Chevrolet's newest offering in the truck category is the '07 Silverado. This truck features an all-new sheetmetal and grille design that, in our opinion, is a perfect canvas to customize. Because we are custom freaks, we just had to see one of these trucks sporting a billet grille. T-Rex has a full billet overlay grille that requires no cutting to install and looks pretty sweet. The grilles are constructed out of T-6 billet aluminum, which has been TIG-welded in a custom jig to ensure nice straight lines. They will come to you completely powdercoated black, except for the face, which will be polished to a nice luster. The crew at SoCal SuperTrucks took a small break during the suspension lift to install the T-Rex bars.

In the before and after shot, you can see how accepting the new Silverado is to a billet grille. That added piece of flash ties in nicely with the huge chrome bumper and gives the front end a little more continuity. The lower bumper filler is sold separately, just in case you've installed some sort of bumper cover. | 
Fear not GMC owners, T-REX has a billet grille setup for you guys, too. Just because you bought Professional Grade doesn't mean you can't have custom. |
To get these inserts in place, the main grille assembly needs to be removed. Step one in that process is to remove the radiator cover by popping out the plastic fasteners. | 
Under that, you will find four 10mm bolts and six metal clips. Use a ratchet to take out the bolts, and a long flat-tip screwdriver should make quick work of the clips. | 
Here is the hardware from T-Rex for both the upper (R) and lower (L) grille inserts. |
 | 
The upper grille installs by placing the billet bars in the proper opening and tightening it with the provided hardware. | 
The lower insert installs via two Phillips head screws onto two L-shaped brackets that mount into two existing holes on the truck. |
The Final Word
There is nothing simpler or more visually beneficial than a billet grille installation. This is probably the first mod a new truck owner should do; it's a great start down custom street.
