The Baja Ultra off-road suspension seat will enhance not only the look of your vehicle but also the overall driving experience. The Baja Ultra 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.
