The all new reinforced cage kits come with everything you’ll need to strengthen your factory roll bar into a solid foundation if a roll over takes place. We start off with 1020 .120 Wall DOM tubing which is one of the strongest materials available. Each kit includes the new Knuckle System that attaches to the factory roll bar, using a unique pivot and fastening point on one end and grade 10 fasteners on the other. Making it one of the strongest and the most solid mounts available for your Jeep®. All of our cages were engineered to bolt-in and require no modifications to the vehicle to ensure a rock solid install while creating the strongest cage kit available.
