you might not be able to tell, but it's a polished up LS1 DS

 

dampner

 

looks like an ordinary driveshaft thats been polished to me..

i have a drive shaft from an LS1 and mine is a lot beefier than that. are you sure its an LS1?

 

Yup, it's 3inch in diameter. And I'm not sure how many ordinary driveshafts came with damners.

Tom

 

More than likely a polished LT1 aluminum driveshaft.

 

What would make you come to that conclusion?

Tom

 

The LS1 shafts fail a lot, so I'd be happier if that were the case anyway.

 

What exactly will that driveshaft do for you that your current one wont?

 

Consume less power and absorb vibration

Tom

 

The ones that do break are behind very strong engines equipped with M6s, and only at high RPM clutch dumps with a strong aftermarket rear and sticky tires. Other than that...

 

Hey I got one of Those !!

 

The LS1 driveshafts are the weakest of all aluminum OEM f-body driveshafts.

Not a bad price. How much was the shipping?

 

 

Shipping was only like 25 bucks if I remember correctly. And why does everyone keep insisting that it's an LT1 driveshaft?

Tom

 

'cause they own third gens, not fourth, and don't know any better.

here's an honest to goodness fourth gen LT1 M6 driveshaft after failure.

here 1

here 2

here 3

here 4

here 5

 

Hope they had a D/S loop.

 

Well not everyone

LT1 years driveshafts were steel, just like the steel 2.5" 3rd gen ones. GM put in the 1LE Al 2.75" shafts to try to solve customers complaints about vibrations. Then most LS1s got the Al 3" shaft. In anycase, I'd think you'd know if it was a steel 'LT1' shaft or an Al one. Post its dia and that'll settled this discussion real quick.

 

wouldnt steel be a heck of alot heavier? He said it was 3inch diameter and how do you polish steel up like that?

 

That's nice, but I stand behind what I said. I can watch any number of sub 12 second LS1 cars running the stock driveshaft at the track or the street with no problems. I've heard of only a few breaking, and all were what I claimed would break them. Oddly enough, 3 of them were nitroused 6 speeds, spraying off the line with DRs...

 

The stock steel one isn't all that heavy to begin with. I was surprised to see that the aluminum one was just a tad lighter.
My 88 Formula came with an alum. driveshaft which suprised me. Owned it for a year and had no idea till a friend noticed it and told me. I replaced the tranny mount last year and didn't notice the alum shaft.

 

I never disputed what you said so you don't need to take it that way. I am just saying that a thirdgen 1LE shaft will hold up better than a 98-02 f-body aluminum shaft.

 

An LS1 driveshaft IS a 1LE driveshaft. Its just updated. In some case's the driveshafts that are in LS1 A4's and LS1 M6's differ. The stronger of the 2 is the Aluminum 1LE driveshaft from an M6 LS1 car. I'm not sure exactly what they are rated with the M6, but if you put one behind and A4, which puts lets stress on the driveshaft in the driveline it should hold up to a significant amount of power. Take a look at the GMMP '02 ZL1 Supercars. A C5 427 block at over 600hp they come with that driveshaft with an M6. Tho at this point one would want to go Chromoly. Especially if your gonna beat on it and launch hard.

 

Go back and read what I said. Thirdgen 1LE. They are both aluminum and interchange with each other, but GM changed suppliers for the f-body driveshafts along the line and they are not identical shafts.


No, they don't. They are the same tubing, u-joints, yokes, length and everything. A 1999 f-body aluminum driveshaft is a 1999 f-body aluminum driveshaft.

Go do some wrenching.

thanks

 

The steel one is 17 lbs and the 1le is 12 lbs. You can polish up steel just like aluminum, just you have to clear coat it right away else it'll rust.

I must have missed where she said it was 3". So its a LS1 shaft.

 

No the differences in the driveshafts I'm talking about are between the ones that are made of steel vs aluminum used in the LS1 cars, I realise I didnt make my point there clear. GM never put a steel driveshaft in an M6 car from 98-02 is what I was getting at. The F-body driveshafts have been the same length, u-joints, yokes since 82. All that has changes is the tubing material, the diameter and the quality. Anyway.... Either way I have experience with both a 3rd gen 1LE and LS1 3'' Aluminum driveshafts and I believe the LS1 driveshafts to be the better choice. I think a lot agree. Just MHO, no need to bite my head off.

All I was really trying to say was that the LS1 Aluminum driveshaft is not as weak as you make it out to be. I'm not trying to argue with you or anything.

 

I'm a GUY thanks.

Tom

 

LT1 aluminum driveshaft (which is the same as a third gen 1LE) does not have the dampener, as pictured above, therefore, this is not an LT1 driveshaft.

 

That's what I thought but I didn't wanna take a firm stand on it since I wasn't 100% sure

Tom

 

Opps. See what happens when you're not paying attention. I offer my humble apologies to you, dear Sir.
