Precise Dimensions for GS4 Grills

Each component is engineered to exact specifications to deliver optimal performance across the cook box:

• Flavorizer Bars: 43.5 cm (Length) × 6 cm (Width) × 5.3 cm (Height)
• Heat Deflectors: 31.8 cm (Length) × 10.8 cm (Width)

This sizing ensures full coverage for even heat distribution and reliable protection against flare-ups.

Heavy-Duty Stainless Steel Construction

Crafted from durable stainless steel, these replacement flavorizer bars and heat deflectors for Weber Genesis grills are designed for demanding grilling conditions. The solid steel structure resists warping and corrosion, making them ideal for frequent, high-temperature cooking while maintaining consistent performance over time.

Reliable Flavor Enhancement & Burner Protection

The classic V-shaped flavorizer bars channel grease and drippings away from the burners, where they vaporize to infuse smoky flavor into your food. Paired with the lower heat deflectors, the system directs airflow, stabilizes heat patterns, and prevents flame blowouts to keep your cook top evenly balanced.

Package Contents & Installation

The package includes 7 × stainless steel flavorizer bars and 4 × heat deflectors for Weber Genesis 400 series grills. Installation is quick and tool-free—simply remove the cooking grates, lift out the worn components, and drop the new ones into position. Always confirm your grill model or measure your original Weber Genesis grill parts prior to ordering.
