Uniflasy Replacement Flavorizer Bars & Heat Deflectors for Weber Genesis II 300-Series — Snowflake Black Porcelain, 5 Bars + 3 Def

Uniflasy replacement flavorizer bars and heat deflectors restore even heat, protect burners, and revive smoky BBQ flavor for Weber Genesis II 300-series grills.

If your Weber Genesis II or Genesis II LX 300-series grill is showing uneven heat, exposed burners, or worn vaporizer bars, this Uniflasy set provides a direct-fit replacement for part numbers like 66032, 66795, 66040, and 66685. Built to OEM-compatible dimensions and finished in a durable snowflake-black porcelain enamel, the kit includes five porcelain-enameled flavorizer bars and three heat deflectors engineered to match GS4 models from 2017 and newer. The thicker 16-gauge steel construction increases stability and longevity compared with many aftermarket 17GA/20GA options.

Which Weber models will these Uniflasy parts fit?

These components are designed specifically for Weber Genesis II 300 Series and Genesis II LX 300 Series grills from 2017 onward. They cover a wide range of model codes across E-, S-, SE-, and LX-series ovens, making them a practical replacement for many common GS4 setups.

• Compatible with Genesis II E-310, S-310, SE-310, E-315, E-325, E-330, SE-330, CE-330, S-335, SE-335, E-335, S-345.
• Also fits Genesis II LX models like LX S-340, LX E-340 and related CSS/CSE 315/335/340 variants.
• Verify grill model year and compare original part sizes before purchase to ensure a precise fit.

How do these bars and deflectors change grilling performance?

By vaporizing drippings and evenly redirecting heat, the flavorizer bars help reduce hot spots and add smoky, caramelized notes to food without exposing burners to direct flare-ups. The heat deflectors further stabilize temperature across the grate and protect sensitive burner tubes from grease and flames.

• Porcelain-enamel surface promotes drippings-to-vapor transformation for richer flavor.
• Even heat distribution minimizes temperature variance across the cooking area.
• Protects burners from direct flame, extending their service life and reducing flare-ups.

What are the dimensions, materials, and finish details?

Uniflasy matches OEM sizing to simplify installation: five full-length flavorizer bars and three shorter heat deflectors form a complete replacement package. Constructed from 16GA steel and coated with a specially formulated snowflake-black porcelain enamel, the components emphasize durability and ease of cleaning.

• Flavorizer Bars (5): 17 1/8" L x 3" W x 2 1/8" H; Heat Deflectors (3): 12 1/2" L x 4 1/4" W.
• 16-gauge steel construction (~5.43 lbs total) for improved rigidity and heat tolerance.
• Snowflake porcelain-enamel finish resists corrosion, grease buildup, and chipping.

How do I install and maintain these replacements?

Installation is a straightforward swap: remove the old flavorizer bars and heat deflectors, compare sizes, then place the new Uniflasy pieces into the same slots. The porcelain-enamel surface wipes clean easily; brief periodic maintenance keeps performance consistent season after season.

• Simple remove-and-replace process—no special tools required for most models.
• Wipe with warm soapy water after cooling; avoid abrasive cleaners that harm enamel.
• Inspect periodically for heavy corrosion or warping and replace as needed.

Who is this for: This Uniflasy replacement set is ideal for owners of Weber Genesis II and Genesis II LX 300-series grills (2017 and newer) who need OEM-sized flavorizer bars and heat deflectors that last longer than typical thin-gauge aftermarket parts. Choose this kit if you want improved heat consistency, burner protection, and a porcelain-enamel finish that cleans easily while restoring that classic grilled flavor. Always confirm your grill model and original part measurements before ordering to ensure compatibility.
