The GS4 Grilling System

The Power to Bring People Together

The GS4 High Performance Grilling System sets a new standard in the world of backyard cuisine and lands the Genesis II and Genesis II LX series of gas grills in a class of their own. This innovative grilling system is based on over 30 years of grilling experience, culinary expertise, and most importantly, avidly considering the wants and needs of the people who matter most – the grilling community.

Each component of GS4 was uniquely designed for ease-of-use and to provide an unequaled satisfaction to your backyard grilling experience. Promising burners that are ensured to ignite every time, smoke-infused food that grills evenly and consistently regardless of where it’s placed on the cooking grate, and hassle-free cleanup; you are able to focus on what it’s is all about – bringing people together around the grill.

Infinity Ignition

The Infinity Ignition is guaranteed to ignite every time. An internal switch on each burner control ensures that by turning the knob, the gas will ignite and start each burner with ease. Backed by a generous warranty, rest assured that you’ll be up and-grilling the first time, every time.

High Performance Burners

The unique, tapered shape delivers a consistent gas flow from front to back. This provides ultimate heat distribution, ensuring that food grills evenly and consistently anywhere on the cooking grate.

Flavorizer Bars

The classic Weber Flavorizer bars are angled just right to catch drippings that smoke and sizzle, adding that irresistible smoky flavor we all know and love to your food. Any drippings not vaporized follow the slope and are funneled away from the burners, down into the grease management system.

Grease Management System

The grease management system helps with the removal of grease while reducing the risk of flare-ups. Drippings that are not vaporized by the Flavorizer bars are funneled away from the burners into the disposable drip tray, located within the catch pan under the cookbox. Simply remove the catch pan and replace the drip tray as needed.

Stainless Steel Cooking Grates

Premium stainless steel rod cooking grates provide even heat distribution across the entire grilling surface and retain heat for chef-inspired sear marks. Made of high-quality stainless steel and built to last.


All burners can be turned up to the highest setting for an added boost of heat anywhere on the cooking grate. The High+ setting provides a quicker preheat and higher grilling temperatures.

Side Tables with Integrated Tool Hooks

Use the side tables to keep platters, seasonings, and tools within arm’s reach. Hang your essential grilling tools on the hooks for easy access and organization of your backyard workspace. The side table folds down in models equipped with two and three burners.

Tuck-Away Warming Rack

The Tuck-Away warming rack keeps food warm or toasts burger buns, as the main meal grills below. The unique Tuck-Away feature allows you to fold it down when not in use, providing optimal grilling space and convenient in-the-grill storage.

Handle Light

The powerful LED illuminates the entire cooking area of the grill so that you see the true color of your food. To save energy, the light will automatically turn off when the lid is closed.

Lighted Control Knobs

With a push of a button, the control knobs light up to offer optimal control while night-time grilling. Whether throwing a dinner party, or a daytime BBQ, you’ll never have to sacrifice convenience or usability due to the time of day.

Side Burner

Use the side burner to simmer your specially crafted BBQ sauce while the main course grills under the lid.

iGrill3 Ready

The iGrill 3 Bluetooth digital thermometer monitors your food from beginning to end, displaying the real-time temperature, and fuel tank level, on your mobile device. (Sold separately.)
