Why it works:
Class V hitches handle the heaviest towing loads — gooseneck adapters, heavy-duty ball mounts, and commercial towing equipment. The dogbone style provides a secure fit in the larger 3" receiver opening that standard bent-pin locks don't cover. The included sleeve allows the 5/8" pin to fill a 3/4" receiver hole for a rattle-free, snug fit that prevents the lock from shifting during towing.
Ideal for: Heavy-duty truck and commercial vehicle owners with Class V 3" receivers who need a secure hitch lock. See also the bent pin style (DRAW019) for 2" and 2.5" Class III/IV receivers.
