I have a vibration in my car above 55-60 and I'm pretty sure it's caused by a bent driveshaft. I've heard of people using LS1 driveshafts in 3rd gens. I was wondering if this is a direct swap or if it requires cutting/fabrication, ect. I guess I'm going to have to replace my driveshaft and I want to make sure the LS1 piece will work before I buy it. Thanks!!

 

Anybody?

 

direct replacement

 

Ah, yes, finally an answer! Thanks!! I can go lay down some more cash now

 

Are the the LS1s much better? I thought I read somewhere that they were bigger than the 3rd gen L98s. What's a good price for an LS1 driveshaft?

 

From what I hear its thicker yet hollow or something. Its lighter and also better balanced.

My question is...is ALL LS1 driveshafts like this? or is it only certian models? Cause imma go searching probably on thursday and I dont wanna end up buying a driveshaft tahts exactly the same as the on I have now O_o

 

3.23 and 3.42 geared LS1 cars came with aluminum DS from the factory...

2.73 equiped LS1 cars have a steel DS from the factory

 

they all seem to go for around 100$. also, a quick easy(from factory) a car with Z-rated tires will have the alum DS, easiest way IMO if you are unsure, take a magnet with you.

 

revlimit,

not that it really affects the conversation, but our driveshafts are hollow as well.

 

Does anyone know the weight difference between our steel ones and the aluminum LS1s?

 

a lot probably 50-100 lbs.

 

wtf? 50-100 IBS? they dont even weigh that much...my stock one might of weighed like 40 if that. The ls1 ds I have is maybe 15-20 or so.

 

the ls1 ds is that from a manual trany or a auto tranny. or does it matter.

 

It doesnt matter both bolt right up

 

What about the u-joints or the yokes? Do I need the ones from the LS1 or what?

 

The driveshaft I bought had all the u joints and yoke already on it...so everything bolts right on..im not sure if you can use your old yoke and u joints or not. Id say if your buying a used shft id replace the u joints with good ones. There is where I bought my driveshaft from. It was about $240 or so with shipping, but everything is bran new. http://www.eecis.udel.edu/~davis/z28...up/misc/ls1ds/

 

dont get the LS1 shaft if you plan on using drag slicks, it will rip it all up. its about as thick as a 3 inch piece of exaust pipe. the steel one is a bit thicker. the alum is better balanced though.
