Installation Time: Afternoon
April 09, 2017
I installed this while replacing my over axle pipes, so access was easy. I have been adding parts to the car that I think, ideally, it should have come with. The stock driveshaft is not the most elegant or light design.
My review is after first impressions - there's definitely a seat-in-the-pants difference, I didn't notice more noise (I also have a billet shifter bracket, and that added a slight amount) and have not noticed any vibration (haven't gone above 100 mph yet).
Carefully inspect the part when you get it: damage in shipping will likely result in vibration because the balance is gone.
Tip: you might want someone who can apply the parking brake while you're torqueing down the bolts. It took me a long time because I kept having to crawl out from under the car and go back to reset the parking brake, rotate the shaft, rinse, repeat (and I added the install time of the over axle pipes). With two people, you might be able to do this in 1-2 hrs.
