66032 Flavorizer Bars & Heat Deflector Kit for Weber Genesis II 300 Series (2017+)

What this is

This replacement kit is designed for Weber Genesis II 300 and Genesis II LX 300 series gas grills from 2017 onward. It combines flavorizer bars and heat deflectors to restore heat distribution and protect burners after wear.

What it does for you

On the grill, the five 17 1/8" x 3" x 2 1/8" stainless bars are 17-gauge thick and crafted from non-magnetic SUS304 stainless steel for corrosion resistance and high-temperature stability. The three heat deflectors (12-1/2" x 4-1/4") sit beneath the bars to guide heat evenly and shield burners from drippings. This setup aims to recreate consistent cooking temps across the grate, reducing heat hotspots and helping to maintain steady flames.

Build and materials

Real SUS304 stainless steel, not porcelain-coated, so there’s less risk of chipping or exposing bare metal. The thicker 17GA bars are tougher than typical replacements, which can help with longer service life in active grilling environments.

Pros and practical notes

It offers a practical, all-in-one replacement that covers multiple worn components at once, which can simplify maintenance and restore performance without buying parts separately. The stainless construction also means easier cleanup and reduced maintenance compared to coated alternatives.

Limitations and things to check

Before ordering, match your grill model and the original part size. This kit is tailored for 2017+ Genesis II 300 and LX 300 series, and a mismatch may mean you’ll still need a different part. While the kit covers several common Weber replacements, it may not fit every variation of the Genesis II lineup.

Who it’s for

If your Genesis II 300-series grill shows signs of heat unevenness, burner protection concerns, or drippings that affect flame quality, this kit offers a straightforward upgrade path. It’s a sensible option for grill owners seeking a long-lasting, non-magnetic stainless solution rather than porcelain-coated replacements.

Who should consider alternatives

If your setup isn’t in the 2017+ Genesis II 300/LX 300 family, or if you’re looking for specific OEM parts only, you may want to verify model compatibility more closely or opt for parts labeled exactly for your grill year and series.

When it makes sense to buy

Choosing this kit makes sense if you want a consolidated replacement that improves heat distribution and burner protection, with the reassurance of stainless steel construction and thicker bars for durability.

What to review before purchase

• Confirm your grill model and part sizes match the kit components.
• Note that these are non-magnetic SUS304 stainless pieces, if you need magnetic steel or a porcelain-coated alternative, this kit isn’t for you.
• Consider whether you prefer a single-pack replacement of multiple worn parts rather than piecemeal replacements.

Practical usage snapshot

Imagine a weekend cook where you’ve noticed uneven heat across the grate and minor flare-ups from dripping fat. Replacing with these flavorizer bars and heat deflectors can help stabilize heat and maintain consistent sear performance, letting you focus on turning out steady results rather than babysitting flames.

The bottom line (Is it worth it?)

It’s worth considering if your Genesis II 300-series grill is in need of a durable, corrosion-resistant replacement that covers both flavorization and heat deflection in one kit. If you prioritize long-term durability and straightforward maintenance, this setup offers clear benefits, though you’ll want to double-check compatibility to avoid fit issues.
