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.

Great customer service! I was able to talk to a real person who helped solve my issue me with just one phone call. It's hard to find this kind of good customer service these days. Thank you!

In the 80's I purchased my first Weber grill and it was the table top charcoal grill which servved me well for many years into the 1990's. In 2000 I retired and moved to Florida from New Hampshire and purchased my first 3 burner natural gas Weber. It served mecwell for over ten years when rust took over and I purchased my second natural gas Weber. I always had covers for my grills but this one succumbed to rust at the legs and even a door hinge when It was only about 6 years old. The Florida salt air is a killer even though I was about ten miles inland from the mighty Atlantic. I contacted Mother Weber by phone with my pronlem and in less than a month, I received a call that a new Weber would be delivered the next day from Orlando, to my surprise. The next day it arrived and was assembled and hooked up to my quick connect outlet. I moved further inland, about 15 miles from the mighty Atlantic in the summer of 24 to a 55 community and Just purchased the stainless four burner and extra side burner model propane Weber. My new home now has a large propane installed and I will have a quick connect propane hose hooked up to my "Beauty" in the near future so I will no longer need the smaller tanks. I am 78 years old and looking forward to many more years of use of my Weber product!

Great grill with all the features that you need. The left bottom door doesn't close too well, seems like there could be an issue with the magnets.

I ordered a replacement part that was supposedly in stock and promised to arrive in 2 days. Instead, it took a full week to get to me. No receipt or tracking information was ever sent, leaving me in the dark about the status of my order. When I called to speak to a manager, I was left on hold for an absurd amount of time. The company claims to value customers' time, but their actions show the complete opposite. Extremely disappointed with the service and lack of communication.

Really enjoying our new Weber. Side burner comes in handy when frying messy dishes. The grill segments allow for customized cooking and adjustable heat. Looking forward to using this grill for many years. It also looks great!

I bought this grill with summer in mind, wanted to get a little more grill than i needed for the occasional large cooks. Performs admirably, plenty of cooking surface and I love the fact that low heat is really a low heat not just a knob setting.

this gas grill is ok. the electronic were hanging down; they must have not been connected adequately. the manual is not easy to follow. I'm having a hard time connecting the power cord to the unit. I was expecting more for a high priced grill.

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 10-14 Business Days
$6.95 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.
