Grill Replacement for Weber Genesis 300 Series - Complete Rebuild Kit

Our review of this Grill Replacement kit for Weber Genesis 300 series finds it best suited to owners who need a practical, full replacement set that restores performance without a full new grill. The kit bundles 5 flavorizer bars, 2 cast iron grill grates, 4 stainless burner tubes and 2 heat deflectors to match many original Weber part numbers, so the single biggest reason to buy is convenience: it replaces multiple worn parts in one purchase and fits Genesis 300 models with front control knobs from 2011-2016. Installation is straightforward for most DIYers and the materials aim to improve longevity and searing performance.

Key Features

• Complete kit: Includes flavorizer bars, grill grates, burner tubes and heat deflectors so you can replace all major cooking components at once.
• Wide compatibility: Designed to fit Genesis 300 series gas grills with front control knobs, including E310, E320 and E330 models from 2011-2016.
• Durable materials: Flavorizer bars and deflectors use upgraded snowflake porcelain-enameled steel for corrosion resistance and heat management.
• Cast iron grates: Matte enamel cast iron grates heat up quickly and improve searing and overall cooking performance.
• Stainless burner tubes: Four stainless steel burner tubes replace worn burners to restore consistent flame and heat distribution.
• Direct-fit replacements: Matches common original part numbers like 62783, 7622 and 7524 so fitment is straightforward when dimensions match.

Who It's For

This kit is for owners of Weber Genesis 300 series grills (front control knob models) who want to replace multiple aging or damaged parts at once. It is particularly useful for people restoring a 2011-2016 E310, E320, E330, S310, S330 or similar model and who prefer components that mimic original part numbers and sizes.

It is not ideal for owners of Genesis II 300 or Genesis II LX series, or for buyers who cannot confirm model numbers and original part dimensions. If you need only a single part or have an uncommon model, individual OEM components or a different kit may be a better choice.

Pros & Cons

Pros

• Replaces multiple wear items in one purchase, saving time and matching many original part numbers.
• Porcelain-enameled bars and deflectors resist rust better than bare steel when maintained properly.
• Enamel cast iron grates improve heat retention and searing compared with thin wire grates.
• Stainless burner tubes restore flame consistency and reduce corrosion risk.

Cons

• Build quality reports are mixed: many buyers find excellent durability while some received damaged pieces in transit.
• Not compatible with Genesis II 300 or LX series, so careful model verification is required before purchase.

Specifications

Our Verdict

Verify model and dimensions carefully, but for the right grill this kit is a cost-effective way to rebuild key components and extend the life of the barbecue.
