7620 7621 Flavorizer Bars for Weber Genesis 300 Series - Durable

In this review of the 7620 7621 replacement flavorizer bars, the bottom line is straightforward: this set is for grill owners who need a direct, affordable replacement for the Weber Genesis 300 series with front-mounted controls and want bars that resist warping while restoring flavor and heat distribution. The package of five porcelain enameled bars installs easily and is sized to fit models such as the Genesis E-310, S-310 and EP-320, making it a practical choice for someone replacing worn or rusted OEM bars without paying for a dealer-only part.

Key Features

• Direct fit: Designed to replace Weber 7620 and 7621 on Genesis 300 series models with front-mounted control knobs, providing a straightforward swap.
• Porcelain enameled finish: The enamel coating helps protect the metal and promotes easier cleaning while adding a bit of smoky flavor to foods.
• 20GA thickness: A heavier 20 gauge construction improves resistance to deformation and offers longer service life than thinner aftermarket bars.
• Five-piece set: The pack includes five flavorizer bars so an entire cooking area can be renewed at once for consistent heat distribution.
• Protective packaging: The manufacturer notes careful packing to reduce transit damage and ensure parts arrive ready to install.

Who It's For

This set is best for owners of Weber Genesis E-310, E-320, E-330, S-310, S-320, S-330 and EP/CEP-310, EP/CEP-320, EP/CEP-330 grills who need a like-for-like replacement for worn or rusted flavorizer bars and prefer porcelain enameled parts for appearance and ease of cleaning. It is also a sensible option for budget-conscious shoppers who want to replace all bars at once.

It is not suitable for owners of the Genesis II 300 series or the Genesis II LX 300 series; measure your existing bars (about 17.5 in x 2.25 in x 2.375 in) before buying to confirm compatibility. Those seeking OEM-branded parts or a different finish should look elsewhere.
