The Simpson Vortex II Off-Road Suspension Seat provides high containment while still allowing for easy entry and exit with its cutaway lower bolster design. It is designed to work with the factory slider without raising the seat height. The Vortex's traditional tube-style frame is mated to a laser-cut seat base which utilizes a variety of different modular mounting rails. Optional seat heaters and adjustable lumbar supports are available. The Vortex II is designed to create more legroom, steering wheel clearance, and makes getting in and out of the vehicle much easier. The Vortex II features our all-new ABS pass-throughs producing a super clean look. It also features our new PVC Sub-Belt loop which keeps your sub-belt off the floor and at your fingertips making getting strapped in a snap.
