just wondering cause right now i have my stock drive shaft out and i thought it was perty light but i was just wondering what you guys though ya think its worth the cash or no?

 

I plan on adding one to my car some day. One thing i will mention is that the aluminum ones are more prone to breaking. I think i have heard of some breaking with only 300rwhp on a good launch.

 

going from a steel to an aluminum DS will help reduce vibrations at high speeds as well as provide a small weight reduction in the turning mass.

 

IT is quite a bit lighter than the steel one..
Get a 1LE not an LS1 shaft if you can[ noone has broken a 1LE that I have heard of..
The LS1 's are a bit weak..
They are very close to the same price new..
If I recall my 1LE cost 232 new about 2 yrs ago..

 

for the significant reduction in vibration, and the 1hp/5# torque that you gain...i would say it's worth it.

 

Depends on your application. An Al shaft is not suitable for a hi-po car launching on sticky tires. But I'd say it's a worthwhile upgrade for a mild setup. The strongest Al shaft I am aware is the HD Al shaft from Denny's. However, at ~$480 it's far from cheap. Denny's also has a "light-duty" 3.5" Al shaft for ~$325 that would be adequate for most street cars. Lingenfelter also markets a 3.5" Al shaft that is nice. Another good source for shafts is Dynotech at http://www.dynotechengineering.com/ who also offer a HD Al shaft as well as lighter ones. I used to exclusively use Denny's but the customer service and turnaround at Dynotech seems better, even though Denny's is local (for me). So, I have switched. Denny's makes a good product though.

Didn't I hear something about a GM TSB for a free AL driveshaft?

 

Sure, if your car is still under warranty.

 

another question what about the carbo fiber ones i hear they are stronger but also friggen expensive and
gm parts direct has an AL driveshaft for about 230 is that the 1LE or somethingelse

 

and if it helps the gm part # is 10085375
it says its for racing so but ya never know

 

no point in dropping the money on a carbon fiber DS. as stated before, if you want something strong you can check out the aluminum and steel lines that Denny's offers. 1LE is prolably the least expensive alternative if you want strength.

 

10085375 is the 1LE DS, that's a good one to get.

i thought that was the one but wasnt sure im thinkin i might pick one up soon

 

The "consumer grade" CF DS's out there sux AFAIK.

I dont know if this will help you any but ford had a huge problem with there aluminum drive shafts on their cobras, a buddy of mine belongs to a mustang forum and talked to a guy who had broken seven!
