WEMEIKIT 17" Flavorizer Bars for Weber Genesis II 300/LX-300 - 5-Pack, 16GA Porcelain-Enameled Heat Guards

These WEMEIKIT 17-1/8" porcelain-enameled 16GA flavorizer bars are heavy-duty replacement flame guards designed to restore even heat, vaporized-flavor and burner protection for Weber Genesis II 300 and LX-300 grills.

If your Genesis II E/S-310, E/S-315, E/S-330, E/S-335 or LX E/S-340 grill is missing or rusting its flavorizer bars, this five-pack gives you a like-for-like replacement built thicker and heavier than many aftermarket options. Each bar is shaped to the original profile, finished with a smooth porcelain enamel, and includes the two semicircular cutouts found on the OEM part so burners are visible and airflow is preserved. The set is sized to fit 2017 and newer Weber Genesis II 300-series models that accept the 17-inch bars; it is not compatible with Genesis I or side-mount control variants.

How do these bars improve my grill’s performance?

These flame guards protect burners from drippings while converting grease into flavorful smoke, which enhances taste and helps maintain consistent heat across the cooking surface. Because they’re heavier and thicker (16GA) than many replacement pieces, they deliver better heat distribution and longer service life.

• Thicker 16-gauge steel improves heat retention and resists warping.
• Porcelain enamel provides corrosion resistance and easy cleaning.
• Semicircular cutouts let you inspect burner flames and keep airflow steady.
• Heavy weight (about 1.21 lb each) helps stabilize even heating.

Will these fit my Weber Genesis II 300 or LX 300 grill?

Measure your existing flavorizer bars and compare to these dimensions to confirm fit: 17-1/8" long, 3" wide, and 2-1/8" high. The shape and cutouts match the OEM 66795/66032 profile, so they fit 2017+ Genesis II 300 and LX 300 series models listed by Weber that accept this bar length.

• Compatible with Genesis II: E-310, S-310, E-315, S-315, E-330, S-330, E-335, S-335.
• Compatible with Genesis II LX: E-340, S-340 (2017 and newer).
• Not compatible with Genesis I series or grills with side-mounted controls.
• Pack includes five bars—enough to replace a full cooking area set.

How are these bars built and how long will they last?

WEMEIKIT forms these bars from solid cast-style steel before sintering a durable porcelain enamel coating. The manufacturing produces a smooth, dark finish that stands up to high temperatures and frequent use. While lifespan depends on care and exposure, the thick steel and enamel extend usable life compared with thin, uncoated copies.

• Constructed from 16GA steel and porcelain-enameled for heat and corrosion resistance.
• Each bar weighs roughly 1.21 lb; total pack weight about 6.06 lb.
• Smooth enamel finish simplifies scraping and routine cleaning.
• Designed to reproduce smoky flavor by vaporizing drippings effectively.

How do I install and maintain these flavorizer bars?

Installation is straightforward: remove old or damaged bars, slide the new bars into the factory slots, and verify burner access through the semicircular openings. Routine maintenance includes brushing off ash and grease after cooling and occasional deeper cleaning to prevent heavy buildup that can damage the enamel.

• Turn grill off and cool completely before replacing bars.
• Slide each 17-1/8" bar into the existing supports—no modifications required if matched correctly.
• Clean with a grill brush and warm soapy water; avoid harsh abrasives that damage enamel.
• Inspect burners when reassembling to ensure proper flame and spacing.

Who is this for: This five-pack is ideal for Genesis II 300-series and LX 300 owners who want OEM-style performance with extra durability—home grillers who cook frequently, restore an older grill to like-new condition, or replace corroded flame guards with a heavier, porcelain-enameled option. If you’re unsure about compatibility, measure your current bars (17-1/8" x 3" x 2-1/8") and check your grill model year to confirm fit.
