Weber Genesis II E-410 Grill Grates Replacement - Heavy Cast Iron

Our review of these replacement grill grates finds them best suited to owners of the Weber Genesis II 400 series who want a durable, heavy-duty cooking surface. The single biggest reason to buy is the upgraded cast iron construction with thicker, larger-diameter solid rods that hold and distribute heat far better than thin or chipped porcelain-coated grates. For anyone who sears frequently or wants longer-lasting grates that resist coating failure, these are a practical replacement option that fits many Genesis II E-410, S-410, SE-410 and related models.

Key Features

• Upgraded heavier solid rods: Thicker cast iron rods provide extra mass for stable, long-term use and reduced warping under high heat.
• High heat retention: Cast iron construction retains heat well to deliver even heat distribution and faster searing performance.
• Three-piece set: Comes as three cast iron cooking grates sized to replace the factory setup for Genesis II 400 series grills.
• Model compatibility: Designed to fit a wide range of Genesis II 400 and LX 400 series grills including E-410, E-415, E-435 and S-435 variants.
• Maintenance guidance: Manufacturer recommends oiling the grates before and after use and avoiding metal tools to extend grate life.
• Original part compatibility: Cross-references common Weber part numbers such as 66097 and 66089 for easy identification.

Who It's For

This set is ideal for grill owners who frequently sear steaks or use high-heat grilling and need grates that maintain temperature and withstand heavy use. It appeals to shoppers looking to replace chipped or worn porcelain-coated grates with a solid cast iron option that can be re-seasoned and maintained.

It is not the best choice for users who prefer a low-maintenance porcelain finish that requires less regular oiling, or for owners of non-compatible Weber models - always verify your grill model and serial number before ordering or contact the seller for confirmation.

Pros & Cons

Pros

• Durable cast iron construction improves searing and holds heat evenly.
• Thicker, larger-diameter rods resist chipping and feel heavy-duty compared with thin grates.
• Three-piece set matches the original cooking surface layout for compatible Genesis II 400 series grills.
• Cross-references common Weber part numbers for easier model matching.

Cons

• Requires regular oiling and care to prevent rust and maintain seasoning, so it is higher maintenance than porcelain-coated grates.
• May not fit if the grill model or year does not match-confirm model numbers before purchase.
