What performance does an Aluminum Driveshaft give?

[jim_howard_pdx]

More rear wheel horsepower.

Smoother because aluminum absorbs vibration.

Not as strong as a steel drive shaft. You do not find aluminum drive shafts in anything running 9's and under.

Graphite shafts even better for horsepower and anti vibration, but twice the cost. This is what the exotics are moving toward when and if they need a driveshaft.

Hope this helps.

I too would save your money. Replace your U-Joints and most vibration issues will go away. Ford balances every factory drive shaft.

Put the money toward stuff that builds power and faster ET's . Street Slicks, steeper gear ratios, NOS, these are things that really make the car bark....
