I got new gears and lockers installed from here for my Jeep jk without any problems. The gears are running smooth and quiet. I'll see after the 500 mile mark how the gears are doing and maybe double check the backlash and see if anything needs to be adjusted. I was not aware of the break in period/procedure though so going home was an obstacle. Carlos explained everything and will take care of you. I think I heard that these guys also do the regear service at rebel off road in Orange County so if anyone out there is doubting these guys don't, they know what there doing.
