The carrier is the part inside the pumpkin that houses the side gears and spider gears. Basically its the differential itself. Mine is a Trac-loc OEM posi unit. Not a true locker, but a definite improvement over an open diff. I have the gears for the rear axle only as the front carrier and gears were slightly damaged as they were grenaded on axle hill. If you chose to upgrade to a locker at a later time, this would give you a good R/P to transfer over. If your interested. email me.
