since the gears and lockers already sitting in the garage

so next step will be a heavey duty bumper and winch for sure,and i will put 37'' tires on after the 35'' done.DUE to the weak battery of jk,you may wanna change a better one,or stay with 8000lb winch,i think 8000lb is good enough for a 4000lb weight jeep,just dont try to winch a hummer outta mud you will be fine.
