Overland Vehicle System 3/4 Recovery Shackle in Zinc is heavy duty forged D ring style shackle. Each OVS shackle has a two stage powder coat. First layer is Electrostatic plated and then a heavy duty Zinc coated finish is applied which is the same process as the Original Automotive Manufactures do. The shackle has multiple uses in recovery but the most common is affixed to a bumper however for more information see below for chart of uses with a shackle. Highly recommend a at least two shackles and tow strap when off road.
