The Baja JP is flat on the bottom as opposed to vertical tabs, this allows it to bolt on Corbeau brackets or a flat mounting surface without having to order a Baja Adapter. In addition, the Baja JP is a direct bolt-in to most Jeep CJ5s, and all CJ7s and YJs. Like all Corbeau suspension seats, the Baja JP is equipped with the state of the art Corbeau suspension system. The suspension system helps absorb the impact your back would otherwise endure.
