I'm looking to add a 2wd low setup to my 2002 HO 6speed. From what I found so far there are 3 kits available, BD, Pacbrake, and Posi-Lok. Is there a preference of one over the others? is there anything else I missed? Two are vacuum based and the other is a mechanical setup.

 

I want it for trailer maneuvering, taking some stress off the clutch.

  • The option "shift on the fly" is advertised with or without CAD (center axle disconnect).  You will need to look at the axle to see if there is a CAD unit attached.  If you do not have the CAD - end o

Except the free spin hub conversion will run someone approximately $2000...  You could replace a lot of axle u-joints for that kinda cash.

 

On top of that ZERO gains to MPG. Free spin hub doesn't do much for reducing drag. The only bonus they will provide is standard cone and race bearing from years past instead of unit bearings of today. The only time I suggest the this is for guys with huge tire and lift kits because the bearings will hold up better in the long haul.

Agreed that it doesn't really do much for MPG improvement....but making a tight turning radius is a bit easier....but I didn't do it for that either.  I figured that if I spent more the first time - I could save in the long run.
