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.

Defective finish.

Bought this grill with the hope that it would be able to stand coastal living in Florida. Grill began showing rust within the first year of my owning it.

Great Grill, Cooks like a Charm

I really enjoy the feel of this BBQ—it's solid, sturdy, and has a substantial weight that gives it a premium feel. The large cooking surface provides plenty of room, easily fitting a full rack of ribs with space to spare. Heat distribution is excellent, with even cooking across the entire surface and no cold spots. My wife especially appreciates the convenient side storage area, which is perfect for keeping the new griddle we just purchased.

Great grill!

Seems to burn up more gas at a faster pace than the last Weber genesis. I recognize it has 1 additional burner as a potential culprit.

Very disappointed in Weber.

I received this grill with a damaged hood. I have had it over a month and I am told the hoods are on back order with no timeframe for replacement. Very nice customer service but not happy with replacement timelines. Gave the one star because of the kind people I have dealt with.

New S-425 what an upgrade to my previous one.

Great grill, excellent flexability with the weber craft insert capability. Heats up nicely and sear sides is perfect for meats. The stainless steel grates make cleaning much easier than cast iron.

Great except.....

Missing shelf. I didn't find out until after my purchase that the shelf in the underside cabinet is no longer provided. The have replace it with 2 (obviously much cheaper) support rods. Every piece of literature I reviewed showed a shelf underneath. They put a flyer in the instruction manual stating "the shelf is no longer required", because they found a cheaper way of support. I had plans for using the shelf. Now I have only the bottom of the cabinet with 2 bars in the way that make it difficult storing anything below.

Nice Grill!

I am replacing an old Summit Gold A4 grill. The new Genesis is a very nice grill. Fires up easily, heats up quickly and seems like a solid model. I would give 4.5 stars if that was an option. I have two negatives when compared to my old grill. It does not heat as evenly and it does not get as hot Perhaps I was spoiled. Still it is a great grill, plenty of space, nice fit and finish, solid build, indirect cooking is wonderful, grease collection works better than my old grill and is much easier to clean the drip tray. Overall a great grill I look forward to many years of happy bbqing. As an aside two pieces were slightly bent when shipped. I was able to straighten them using two blocks of wood a a few clamps, they were minor but I could not assemble the grill without straightening one of them.

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.

This item leaves our warehouse within 24 Hours

$49 Flat-Rate Shipping

Anything under $49 ships at one low price. If your order increases, your shipping stays the same!

30-Day Returns

Return all new, unused, and unassembled items in their original packaging, and we'll give you a full refund minus the cost of the original AND return shipping.

No Restocking Fee

Most companies charge a restocking fee. We just don't do business that way.
