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.

The best grill I've ever had! I've had lower quality grills in the past and the Weber is by far the best you can buy.

Overall the regular grilling is up to Weber standards. But very disappointed with the flattop. While the cabinet is a great addition the quality of the flattop is poor. It rusts so fast and badly I never use it.

When the grill was delivered to my home and Im opened the package I found the front and the rear frame damaged. After 6 phone calls to Weber I finally was able to understand the customer service person and get those parts ordered. Yet to find out that the front frame piece was backordered and after 3 weeks is supposed to be deklivered in the next few days. I then poroceedded to inspect the parts that were in numerous separate boxes only to find that a part on the body of the grill was also bent/damaged. After 3 more calls I was able to get that part ordered. After a week or so the I recieve 2 of the pieces but get an email about the front frame piece expected to ship in a few days. To say I'm not happy is an understaement. so I decide to assemble the grill with the damaged front frame piece figuring I'd can swap the part when it arrives. I migh add that thei assembly instructions are very poorly done as well. 3 hiours later I get the grill together, only to find that another part is missing. So after 3 more calls, I get that part ordered. So it's now been 3 weeks and I'm notified that the front frame piece has finally shipped. Bring in northern PA the has quickly changed so that grilling probably won't happen to spring. The only positive thing I can say at this point is that Weber didn't question the issues and did ship the parts at no charge. Which I would have expected. I've always heard how great Weber is and how good their product works. Maybe I'll find out in April but so far I've not been impressed.

This is my first big, real, propane grill and it's amazing. Start ups and ready to grill in minutes. The flat top is super fun for pancakes, zucchini, bacon, anything! It's insanely easy to make the best steaks / chicken. I tried fried rice on the wok and it's super fun too. I did have to call Weber for a very small item, and their customer service was amazing. They had this cool thing there I could video call to show them the issue, and they would draw on my screen. Fixed two minor issues in 5-10 minutes without having to leave the house (issue was third party assembly issue, NOT Weber's) With how much I love this, I'm already looking for a Weber travel grill soon!

My old reliable Weber Silver C finally aged out after 27 years. :( Terrible timing for my bank account as I had just bought a new Weber Slate a month earlier. I had been looking at the 435 knowing the day was coming soon. Honestly, I told myself there is no way this new Weber would be as well built as my old one. Things seldom are these days. I could not have been more wrong! I fell in love after cooking on it the first time! This Genesis is so well engineered and built. I love how much space I have on this grill. So many more options for indirect grilling or just keeping things warm. I did opt for the black enamel finish. I just didn't think the stainless would retain its looks as well here in my part of the country as it is so humid here. I should say I did purchase mine as a scratch & dent. It was missing the front handles for the cabinet doors but otherwise perfect, thus I got a great discount. However, I would not hesitate to pay regular price to get this 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.

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.

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