AJinTeby Grill Replacement Kit for Weber Genesis II 300 Series (2017+) — 2 Porcelain-Coated Cast Iron Grates, 5 Flavorizer Bars

AJinTeby replacement kit renews Weber Genesis II 300 Series grills (2017 and later) with two porcelain-enameled cooking grates, five flavorizer bars, and three heat deflectors for restored performance.

If your Weber Genesis II 300 Series grill is showing uneven heating, stubborn rust, or worn flavorizer bars, this complete parts kit refills the most commonly replaced components in one purchase. The set is designed to match the dimensions and mounting style of Genesis II models (E-, S-, SE-, LX-series) from 2017 onward. All components use durable materials to resist high heat and outdoor corrosion while keeping maintenance simple.

Will these parts fit my Weber Genesis II 300 Series grill?

Yes—this AJinTeby kit is tailored for Genesis II 300 Series models produced 2017 to present. Confirm your grill’s control panel reads “GENESIS II”; older Genesis (pre-2017) panels without “II” are not compatible.

• Compatible with E-310, E-315, E-325, E-330, E-335, E-345 models.
• Also fits S-310, S-315, S-325, S-335, S-345 and SE/LX variants listed in the specs.
• Matches OEM-style dimensions (each grate 18.8 x 13.25", combined 18.8 x 26.5").
• Not for Genesis models manufactured 2007–2016 that lack "II" marking.

What materials are used and how long will they last?

The cooking grates are heavy-duty cast iron finished with a porcelain enamel coating, while the flavorizer bars and heat deflectors are solid porcelain-enameled steel. Those materials are chosen for heat retention, rust resistance, and durability in backyard grilling conditions.

• Porcelain-enameled steel flavorizer bars resist corrosion and flare-ups.
• Cast iron grates hold heat for better searing and even cooking.
• Heat deflectors protect burners and distribute heat across the cooking area.
• Designed to withstand repeated grill cycles when cleaned and seasoned properly.

How easy is installation and maintenance?

Installation takes only minutes and uses the existing mounting points in your Genesis II 300 Series grill. The smooth, enamel surfaces clean easily with a brush or mild detergent, and the cast-iron grates respond well to routine seasoning to maintain their nonstick properties.

• Quick swap-in: remove old parts and set the new pieces into place—no special tools required.
• Nonstick enamel wipes clean; soak and scrub for heavier residue.
• Season cast-iron grates after cleaning to prevent sticking and rust.
• Inspect flavorizer bars periodically for heavy wear and replace as needed.

What exactly is included in the package and what are the dimensions?

The kit contains two cooking grates, five flavorizer bars, and three heat deflectors sized to match Genesis II 300 Series specifications. Dimensions are provided so you can double-check fit against your grill before purchase.

• 2 cooking grates: each 18.8 x 13.25", combined coverage 18.8 x 26.5".
• 5 flavorizer bars: 17.1" L x 3" W x 2" H each.
• 3 heat deflectors: 12.5" L x 4.25" W each.
• Packaged to protect enamel finish during shipping.

Who is this for: Grillers with a Weber Genesis II 300 Series (2017+) who want an affordable, OEM-style refresh rather than replacing the entire grill. This kit is ideal for homeowners who need reliable heat distribution, want to improve searing performance, and prefer parts that are straightforward to swap and maintain. It’s also a useful spare-parts bundle for rental properties, vacation homes, or anyone who entertains frequently and depends on consistent grill performance.
