Leship 19.5 in Cast Iron Cooking Grates Replacement - Fits Genesis 300

In this review of the Leship 19.5 in cast iron cooking grates, the bottom line is simple: these are a sensible replacement for owners of older Weber Genesis 300 series grills who want durable cast iron that sears well. The reviewer found them especially appealing for those who need an exact fit for 2007-2016 Genesis 300 models and who value heavy-duty construction and heat retention. The package arrives as two porcelain-coated cast iron grates that feel solid and produce the sear marks expected from cast iron cooking surfaces.

Key Features

• Exact fit for older Genesis 300 models: Designed to fit specific Genesis 300 series gas grills from 2007-2016, ensuring a proper replacement without modification.
• Porcelain-coated cast iron: The porcelain coating helps with food release while the cast iron retains heat for better searing and consistent grill marks.
• Set of two grates: Supplied as a matching pair so both halves of the cooking surface are replaced at once for even performance across the grill.
• Heavy duty construction: The grates feel robust and resist warping, which contributes to long-term durability under regular grilling use.
• Dimension clarity: Each grate measures 19.5 x 12.9 x 0.5 in so buyers can confirm fit before ordering.

Who It's For

These grates are best for owners of the older Weber Genesis 300 series (Genesis E-310, E-320, S-310, S-320, EP-310, EP-320 from 2007-2016, and certain E-330, S-330, EP-330 models from 2011-2016) who want to restore performance with cast iron cooking surfaces that sear and retain heat.

They are not for owners of Genesis II 300 or Genesis II LX 300 series grills (2017 and newer); those users should look for the alternate 18.75 in replacement. Also, if a user prefers stainless steel grates or a lighter, rust-free material, these heavy cast iron pieces may be less suitable.

Pros & Cons

Pros

• Produces prominent sear marks and holds heat well for better grilling results.
• Well-built porcelain cast iron gives a substantial, durable feel compared with some OEM replacements.
• Good replacement value because the set includes two matching grates, restoring full cooking surface consistency.

Cons

• Cast iron can begin to show surface rust if not properly maintained and seasoned over time.
• Fitment is specific to older Genesis 300 models only, so buyers must double-check model year and dimensions.
