Overview
The T-Rex Grilles X-Metal Series Formed Mesh Grille, part number 6712111, is an insert-style replacement grille for the 2015–2018 GMC Sierra 2500 HD and 3500 HD. Its formed mesh face is black powder-coated mild steel. As an insert, it sits within the grille opening rather than covering the full front of the truck.
GMC Sierra HD owners in the listed trims will find this grille relevant for a darker, mesh-style front face. T-Rex designs its line around bolt-on installation, which the brand says reduces tool needs and avoids cutting. Match your truck’s year, model and trim to the list below before ordering.
Key features
- Insert-style formed mesh design in the X-Metal Series
- Black powder-coated mild steel construction
- One-piece grille
- Direct fit for the listed 2015–2018 Sierra 2500 HD and 3500 HD trims
- Bolt-on design that T-Rex Grilles describes as needing few tools
Before you fit an insert grille
An insert grille sits inside the existing grille opening rather than covering the whole front of the truck, so the fit depends on the opening itself. Before removing the original piece, look at the opening’s edges, the mounting points and the clearance around the radiator and headlights. A mesh face that matches the opening can still sit slightly off if the surrounding frame is bent or dirty, so clean the area first.
Handle a powder-coated mesh insert by its edges and keep tools away from the face to avoid chips. Plan a steady work surface, and keep track of any clips or fasteners you remove. If the insert rattles after installation, check the seating at each mounting point before assuming a fault in the grille itself. Re-check the fasteners after the first few drives, since vibration can loosen them over time.
