Lighten your load and free up cargo space by carrying one rear halfshaft for a spare instead of carrying a left front, a right front and a rear! This Front Diff Centering Kit will allow you to center the front diff so that the rear haftshafts will fit in the front as well, reducing your inventory of spare parts needed to be brought with you on the trail. The Kit will also allow you to upgrade to 12" Brake Rotors for greater stopping power without interference with the cross members and realigns the driveshaft to correct angles.
