I wanted to wheel the Jeep and it hold up to some hard rock crawling trails, so I contacted Rock Your 4x4 in Knoxville, TN for the hookup in installing a Dynatrac Pro Rock 44 w/ Eaton E-Locker in the front. along with a PSC Big Bore XD Steering kit, Yeti Steer Smarts, Reed Racing High Steer Knuckles, RCV axles, M.O.R.E. Engine/Transmission Skid Plate, Switch Pro System, Rock Hard 4x4 Sport Cage, and Metal Cloak Dual Rate 3.5 Springs Front/Rear. Love the Jeep and how it has performed.
