Adding a receiver hitch to your Jeep will absolutely increase it's versatility. Not only can you tow a trailer, but you gain access to a wide variety of receiver hitch accessories such as bike racks, cargo racks and recovery hooks. They're easy to install too. A receiver hitch can be installed on any Jeep Wrangler in less than thirty minutes.
Factory style hitches come with a 2" receiver and most are bolt in applications that also accept just about any kind of towing or rack option. These hitches also mirror the factory towing capacity which is 2,000lbs on a 2dr Wrangler, and 3,500lbs on a 4dr.
