Grill Parts Kit for Weber Genesis 300 Series - Complete Replacement

In this review the Grill Parts Kit for Weber Genesis 300 Series is assessed for owners who need a full set of replacement components that fit Genesis 300, 310, 320 and 330 models (front-mounted control panels). The bottom line: this kit is best for someone who wants a single purchase to restore a 2011-2016 Genesis 300 series grill to working order, because it supplies cast iron grates, porcelain-enameled flavorizer bars and heat deflectors plus burner tubes that are designed to fit the original part numbers for a seamless replacement.

Key Features

• Perfect Fit: Designed specifically to match Weber Genesis 300 series models with front-mounted control panels for a snug, direct replacement.
• Complete Kit: Includes 2 heat deflectors, 4 burner tubes, 5 flavorizer bars and 2 cooking grids so most common worn parts are replaced in one purchase.
• Durable Grates: Heavy-duty cast iron cooking grids retain heat well and provide an even sear while resisting food sticking when seasoned properly.
• Porcelain-Enameled Steel: Flavorizer bars and heat deflectors are 18GA porcelain-enameled steel for improved corrosion resistance and longer life compared with thinner replacements.
• Direct Part Matches: Replaces common OEM numbers such as Weber 7620/7621 flavorizer bars, 7622 heat deflector and 62752 burner tubes for straightforward swaps.
• Easy Installation: Components are made to be simple to install so you can replace worn parts and get back to grilling quickly.

Who It's For

This kit is aimed at owners of Weber Genesis E-310, E-320, E-330, S-310, S-320 and S-330 series grills from roughly 2011 to 2016 who want to replace multiple components at once rather than hunting individual parts. It suits homeowners who prefer cast iron grates for heat retention and flavor, and who want replacement parts that align with known Weber part numbers.

It is less appropriate for owners of other grill series or very recent Weber models with different dimensions, and buyers seeking stainless steel cooking grates or OEM-brand packaging should consider other options. Also, those prioritizing the thickest possible burner tubes may note mixed reports on material thickness.

Pros & Cons
