Product Description

Replacement GrillGrate Set for Weber Spirit 300 Series Gas Grill

GrillGrates with the GrateTool are the ultimate upgrade to your Weber Spirit 300 Series.  GrillGrates are reversible interlocking panels, giving you two grilling surfaces; rails up or on the flat side. GrillGrates tame flare-ups and even out the hot and cool spots common with all gas grills. This gives you even, stable temperatures across the cooking surface. This set is a drop-in replacement for the stock Spirit 300 Series grates. Constructed from hard anodized aluminum, GrillGrates will never rust. Made in the USA. The GrateTool is made in China.

  • Set Includes: (4) 17.375” GrillGrate panels and (1) 17.375” Gap Panel
  • Assembled dimensions = 17.375” deep x 22.5” wide
  • Designed for Weber Spirit 300 Series and older Weber Genesis® Grills pre 2007
  • Includes GrateTool and User Guide

PLEASE NOTE: If using this set on a new model Spirit, you will experience about a 2" gap. We recommend either centering the set to have a slight gap on either side or separating your grates in the middle for two-zone grilling.

  1. Absolutely fantastic! 5 Star Review

    Posted by on Apr 2nd 2020

    The moment you hold them in your hand, after unpacking, you know that is something out of the ordinary. I was "happy dancing" the all time I seasoned the GREAT Grill Grates with an onion. the rest is just a fairy tell.God bless you guys.America need more of you. Thank you!
    Thank You Ken- Your enthusiasm is contagious! Grill Grate, Eat Well & Prosper!

  2. Was going to buy a new grill but thought I’d try these first 5 Star Review

    Posted by on Nov 22nd 2019

    Really transformed my grill. I’ve used my grill now 3-4 times a week because the results are so consistent in comparison to the old grates. I really don’t experience flame-ups anymore. And while I think a lot of the the advertising materials show the raised grate side, I’ve primarily been using the flat side and getting exceptional sear and even heat distribution. Clean up is surprisingly easy and I run my grill at about 1/3-1/2 the heat settings I used to (propane savings!) a wonderful product.

  3. Revived our Silver B 5 Star Review

    Posted by on Aug 10th 2019

    Our grill is older than old, and the cast iron grates were rusted. This set fits our Weber Genesis SilverB perfectly. We’ve had them on the grill for two weeks and have been eating gourmet ever since - chicken, vegetables, hamburgers, and steaks - all succulent and done to perfection. The heat is so even, you can’t go wrong. Everyone needs to upgrade to grillgrates. You don’t know what you’re missing!

  4. Best grates ever purchased 5 Star Review

    Posted by on Aug 8th 2019

    No flare ups. With the Grill grate Temperature Guide, perfect cook every time. They truly live up to their claim. Have set for my RECTEC grill as well. Best investment I made for Grilling and Barbecuing. Thank you Grill Grates.

  5. Must have for any grill 5 Star Review

    Posted by on Jul 27th 2019

    These grates are the best thing to happen to my grill. I only used a portion of my grill due to hot or cold spots, but not any more. With the even temps all over, I have gained so much more usable space. And no longer having flare-ups is amazing!

  6. Best decision ever 5 Star Review

    Posted by on Jul 7th 2019

    I liked my grill but didn't love it. Replaced the factory grates with these and have absolutely loved my grill since. I bought a second set for my Big Green Egg.

  7. Perfect Addition for Weber Grill 5 Star Review

    Posted by on Jun 30th 2019

    The grills that I've used for years that came with the Weber have always been troublesome with food sticking and hard to clean.I saw some YouTube videos on grilling steaks and discovered GrillGrates. I wish I had known about them years ago. They provide the perfect setup for grilling, are extremely well made, and easy to clean. The Grate Tool is perfect for lifting and turning food without it breaking apart.

  8. Very impressed! 5 Star Review

    Posted by on May 30th 2019

    I was cautiously optimistic while expecting my new Grill Grates. I am happy to say the results have vastly exceeded my expectations.

    I have cooked beef, pork, chicken and vegetables since I upgraded and they all turn out better than ever before ... great grill marks, crispy seared outside, moist and juicy on the inside. I have cooked over both direct and indirect heat, everything is better!

    I am starting to compile a list of my friends who will receive Grill Grates as a gift. All of the grillers I know are going to be very happy too.

  9. SEEING IS BELIEVING 5 Star Review

    Posted by on May 2nd 2019

    I have to admit I read all the reviews on Grill Grates but was skeptical of them. How could these aftermarket grates be all that much better that the cast iron ones that came with my grill? Well I ordered some for my Weber just to say I tried them.

    I read you want to cook something fatty the first couple of times to start seasoning the grates so what better way to start a grill bonfire that some thick cut bacon. I got the grill preheated and put it to the test. Impressed does not adequately describe how I feel about this product. The bacon cooked perfectly with no flare ups or burns and was delicious. I cooked on the ridged side and the grate tool worked like a champ when flipping the bacon over. The grates/tool is a well thought out system that works wonderfully together.

    A side benefit to cooking on the grill is all the smell is outside. Previously when my wife would bake bacon in our oven the house would stink for hours.

    I have since cooked hamburgers, rib-eye steaks, plank salmon, and yes more bacon on the grates. All came out fantastic. The only adjustment I have had to make is lowering the temp setting on the grill cause them grates get hot.

    Thanks for making a “great” grate that changed me from a skeptic to a believer.

  10. Love my gas grill again! 5 Star Review

    Posted by on May 1st 2019

    Was ready to give up on my gas grill, or shop for a new one. Flare ups and constantly cleaning to keep the mice away. Thought I would give GrillGrates a try before shopping for a new grill.

    So happy I did! I love my gas grill again and use it 2 ~ 3 times per week now. All thanks to GrillGrates. In addition to eliminating flare ups, they are very easy to clean. Highly recommend the grate cleaning tool as well.
