What to know before buying

Listing details to confirm

The listing gives conflicting grate dimensions: 18 3/4'' L in one package description and 18 4/5'' L in another. It also describes fitment across different Genesis generations and years, so confirm your grill's exact model and year and compare each original part's dimensions before ordering. The listed overall product dimensions of 0.1 x 0.1 x 0.1 inches appear inconsistent with the component dimensions. The claimed compatible part numbers and fit are not independently confirmed.

Who is it for?

A good fit for

Owners of a listed compatible Genesis II 300 or Genesis 300 grill replacing grates, Flavorizer bars and heat deflectors together.
Buyers comfortable checking grill model, year and replacement-part measurements before purchasing.

Less suited to

Owners of Weber Genesis 300 grills from 2007–2016, which the listing explicitly excludes.
Anyone seeking a replacement set without first confirming the grill's generation and part dimensions.

Customer feedback highlights fit and perceived quality, including a positive mention of the Flavorizer bars and deflectors. That feedback may be relevant to buyers replacing the complete set, but it does not establish compatibility with every listed grill model. Ratings are mostly five-star with some two-star ratings, so experiences are not uniformly positive.
