Replacement GrillGrate Set for Weber Spirit 300 Series
The Best Grilling Accessory You’ll Ever Buy for your Weber Spirit 300 Series.
Nobody wants a burnt or dry meal. Flare-ups can quickly ruin any backyard cookout. At GrillGrate, we believe that grilling should be easy, fun, and stress free – every time. All you need is GrillGrates for your grill.
GrillGrates are a must-have accessory for your gas grill. Whether you sit them on top of your current grates, or use them to replace your factory grates, GrillGrates will make your old gas grill better than new. Made of hard anodized aluminum, they never rust. GrillGrates are reversible, interlocking panels, giving you two grill surfaces in one. Even out those hot and cold spots with GrillGrates and produce juicier, more flavorful food. GrillGrates make everyone a better, faster, more confident cook. The Hard Anodized Aluminum and Raised Rail design promote conductivity and control for juicier, more flavorful food. Steakhouse quality sear marks, guaranteed! Here’s why:
- Non-stick Hard Anodized Aluminum Interlocking Panels
- Two-in-One Surface; Rails Side Up for Traditional Grilling & Flat Side for Flat Top Griddling
- Rust Resistant Material
Benefits:
- Faster cooking
- Simpler grilling with better results
- Reduced flare-ups
- Versatility
- Easy to use and clean
- Light and transportable
Your Grill, But Better. As opposed to traditional grill surfaces that merely just hold the food above the heat source, GrillGrates concentrate heat through the patented raised rail design cooking food faster and more evenly. GrillGrate’s air flow vents and flat side work together to trap grease, prevent charring, and block those pesky flare-ups that tend to engulf and dry out food. When we say better, juicier food every time – we mean it! It is central to the innovative design of this grate. The sizzling-hot valleys vaporize drippings and juices, retaining moisture and enhancing flavor.

Bummer that uploading pictures doesn’t seem to be working. Would love to showoff the awesome grill marks and perfect wall-to-wall mid-rare on my first GrillGrate ribeye. I’ve cooked over a thousand steaks in my lifetime, have eaten at the top steakhouses in the U.S., nothing compares to the results I achieved an old crappy Weber Spirit 300. It’s the best ribeye I’ve ever had. I rarely take the time to review something, but this product is so good ,I had to. Get one, you’ll be happy.
Nate –
Wish I could post this review to the front page with pictures. While I purchased these for an old Weber Spirit 300, I’m certain they must deliver the same amazing results to any type of grill.
I did a lot of research (i.e. Watching a ton of youtube videos) before making the purchase. Couldn’t wait, so headed over to my local Ace hardware to get them same day.
I seasoned the grill, went to the local butcher and got a so-so ribeye (Choice, cut closer to loin side). Did my usual prep and usual cook method, only shorter time per turn.
I’m sure I’ve cooked over a thousand steaks in my lifetime I’ve had steaks from every high-end chain (Ruth’s, Mortons, Shulas, etc.) as well as famous NYC steakhouses. This steak was the best I’ve ever cooked. It was as good or better than the best I’ve ever had in any restaurant. Perfect grill marks, perfect mid-rare wall to wall, the fat rendered to butter. It was amazing. All on an old propane Weber Spirit.
I also tried smash burgers on the flat side, also worked out great. Using 23% fat content grind, zero flare ups reaching the patties.
Don’t spend thousands on a new grill, buy a GrillGrate.

Grates are great setup with one side flat and one not. Does cook hotter.but puts nice crust on hamburger (flat side).
Colorado Caveman –
Just stop reading and buy them. Greater heat retention, much more even heating, seriously a game changer for your grill.
Derrell Hickman –
Great upgrade, saved me from replacing whole grill. No more flare ups period
Bob –
Easy to install, love that I can leave one side as flat side up for burgers and other side with raised searing fins. Does get hotter and cooks faster.
William Frawley –
Wish I had these years ago. Fantastic grilling experience.
Bryan Canty –
The grates worked as expected – AWESOME! I have them on EVERY grill I own. Can’t imagine not using them.
Roger Neri –
Outfucking standing. Love it
Ty York –
Love em
Randy W Williams –
Bought these on a whim to replace the original grates that were still fine, but the bottom of the grill continued to flare up and burn anything that wasn’t cooked on super slow. Put these on and got great results almost immediately. Saved me having to buy a whole new grill.

Great point about grease and debris. On well loved grills, do clean out the bottom of your grill under the grates. You will be surprised how much fire starter builds up there. With GG in place much of the debris will stay up top in the valleys. We suggest brushing debris to the back and letting it build up at the back of your grill. Once a month or so just lift out your GrillGrates and deposit the debris in the garden or garbage. You will be surprised how clean your grill will stay. #GrillGrateful #GrillOn
Richard Robinson –
These grates are simply awesome. One thing you won’t be happy with is when it comes time to flip them from flat side to raised side. It is a holy mess. It is often that I want to use both at the same time or flip them. It is such a messy pain that I ordered another set and bought a second Weber grill. Now I am totally happy.
++++++++++++++++++++++++=
Brad here- The Scraper Tool will make quick work of the flat side and have it ready to grill in a few passes. I always have at least one panel flipped over to the flat side for a final hard sear. #grillgrateful

I had read the reviews on these and was feeling worried after I clicked “purchase”. After grilling on them for a couple months I can say the hype is justified. These grates are a game changer. Your heat will be more even, your sear marks will be second to none, and the flavor you get is a marked improvement over the standard grates. Don’t be afraid of having a little gap if they don’t cover 100% of your grill. The airflow is helpful in regulating temps and I never feel like I’ve lost any noticeable amount of space.
These are a bit pricey but if you have the money you need to do yourself the favor of buying these grates.
