Hi guys,
Bought these for a previous car, but never got around to using them. Hung on to them knowing how rare they are but got a European car now so probably never going to be any use to me any time soon.
They are a very cool anti theft lock nut system. I had a hard time tracking a set of these down, and eventually purchased them from Nengun for approx $200. They have since stopped making them so consider them rare.
They work like a normal lock nut, but with quite a unique shape pattern. Nonetheless, like any lock nut, a committed thief can still smash a smaller sized socket over it and wind the nut off. So to prevent that these have a special cap that sits over the lock nut which can only be remove by a special magnet key.
Like anything, deterrence is the key, and while I reckon any lock nuts are removable with enough time and motivation, the ill seriously slow someone down.
They are in as new condition in original packaging.
Asking $150 posted anywhere in Oz or pick up available in Armadale Vic 3143
Here is a video explaining how they work
