Upgrading the grille on your SUV is a relatively easy way to give the front end a brand-new look. What is especially nice about installing a grille is that, depending on your taste, the new unit does not have to be very expensive and can be installed in a couple of hours or less. The options when choosing a grille are nearly as vast as wheel and tire choices. The determining factors are personal tastes and price limitations.
Trenz Manufacturing in Bakersfield, California, makes a wide array of billet aluminum products, including bumpers, interior and exterior styling accessories, steering wheels, exhaust tips, and grilles. The company's grilles are made from 6061 T-6 aircraft aluminum and undergo a three-step powdercoating treatment for a chip-free surface. There is also an eight-step hand-polishing procedure before the grilles leave the factory.
We followed along as Glenn Gruettke at Trader's in Whittier, California, installed a Trenz billet grille on a 2001 GMC Yukon. The installation took less than two hours. This aftermarket grille does not come with GMC badging, but Trenz offers a billet emblem for the piece.
