How much of a difference would an aluminum driveshaft make?

I have a 97 TA and am wondering if an aluminum driveshaft for $125 is worth doing.

if your stock steel one vibrates like a typical one off the LT1s...they are very worth it

but some don't vibrate.

I got my aluminum driveshaft for $80.

Felt a little quicker, but that could just be in my head or due to wallet weigh reduction.

Unless your steel one is vibrating, I wouldnt worry about it.

How much difference is there between the LS1 driveshafts and the 1LE?

I am going out on a limb and saying no difference. Aluminum is aluminum. If Im wrong smack me and call me Shirley.

I think having a balanced drive shaft is more important than the material it's made of.

Re: How much of a difference would an aluminum driveshaft make?

the difference between the 1le and ls1 is the diameter of the shaft itself. i think the LS1 is 3" and the 1le is 3.5"

or something along those lines.

both are basically the same, i don't think one is stronger by any measurable (or advertised) amount. but they are btter balanced than the steel ones

I thought the 1LE would be smaller in diamter size. Is anyone running or know anyone running the carbon-fibre DS's? I'm sure you'd say more gains there.

Re: How much of a difference would an aluminum driveshaft make?

I broke an ACPT carbon fiber DS (3.8" Heavy Duty) with the car tuned to produce just enough power so it could be driven from the engine shop to the body shop. Took more than 3 months to convince ACPT it was defective, so I could get my $700+ back from them.

I've seen several aluminum shafts break, including a 3.5" Lingenfelter shaft. I run Mark Williams 3" chrome moly.... strong, and the chrome moly keeps it close to the weight of the stock steel DS.

The 1LE is stronger than the LS1... I know of several LS1's that were twisted in half.. but have yet to hear [post up if you have] of a 1LE being broken?..
