If the wheel studs for the Equinox are the same as the Terrain, they're 14mm x 1.5. I'm not sure where you would buy them locally, but summit racing has them if you want to buy from them directly. Or you can order them from ebay. Just a quick check and I found the following locks: item #370342329672 sold by summit racing. Mcgard also makes locks, which you may find locally at Pep Boys or some place like that.muzzyc6 said:Has anyone installed wheel locks on 19" factory chrome wheels. Am having hard time locating correct lock for my LTZ equinox.
