Just like it says. My car is stock with 130k miles. Should I pick up an alum DS? I know on the V6's it helped a lot since they were 2-pieces. It's only $50 bucks. Duno if its an ls1 or lt1 1le but either should fit, correct?

 

It will fit, but don't expect much difference, unless you currently are experiencing driveshaft vibration problems at high RPM. HP difference is minimal:

HMM. I just bookmarked that page, thanks. I was expecting a little more than that I guess. My car vibrates a lot, but hell it's a vert on crappy roads. Not an easy thing to figure out.

 

For fifty bucks, that is a pretty good deal. If you don't use it, turn around and sell it for 100-125 bucks.
