In this review the replacement kit for the 2011-2016 Weber Genesis 300 Series is evaluated for everyday grill owners who want durable, better-performing cooking surfaces. The kit replaces worn grates and heat plates with two heavy-duty cast iron grates and five porcelain-enameled flavorizer bars, offering improved heat retention and a more consistent sear. For anyone with a front-mounted control panel Genesis 300 from 2011 to 2016, this kit is a straightforward, value-minded repair that restores cooking performance without needing a whole new grill.

Key Features

• Exact fit for Genesis 300 Series: Designed specifically for 2011-2016 Genesis models with a front-mounted control panel, so installation aligns with original mounting points.
• Heavy-duty cast iron grates: The two cast iron grates provide strong heat retention and even searing that improves browning and grill marks.
• Upgraded porcelain-enameled bars: Five flavorizer bars use thicker 18GA enamel steel to resist corrosion and protect burners while adding smoky flavor.
• Complete replacement set: The kit includes two 19.5 x 12.9 in grates and five 17.5 x 2.25 x 2.4 in bars to fully refresh the primary cooking area.
• Easy maintenance: Cast iron surfaces heat quickly and release food when properly seasoned, making cleaning and ongoing upkeep straightforward.
• Protects burners: The bars catch falling grease to reduce flare-ups and preserve burner life for more dependable performance.

Who It's For

This kit is aimed at owners of the Weber Genesis 300 Series built between 2011 and 2016 who need a like-for-like replacement of worn grates and flavorizer bars. It is best for home grillers who value durable materials, improved searing, and a restoration of original cooking performance without replacing the entire grill.

Those who should look elsewhere include owners of Genesis II or Genesis II LX models, because this set does not fit those newer frames, and buyers who prefer stainless steel grates rather than cast iron should consider alternate materials.
