Installation of the 4xGuard WJ rockers is pretty simple. Our WJ has larger-than-stock wheelwells that required us to cut off the ends of the 4xGuard rockers and re-cap them. If your WJ is closer to stock and has unmodified wheelwells, the stock 4xGuard rockers will take just a couple of hours to install. Also, the 4xGuard rockers come coated in a nice grippy black powdercoating that is pretty non-slip. Because we had to cut and weld on ours, we coated them with Rustoleum Hammered Dark Bronze.
