I just got done replacing the 2-piece DS for a LT1 1-piece. There is not that noticeable of a diffference until the car is in the upper RPM range though. Weight difference is very obvious. Only thing I'm questioning is there is a little more gear noise in back. Any comments on that?

 

Yup...you will be getting more noise than with the two piece.

When I first put on the one piece...I said "WTF?"

You don't feel it until you get into the higher RPMs as you said...I think it is worth it though. If you can pick the part up cheap, have a few hours to kill...might as well.

 

how much?

and where?

 

how much :free-10$

where: your LT1 friends

yup more noise.. kinda like a lil gear whine i guess, its no biggie, turn the raido on

 

Well, I'm glad that I got that 2-piece junk out of there. 1st gear there really is no difference but in 2nd, and so on there is in the top RPM's. The hardest part about this was jacking the car, otherwise it took me only about a 1/2 hour. Well worth it for $30.

If you have a V6, get a hold of your V8 friends, because all V6's should have a one piece!!!

 

what exactly is the advantage of a one piece...?
just less slop so more responsive?

 

Plain and simple the one piece wieghs less. About 1/2 as heavy as a 2 piece. The lighter DS allows the ENGINE to accelerate faster and easier. Does not make power, but frees up power that is already there. Works the same way as underdrive pullies do. So not even will car be quicker, but better gas mileage as well. Same thing would happen if you put lighter wheel on your car.

One piece

 

Newby here...

What are you talking about?

 

replacing the v6 2 peice steel driveshaft with a one peice steel drive shaft from an LT1

 

see thats the prob not allot of f-bod enthusiest here so where else could i go for cheap? a yard maybe??

 

Sure anywhere that has used f-body parts. I got mine form speed automotive for $25, shipping was free since it came with my rearend.

Anyways I fecked up my 2 piece jsut runing it hard, its a simple and worthwhile mod. Taking the stock 2 piece is a bit of a pain though.

 

mine came out rather smoothly after i realized that there was a bolt on top of the carrier bearing

 

I was just wondering if there was a difference in the lt1 manual and auto driveshafts...and if there were any differences in the rear end???....any comments will help thank you

 

all 4th gen d/s will work

the rearend from a Z (auto will have a 2.73 gear, and a 6 speed will have a 3.42) will work in a V6.. cars equipped with TCS (traction controll system?) will fit but due to the differences in the ABS system the rear ABS will not work properly, unless you replace the reloctur wheel

 

which brings me to my next question...what gears does my stock 3.4 have....i believe they are 3.23's if i'm right...it's an automatic...and thank you for the information..helps me out alot
