QuliMetal Genesis II 300-Series Stainless Steel Flavorizer Bars & Heat Deflectors, SUS304 5+3 Kit — Rust-Resistant, Even Heat

These QuliMetal replacement flavorizer bars and heat deflectors are direct-fit, heavy-duty SUS304 stainless steel parts engineered to replace worn Genesis II 300-series components and restore even heat, vaporization, and rust resistance.

If your Weber Genesis II or LX 300-series grill shows flaking porcelain bars, uneven cooking, or excessive flare-ups, upgrading to a full set of solid 304 stainless steel flavorizer bars and heat deflectors is a practical fix. This kit replaces common Weber part numbers (including 66032, 66795, 66685, 66040) and brings the durability of non-magnetic SUS304 stainless steel to your cooking setup. The package includes five long flavorizer plates and three smaller heat deflectors sized to match 2017-and-newer Genesis II models, so you can get consistent vaporization of drippings and a more reliable cooking surface.

How will these SUS304 bars change my grill’s performance?

Switching from porcelain-coated bars to solid 304 stainless significantly cuts down on chipping and corrosion while maintaining the flavor-producing sizzle from grease vaporization. Expect steadier heat distribution across the cooking chamber and fewer flare-ups as drippings are deflected and partially vaporized rather than igniting.

• Material: heavy-duty SUS304 stainless for corrosion and heat resistance
• Improved vaporization of juices for more consistent flavor
• Reduced porcelain chipping and long-term durability
• Designed to limit flare-ups for safer grilling

Will these parts fit my specific Weber Genesis II 300-series model?

The set is cut to match the geometry of many 300-series Genesis II and Genesis II LX grills produced 2017 and later. Before ordering, measure your existing bars and deflectors to confirm fit, as dimensions are specific and some older or different-series models may vary.

• Flavorizer bar size: 17 1/8" long x 3" wide x 2 1/8" high
• Heat deflector size: 12.5" x 4.25" (12-1/2" x 4-1/4")
• Kit contents: 5 flavorizer plates + 3 heat deflectors
• Compatible with many Genesis II (E-310, S-310, SE-310, etc.) and LX 300-series models

How do I install and maintain these replacement parts?

Installation is straightforward: remove the old bars and deflectors, check alignment and support brackets, and slot the replacement pieces into the same positions. Maintenance is simple — clean with warm soapy water or a stainless brush; avoid harsh abrasives that can dull the finish. Regular cleaning prevents buildup and preserves even heating.

• Tool-free swap in most grills—follow your grill’s manual for safe removal
• Hand-wash or brush; avoid bleach/harsh acids
• Inspect annually for warping or excessive buildup
• Store indoors in wet climates to extend lifespan

Are these flavorizer bars a good long-term upgrade over porcelain-coated alternatives?

Yes — solid SUS304 bars are a pragmatic upgrade for grill owners who want a maintenance-friendly, long-lasting solution that resists peeling and rust. They won’t promise specific cooking results, but they reduce the common failure modes of porcelain coatings and keep your grill working reliably season after season.

• No porcelain coating means no flaking or exposed base metal beneath chips
• Non-magnetic 304 grade offers strong corrosion resistance
• Manufactured dimensions match common Genesis II replacement part numbers
• Good option for frequent grillers and those replacing damaged units

Who is this for: This QuliMetal kit suits owners of Weber Genesis II and Genesis II LX 300-series grills (2017 and newer) who need a durable, rust-resistant set of flavorizer bars and heat deflectors. It’s intended for grillers seeking a like-for-like replacement that improves longevity over porcelain-coated originals, while restoring consistent heat distribution and safer vaporization of drippings. Measure your existing parts against the listed sizes and cross-check model compatibility before purchasing.
