Genesis II E-310 Grill Replacement Parts - Durable Matte Enamel Cast

In this review of the Genesis II E-310 Grill Replacement Parts set, the bottom line is simple: this kit is for owners who want heavier, longer-lasting cooking surfaces that restore an older grill's performance. The reviewer found the matte enamel cast iron grates and porcelain steel flavorizer bars and heat deflector deliver more even heat and a refreshed look while fitting the Genesis II 300 series models. Installation is straightforward and the parts feel substantial, which makes this a practical replacement for someone focused on improved heat retention and an upgraded cooking surface.

Key Features

• Upgraded solid rods: Heavier and larger diameter solid rods on the grates increase durability and give a firmer cooking surface for searing.
• Matte enamel cast iron grates: The cast iron construction improves heat retention and helps food develop a better sear compared with thin steel grates.
• Even heat distribution: The design spreads heat more evenly across the cooking area so food cooks consistently without hot spots.
• Porcelain steel flavorizer bars: These bars protect burners from drippings and produce a smoky flavor while vaporizing juices.
• Replacement heat deflector: The included porcelain steel deflectors shield the burner and help maintain stable indirect cooking temperatures.

Who It's For

This set suits owners of Weber Genesis II 300 series grills (model years 2017-current) and compatible Genesis 300 series with front control knobs (2022 and newer) who want a heavier, more heat-retentive grate and full replacement of flavorizer bars and heat deflectors. It is especially useful for users who want to restore the look of an older grill and gain more even cooking performance.

Those who should look elsewhere include owners of older Genesis models labeled without "II" (model years 2007-2016) and buyers seeking stainless steel parts or ultra-long-life commercial components; the matte enamel and porcelain surfaces require routine care to maintain appearance and longevity.

Pros & Cons
