X Home 19.5in Grill Grates Replacement for Weber Genesis 300 Series

In this review the reviewer tested the X Home 19.5in grill grates as a direct replacement for older Weber Genesis 300 Series models (2007-2016). The bottom line: these cast iron grates are for cooks who want a heavy-duty, true replacement that restores sear and heat distribution to an E-310/E-320/E-330 style grill. Fit and cooking performance are the single biggest reasons to buy - they match the original part footprint and bring back the thicker bars needed for searing. This review focuses on fit, material, and everyday use rather than cosmetic details.

Key Features

• Perfect fit: Cut to the same dimensions as original part# 7524 so they sit correctly in Genesis 300 Series (2007-2016) grills without modification.
• Cast iron construction: Heavy-duty cast iron spreads heat more evenly across the cooking surface for better sears and consistent cooking.
• Two-pack convenience: The set includes two grates covering 19.5 x 25.8 in total so you replace the full cooking area in one purchase.
• True sear capability: The thick bars create pronounced grill marks and help develop the char and flavor associated with cast iron grates.
• Value replacement: Customers report these as cost-effective replacements that restore original cooking performance and feel.

Who It's For

This product is aimed at owners of the Weber Genesis 300 Series grills manufactured between 2007 and 2016, including E-310, E-320, and E-330 models who need a full replacement set of cooking grates. It is best for home cooks who prioritize heavy-duty materials and want to recreate the original searing and heat retention of their grill.

Those who should look elsewhere include owners of Genesis II or LX 300 Series grills (2011 and newer) because those models require smaller 18.75in grates. Also buyers seeking stainless or enamel-coated grates for lower maintenance should consider other finishes, as these are uncoated cast iron.

Pros & Cons

Pros

• Good fit for the specified Genesis 300 Series models, matching the original part dimensions.
• Heavy cast iron construction delivers even heat distribution and strong sear marks.
• Sold as a two-pack so the entire cooking surface is replaced in one purchase.
• Reported as good value by customers compared with buying OEM replacements.

Cons

• Uncoated cast iron can develop surface rust if not properly seasoned and maintained.
• Not compatible with Genesis II/LX 300 Series grills that require 18.75in grates.

Our Verdict

The X Home 19.5in cast iron grates are a sensible, cost-effective replacement for owners of older Genesis 300 Series grills who want to restore original searing performance and heat distribution. They deliver solid value and durability when seasoned and maintained, but buyers should confirm grill model compatibility and be prepared for the maintenance required with uncoated cast iron.
