7620 7621 Flavorizer Bars & Heat Deflectors for Weber Genesis 300

In this review the kit of replacement parts for Weber Genesis 300 series grills is judged primarily on durability and fit. The set is best for owners of the front-control Genesis models from about 2011-2016 who need to restore even heat distribution and solid build quality; the single biggest reason to buy is the heavier, solid stainless steel construction that feels noticeably more robust than thin wrapped steel replacements. Installation restored the grill's cooking performance and made it behave much like a newer unit.

Key Features

• Solid stainless steel construction: The heavier, thicker metal improves longevity compared with thin or wrapped alternatives and resists warping under high heat.
• Even heat distribution: The flavorizer bars and heat deflectors transfer and retain heat more uniformly so food cooks faster and with fewer hot spots.
• Exact fit for Genesis 300 series: Parts are sized for front-control Genesis models 2011-2016 for a straightforward replacement that restores original geometry.
• Complete set dimensions provided: Each heat deflector and flavorizer bar measures specific lengths and widths so buyers can confirm fit before ordering.
• Compatibility with common OEM numbers: Matches multiple Weber part numbers so it replaces a range of original pieces without guesswork.

Who It's For

This replacement kit suits homeowners who maintain a Weber Genesis 300 series grill with a front-mounted control panel and want a robust, long-lasting repair. It is a practical choice for users who noticed uneven cooking, rusting heat plates, or damaged flavorizer bars and prefer stainless steel for higher heat retention and durability.

It is not the right choice for owners of Genesis models with side-mounted controls, Genesis II series, Spirit 300 series, or any grill with a panel labeled GENESIS II or SPIRIT; those models have different layouts and these parts will not fit. Also, buyers expecting factory-coated finishes should note some users reported coating chipping under heavy use.

Pros & Cons

Pros

• Heavier, solid stainless steel construction improves longevity and resists warping.
• Improves heat retention and distributes heat more evenly across the cooking area.
• Fits a wide range of Genesis 300 series front-control models and matches common OEM part numbers.
• Easy to install for most users, returning grill performance to like-new behavior.

Cons

• Included screws may be smaller than expected for some grills, requiring reuse of original fasteners.
• Some customers reported coating chipping on surfaces with heavy use, so appearance may change over time.

Our Verdict

For owners of front-control Weber Genesis 300 series grills who need a practical, durable repair, this stainless steel set is a sensible value: the heavier construction restores heat performance and fit, and most buyers will find it easy to install. Those with side-control models or later Genesis II/Spirit variants should look for parts specific to their panels.
