Pintle hitches are powerful hooks with strong loops that attach to the rear of a towing vehicle. Used for heavy-duty towing or on rough terrains, these hitches are used when a flexible link or swivel motion is required. Tow hooks are used in groups or pairs to attach to disabled vehicles for easier movement. Stronger than chains or straps, hooks attach to vehicle frames to recover broken down or stuck vehicles. Tow ball mounts work with receivers to set the height of the vehicle being towed. Mounts fasten with a pin and clip to attach a ball hitch for towing trailers.
