Boltover grilles are also called bolton, slap on and EZ  billet grills in after market grille industry. They are the easiest, least time-consuming to install. Rather than completely replacing your existing grill work, a Bolt Over Billet Grill sits right on top of your existing one. These have pre-attached hidden bolts and use brackets and locknuts for a solid, secure and simple installation. They require no drilling or cutting of any kind. Bolt over grilles suit the buyer who can't modify their vehicles(such as they lease the vehicle and have to return in a certain time) or who don't feel comfortable to do any modifications to their vehicles. The shortcoming for boltover grilles is you may see the factory grille underneath the billet grille from a close distance. But it will be not noticeable when you drive on the road.

There are two types of boltover grilles in the market. They are identified by their installation methods. One is mounted by bolts and nuts which come with the grille as a hardware kit. We are selling this type of boltover grilles. Some sellers use zipties to tie the billet grilles on the factory grilles. The tie will turn loose after driving for a while.
