Uniflasy Spirit E310 Grill Parts Replacement Kit — 5 Porcelain Flavorizer Bars & 2 Cast Iron Grates for Weber Spirit 300 Front-Con

Uniflasy’s Spirit E310 Grill Parts Replacement Kit refreshes front-control Weber Spirit 300 Series grills with five 15.3" porcelain flavorizer bars and two 17.5" cast iron cooking grates.

Designed as a matched replacement bundle for Weber Spirit and Spirit II 300 Series front-control models, this kit replaces worn flavorizer bars and grates in one straightforward swap. The kit pairs snow-point porcelain-coated steel flavorizer bars that protect burners and vaporize drippings with heavy-duty cast iron grates that restore heat retention and searing performance. Every component is cut to the same dimensions used by Spirit E-310 and comparable Spirit 300 models so installation and performance stay predictable.

Will these parts fit my Spirit E-310 or Spirit II 300 grill?

Yes — the kit is engineered to match the front-mounted control Spirit 300 Series lineup. That includes Spirit E-310, E-320, E-330 and S-310, S-320, S-330, plus many Spirit II 300 Series three-burner grills and select Spirit II LX 300 models.

• Flavorizer bars: five pieces, 15.3 x 2.6 x 2.5 inches — direct replacement size for 7636 references.
• Grates: two cast iron grates, each 17.5 x 11.9 inches — total cooking surface 17.5 x 23.8 inches.
• Compatible with many Spirit 300 front-control models; not compatible with Genesis Silver A.
• Confirm fit for some Genesis II LX variants before ordering.

How do the flavorizer bars improve cooking and maintenance?

The snow-point porcelain-coated flavorizer bars route drippings away from burners while turning juices into smoke for added aroma. Their porcelain finish resists early chipping and simplifies cleanup compared with bare steel, helping the burner assembly last longer.

• Porcelain coating: resists rust and chips for extended life.
• Vaporization: promotes familiar grilled flavor by converting drips into smoke.
• Burner protection: shields gas tubes from clogging and flare-ups.
• Consistent heat spread across the cook box for more even grilling.

What benefits do the cast iron grates bring to grilling performance?

Cast iron holds heat and delivers strong sear marks that elevate steaks and burgers. These bars are thick, dense, and designed to retain temperature across searing cycles, which reduces hot-spotting and produces more consistent results on high-heat cooks.

• Superior heat retention for long, steady searing capability.
• Bold sear marks and caramelization on meats and vegetables.
• Durable construction that withstands repeated heating cycles.
• Replaceable direct-fit design to restore original cooking geometry.

How straightforward is installation and ongoing care?

Installation is a simple swap-out: lift old bars and grates, drop in the replacements—no special tools required. Routine maintenance is minimal: dry-brushing and occasional oiling for cast iron plus periodic wiping of porcelain bars keeps the kit performing well season after season.

• Tool-free installation for most Spirit 300 front-control grills.
• Clean grates by brushing and oiling to prevent rust.
• Wipe porcelain flavorizer bars to remove build-up and preserve coating.
• Replace individually if only one component shows wear.

Who is this for? This Uniflasy kit is intended for Spirit 300 Series owners who want a like-for-like restoration of cooking performance and appearance — ideal if you’re replacing corroded flavorizer bars and tired grates at once. It’s a practical upgrade for backyard grillers seeking stronger sear marks, regained heat consistency, and longer-lasting porcelain protection. Confirm model compatibility before buying if you own non-Spirit models like some Genesis II LX variants.
