For years Precision Grilles has made grilles that mount over factory grille shells, mostly without cutting or drilling. Demand is now so high that EZ categories were created so you could find applications easier. EZ Grilles offer the installer a choice for the vehicle's final appearance: Install the grille over the existing shell, which often exposes the shell partially through grille spaces, or use a body saw to trim the shell so it is not visible through the grille after installation. The key difference between EZ Billet and EZ Solid is that EZ Solid Grilles are CNC-machined from a solid plate of 6061-T6 aircraft-grade aluminum. Many in both categories are available for bumper and upper grilles.
