Genesis E-310 7524 Replacement Grill Grates - Cast Iron Heat Retention

In this review of the Genesis E-310 7524 replacement grill grates, the bottom line is simple: these cast iron cooking grids are for owners of 2007-2016 Genesis 300 series grills who want heavier, longer-lasting grates that deliver better heat retention. The reviewer found the pair to be a straightforward fit for models like E-310, S-330 and CEP-310 and praised the thicker inner metal core and matte enamel finish for producing more consistent sear marks and retaining heat across the cooking surface. This review focuses on fit, material, and everyday use rather than packaging or accessories.

Key Features

• Durable cast iron construction: The thick, solid cast iron with matte enamel holds and radiates heat for improved searing and consistent cooking.
• Wide heavy crossbars: The wider crossbars create pronounced grill marks and a sturdy cooking surface that resists warping under high heat.
• Compatible part numbers: Fits original replacement numbers such as 7524, 7528, 7566, 65937 and others used on Genesis 300 series grills.
• Correct fit for specific years: Designed to fit 2007-2016 Genesis 300 series models including E-310, E-320, E-330 and related S, EP, ESP and CEP variants.
• Two-piece set dimensions: Each grate measures about 19.5 x 12.9 in, giving a total of roughly 19.5 x 25.8 in when both pieces are installed.
• Easy to maintain when oiled: Oiling before and after use helps the enamelized surface behave like a non-stick finish and simplifies cleaning.

Who It's For

This product is aimed at owners of the Weber Genesis 300 series grills manufactured between 2007 and 2016 who need a direct replacement for worn or damaged cooking grates. It is especially useful for grillers who value stronger heat retention and distinctive sear marks that cast iron provides, and for those comfortable maintaining cast iron with routine oiling.

It is not for owners of Genesis II or Genesis II LX 300 series grills produced after 2017, and those wanting a lightweight, stainless replacement should look elsewhere. Buyers should confirm their grill year and original part number before purchasing to ensure compatibility.

Pros & Cons

Pros

• Fits Genesis 300 series models from 2007-2016 and replaces common OEM part numbers.
• Heavy cast iron core improves heat retention and helps produce even searing.
• Wide crossbars and enamel finish make the grates durable and easier to clean when oiled.

Cons

• Some reviewers noted mixed impressions of build appearance, reporting the finish does not always look as robust as expected.
• Cast iron is heavy and requires regular seasoning and care to prevent rust, which may not suit casual users.
