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 propane 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 propane 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 propane 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 propane 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 propane 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.

This is my second Genesis, 1st one was bought in 2014 and was a great grill until this spring when things started to go wrong. My old one was outdoors in all weather, but always covered in a weber cover - renewed every two years. So with the issues I bought a new updated one.... Buying and having delivered was easy....the delivery guys even brought the BIG HEAVY box round the back for me. The unit was very well packed and the instructions could not have been clearer, the labelled boxes and screw packets made life very easy. I put the whole thing together in less than two hours. But there were a few issues.....the tank blocker bracket was missing - they sent a replacement with minimum of effort on my part......the plastic fittings for fitting the lower/ floor shelf were useless and did not fit the holes they were meant to go into.....I ended up throwing them away and using some stainless steel bolts washers and nuts that I had. I like the new burner system, works very well. The new foldable top rack is also very nice for extra surface when needed.....I use it for keeping things warm rather than cooking. The under unit storage compared to my old one was also much improved. I did feel the SS outer skin was not as thick as my old one and already has a slight dent, the old one was ten years old and from the outside looked as good as the day it was delivered.....I wonder how durable this new one will be??? The knobs on the new one are much less solid and seem plastic whereas I think the old ones were metal, so again I will be interested in durability. Overall I love the new grill, it looks nice and cooks very well - we grill 2-3 times a week in Spring/ Summer/ Fall

As always, an excellent product from Weber. I'm really enjoying the "Sear Zone" as it grills up steaks nicely. Still getting into the different grates you can use for the area and I like having options. The built in smart options are good and had no issues setting them up. My third Weber grill and I can't imagine ever using another brand.

Bought this grill a couple months ago and am very pleased overall with its performance during the dozen or so grilling sessions in that time. The grill is quite an upgrade from my (very) old Thermos grill. as it cooks quickly and evenly. The extra "Sear" burner works as advertised and is a great plus, in my opinion. The grill looks very nice, is well made and solid. The grates are easy to clean, which I did not expect, so a pleasant surprise there. My only (nitpicking to be sure) complaint is that the top of the lid is completely flat and rain water pools and just sits there until it evaporates. I think the lid should be designed with at least a slight curve on top, so that rain water runs off.

I've owned many Weber grills, but this is the first with four burners. The searing burner actually makes it 5 and is great for searing steaks. The extra size really comes in handy when grilling different foods that require different temperatures. The assembly process is straightforward and didn't take but a couple hours. The one gripe I have is that every time I've gotten a new Weber grill, the knobs get thinner and lighter and this one is no different. I'd like the tactile feel of a heavier knob but it's certainly not a deal breaker. I love cooking on 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.
