Will a ls1 driveshaft work on a lt1?

 

yes.

 

all camaro/firebird driveshafts from 83-01 are interchangeable.

even v6-v8, L98-lt1-ls1....

makes it easier to find aluminum ones to get rid of the vibration

 

i had the vibrashaft issue here : www.ws6.com/shaft.htm

bought a Ls1 3" aluminum drive shaft, and its great! 90% of the viberation at 90 MPH+ is gone..

 

I have an aluminum drive shaft from a 99 LS1 and the u-joint is the wrong size at the pinion yoke... Anyone have any ideas? Can I just get the yoke from a 99?

 

Something sounds strange there... Did the '99 have an aftermarket rear axle? All the U-joints are the same for stock equipment, should be a drop-in replacement.

I know the 12-bolts use a special rear u-joint.

 

I was told that the ls1 driveshafts were different depending on the gear ratio that its car had. Like the 3.23 driveshaft was differnet than the 3.73, etc. I didn't know what the difference was, and a guy at the parts store told me that they were weighted differently in different parts of the driveshaft. Does anybody know if the ls1 driveshafts were all the same or not?

 

The LS1 A4 2.73 cars came with a steel, all others got the alum - still interchangeable.

 

Whoever told you that was full of BS. All Aluminum Dr shafts (1Le, LT1/1LE & LS1) are the same and will fit all V8 3rd & 4th gen cars. Both Mamual and Auto.

 

Sweet! Thanks a lot.

 

They're not all exactly the same, on my auto driveshaft the slip yoke was shorter than the one on the manual one I got free with the trans, but the overall length is the same. & some V6s had a two-piece that won't work without the center support. Anyway, it should still fit. I can't see why the u-joint wouldn't work, never heard of that one before. Sounds like it's time to research what kind of rear that car had in it.
