JK and JKU are fairly simple to install. Pull the pins holding your grill in place, pull the grill forward two inches, drop insert in, making sure it's not resting on the sensor on the bottom right, replace grill and pins! The fit will be very snug, ensuring your insert will not shift or fall during road time. Easiest mod you'll do to your Jeep! We include instructions with every insert, but if for some reason yours are missing, email us, and we'll send you a copy!
