Grill Everything to Perfection with WEBER CONNECT Smart Technology
No one likes playing guessing games on the grill, and with the Weber GENESIS SPX-435 natural gas smart grill, you no longer have to! Integrated WEBER CONNECT smart technology provides real-time temperature alerts, reminders, and flip and serve notifications right at the grill or straight to your smartphone, keeping you dialed into your cook from anywhere. The result? Perfectly grilled food and satisfied friends and family every time, with no hassle or uncertainty along the way. In short, WEBER CONNECT is your secret ingredient for the best BBQs on the block, and a big reason why this model stands as one of the biggest grilling innovations in decades.
Integrated Lights, a Side Burner, & 4 High-Performance Main Burners
This top-of-the-line GENESIS grill has all the bells and whistles, or should we say lights and burners. A pair of integrated, motion-sensing LED lights in the lid handle illuminates the entire grill surface and side tables when activated, ensuring nighttime never runs you off the grill; remote control knob lights, meanwhile, enhance visibility in the dark and add a modern aesthetic. As for the burners, the Weber GENESIS SPX-435 smart grill includes a handy side burner for sauteing veggies, boiling sides, or heating up sauces while the main grilling area takes care of the heavy lifting. Those 4 main burners feature a proprietary, ported design to produce the most efficient and even flame for consistently precise heat and reliable ignition.
Upgraded Sear Zone, Prep & Serve Table, & More
Bigger and better in all the right places, the Weber GENESIS SPX-435 natural gas grill provides more usable space than ever. Your eye will likely be drawn to the extra-large sear zone, which also received an increase in BTUs to reach the next level of delicious caramelization for the whole party. The right-hand side table is similarly sized up, with enough space for multiple cutting boards or serving trays; this extra-large prep & serve table makes it easier than ever to create entire meals without having to leave the backyard. To help you accomplish that with even greater ease, the Weber GENESIS SPX-435 natural gas smart grill trades the usual warming rack for an expandable top cooking grate that functions as a secondary grilling surface when fully folded out. Oh, and the grease management system got a facelift as well: the removable drip pan is now attached to the grease tray for seamless cleanup, with an included scraper just for good measure.
The Ultimate Versatility of WEBER CRAFTED Grillware
At this point, it would be fair to wonder if there was anything the Weber GENESIS SPX-435 smart natural gas grill is incapable of doing. Well, we have some big news on that front: compatibility with WEBER CRAFTED Outdoor Kitchen Collection grillware allows you to cook food never thought possible on a gas grill. Roast, bake, sear, steam, and even stir-fry by simply replacing the standard grate with any of the custom-fit grillware! And with the Weber GENESIS SPX-435 natural gas smart grill, you are already one step closer to the full backyard culinary experience thanks to the frame kit being built in (though the grillware itself is sold separately). This grill also includes a storage locker to keep your WEBER CRAFTED accessories, as well as certain large grilling tools, safe from the elements and close at hand.

Exactly what I hoped for! Burners-great! Sear section-great! Ease of light-up…great! And, it looks great, too! :) Oh! Easy cleaning :). My last grill lasted for about 8 years- had issues from day one. Long-term use with this one will tell, but by all indications thus far, this will be the family of grill that will be in our family moving forward.

After having an older Weber Genesis that's still performing like new after 15 years, it only made sense to have another one in our new outdoor kitchen area. I was absolutely impressed with the quality of construction while assembling this grill. And the packaging was exceptional. And after a few cooks, I'm equally impressed with the grilling experience. I can't imagine any other brand being any better.

Awesome grill. Large surface area and I was just gifted a rotisserie kit and CRAFTED griddle. Looking forward to trying out those new accessories to roast a bird and to cook potatoes, eggs, pancakes and french toast on the griddle. So far I have used it about a dozen times. I've cleaned the drip tray after a few uses. It was straightforward to remove, clean and re-insert. The porcelain-enameled cast iron grates are great as a non-stick, easy clean surface. The expandable top grate was a game changer when I hosted a backyard BBQ for 20+ people. I could easily fit 2 dozen hot dogs on there while cooking burgers on the main grates. The only issue I have had is a screw hole misalignment on the right side tray, so it is only secured with a single screw at the moment. I will eventually try to brute force the second screw to finish mounting the side tray/table surface. The instructions were unclear about the installation of the struts inside the cabinet. The instruction manual is written for the 3-burner Genesis models with an insert for a couple differences in assembly for the 4-burner Genesis models. The locker is a nice feature but is limited in space and could have been laid out with a more square aspect ratio; it is very deep and narrow which limits is storage utility. Nevertheless, this product has been excellent so far and a pleasure to operate.

Excellent grill. Two years old and it still fires up quickly and cooks evenly. We use it often, even in winter.

The new grill arrived mostly assembled, but needing the knobs and thermometer needing to be installed. The knobs were installed, but the thermometer could not be because the wing nut, which hold the thermometer to the hood, was missing. Apparently, these things are not available separately from the thermometer and also apparently, the thermometer is not available. After almost 4 weeks and counting, the grill is still not usable.

When will my item arrive?
Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we've all come to expect for small parcels, so it's important that you're prepared and understand what's required of you well before delivery day.
- Most freight products ship on a pallet
- Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
- We'll specify which process you can expect in your shipping confirmation email.
For carriers that schedule delivery appointments:
Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can't be held responsible for damages that occur during delivery. As complicated as this process may seem, we've only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.
For carriers that deliver without an appointment:
Carriers that deliver without an appointment don't require you to be home or set up a delivery window, and you aren't required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you're home at the time of the drop-off, you can request the driver place your delivery in the garage; if you're out of the house, the driver will leave it near the garage or doorstep.
