QuliMetal Weber Genesis II 300 Series Grill Parts – Cast Iron Grates, Flavorizer Bars & Heat Deflectors

Overview

Upgrade your Weber Genesis II cooking with a purpose‑built kit from QuliMetal. Specifically designed for Genesis II 300 Series and Genesis II LX 300 Series (2017 and newer), this set combines heavy‑duty cast iron grates, Snow Point coated flavorizer bars, and porcelain steel heat deflectors. The result is a durable upgrade that supports robust searing, steadier heat, and easier cleanup, while preserving the distinctive Genesis II grilling experience.

Why this kit may matter

Each component is chosen to balance performance and longevity. The cast iron grates deliver strong heat retention for bold sear marks, with a flat, wide slat design that helps reduce food drop‑through. Snow Point flavorizer bars provide a high‑heat shield and a subtle smoky hue to foods, while the porcelain enamel finish resists chipping under frequent use. The heat deflectors help protect burners and promote a more even heat distribution across the cook surface.

• Durable cast iron grates support steady, even heating and searing potential.
• Snow Point porcelain enamel coating on flavorizer bars stands up to high heat and adds flavor notes.
• Porcelain steel heat deflectors shield burners while guiding heat across the grate.
• Designed for repeated grilling with easy maintenance and natural non‑stick performance when lightly oiled after use.

Dimensions and package contents

Care, maintenance, and usage tips
