Does the 2006 4X4 DC with a 2.5" lift require a diff drop kit? Will it hurt it if I have one on? What are some of the pros and cons?I have heard so many things about this infamous/famous diff drop. Some say you should and some say you shouldn't. Yea or nea?????????????????????????????

Diff drops are useless IMHO. Go measure the difference in the CV's with a diff drop and one without it, it's almost negligible. A diff drop (should be called a rotation) only tilts the front section of the diff down, the rear part of the diff is still in it's original position. So a perceived 1" drop is actually less then 0.5" and when you divide that by the 2 CV joints it is actually less the 0.25" of correction at each CV. Hitting a bump in the road, turning, your steering wheel, etc... creates more change in the CV then that. Some will say "well I'd rather be safe then sorry" but that comment is not entirely accurate either. Reason?, well when you rotate the front of your diff down you add stress to the pinion angle of the front diff just creating another area of possible concern. Not to mention they lower your ground clearance, make mounting skid plates more difficult.

If you spend about 15 minutes over on TTORA in the suspension section, you'll get this message loud and clear. But for anyone that has one installs, and has no issues, there's no reason to remove it.

I'll say nea too.

Didn't get one with my 3" lift. No problems after nearly 20k miles with the lift on.

Have you noticed any more CV angle on the passenger side CV v/s drivers side?

Honestly never checked to be exact. They seem to look the same whenever I glance at the front of the truck.
