My driveshaft just went out. And I need to get a new one. I got a 92 GTA w/350 auto, and stock rearend. What kind of driveshaft would you guys suggest for me to get. I wand to get a better one then the alumin shaft.
Thanx,

you could try and bigger diameter ls1 aluminum driveshaft.
ebay has a few of them for sale right now.

 

you can order a carbon fiber driveshaft....if you got $800 bucks to blow.

A friend used a stock aluminum third gen shaft in a 10.70s uncorrected 3500lb pro-shifted hemi4spd 477 rat powered car w/ a Dana 60 and it never failed.

On the flip side, some of the 4th gen f-body guys are breaking the stock aluminum shafts, sometimes in the middle; looks like tubing failure, which leads to...

I can't remember the forum, just that it was GM based, but I once read a pretty good discussion on driveshafts. Someone had found that an economically priced aluminum Ford Motorsport shaft worked in their car lengthwise w/ the trans. they wanted to go with. However, it was also thinner wall thickness tubing than aftermarket aluminum shafts.

So, I'd go with a quality aftermarket aluminum shaft and forget about it. That's what I did and w/ 3.73s it's quite smooth at speed. The more gear you're running, the more critical the shaft straightness & balance are. Cars with 2.73s can get by with a sloppy driveshaft far more than a car with 3.73s. That's part of the reason a car with some rear gear will get a thicker shaft from the factory; less flex with the higher driveshaft rpm that come with the numerically higher gearset.

If you're going to beat the ever loving dogcrap out of the driveline, like running 11s with a stick, I'd consider aftermarket steel.

 

I went with the Inland Empire aluminum piece. $360 from Summit (part # IED-CF8200).

Is there really a noticable difference in driveshafts?

 

I am using a Heavy Duty steel driveshaft from Denny's Driveshafts. It is a bit heavier than aluminum, but I was surprised that it weighs a little as it does. Like the guy said earlier, go with a quality aftermarket piece and forget about it...

BTW, we put my stock aluminum shaft into another car that had a stock steel on just to see if we could tell a difference. Yes, it was subtle, but there. The car just seemed to rev a bit faster. My friend swears his gas mileage increased, but I have my doubts about that...

I wanted carbon fiber but my money tree hadn't started to bloom yet...

 

I chose the 1LE shaft. Even tho its .25" dia smaller then the LS1 shafts, it has thicker walls then the LS1 shaft. Lingenfelter has a 3.5" shaft that sometimes can be had on 4th gen GPs for a good price.

 

Stock GM aluminum drive shaft dia's.
1LE = 2 3/4" dia
LT1 = 3" dia
LS1 = 2 3/4" dia

 

The Al LS1 shaft is 3"

 

You better check again, the LS1 Aluminum dr shaft is the same dia as the 1LE and its 2 3/4" Dia. I was proved wrong about it myself.

 

I purchased a LS1 drive shaft from gmpartsdirect.com and was 3 inches.
