MBRP D Ring Bracket Mount (pair) for '07-'17 Wrangler JK
Why do you need one? If you plan to take your jeep off road and find yourself getting stuck, you will need to have someone pull or winch you out. They'll need a spot to tie on to. If you don't have a D-Ring, you will have to climb under your Jeep, exposing yourself to potential dangers. If you do tie on to a spot, you could damage your Jeep by pulling it out at the wrong angle. A D-Ring Mounted in the right spot prevents damage from happening to your Jeep.
These D-Ring Bracket Mounts are designed to mount to the pivot points on the rear bumper of your Jeep, giving you the angle to get yourself unstuck. Boom.
