Grill Parts Kit for Weber Genesis 300 Series - Cast Iron Grates & Bars

In this review the Grill Parts Kit for Weber Genesis 300 series is judged as a practical, no-nonsense replacement package for owners needing a reliable rebuild of their 2011-2016 Genesis models. The set is aimed at people who want a close fit to the original components and straightforward installation, and its single biggest selling point is compatibility: it is specifically made to fit Genesis 300, 310, 320 and 330 models with a front-mounted control panel, so restoring a worn grill is fast and predictable.

Key Features

• Perfect fit: The kit is designed for Genesis 300 series models including E-310, E-320, E-330, S-310, S-320, S-330 and equivalent EP/CEP/ESP variants, which reduces the need for modification during installation.
• Complete replacement set: It includes two heat deflectors, five 17.5in flavorizer bars and two cast iron cooking grids so you get all the worn internal pieces you need in one purchase.
• Durable grates: The cooking grids are heavy-duty cast iron that retain heat and promote even searing while being easier to clean than thinner alternatives.
• Porcelain-enameled bars: Flavorizer bars and heat deflectors are made from upgraded snowflake porcelain-enameled steel at 18GA thickness for greater corrosion resistance and longer service life.
• Easy installation: Parts are produced to match original mounting and dimensions so replacements go in quickly without special tools or adjustments.

Who It's For

This kit is aimed at owners of Weber Genesis 300 series grills from about 2011 to 2016 who need to replace corroded flavorizer bars, cracked heat deflectors or worn cooking grates and want a direct-fit aftermarket option. It suits backyard cooks who prefer cast iron grates for heat retention and a grill that performs like new without buying a full appliance.

People who should look elsewhere include owners of non-Genesis 300 series models or those who require OEM-branded parts for warranty reasons; also, if you want stainless steel grates instead of cast iron, this kit will not meet that preference.

Pros & Cons

Pros

• High compatibility with Genesis 300 series models makes replacement straightforward and reliable.
• Cast iron grids provide strong heat retention and improved searing compared with thin plated grates.
• Porcelain-enameled flavorizer bars and heat deflectors add durability and corrosion resistance over time.
• Customers report easy installation and clear value for money versus buying individual parts.

Cons

• Cast iron requires periodic seasoning and care to avoid rust, which is a maintenance step some users may not prefer.
• Kit is specific to Genesis 300 series and will not fit other grill families without modification.
