saw no performance gain whatsoever.

And the paint looks great, even after 3 years! Thanks!

EDIT: The aluminum LS1 shafts incorporate a damper in the shaft, helping to eliminate driveline vibration and harshness. It cured the vibration I had at high speeds, which seems to be a common problem. I believe this same shaft is recommended for this same concern in a GM TSB.

 

Thanks for the info. So you didn't see a gain? I thought less rotational mass would give a little better acceleration. Oh well. I think I'll still do it though, I want to lighten the car where I can, to help offset the weight it's gained from SFC's, larger sway bars, etc. The dampener should be nice too.

 

When I can finally drive mine again, I'm getting one just for the dampner on there. I had a vibration with my old setup, but with a new motor and soon a trans, maybe it already went away?

 

No, he was referring to the aluminum. Im quite aware of the steel shaft that was put in automatic v8's with gearing lower than 3.23. Either way, their both the same lengths. Once again, their morons if they think the steel is longer than the aluminum.
