These mini replica locking hubs are well crafted and believable. I fit these on the front of my project bash build. They're meant to be used in place of your regular lock nut or wheel nut.
They hold well and look amazing. I remember this brand of locking hub from several old 4x4's I used to own. So the highly detailed accuracy brings back a lot of memories.
Another bonus was the mini decal assortment I received with the hubs. If you're trying to create a sense of realism for your rock, trail or fun runner then these are a great place to start.
