DcYourHome replacement grill parts kit for Weber Genesis 300 Series (2011–2016) — cast-iron grates & porcelain-enameled flavorizer

Full replacement kit of cast-iron grates and porcelain-enameled flavorizer bars engineered to fit Weber Genesis 300 Series grills made from 2011–2016.

If your Genesis E/S 300-series grill (front-mounted control panel) shows worn grates or rusted heat plates, this DcYourHome kit supplies the main cooking surfaces needed to restore even heat and reliable performance. The set replaces the original 7524/7621-style components and is built from heavier, longer-lasting materials than typical OEM parts, while remaining compatible with a wide list of 2011–2016 Weber Genesis models.

Will these parts fit my specific Weber Genesis model?

These components are made to match the dimensions and attachment points of Weber Genesis 300 Series grills manufactured between 2011 and 2016 with a front-mounted control panel. They are not compatible with Genesis II, Genesis II LX, or newer 2022+ Genesis models (including the 325 series).

• Compatible examples: Genesis E-310, E-320, E-330, S310, S320, S330, EP/CEP 310–330 series (2011–2016).
• Check your model number and production year on the grill’s data plate before purchase.
• Not compatible with Genesis II or Genesis (2022+) family — do not order for those grills.

How do these replacement grates and heat plates improve cooking?

The kit combines heavy-duty cast-iron grates for superior heat retention with thicker, porcelain-enameled steel flavorizer bars to protect burners and promote even vaporization of drippings. That pairing yields better searing, more consistent temperature across the cooking surface, and longer service life compared with thin factory parts.

• Cast-iron grates (2 pieces) measure 19.5 x 12.9 inches each for consistent sear marks and heat hold.
• Five porcelain-enameled heat plates (17.5 x 2.25 x 2.4 inches) resist corrosion and deflect drippings evenly.
• Thicker 18-gauge steel flavorizer bars provide added strength over standard replacements.

What materials and maintenance should I expect?

Grates are heavy-duty cast iron for maximum heat capacity; flavorizer bars are porcelain-enameled steel to resist rust and simplify cleanup. Routine maintenance—light brushing and periodic seasoning for the cast iron—keeps performance optimal without special tools.

• Cast-iron grates should be oiled and heated occasionally to maintain a non-stick surface.
• Porcelain-enameled bars wipe clean and tolerate high temperatures without flaking when used properly.
• Replace individual parts as needed; the kit supplies both grates and all five plates for a complete refresh.

How do I install the kit and what’s included?

Installation is typically straightforward: lift out old grates and heat plates, then set the new cast-iron grates into the same ledges and position each enamel plate over the burners. No special tools required for most Genesis 300 models with the front-mounted control panel.

• Included: 2 cast-iron grates (19.5 x 12.9 in each) and 5 porcelain-enameled steel heat plates (17.5 x 2.25 x 2.4 in each).
• Measured to match original OEM dimensions for 2011–2016 Genesis 300 Series fitment.
• Instructions: remove old parts, clean interior, set new plates and grates in place, test burners on low first.

Who is this for? Grill owners with a 2011–2016 Weber Genesis 300 Series who want durable, higher‑quality replacements for worn cooking surfaces. It’s suited for backyard cooks who value consistent searing, easier cleanup, and an affordable route to extend the life of their existing Weber grill without purchasing a new unit. Verify your model and control-panel orientation before ordering to ensure compatibility.
