How do these parts improve grill performance?

Replacing tired flavorizer bars, heat deflectors, and burners restores the grill’s ability to vaporize drips, distribute heat evenly, and keep flames focused under the cooking area. New parts reduce hot spots and diminish grease ignition, producing steadier temperatures and more reliable cook results.

• Porcelain-enameled flavorizer bars protect burners and create flavorful drippings.
• Stainless heat deflectors shield the firebox floor and improve heat dispersion.
• Replacement burner tubes restore even flame patterns across all three burners.
• Durable finishes resist rust and extend the service life of each component.

What are the materials and dimensions included?

The kit mixes porcelain-enameled steel and stainless steel parts sized to fit 3-burner Genesis GS4 models. Package contents include five flavorizer bars, three heat deflectors, and three tube-shaped burners, with clear length and width measurements to confirm fitment before installation.

• Flavorizer bars: porcelain-enameel steel, approx. 17 1/8" L x 3" W x 2 1/8" H each.
• Heat deflectors: stainless steel, approx. 12 1/2" x 4 1/4" each.
• Burner tubes: stainless steel, approx. 19 1/2" L each with adjustable air shutter.

How easy is installation and maintenance?

These are direct-replacement parts intended for straightforward swap-in installation using basic tools. Most owners can replace the flavorizer bars, deflectors, and burners with minimal disassembly of the cooking grate and burner assembly, returning the grill to service quickly.

• Simple remove-and-replace process—no welding or modification required.
