Stainless Steel Flavorizer Bars and Cast Iron Grates for Weber Genesis

In this review of the Stainless Steel Flavorizer Bars, Heat Deflector and Cast Iron Grill Grates replacement set, the bottom line is simple: it is a practical, durable parts kit for owners of Weber Genesis 300 series grills (2011-2016) who need a direct-fit replacement that restores function and flavor. The reviewer found the kit especially valuable for people replacing corroded or missing flavorizer bars and grates, because the pieces are thicker and feel more substantial than typical aftermarket parts, while matching the dimensions for the Genesis 300 front-control models.

Key Features

• Perfect Fit: The set is made to match Weber Genesis 300 Propane series models from 2011 to 2016 with a front mounted control panel, which simplifies installation for those exact grills.
• Complete Package: The kit includes five stainless flavorizer bars, two stainless heat deflectors and two cast iron grates, giving a near-complete cooking surface replacement in one purchase.
• Durable Materials: The flavorizer bars and deflectors are stainless steel and the grates are heavy cast iron, providing stronger oxidation resistance and thicker construction than many low-cost alternatives.
• Heat Management: The heat deflectors and flavorizer bars help distribute heat more evenly and protect the burners from dripping oil, which also helps produce more consistent grilling results.
• Correct Dimensions: Key parts are sized specifically (flavorizer bars 17.5 in x 2.25 in x 2.375 in; deflectors 13.25 in x 8.75 in; grates 19.5 in x 12.9 in each) so buyers can verify fit before ordering.

Who It's For

This replacement set is ideal for owners of Weber Genesis E-310, S-310, E-320, S-320, E-330, S-330 and equivalent EP/CEP 300 models from 2011 to 2016 who need to replace corroded flavorizer bars, warped deflectors or worn cast iron grates. It also suits DIY-minded grill owners who prefer a single kit that covers most cookbox wear points.

Shoppers with Genesis II or Genesis II LX300 models should look elsewhere, since the product documentation warns of mismatch with those lines. Also, anyone who cannot measure their grill should confirm the listed dimensions before buying to avoid fit issues.

Pros & Cons

Pros

• Stainless flavorizer bars and heat deflectors resist rust and feel thicker than common replacements.
• Cast iron grates recover the searing surface and add heft to the cooking grate compared with thin steel options.
• The kit covers multiple wear parts in one purchase, simplifying maintenance for compatible Genesis 300 grills.

Cons

• Compatibility is limited to Genesis 300 front-control models (2011-2016) and may not fit later Genesis II series, so careful measurement is required.
• The kit does not include smaller hardware or clips that some grills use, so a buyer may need to reuse existing fasteners.
