Leship 17.5 in Cast Iron Grill Grates for Weber Spirit & Genesis

In this review of the Leship 17.5 in cast iron grill grates, the bottom line is simple: these are a practical replacement for owners of older Weber Spirit and Genesis gas grills who want stronger searing performance and a close fit to original parts. The reviewer found the grates heavy, well machined, and able to recreate deep sear marks on steaks while retaining heat well. They are aimed at someone replacing worn or missing grates and who values durability and heat retention over a nonstick coated surface.

Key Features

• Exact fit to many Weber models: Designed to replace original part numbers like 7638 and fit Spirit 300 series, Spirit II GS4 E-310/S-310, Genesis 1000-3500 and related models for straightforward installation.
• Cast iron construction: Thick cast iron distributes and holds heat so grills reach steady searing temperatures and produce pronounced grill marks.
• Set of two grates: Each grate measures 17.5 in x 11.9 in, giving a combined cooking surface of roughly 17.5 in x 23.8 in for dual-burner configurations.
• Replacement versatility: Works as a substitute for multiple Weber replacement codes across Spirit and Genesis ranges, making these useful for older grills where originals are discontinued.
• Durability focus: Heavy duty build suggests long service life when maintained, and customers report the grates feel more robust than some original OEM pieces.

Who It's For

These grates suit owners of compatible Weber Spirit 300 series, Spirit II GS4 E-310/S-310 and many older Genesis gas grills who need a like-for-like replacement that improves searing. They are ideal for backyard cooks who want to restore consistent heat and produce visually appealing sear marks on steaks or burgers.

Users who prefer an enamel-coated or stainless surface for minimal maintenance should look elsewhere, since cast iron requires seasoning and occasional rust prevention. Also confirm your grill model and current grate dimensions before buying to ensure compatibility.
