Some things just have to be double shear and these are two applications that are a must! These brackets provide a secure method of attaching seat belt harnesses to your vehicle. Need to limit down travel for your new coilovers or air shock? These can work great in that application as well. These double shear brackets have a ¼ gap and measure 1 5/16 from the center of the ½ mounting hole to the bottom of the bracket. These are sold in pairs.
