Grill Valueparts replacement flavorizer bars & cast-iron grates kit for Weber Genesis 300-series (2011–2016) — porcelain-coated he

Complete five-piece flavorizer bars, two heat deflectors and two cast-iron grates kit designed to replace worn parts on Weber Genesis 300-series grills with front-mounted controls (2011–2016).

If your Weber Genesis E-310, E-330, S-310 or similar 300-series grill shows uneven heating, flare-ups from clogged burners, or rusty, warped grates, this Grill Valueparts kit restores the cooking surface and burner protection. The kit contains five porcelain-coated steel flavorizer bars, two porcelain-coated steel heat deflectors and two matte-enamel cast iron cooking grates sized to match factory fittings for front-control Genesis models from 2011–2016.

How will these replacement parts improve my grill’s performance?

These components protect the burner tubes, redirect heat evenly, and add the searing surface that helps develop grill marks and smoky flavor. Replacing deteriorated parts reduces grease buildup and prevents flame interruption from clogged burner holes.

• Flavorizer bars capture drippings and vaporize juices to increase smoke and flavor.
• Heat deflectors distribute heat consistently across the cooking area.
• Cast-iron grates retain and conduct heat for reliable searing and even cooking.

Will this set fit my Weber Genesis E-310 or similar 300-series model?

The kit is sized for Weber Genesis 300-series grills with front-mounted controls made between 2011 and 2016. It replaces many OEM part numbers listed for those models, but it is not compatible with side-control 2007–2010 Genesis or Genesis II (2017+).

• Check grill model year and front-control layout before ordering.
• Included part dimensions: 17.5" x 2.25" flavorizer bars; 13.25" x 8.75" heat deflectors; 12.9" x 19.5" grates.
• Replaces multiple Weber OEM numbers for the Genesis 300 series.

What materials and durability can I expect from these parts?

The flavorizer bars and heat deflectors use upgraded porcelain-coated steel for corrosion resistance and heat management, while the cooking grates are matte-enamel cast iron for strong heat retention and longevity. Together they resist chipping and warping under normal grilling temperatures.

• Porcelain-coated steel minimizes rust and helps vaporize drippings.
• Matte-enamel cast-iron grates provide even heat distribution and searing.
• Durable construction resists cracking and deformation during regular use.

How do I install and maintain these replacement pieces?

Installation is straightforward: remove the old bars, deflectors, and grates, then set the new deflectors over the burners, align the flavorizer bars, and place the grates on top. Regular cleaning preserves performance and prevents grease buildup that can affect burners.

• Allow grill to cool, then remove old parts and wipe interior before replacing.
• Clean grates after each use and deep-clean deflectors periodically to prevent clogging.
• Inspect burners when changing parts to ensure safe operation.

Who this is for: This kit is for owners of Weber Genesis 300-series grills (front-control, 2011–2016) who need a full set of replacement burner protection and cooking surfaces. It’s ideal if you want to restore even heat distribution, reduce flare-ups, and refresh searing performance without buying OEM parts.
