Refresh your Weber Spirit grilling with a complete upgrade kit

The Uniflasy replacement kit combines two porcelain-enameled cast iron grates (7638) with five porcelain-enameled flavorizer bars (7636) to restore heat balance and enhance everyday grilling on Weber Spirit 300 Series and Spirit II 300 Series grills with front-mounted control panels. By upgrading both grates and bars in one bundle, you can refresh heat performance and cooking results without replacing the entire grill.

What’s included

  • Two 7638 porcelain-enameled cast iron cooking grates (17.5" x 11.9" each) designed for even heat distribution and robust searing.
  • Five 7636 flavorizer bars (16-gauge porcelain-enameled steel, 15.3" long) that channel heat from burners to the cooking surface while reducing direct flame exposure.

Key benefits you might notice

  • Even heat distribution helps achieve consistent sear lines on beef, poultry, and vegetables.
  • Porcelain-enamel coating enhances food release and simplifies cleanup after grilling sessions.
  • Flavorizer bars improve heat flow and protect burners from grease drippings, supporting stable cooking performance.
  • Easy, one-step replacement can refresh heat balance and grill usability without a full unit replacement.

In real-world grilling, you may notice steady temperatures across the grate surface, crisper sear marks, and less sticking when turning delicate items. This kit is designed for Weber Spirit 300 Series grills with front-mounted controls (2013 and newer) and Spirit II 300 Series models sharing the same 15.3" flavorizer bar configuration, including Spirit E-310, E-320, E-330 and Spirit II S-310, S-320, S-330, as well as SP-310/SP-330 models.

Installation, compatibility, and care

  • One-step replacement: swap in the new grates and flavorizer bars, then clean with soap and water after use.
  • Not compatible with Spirit 300 grills that use side-mounted control knobs or with Spirit E-310 from 2007–2012. Please confirm your control panel style before ordering.

Note: This kit is designed to help restore heat balance and improve overall grilling usability. Results can vary with usage pattern and grill condition. Consider this upgrade as a practical way to refresh your Weber Spirit setup and keep up with regular grilling routines.
