PETKAO Genesis Grill Parts for Weber Genesis 300 Series Front-Control — Cast-Iron Grates & Stainless Burners

PETKAO Genesis Grill Parts kit is a complete replacement set made to restore Weber Genesis 300-series grills (front-control models) with grates, flavorizer bars, burner tubes and heat deflectors.

If your Weber Genesis 300-series grill (models like E310, E320, E330, S310, S330 and equivalent model numbers from 2011–2016) needs refreshed cooking surfaces or worn burners, this PETKAO kit supplies the matched parts to bring it back to reliable, even heating. The kit bundles five porcelain-enameled flavorizer bars, two matte-enamel cast-iron grates, four stainless steel burner tubes and two heat deflectors sized to replace the original Genesis 300 components.

What exactly comes in the PETKAO Genesis replacement kit?

The kit is packaged as a full service set so you can replace multiple wear items at once. Each piece is sized to align with the original Weber part fitment for 300-series front-control grills.

• 5 flavorizer bars (snowflake porcelain-enameled steel) — 17.5" L x 2.3" W x 2.2" H each
• 2 grill grates (matte enamel cast iron) — each grate 19.5" x 12.9"; total coverage 19.5" x 25.8"
• 4 stainless steel burner tubes — 19.5" long, 1" diameter each
• 2 heat deflectors — 13.25" x 8.75" each; intended as replacements for original Weber part numbers

How do these replacement parts affect grilling performance?

Upgraded surface materials help heat transfer and durability without changing how your grill operates. The matte cast-iron grates hold heat for better searing while porcelain-enameled flavorizer bars protect burners and create even vaporization of drippings.

• Cast-iron grates heat quickly and retain temperature for sear marks.
• Porcelain-enameled flavorizer bars resist rust and help distribute drippings as smoke.
• Stainless steel burners resist corrosion and restore consistent flame patterns.
• Heat deflectors direct and shield heat for uniform cooking zones.

Which Weber models will this PETKAO kit fit and which will it not?

The kit is designed specifically for 3-burner and some 4-burner Weber Genesis 300-series grills with front-mounted control knobs made roughly between 2011–2016. It does not fit the newer Genesis II 300 or Genesis II LX series.

• Compatible: Genesis 300-series front-control models (E310, E320, E330, S310, S330, EP-310/320/330).
• Not compatible: Genesis II 300, Genesis II LX series.
• Check your grill model number and compare original part sizes before purchasing.

What are the materials and durability expectations for each part?

Materials were chosen to balance longevity with heat performance. Snowflake porcelain enamel and matte cast iron are both proven for grill environments; stainless steel burners resist pitting and deformation from flame exposure.

• Flavorizer bars: thicker porcelain-enameled steel for corrosion resistance and lifespan.
• Grates: matte enamel cast iron for rapid heating and robust searing.
• Burners: stainless steel to minimize rust and maintain flame distribution.
• Heat deflectors: enamel-coated steel sized to replicate factory airflow and protection.
