These GS4 Genesis II grill parts are designed as direct replacement components for Weber three-burner models, including the Genesis II, Genesis II LX 300 series, and Genesis 300 series. The set includes Flavorizer bars (part numbers 66032 and 67095) and a heat deflector (part number 66040).

Constructed from heavy-duty stainless steel and porcelain-enameled steel, these parts are built to withstand high cooking temperatures and resist rust and corrosion over extended use. The Flavorizer bars feature a curved design that channels drippings away from the burners while vaporizing them into smoke, adding a subtle char-grilled flavor to food. The heat deflector sits above the burner tubes to distribute heat evenly across the cooking surface, reducing hot spots and flare-ups. Both components share a precise fitment that aligns with the original Weber assembly, making installation straightforward without modification. The materials maintain structural integrity through repeated heating and cooling cycles, and the porcelain coating on the deflector facilitates easier cleanup after cooking. These parts are suitable for grill owners who need reliable replacements for worn or damaged originals, offering a balance of durability and functional performance. The set provides an economical alternative to full grill replacement, restoring cooking consistency and extending the lifespan of compatible Genesis series grills. The design prioritizes simple replacement with standard tools, and the components do not interfere with normal grill operation. Owners of Weber GS4 Genesis II grills will find these parts compatible with their specific model year configurations, as referenced by OEM part cross-references. The Flavorizer bars and heat deflector work together to maintain the intended airflow and heat management system of the original grill. Using these components helps preserve the cooking characteristics that Weber grills are known for, without altering gas flow or ignition performance. The metal thickness and coating quality support typical household grilling use across multiple seasons. No special maintenance is required beyond regular cleaning of the bars and deflector.
