Description:

The Firebird had an LS1 Aluminum Drive shaft installed: After changing the rear gears in the car from 3.08 to 3.73, the drive shaft ends up spinning much faster. This causes some vibration with the stock steel shaft. The solution is to install the high performance and better balanced aluminum drive shaft from a LS1 F-body. The LS1 shaft weighs about 10 LBS less than the steel shaft, so the weight savings can help offset some other performance parts added to the car.
I picked up this used 2002 Trans Am drive shaft and brand new GM universal joints for $75.
The end result is amazing. Smoother running, less vibration and even more surprising, is the the reduction in rear gear noise. I attribute the noise reduction to the aluminum not resonating sound as well as steel.
Dyno tests show a 3-5 hp gain by switching to an aluminum drive shaft. The gain is the savings in energy spent on spinning the heavy steel shaft.
The LS1 shaft weighs 11.5 lbs, and the steel shaft weighs 19.8 lbs. But the steel shaft is generally considered to be stronger than the aluminum shaft, as aluminum shafts will fail in drag racing applications with time. For a street car, the aluminum shaft is the way to go.
