The Baja Ultra is the big brother to the popular Baja SS seat. It is four inches taller and one inch wider. Its high side bolsters and taller back give you ultimate lateral and head support. Picture sitting in your living room in a lazy boy sofa and that's about how you'll feel in the Baja Ultra. It is quite an aggressive seat so if you're over a 36-38 inch waist, we recommend you move up to the wide version. Please note however, the wide version is huge so be sure to double-check the measurements of your vehicle for fitment purposes. The Baja Ultra off-road 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. The Baja Ultra off-road suspension seat is available in all vinyl and vinyl/cloth materials. As a rule of thumb, the Baja Ultra will fit up to a 36-38 inch waist and the Baja Ultra Wide will fit up to a 42 inch waist.
