The Baja XP off-road suspension seat is equipped with the Corbeau suspension system, to provide superior cushioning and significant energy return upon impact. Its extra high side bolsters will absolutely eliminate body shifting. The Baja XP has four vertical tabs on the bottom of the seat to allow it to bolt to a roll cage. If you plan on bolting to a Corbeau bracket or a flat mounting surface, you'll need to order a Baja Adapter (A22002F), which bolts to the bottom of the seat making it a flat mounting surface and eliminating the vertical tabs.
