Why Royalty Core Is The Choice Brand For Sierra Truck Grilles

As an industry leader in custom truck grille manufacturing, Royalty Core delivers the ultimate look for your GMC Sierra 2500 or 3500 truck dating back to 2003. All Royalty Core grilles are designed with style and durability in mind and engineered to provide maximum protection for your Sierra truck. The following features set Royalty Core grilles apart from the rest:

  • Corrosion-resistant 100% T304 stainless steel: There’s no plastic in your grille, and it will never rust. In fact, T304 stainless steel is the best material to use in truck grilles because it's incredibly durable and long-lasting, but many custom grille manufacturers avoid it because it's hard to bend or mold. Royalty Core, however, has the tools and expertise to bend T304 stainless steel with precision. As a result, all Royalty Core grilles last forever and are able to protect your radiator and other parts from road debris or anything else that strikes your grille.
  • Cut with CNC precision: This guarantees precise fitment for your Sierra model. Pair that with the fact that Royalty Core grilles have twice as many attachment points as those found on their competitors' grilles, meaning you've got a grille that feels like it's always been a part of your truck.
  • Expert craftsmanship: Each grille is hand fabricated to ensure top-quality construction.
  • A rigorous testing process: Royalty Core engineers thoroughly test each grille for protection and performance with salt, chemicals, and rough off-road driving. They also tweak the design until the grille passes their strict standards.
  • Structural integrity: Royalty Core grilles offer exceptional protection against road debris. With a Royalty Core grille on your Sierra truck, you have the peace of mind that your radiator and engine compartment are safe from heavy impacts. Also, each Royalty Core grille comes with a lifetime warranty.

You can customize your Royalty Core grille to give it a distinct, personalized look that sets your Sierra truck apart from the rest. You can choose from dozens of custom configurations for each grille, such as:

  • Mesh sizes and finishes
  • Grille frame finishes
  • Accent stud finishes or removal
  • Integrated or add-on accents, such as custom emblems or LED light bars

It's no wonder many Sierra truck owners consider Royalty Core the best brand for aftermarket grilles.
