Jason Pruett's JK Unlimited has a 4-inch Rancho suspension, Detroit Locker in the rear, Aussie Locker in the front, and 35-inch Toyo Open Country M/T tires. Notice the front fender flares? This is a popular mod with the JK crowd. They're simply modified factory units. Some JK owners even use cheap plastic clips to attach the flares to create a fusible link in case the flare should meet an immovable object on the trail.
