We are in the development page of this drive shaft. So far there are a couple prototypes in use with a good success rate at fixing the vibration problems that many of these trucks have whether lifted or stock. The shaft is a single piece replacement for the stock 2-peice drive shaft. It will eliminate the stock carrier bearing. There are a couple more wrinkles to iron out before this is available so please click the green button on this page to be notified when they do become available.
