Corbeau 4-Point, 2" Harness Belts are an affordable way to upgrade your vehicle to harness belts. As with all Corbeau harness belts, the lap belts bolt to your factory bolt hole locations. With a 4-Point Harness Belt, the two shoulder straps go over your shoulders and through the harness slots in your seats. After they go through the harness slots these straps then mount in the rear area of your vehicle.
