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. The plus to this is these factory bolt holes have been tested by the manufacture and are the safest way to install your harness belts. 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. For added comfort, each harness belt is made with a pressure reducing waist pad. The 4-Point Harness Belts come in either bolt-in or snap-in mounting. With bolt-in mounting, the ends of the straps bolt into your mounting location. With snap-in mounting, eye bolts are included that bolt into your mounting locations. The ends of your harness straps then snap to those eye bolts. Two inch harness pads are also recommended to prevent the shoulder straps from rubbing your neck. The part numbers for the 4-Point, 2" Harness belt are as follows: 44001B: Black 4-Point Bolt-In, 44001S: Black 4-Point Snap-In, 44003B: Yellow 4-Point Bolt-In, 44003S: Yellow 4-Point Snap-In, 44005B: Blue 4-Point Bolt-In, 44005S: Blue 4-Point Snap-In, 44007B: Red 4-Point Bolt-In, 44007S: Red 4-Point Snap-In.
