Scratched Alumium Driveshaft of a LS1

[black98V6]

sounds like the one I was looking at on ebay.. hope it works out.. thing looked a little bent in the pic..

its 98 and on that they started using the 1-piece as factory equip. 97 and previous you got stuck w/ a 2-piece unless you got the y-87 or just got lucky.

As best as I can tell why they did it. Mind you this is only my personal idea. Was initially to control wheel hop on the manual transmission cars.

They have an ultra low first gear ratio of 3.75:1, that combined with a 3.23 open rear and 225 ft-lbs means you can light up that peg-legger at will.

Without posi, wheel hop is amplified due to one tire being compressed and released as it handles torque. Combined with the already twisting pre-load of the axle wheel hop is insane.

To help combat this, it's my belief that GM used a two piece driveshaft, with a hefty weight to it to help cancel some of that extra torque the manual's get over the automatics.

My wheel hop was like everyone elses - bad! When I swapped to a 1-piece driveshaft, I quickly noticed that there was a slight performance increase that translated to even more wheel hop. Making mine go from bad to horrible. I flat couldn't launch it with any degree of power coming out of first or it'd turn into wheel hop.

Then I installed the posi rear end (along with 3.42's) and it killed about 50% of my wheel hop. To now it only starts getting ancy if the road isn't perfectly plane.

So when I do decide to get lower control arms, that should completely rid my car of wheel hop.

But I think that was GM's quick answer to giving the Manual V6 a bit much power without a limited slip differential as standard equipment.<hr></blockquote>

uhh...hey man quit talkin out your *** .

my 1994 3.4L (Manual yes) came with a two-piece steel driveshaft. but yet i only have 200 lb-ft of tq. ooo...earth shattering, i guess they gave me a two-piece to control wheel hop? (laughs).

thats the stupidist piece of crap ive ever heard. everyone -- this guy is the biggest bull**** artist ive seen.

anyway. a 2-piece driveshaft has a dampner in the middle. as in something to absorb shocks...

thats why the v6 got a two-piece..to make it more cushy. do a little research, and dont wave that "im a mechanic" or "im SAE Certified" bullcrap around here (whichever is your choice..)..

im tired of hearing it.

Well I got the driveshaft today. Its in totally fine shape and is not bent. My SPEC Stage 2 and my driveshaft be on in a few hours [img]smile.gif[/img] .

Bliggida: i believe from 98 up the autos had a one piece steel... and before that all cars had a two piece. manuals from 98 have a two piece i believe

99+ all have steel one piece.

THe new clutch = [img]graemlins/omg.gif[/img] . Its so easy to drive on even without it being broke in yet. First gear is a little tougher, but i would have acutlly have to try not to shift perfectly on it though. Can't wait to its broke in so i can try it out with my new alumium drivesahft [img]smile.gif[/img] .

Some of this stuff is kinda funny. The reason they used a 2 piece driveshaft was to reduce vibration. The one piece has a tendency to vibrate a lot over 80 mph. So, in an effort to make the V6's more tame, they put the 2 piece on them.
