gear vender od ?

It replaces the tail shaft of your trans basically. Think in an Abody the floor needs a dimple for clearance. Nothing big though.

I have friends that use them and they do work well. Just doesn't have a great OD ratio like some of the other options out there. It will make a 3.55 great into about a 2.76 so if that's good for you then go for it. I would call them instead of emailing them.
