Product description

Cast Iron Grill Grates for Weber Genesis II 300 Series

These replacement grill grates are designed for Weber Genesis II 300 Series and Genesis II LX 300 Series gas grills manufactured in 2017 and newer. The set includes two cast iron grates, each measuring 18.75 inches by 13.25 inches, for a combined cooking area of 18.75 inches by 26.5 inches. Compatibility includes Genesis II models E-310, S-310, SE-310, E-315, E-325, E-330, SE-330, CE-330, S-335, SE-335, E-335, and S-345. Also fits Genesis II LX models S-340, E-340, CSE-315, CSS-315, CSS-335, CSE-335, LX CSS-340, and LX CSE-340. These grates serve as replacements for Weber part numbers 66095, 66802, and 66805, and are also compatible with KitchenAid models 720-0954 and 720-0954A. Constructed from cast iron with a total weight of 15.07 pounds, these grates provide heat retention and temperature consistency across the cooking surface. The material supports even heat distribution during grilling. The flatter top design with tighter spacing helps prevent smaller food items from falling through the grates while still creating grill marks. Each grate arrives pre-seasoned to support food release during cooking. Cast iron surfaces can develop improved release properties with regular use and maintenance. For extended durability, apply a light coating of oil before and after each use, and consider using non-metal utensils when handling food on the grates. These grates are intended for grills with control panels labeled “GENESIS II” from 2017 to current models. They are not compatible with earlier “GENESIS” models without the “II” designation, which were manufactured between 2007 and 2016. To confirm compatibility with your specific grill, refer to your model number and the data plate on your unit.

What size are these replacement grill grates?

Each grate measures 18.75″ × 13.25″. The set includes 2 pieces, covering a total cooking area of 18.75″ × 26.5″ — a true match to the original cooking surface on Weber Genesis II 300 Series grills.

Are these grates pre-seasoned, and how do I care for them?

Yes, these cast iron grates come pre-seasoned for easier food release right out of the box. For best results and longer life, lightly oil the surface before and after each use, and avoid metal tools when possible to help preserve the cooking surface over time.

Which Weber part numbers do these grates replace?

These grates are compatible replacements for Weber part numbers 66095, 66802, and 66805. They also fit select KitchenAid models, including 720-0954 and 720-0954A.

Why choose cast iron grates over other materials?

Cast iron is known for its ability to retain and distribute heat evenly across the cooking surface. At 15.07 lb total, these grates offer substantial mass that can help reduce temperature fluctuations — making them a popular choice for searing steaks, burgers, and vegetables.

Will these grates fit my Weber Genesis II grill model?

These grates fit Weber Genesis II 300 and Genesis II LX 300 series grills (2017 and newer). Make sure your grill is marked “GENESIS II”, not just “GENESIS”. If unsure, send us your model number and a photo.
