This unit is used, but is in perfect working order. It is already installed in a diff carrier, and it will be included. Ready for your ring gear.
I cut consitent low 1.70 60 ft times with this unit (and one 1.68 60 ft) I NEVER did a burnout with it. No need to. It has VERY few miles on it,but I would still recommend new bearings for safety's sake.
