The Aluminum Drive Shaft! Ive seen lots of questions being presented on these, Figured we could try to round everything up.

I think we all know what a driveshaft is, in case anyone is wondering it is the rotating assembly between the Transmission and Rear end. (think rear axles!)

Lets try to get the following questions answered, and please, lets keep on Topic!

1) What is the weight difference on average between aluminum and stock?

2) What types of performance gains would be expected?

3) When should somebody consider upgrading thier driveshaft?

4) Is it true that the lighter weight reduces low end torque and is this Dyno proven? (I have a hard time wrapping my brain around this one, i understand the idea but it just seems flawed, the drive shaft only rotates when the wheels are moving, sitting at a standstill the driveshaft does not move, so when dumping the clutch wouldnt it increase low end torque at the wheels because the lighter mass requires less power torque to rotate? I could understand this loss of torque on a rear located tranny like the C6 vettes where the driveshaft is constantly rotating the same rpm as engine..)

5) What application would this be good for? Street? Strip? Trailer queen?

6) Is there really that much improvement over stock?

7) How is the reliability? are they easier to break?
