Now that I have found a ride for my I will be upgrading it this weekend. OME 2.5 " lift Slee Sliders ARB Front Bumper Yotatech says do the diff drop kit with the lift. A few, Slee and another trusted mechanic says it doesn't need it. A couple of runner guys I know (Bill Morgan, Scott Yoder) recommended doing it. I decided to have it done with the lift. We will post pictures on Monday when it is done.
